| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| UNIT YYYYYYYY PRECHARGE - LOW DC BUS VOLTAGE SYS X YYYYYYYY PRECHARGE - LOW DC BUS VOLT | Software-generated VSD fault detected during DC bus pre-charge. First message is a unit fault (2 or 3 compressor chillers); second is a system 1/3 or 2/4 fault on 4-compressor units. YYYYYYY indicates the system/unit is in a "FAULT" condition and will restart when the fault clears, or "LOCKOUT". | The DC bus voltage must reach at least 50 VDC within four seconds and 500 VDC within 19 seconds after the pre-charge signal has been asserted. If not, the unit/system shuts down on a fault. | Auto-restart safety; locks out on the 3rd fault in 90 minutes. On lockout, will not restart until the operator clears the fault using the keypad. | 203 |
| UNIT YYYYYYYY PRECHARGE - DC BUS VOLTAGE IMBALANCE SYS X YYYYYYYY PRECHARGE-BUS VOLT IMBAL | Software-generated VSD fault detected during the pre-charge interval. Unit fault for 3-compressor units; system 1/3 or 2/4 fault for 4-compressor units (two presses of the STATUS key required to show the fault on both systems). YYYYYYY indicates a "LOCKOUT" condition. | The 1/2 DC bus voltage magnitude must remain within +/- 100VDC of the total DC bus voltage divided by two during the pre-charge interval. If not, the unit/system shuts down on a fault. | Locks out on the 1st fault; will not restart until the operator clears the fault using the keypad. | 203 |
| UNIT YYYYYYYY HIGH DC BUS VOLTAGE SYS X YYYYYYYY HIGH DC BUS VOLTAGE | Hardware-generated VSD fault. Unit fault for 3-compressor units; system 1/3 or 2/4 fault on 4-compressor units (two STATUS key presses required to show the fault on both systems). YYYYYYY indicates a "FAULT" condition (restarts when cleared) or "LOCKOUT". | Trip level is determined by hardware on the VSD Logic Board and is designed to trip the unit at 766 +/- 30 VDC. If the DC bus exceeds this level, the unit/system faults and shuts down immediately. | Auto-restart safety; locks out on the 3rd fault in 90 minutes. On lockout, will not restart until the operator clears the fault using the keypad. | 203 |
| UNIT YYYYYYYY LOW DC BUS VOLTAGE SYS X YYYYYYYY LOW DC BUS VOLTAGE | Software-generated VSD fault. Unit fault for 3-compressor units; system fault (1/3 or 2/4) on 4-compressor units (two STATUS key presses required to show the fault on both systems). YYYYYYY indicates a "FAULT" condition (restarts when cleared) or "LOCKOUT". | The low DC bus voltage trip level is set at 500 VDC. If the DC bus drops below this level the unit/system faults and immediately shuts down. | Auto-restart safety; locks out on the 3rd fault in 90 minutes. On lockout, will not restart until the operator clears the fault using the keypad. | 204 |
| UNIT YYYYYYYY DC BUS VOLTAGE IMBALANCE SYS X YYYYYYYY DC BUS VOLTAGE IMBALANCE | Software-generated VSD fault. Unit fault for 3-compressor units; system 1/3 or 2/4 fault on 4-compressor units (two STATUS key presses required to show the fault on both systems). YYYYYYY indicates a "LOCKOUT" condition. | The 1/2 DC bus voltage magnitude must remain within +/- 100 VDC of the total DC bus voltage divided by two. If the 1/2 DC bus magnitude exceeds the +/- 100 VDC tolerances, the unit/system faults and immediately shuts down. | Locks out on the 1st fault; will not restart until the operator clears the fault using the keypad. | 204 |
| SYS X YYYYYYYY HIGH MOTOR CURRENT | Hardware-generated VSD fault; individual system/compressor fault for all units. YYYYYYY indicates a "FAULT" condition (restarts) or "LOCKOUT". | The three output lines to each phase of the compressor motor are monitored via three current transformers; instantaneous output current is compared to a predetermined hardware limit. Nominal peak current trip level is 575.5 Amps (554A min., 597A max.); 380V AC, 60Hz and 400V AC, 50Hz nominal peak current trip level is 649.5 Amps (626 Amps min., 674 Amps max.). Variation in trip point results from component tolerances on the VSD Logic Board. If the peak current limit is exceeded, the unit faults and shuts down immediately. | Auto-restart safety; locks out system on the 3rd fault in 90 minutes. On lockout, will not restart until the operator clears the fault using the keypad. | 204 |
| SYS X YYYYYYYY MOTOR CURRENT OVERLOAD | Software-generated VSD fault; individual system/compressor fault for all systems, shutting down with a controlled ramped shutdown. YYYYYYY indicates a "LOCKOUT" condition. | Compares the highest of the 3 phases of motor current per compressor to the compressor's 105 % FLA ADJUST (overload) potentiometer setting on the VSD Logic Board. If the current exceeds the setting continuously for 20 seconds, the compressor trips. | Locks out a system on the 1st fault; will not restart until the operator clears the fault using the keypad. | 205 |
| UNIT YYYYYYYY MOTOR CURRENT OVERLOAD | Hardware-generated VSD fault; unit fault that locks out all systems on the first fault. YYYYYYY indicates the unit is in a "Lockout" condition. | Compares the highest of the 3 phases of motor current per compressor to the compressor's overload ADJUST potentiometer setting. If the current exceeds the setting continuously for 30 seconds, all compressors fault and shut down immediately. | Locks out all systems on the first fault; will not restart until the operator clears the fault using the keypad. | 205 |
| SYS X YYYYYYYY GATE DRIVER | Hardware-generated VSD fault; system fault for all units. YYYYYYY indicates a "FAULT" condition (restarts) or "LOCKOUT". | Each phase bank assembly contains one IGBT gate driver control board per compressor, monitoring the saturation voltage drop across each of the six IGBTs while gated on. If the IGBT's saturation voltage exceeds the prescribed limit, the gate driver determines a short circuit is present, immediately turns off all IGBTs in the module and the system shuts down immediately. The same fault is generated if the IGBT Gate Driver board's power supply voltage falls below the permissible limit. | Auto-restart safety; locks out on the 3rd fault in 90 minutes. On lockout, will not restart until the operator clears the fault using the keypad. | 205 |
| SYS X YYYYYYYY HIGH VSD BASEPLATE TEMP | Software-generated VSD fault; system fault for all units. 3-compressor chillers operate at higher baseplate temperature compared to 4-compressor chillers. YYYYYYY indicates a "FAULT" condition (restarts when cleared) or "LOCKOUT". | Each compressor's inverter power module contains an internal temperature sensor (5K ohm at 25 Deg. °C) monitoring baseplate temperature. On 3-compressor chillers, baseplate temperatures on compressors 1 and 3 are OR'd together and the highest compared in software to a limit of 232°F; compressor #2's individual power module sensor is compared to a limit of 232°F. On 4-compressor chillers, baseplate temperatures on compressors 1 and 3 are OR'd together and compressors 2 and 4 are OR'd together, each compared in software to a limit of 218°F. If the limit is exceeded by either input, the unit faults and shuts down with a controlled ramped shutdown. | Auto-restart safety; locks out on the 3rd fault in 90 minutes. After a fault, the fan(s) and water pump remain energized until the inverter power module base plate temperature(s) falls below 165°F; the system is allowed to restart when the base plate temperatures drop below this value. On lockout, will not restart until the operator clears the fault using the keypad. | 206 |
| UNIT YYYYYYYY HIGH VSD INTERNAL AMBIENT TEMP | Software-generated VSD fault; unit fault for all units. YYYYYYY indicates the unit is in a "Fault" condition and will restart when the condition clears. | The VSD Logic Board contains a temperature sensor monitoring the unit's internal ambient temperature. If the VSD internal ambient temperature rises above the cutout of 158°F, the unit faults and shuts down with a controlled ramped shutdown. | This safety will not cause a lockout. The unit will be allowed to restart when the internal ambient temperature drops 10°F below the cutout. | 206 |
| UNIT YYYYYYYY SINGLE PHASE INPUT VOLTAGE SYS X YYYYYYYY SINGLE PHASE INPUT VOLTS | Hardware-generated VSD fault. Unit fault for 3-compressor units; system fault 1/3 or 2/4 for 4-compressor units (two STATUS key presses required to show the fault on both systems). YYYYYYY indicates the system is "FAULT" and will restart when the single phase condition clears. | The VSD's SCR Trigger Control board contains circuitry that checks the three phase mains for the presence of all three-line voltages. If any of the line voltages are not present, the system immediately shuts down on a fault. | This fault will not cause a lockout; restarts when the single phase condition clears. | 206 |
| UNIT YYYYYYYY VSD LOGIC BOARD POWER SUPPLY | Hardware-generated VSD fault; unit fault for all units. YYYYYYY indicates a "FAULT" condition (restarts when cleared) or "LOCKOUT". | Various DC power supplies which power the VSD Logic Board are monitored via hardware located on the logic board. If any of these power supplies fall outside their allowable limits, the unit immediately shuts down on a fault. | Auto-restart safety; restarts after the fault clears and locks out on the 3rd fault in 90 minutes. On lockout, cleared using the keypad. | 207 |
| SYS X YYYYYYYY VSD RUN RELAY | Software-generated VSD fault; combined as a 1/3 or 2/4 system fault. YYYYYYY indicates a "FAULT" condition (restarts when cleared) or "LOCKOUT". | Upon receipt of either of the two types of run commands (hardware and software) a 5 second timer commences timing. The hardware run signal comes from the SYS X VSD Run Signal to the VSD Logic Board; the software run signal comes through the comms from the Chiller Control Board. If the missing run signal is not asserted within the 5-second window, the system faults. In addition, if either run signal is disabled while the VSD is running, the remaining run signal must be disabled within 5 seconds after the VSD is shut down or the system faults. If running, the unit faults and shuts down with a controlled ramped shutdown. | Auto-restart safety; will autostart after the 120 second anti-recycle timer times out and locks out on the 3rd fault in 90 minutes. On lockout, will not restart until the operator clears the fault using the keypad. | 207 |
| UNIT YYYYYYYY VSD LOGIC BOARD FAILURE | Software-generated VSD fault; unit fault for all units. YYYYYYY indicates a "FAULT" condition (restarts) or "LOCKOUT". | Upon receipt of the voltage and frequency commands, the PWM generator must acknowledge receipt of the command. If the system microprocessor does not receive the handshake within 1.5 seconds of issuing the command, the unit trips. This safety is only active during precharge and during running of a compressor; it is not active when all compressors are shut down and the precharge is disabled. If the fault occurs while the chiller is running, all systems immediately shut down on a fault. | Auto-restart safety; auto restarts after the 120 second anti-recycle timer times out and locks out on the 3rd fault in 90 minutes. On lockout, cleared using the keypad. | 207 |
| UNIT YYYYYYYY VSD CT PLUG FAULT | Hardware-generated VSD fault; unit fault for all units. YYYYYYY indicates a "FAULT" condition (restarts) or "LOCKOUT". | Jumpers are installed in each CT plug on the VSD Logic Board to feed back signals indicating if the plugs are installed or not. If either plug is not installed, a low value is read on the digital input and the unit will immediately shut down on a fault or will not run if off. | Auto-restart safety; restarts after the 120 second anti-recycle timer times out and locks out on the 3rd fault in 90 minutes. On lockout, cleared using the keypad. | 207 |
Unit Warnings
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| UNIT WARNING: !! LOW BATTERY !! CHECK SETPOINTS/PROGRAM/OPTIONS/TIME | Warning displayed indefinitely at micropanel power-up when the RTC battery voltage is determined to be low. Warnings are not logged to the history buffer. | On micropanel power-up, the RTC battery is checked to see if it is still operational. If the battery voltage is determined to be low, the warning message is displayed indefinitely. If a low battery condition exists, all programmed setpoints, program values, time, schedule, and history buffers will have been lost and reset to their default values, which may not be the desired operating values. | Once a bad battery is detected, the unit is prevented from running until the MANUAL OVERRIDE key is pressed. Once the MANUAL OVERRIDE key is pressed, the anti-recycle timers are set to the programmed default anti-recycle time to allow the operator sufficient time to check setpoints, program values, etc. If a low battery is detected, it should be replaced as soon as possible; the programmed values will all be lost and the unit will be prevented from running on the next power interruption. | 210 |
| UNIT WARNING: INVALID NUMBER OF COMPRESSORS SELECTED | Warning displayed indefinitely after the VSD has been initialized. | Occurs if no "Number of Compressors Select" jumpers are installed or if more than 1 jumper is installed. | To clear this warning, both the control panel and VSD control voltage must be turned off and the jumpers properly installed in the VSD wiring harness. These jumpers are factory installed in the wire harness plug and should not require changes. | 213 |
| UNIT WARNING: INVALID SERIAL NUMBER ENTER UNIT SERIAL NUMBER | Warning indicating the chiller may have lost important factory programmed information; when displayed, an Optimized IPLV chiller will only run in Standard IPLV control mode. | The appearance of this message may mean the chiller has lost important factory programmed information. | Immediately contact YORK Product Technical Support. The serial number can be entered using the Service Key. Optimized IPLV cannot be enabled unless the serial number is programmed into the unit using the special password supplied by YORK Product Technical Support; once the password is entered, a second password is needed to activate the optimized IPLV control. This status message can be bypassed to view additional messages under the STATUS key by pressing the STATUS key repeatedly. | 213 |
| UNIT WARNING: OPTIMIZED EFFICIENCY DISABLED - CONTACT YORK REPRESENTATIVE | Warning that an optimized chiller is programmed for standard control. | The appearance of this message means an optimized chiller is programmed for standard control. | Immediately contact YORK Product Technical Support or YORK ES Commercial. Optimized IPLV cannot be enabled unless a special password is entered; once the password is entered and the option is enabled using the Service Key, the message will disappear. This status message can be bypassed to view additional messages under the STATUS key by pressing the STATUS key repeatedly. | 213 |
Unit Safeties
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| UNIT YYYYYYYY LOW AMBIENT TEMP | Unit safety; shuts down all running compressors with a controlled ramped shutdown. Cannot cause a lockout. | The ambient temperature falls below the programmable Low Ambient Temp Cutout. This fault only occurs if the Low Ambient Cutout is "ENABLED" under the OPTIONS key. | Restart can occur, if demand allows, when temperature rises 2°F above the cutout. The fault display message is present only during the time the ambient temperature is causing a fault condition. The unit is also inhibited from starting any time the temperature is below the cutout + 2°F. | 214 |
| UNIT YYYYYYYY LOW LEAVING CHILLED LIQUID TEMP | Unit safety helping to protect the chiller from an evaporator freeze-up should the chilled liquid temp drop below the freeze point. Cannot cause a lockout. | Any time the leaving chilled liquid temperature (water or brine) drops below the programmable cutout point. This situation could occur under low flow conditions or if the micro panel setpoint values are improperly programmed. | Shutdown with a controlled ramped shutdown. Restart can occur, if demand allows, when chilled liquid temperature rises 4°F above the cutout. The unit is inhibited from starting any time the chilled liquid temperature is below the cutout + 4°F. | 215 |
| UNIT YYYYYYYY VSD COMMUNICATIONS FAILURE | Unit safety to prevent the unit from trying to run if the Chiller Control Board never initializes communications with the VSD Logic Board. | On power-up, the Chiller Microprocessor Board attempts to initialize communications with the VSD Logic Board, requesting the number of compressors and the VSD software version; if the comms connection fails to occur, the Chiller Control Board prevents the chiller from operating. During normal operation, if the Chiller Control Board receives no valid response to messages for 8 seconds, the unit shuts down all compressors on a Comms fault. | Unit shut down with a controlled ramped shutdown; inhibited from starting until communications is established. The Chiller Control Board continues to send messages to the VSD while faulted. The fault automatically resets when the Chiller Control Board receives a valid response from the VSD for a data request. | 215 |
System Safeties (Faults)
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| SYS X YYYYYYYY HIGH DISCHARGE PRESSURE | Software system safety; the system faults and shuts down with a controlled ramped shutdown. YYYYYYY indicates a "FAULT" condition (restarts after the 120 second anti-recycle timer times out) or "LOCKOUT". | The discharge pressure rises above 274 PSIG for 0.5 seconds. | The system is allowed to restart when the discharge pressure falls to 259 PSIG; the system is also inhibited from starting if the pressure is above 259 PSIG. On lockout, will not restart until the operator clears the fault using the keypad. | 216 |
| SYS X YYYYYYYY HPCO FAULT | Mechanical high pressure cutout protecting the system from experiencing dangerously high discharge pressure; hardware fault that occurs immediately and does not wait the 3 seconds typical of most system faults. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | The mechanical high pressure cutout contacts open. The HPCO is wired in series with the VSD Run Signal and will only be checked by the Chiller Control Board when the system is running. The mechanical cutout opens at 297+/-8 PSIG and closes at 230 +/-10 PSIG. | Immediate fault and shutdown. Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 217 |
| SYS X YYYYYYYY LOW SUCTION PRESSURE | Programmable cutout serving as a secondary back-up for the flow switch; protects against operation with low refrigerant charge, helping protect the chiller from an evaporator freeze-up. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | Suction pressure falls below the programmable cutout (typically set at 24 PSIG for chilled water applications). The cutout is ignored for the first 30 seconds of system run time; during the next 3 minutes of run time the cutout point is linearly ramped from 10% of the cutout value up to the programmed cutout point (Cutout = ((Programmed Cutout x Run Time) / 200) – 1.2 PSIG). After the first 3 minutes 30 seconds of run time, if the suction pressure falls below the cutout as a result of a transient, a 30 second transient timer is set with a linearly ramped cutout starting at 10% of the programmed cutout; if over the next 30 seconds the suction pressure does not stay above the ramped cutout, the system faults. | Controlled ramped shutdown. Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 217 |
| SYS X YYYYYYYY LOW MOTOR CURRENT | Shuts the system down when the microprocessor detects the absence of motor current, usually indicating that a compressor is not running. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | Motor current below 10%FLA. This safety is ignored for the first 10 seconds of operation. | Controlled ramped shutdown. Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 217 |
| SYS X YYYYYYYY HIGH DIFF OIL PRESSURE | Protects the compressor from low oil flow and insufficient lubrication, possibly from a dirty oil filter. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | Discharge to Oil Differential Pressure rises above the cutout of 65 PSID. This safety measures the pressure differential between discharge and oil pressure, which is the pressure drop across the oil filter. The safety is ignored for the first 90 seconds of run time. | Controlled ramped shutdown. Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 218 |
| SYS X YYYYYYYY LOW DIFF OIL PRESSURE | Protects the compressor from low oil flow and insufficient lubrication; assures the compressor is pumping sufficiently to push oil through the oil cooling circuit and the internal compressor lubrication system. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | Differential between oil and suction pressure falls below the cutout. The safety is ignored for the first 60 seconds of run time; after the first 60 seconds of operation, the cutout is linearly ramped from 0 PSID to 30 PSID in 5 to 10 minutes based on ambient temperature (>50°F: 5 minutes; >45°F: 6 minutes; >40°F: 7 minutes; >35°F: 8 minutes; >30°F: 9 minutes; >=30°F: 10 minutes). A 30 second safety bypass below 50 Hertz is employed during rampdown so compressors being ramped down to 5 Hertz to add an additional compressor do not trip on a nuisance low oil differential fault. | Controlled ramped shutdown. Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 218 |
| SYS X YYYYYYYY HIGH DISCHARGE TEMP | Protects the motor and compressor from overheating. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | Discharge Temperature rises above 250°F. The system is also inhibited from starting if the discharge temperature is above 200°F. | Controlled ramped shutdown. Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 218 |
| SYS X YYYYYYYY HIGH OIL TEMP | Protects the compressor from insufficient lubrication. YYYYYYY indicates a "FAULT" condition (restarts when the fault clears) or "LOCKOUT". | Oil temperature rises above 225°F. The system is inhibited from starting if the oil temperature is above 175°F. | Controlled ramped shutdown. Restart when the fault clears; on lockout, will not restart until the operator clears the fault using the keypad. | 219 |
| SYS X YYYYYYYY LOW SUCTION SUPERHEAT | Helps protect the compressor from liquid floodback due to low suction superheat. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | Ignored for the first 30 seconds of compressor operation. Faults when any one of the following occur: after the first 30 seconds of run time, if the suction superheat falls below 2.0°F, the discharge superheat is < 15°F, and the run time is < 5 minutes, the superheat safety is ignored for the next 30 seconds, then the superheat cutout is set to 0°F and linearly ramped up to 2.0°F over the next 60 seconds (fault if the suction superheat falls below the ramped cutout during these 60 seconds); or suction superheat < 2°F and discharge superheat < 15°F for 10 seconds with run time = or > 5 minutes; or suction superheat < 0.5°F and discharge superheat > 15°F for 60 seconds with run time = or > 5 minutes; or suction superheat < 5°F for 10 minutes. | Controlled ramped shutdown. Restart after the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault. | 219 |
| SYS X YYYYYYYY LOW DISCHARGE SUPERHEAT | Helps protect the compressor primarily from liquid floodback through the economizer line due to a high flash tank level; also provides protection from liquid floodback through the suction line in conjunction with the low superheat safety. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | Ignored for the first 5 minutes of compressor operation. After the first 5 minutes of run time, if the discharge superheat falls below 10.0°F for 5 minutes, the system faults. | Controlled ramped shutdown. Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 219 |
| SYS X YYYYYYYY SENSOR FAILURE: ZZZZZZZZZZZZ | Prevents the system from running when a critical sensor (transducer, level sensor, or motor winding temp sensor) is not functioning properly and reading out of range. ZZZZZZZZZZZZ indicates the failed sensor: SUCT PRESS, OIL PRESS, DSCH PRESS, LEVEL SENSOR, or MOTOR TEMP X. YYYYYYY indicates a "FAULT" condition (restarts when the fault clears) or "LOCKOUT" after 3 faults. | Checked at start-up and will prevent the system from running if one of the sensors has failed; also faults and shuts down a system while in operation if a safety threshold is exceeded or a sensor reads out of range (high or low). Start inhibit sensor thresholds: suction transducer 0.3–4.7 VDC; oil transducer 0.3–4.7 VDC; discharge transducer 0.3–4.7 VDC; level sensor 3.0–21.0 mA; motor temp. sensor 0–240°F. | At start-up the system is prevented from running; in operation the system faults and shuts down. Restart when the fault clears; on lockout (after 3 faults), will not restart until the operator clears the fault using the keypad. The Unit Setup Mode allows a specific motor temperature sensor to be ignored if it fails. | 220 |
| SYS X YYYYYYYY HIGH MOTOR TEMP | Prevents a compressor from running when its motor temperature is too high. YYYYYYY indicates a "FAULT" condition (restarts when the fault clears) or "LOCKOUT". | Any compressor motor temperature sensor rises above 250°F. The system is inhibited from starting if its motor temperature sensors indicate temperatures above 240°F. If any single temperature sensor is being ignored under the Unit Set-up Mode, that sensor is not utilized when evaluating motor temperature. | Fault and shutdown. Restart when the fault clears; on lockout, will not restart until the operator clears the fault using the keypad. | 220 |
| SYS X YYYYYYYY HIGH FLASH TANK LEVEL | Prevents the system from running when the liquid level in the flash tank is too high. YYYYYYY indicates a "FAULT" condition or "LOCKOUT". | The safety is ignored for the first 15 seconds of system operation. A fault occurs if the tank level is greater than 85% for 10 seconds. | Restart when the 120 second anti-recycle timer times out; on lockout, will not restart until the operator clears the fault using the keypad. | 221 |
| SYS X YYYYYYYY CONTROL VOLTAGE | Alerts the operator that the 115V AC Control voltage to one of the systems is missing. YYYYYYY indicates a "FAULT" condition (restarts when the fault clears). | The 115V AC Control voltage to one of the systems is missing; this could be due to a system fuse that has been removed or is blown. The affected system faults and shuts down immediately when the 115V AC supply is lost. The safety will not shut down a system if the Unit Switch is OFF (which electrically removes the 115V AC to all systems); it is only used to indicate a situation where a single system is missing the 115V AC. | The safety will not cause a lockout; the system fault resets when power is returned. | 221 |
