Troubleshooting an SPS

Overview

This section contains explanations of fault messages associated with the SPS that may

 

appear on the 4100U-S1 display. Heading text in the left margin shows the error message,

 

while the paragraph next to it describes the likely cause of the message.

“IDNet Power Monitor Trouble”

“Extra Device”

There is no output voltage from the power supply. Refer to Chapters 2 and 5 for information on power supplies.

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.

“Class A Trouble”

“Earth Fault Search”

There is an open circuit on the IDNet channel. A hardware reset of the system is required to reset the fault.

Comes up during the Earth Fault Search diagnostic function. 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. SPS circuits (IDNet, NAC, and aux power) are searched. System alarm and trouble processing is suspended during the search.

“Short Circuit”

“Channel Fail”

Appears when a short circuit is detected on the IDNet channel. This status clears automatically when the short circuit is removed.

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.

“No Answer/ Bad Answer”

“Output Abnormal”

Occurs when the 4100U-S1 is put into a diagnostic mode and finds a device not responding, or responding unreliably.

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.
