Troubleshooting an SPS
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| “IDNet Power Monitor Trouble” | No output voltage from the power supply. | There is no output voltage from the power supply. | Refer to Chapters 2 and 5 for information on power supplies. | 66 |
| “Extra Device” | One or more extra devices are on the system. | One or more extra devices, i.e., devices that have not been configured on the IDNet channel, are on the system. Only one message appears, regardless of the number of extra devices found. | 66 | |
| “Class A Trouble” | Open circuit on the IDNet channel. | There is an open circuit on the IDNet channel. | A hardware reset of the system is required to reset the fault. | 66 |
| “Earth Fault Search” | Displayed during the Earth Fault Search diagnostic function; system alarm and trouble processing is suspended during the search. | Comes up during the Earth Fault Search diagnostic function. SPS circuits (IDNet, NAC, and aux power) are searched. | Once the search is initiated, the front panel display indicates how far the search process has progressed (10%, 25%… 75%), and then shows the results of the search. The result either identifies the offending circuit or indicates that the earth fault could not be found. | 66 |
| “Short Circuit” | Short circuit detected on the IDNet channel. | Appears when a short circuit is detected on the IDNet channel. | This status clears automatically when the short circuit is removed. | 66 |
| “Channel Fail” | Devices are configured on the IDNet channel but none are communicating. | Appears when at least one device on the IDNet channel has been configured, but no devices are communicating on the channel. This message does not appear if there are no configured devices on the IDNet channel. | 66 | |
| “No Answer/ Bad Answer” | Device not responding, or responding unreliably. | Occurs when the 4100U-S1 is put into a diagnostic mode and finds a device not responding, or responding unreliably. | 66 | |
| “Output Abnormal” | 24 V not present on TrueAlarm devices; TrueAlarm sensor bases with relay driver outputs not properly supervised; or isolator devices in isolation mode. | Occurs when 24 V is not present on TrueAlarm devices or when TrueAlarm sensor bases with relay driver outputs are not properly supervised or when isolator devices are in isolation mode. | 66 |
Using T-Gen 50 with 4100U-S1
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| “SPS Over Current” | Fault produced in the system. | T-GEN 50 draws a large in-rush current when it is first turned on (the T-GEN 50 should not be powered from a NAC output). | Can only be cleared by pressing the 4100U System Reset button. The manual states this is not acceptable operation. | 79 |
The IDNet Card – LEDs
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| LED1 – On steady | The IDNet card is not communicating with the 4100U CPU (normally off). | 95 | ||
| LED2 – Steady on | Channel failure, i.e. communication problems with configured devices. Indicates a problem with the IDNet lines (normally off). | 95 | ||
| LED2 – One repetitive blink | Line short. | 95 | ||
| LED2 – Two repetitive blinks | Class A failure or an open line. | 95 |
Troubleshooting on IDNet
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| “IDNet Power Monitor Trouble” | No output voltage from the IDNet power supply. | There is no output voltage from the IDNet power supply. | Replace the IDNet card. | 101 |
| “Extra Device” | Extra devices found on the channel, or a device at an incorrect address. | Appears if one or more extra devices (i.e., devices that have not been configured for the IDNet channel) are found on the channel, or if a device is at an incorrect address. Only one message appears, regardless of the number of extra devices found. | Viewing the trouble log will reveal the extra device address. | 101 |
| “Class A Trouble” | Open on the IDNet channel. | There is an open on the IDNet channel. | After fixing the wiring fault, a hardware reset is required to reset the trouble. | 101 |
| “Earth Fault Search” | Displayed while the IDNet card is searching for earth faults on the IDNet line; the IDNet card cannot show any alarms or other statuses while this message is displayed. | Appears while the IDNet card is searching for earth faults on the IDNet line. | 101 | |
| Short Circuit | Short detected on the IDNet channel. | Appears when a short is detected on the IDNet channel. | This status clears automatically when the short circuit is removed. | 101 |
| “Channel Fail” | Devices have been configured, but none of the devices are communicating on the channel. | Appears when devices have been configured, but none of the devices are communicating on the channel. This message does not appear if there are no configured devices on the IDNet channel. | 101 | |
| “No Answer” | A device is missing. | Appears when a device is missing. | 101 | |
| “Bad Answer” | Faulty device or noisy communications channel. | Appears when there is a faulty device or a noisy communications channel. | 101 | |
| “Output Abnormal” | 24 V not present on TrueAlarm devices; TrueAlarm sensor bases with relay driver outputs not properly supervised; or isolator devices in isolation mode. | Occurs during any of these conditions: 24 V is not present on TrueAlarm devices; TrueAlarm sensor bases with relay driver outputs are not properly supervised; isolator devices are in isolation mode. | 101 |

|---|---|---|---|---|
| CARD 17, ANALOG AUDIO CONTROLLER AUDIO RISER 1 EARTH FAULT | Non-point fault: a ground that cannot be traced to an addressable point (for example, a shield or an audio riser); in this example the earth fault is not occurring at the audio controller but somewhere in the riser. | Non-point faults can be displayed for each of the following items: Channel Output (IDNet Card; MAPNET Interface Card); RUI Channel (Master Controller Card) (not used in 4100U-S1); Channel 1 to 3 (TrueAlert Power Supply) (not used in 4100U-S1). | Once you have been directed to an earth fault and corrected it, it is recommended that you restart the system (warm- or cold-start). | 122 |
| CARD 003, FLEX 50 AMPLIFIER 3-10-0 EARTH FAULT | Point fault: an earth fault at a specific addressable point (in this example card address 3, point number 10, sub-point number 0, not used). Point faults can be found at any point in the system that connects to field wiring. | Earth fault at a specific addressable point. | Once you have been directed to an earth fault and corrected it, it is recommended that you restart the system (warm- or cold-start). | 122 |
| CARD 2, IDNET CARD (250 POINTS) M1, EARTH FAULT SEARCH FAULT CLEAR FAIL | Fault not cleared: an IDNet channel that has been isolated for fault detection still has the earth fault. | Once you have been directed to an earth fault and corrected it, it is recommended that you restart the system (warm- or cold-start). | 122 | |
| CARD 2, IDNET CARD (250 POINTS) M1, CHANNEL OUTPUT EARTH FAULT | Fault between the IDNet channel output and the first isolator on the line. | Once you have been directed to an earth fault and corrected it, it is recommended that you restart the system (warm- or cold-start). | 122 | |
| CARD 2, IDNET CARD (250 POINTS) M1-3, IDNET ISOLATOR EARTH FAULT | IDNet isolator fault: a fault detected after the IDNet isolator was turned on. | 123 | ||
| FAULT NOT FOUND / FAULT CLEAR FAIL | The search could not locate the fault, but it acknowledges that a fault exists. FAULT NOT FOUND displays for a Location Earth Fault Search; FAULT CLEAR FAIL for an IDNet Channel Earth Fault Search. | Possibilities: there are one or more internal wiring earth(s) in the system; there are system defects (hardware or software, such as a failed isolation circuit); an intermittent earth exists in the system (it occurs inconsistently and is therefore difficult to track via diagnostics); the cable to the service port may be grounded due to the remote PC's 3-pin plug (run the laptop on batteries only, or use an isolating transformer to the PC); the fault is on an auxiliary output that was excluded from the search. | The problem may have to be found manually and then corrected in some of the above scenarios. | 123 |
