7.9 Auto-Reset
The MCD 500 can be programmed to automatically reset
certain trips, which can help minimise operating
downtime. Trips are divided into three categories for auto-
reset, depending on the risk to the soft starter:
Group
A
Current Imbalance
Phase Loss
Power Loss
Mains Frequency
B
Undercurrent
Instantaneous Overcurrent
Input A Trip
C
Motor Overload
Motor Thermistor
Starter Overtemperature
Table 7.7
Other trips cannot be automatically reset.
This function is ideal for remote installations using 2-wire
control in Auto On mode. If the 2-wire start signal is
present after an auto-reset, the MCD 500 will restart.
