SIMPLEX Fault Assistance Guide RevA

10. Charger high/low/normal Raw value = high/low/normal
This message indicates the battery charger voltage is high or low. When this fault is
viewed in the system fault recall, the display will show the current state of the
charger as high, low, or normal, which may be useful for adjusting the charger
potentiometer. A charger low condition will not produce a system fault until 30
minutes after any battery test, but will still appear in a system fault recall during this
time. During a battery test a charger low condition (for the raw value) will be
displayed in a system fault recall as the charger is inhibited, but this is not a system
fault.
11. Fuse blown
Check for a blown fuse, and replace with a fuse of the same amperage rating
12. Clock chip RAM fault
Clock chip RAM is used to store all the isolate data (zone and relay isolate status,
etc) plus temporary "board present" assignments. The isolate data and board
present data is read from clock chip RAM at startup and this fault means the clock
chip RAM has not saved the data correctly and will probably not be read correctly at
startup. Try isolating and de-isolating something (e.g. bells) to get the controller to
retry writing/reading this RAM.
13. EEPROM write fail
This fault will occur if a failure occurs when writing to EEPROM database memory
during program mode.
14. All MAF zones isolated
This fault will occur if all zones (mapped to MAF) are isolated. This can be inhibited
with an option in programming, but doing so contravenes AS1603.4.
15. Supply failed
This fault means that both mains have failed and the battery voltage has fallen to 21
volts or below. The standby relay is de-energised and all processing of circuit inputs
stops.
16. Output logic exec error nn
An error has occurred with output logic execution. The error number nn has the
following meaning:
