PROGRAMMING MENU
4M – Restart Delay
Range:
00:01 - 60:00 (minutes:seconds)
Default:
10 seconds
Description:
The EMX3 can be configured to force a delay between the end of a stop and the beginning of the next start.
During the restart delay period, the display shows the time remaining before another start can be attempted.
NOTE
The restart delay is measured from the end of each stop. Changes to the restart delay setting take effect after the next
stop.
4N – Motor Temperature Check
Options:
Do Not Check (default)
Check
Description:
Selects whether the EMX3 will verify the motor has sufficient thermal capacity for a successful start. The soft
starter compares the motor's calculated temperature with the temperature rise from the last motor start and
only operates if the motor is cool enough to start successfully.
4O – Ground Fault Level
Range:
20 mA - 50 A (21 steps)
Default:
100mA
Description:
Sets the trip point for ground fault protection.
4P – Ground Fault Delay
Range:
0:01 - 4:00 (minutes:seconds)
Default:
3 seconds
Description:
Slows the EMX3's response to ground fault variation, avoiding trips due to momentary fluctuations.
NOTE
Ground fault protection is only available if the RTD/PT100 and ground fault protection card is fitted.

5 Auto-Reset Trips
The EMX3 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
Trips
A
Current imbalance
Phase Loss
Power loss
Frequency
B
Undercurrent
Instantaneous overcurrent
Input A trip
Input B trip
C
Motor overload
RTD/PT100 temperature trips
Motor thermistor
Heatsink overtemperature
Other trips cannot be automatically reset.
