Channel Fail

No Answer/

Bad Answer

Output Abnormal

This section contains explanations of fault messages that may appear on the 4100U display when using the SPS. Heading text in the left margin shows the error message, while the paragraph next to it describes the likely cause of the message.

There is no output voltage from the power supply. Refer to Chapters 2 and 6 for information on power supplies.

Appears if one or more extra devices (i.e., devices that have not been configured for the IDNet channel) are one the system. Only one message appears, regardless of the number of extra devices found.

There is an open on the IDNet channel. A hardware reset 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 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. System alarm and trouble processing is suspended during the search.

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

Appears when each device on the IDNet channel has been configured, and when none of the devices are communicating on the channel. This message does not appear if there are no configured devices on the IDNet channel.

Occurs when the 4100 is put into a diagnostic mode and finds a device not responding, or responding unreliably. Refer to the 4100U PC Programmer Programming Manual (574- 849) for information on how to perform this diagnostic.

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.
