Troubleshooting an SPS
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| IDNet Power Monitor Trouble | There is no output voltage from the power supply. | 80 | ||
| Extra Device | One or more extra devices are present on the loop, i.e. devices that have not been configured for the IDNet channel. Only one message appears, regardless of the number of extra devices found. | Extra devices present on the loop that have not been configured for the IDNet channel. | 80 | |
| Class A Trouble | There is an open circuit fault detected on the IDNet channel. | A hardware reset is required to reset the fault indication. | 80 | |
| Earth Fault Search | Displayed during the Earth Fault Search diagnostic function. The front panel display indicates how far along 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. SPS circuits (IDNet, NAC, and aux power) are searched. | Earth Fault Search diagnostic function initiated. | System alarm and fault processing is suspended during the search. | 80 |
| Short Circuit | A short circuit fault is detected on the IDNet channel. | Short circuit on the IDNet channel. | This status clears automatically when the short circuit is removed. | 80 |
| Channel Fail | Each device on the IDNet channel has been configured, but none of the configured devices are communicating on the channel. This message does not appear if there are no configured devices on the IDNet channel. | None of the configured devices are communicating on the channel. | 80 | |
| No Answer/Bad Answer | The 4100ES is put into a diagnostic mode and finds a device not responding, or responding unreliably. | Device not responding, or responding unreliably. | Refer to the 4100 Fault Finding Guide (LT0565) for information on how to perform this diagnostic. | 80 |
| Output Abnormal | Abnormal output condition at field devices. | 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. | 80 | |
| Mains fail fault | AC mains supply failure. | Generated when the DC voltage drops below 20.3 V (nominally 204 Vac). The AC input is supervised. | 76 | |
| SPS Over Current | SPS over current fault in the system. | T-GEN 50 draws a large in-rush current when it is first turned on (e.g. when powered from a NAC output). | Can only be cleared by pressing the 4100ES System Reset button. The T-GEN 50 should not be powered from a NAC output. | 91 |
Troubleshooting IDNet Faults
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| IDNet Power Monitor Trouble | There is no output voltage from the IDNet power supply. | Replace the IDNet card. | 107 | |
| Extra Device | One or more extra devices (i.e. devices that have not been configured for the IDNet channel) are found on the ID-Net loops, or a device is at an incorrect address. Only one message appears, regardless of the number of extra devices found. | Extra devices on the IDNet loops, or a device at an incorrect address. | Viewing the fault log will reveal the extra device address. | 107 |
| Class A Trouble | There is an open circuit on the IDNet channel. | After fixing the wiring fault, a hardware reset is required to reset the trouble. | 107 | |
| Earth Fault Search | The IDNet card is searching for earth faults on the IDNet line. | Earth fault search active on the IDNet line. | When this message is displayed, the IDNet card cannot show any alarms or other statuses. | 107 |
| Short Circuit | A short circuit is detected on the IDNet channel. | This status clears automatically when the short circuit is removed. | 107 | |
| Channel Fail | 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. | None of the configured devices are communicating on the channel. | 107 | |
| No Answer | A device is missing. | Device missing. | 107 | |
| Bad Answer | A faulty device or a noisy communications channel. | Faulty device or noisy communications channel. | 107 | |
| Output Abnormal | Abnormal output condition. | 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. | 107 |
Using Install Mode
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Install Mode Active | Single fault indication shown while any device is in the Install Mode list. Devices in the Install Mode list will not produce fault indications, even if they are missing or faulty — all the individual device faults are hidden behind a single Install Mode Active fault. | One or more internal modules or external devices have been added to the Install Mode list. | When the system is fully commissioned, the Install Mode list should be empty. | 109 |
Brigade Interfaces
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| SPS CPU Fault | Hardware fault signal; the Fault (Trouble) relay on the Alarm Relay Card is link connected to this signal. | 122 |
Search Results
| Code / display | Meaning | Cause | Action | Page |
|---|---|---|---|---|
| Non-point fault | A ground that cannot be traced to an addressable point (for example, a shield). Non-point faults can be displayed for each of the following items: Channel Output (IDNet Card; MAPNET Interface Card); RUI Channel (Master Controller Card). | Once you have been directed to an earth ground fault and corrected it, it is recommended that you restart the system (warm- or cold-start). | 139 | |
| Point fault | A ground at a specific addressable point. Point faults can be found at any point in the system that connects to field wiring. | Once you have been directed to an earth ground fault and corrected it, it is recommended that you restart the system (warm- or cold-start). | 139 | |
| CARD 2, IDNET CARD (250 POINTS) M1, CHANNEL OUTPUT EARTH FAULT | Earth fault between the IDNet channel output and the first isolator on the line. | 139 | ||
| CARD 2, IDNET CARD (250 POINTS) M1-18, 4009A NAC EARTH FAULT | Earth fault detected on the 4009 IDNet NAC Extender before the repeater connected to that circuit is turned on. | 139 | ||
| CARD 2, IDNET CARD (250 POINTS) M1-18, 4009A REPEATER EARTH FAULT | Earth fault detected after the repeater connected to that circuit is turned on. | 139 | ||
| CARD 2, IDNET CARD (250 POINTS) M1-3, IDNET ISOLATOR EARTH FAULT | Earth fault detected after the IDNet isolator was turned on. | 139 | ||
| 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. | 139 | ||
| FAULT NOT FOUND FAULT CLEAR FAIL | The search could not locate the fault, but it acknowledges that a fault exists. FAULT NOT FOUND is returned for a Location Earth Fault Search; FAULT CLEAR FAIL for an IDNet Channel Earth Fault Search. | One or more internal wiring earth(s) in the system; system defects (hardware or software, such as a failed isolation circuit); an intermittent earth that occurs inconsistently; the cable to the service port may be grounded due to the remote PC's 3-prong plug; the fault is on an auxiliary output that was excluded from the search. | The problem may have to be found manually and then corrected. Once corrected, it is recommended that you restart the system (warm- or cold-start). | 140 |
