40 ACT2000 USER GUIDE
FAULT Alarm
The configuration of faults assigned to the FAULT alarm is programmable
in the most recent generation
of the ACT2000 (factory-configurable
only). See Table 3-1 for the default configuration of faults assigned to
the FAULT alarm.
See Table 3-3 for a list of fault conditions represented by the FAULT
alarm in earlier generations
of the ACT2000.
OVERTEMP Alarm
The configuration of faults assigned to the OVERTEMP alarm is
programmable in the most recent generation
of the ACT2000 (factory-
configurable only). In the default configuration, the Motor Over Temp fault
is the only fault assigned to the OVERTEMP alarm. If the ACT2000
detects that the temperature in two or more of the motor windings is
135°C or higher, the OVERTEMP alarm circuit opens. See Table 3-2 for
details about the default configuration
of the OVERTEMP alarm.
See Table 3-4 for a list of Over Temp conditions represented by the
OVERTEMP alarm in earlier generations
of the ACT2000.
Fault File
The ACT2000 firmware also captures the fault data in the EEPROM. If
the ACT2000 is operational, a fault file can be downloaded using ActWiz
software via the RS232 interface. The fault file will provide fault
information and possible causes. The ACT2000 must be in the Power Up
/ Set Up state to download the fault file. See Section 3.8 for details about
the Power Up / Set Up state. Contact Precision Engine Controls
Corporation to request ActWiz software.
Toggling the RESET command will clear the fault alarm, but it does NOT
clear the fault file.
See Section 5: Troubleshooting for a more detailed list of fault causes.
Note: The fault file only records the programmable faults that have
been enabled .
