enter the resistance that the thermistor must rise above before a thermistor trip or

•
HOT RESISTANCE
: For a PTC thermistor, enter the resistance that the thermistor must
rise above before a thermistor trip or alarm will occur. For a NTC thermistor, enter the
resistance that the thermistor must drop below before a thermistor trip or alarm will
occur.
•
THERMISTOR TRIP
: When a thermistor is used, it can be selected for an alarm or trip or
both. Choose “ENABLE” to allow thermistor trips to occur.
•

Fault Mode
PATH: S1 CONFIGURATION
ÖØ
FAULT MODE
The fault mode settings are programmed as follows:
•
INTERNAL FAULT TRIP
: An internal fault during self-checking will cause an alarm.
Since operation may be erratic depending on the fault condition, it may be desirable
to trip the motor by setting this setpoint to “ENABLE”. The MM3 Motor Manager 3
continues to run the motor with an internal fault present if set to “DISABLE”.
•
SERIAL COMMS FAILURE TRIP
: If the serial communications link is used to control a
process with several motors working together, it may be desirable to shut down the
motor if communication control is lost. When no activity occurs on the
communications port for 5 to 25 seconds, it will trip if this feature is enabled.
•
SERIAL COMMS FAILURE ALARM
: Sets an alarm when the serial communication link is
interrupted.
•
CHANGE COMMAND MODE ON ALARM
: Allows the command mode to automatically
switch from AUTO to MANUAL when the
SERIAL COMMS FAILURE ALARM
is active. If the
motor was running when the alarm occurred it will be stopped and will restart based
on manual start inputs only. When serial communication is restored the MM3 Motor
Manager 3 will remain in MANUAL command mode.
