input terminals and trips if the actual sequence does not match the selected
option.
4C – Undercurrent
Range:
0% - 100%
Default:
20%
Description:
Sets the trip point for undercurrent protection, as a percentage of motor full
load current. Set to a level between the motor's normal working range and
the motor's magnetising (no load) current (typically 25% to 35% of full load
current). A setting of 0% disables undercurrent protection.
4D – Instantaneous Overcurrent
Range:
80% - 600% FLC
Default:
400%
Description:
Sets the trip point for instantaneous overcurrent protection, as a percentage
of motor full load current.
4E – Input A Trip
Options:
Always Active (default)
A trip can occur at any time when the soft starter is
receiving power.
Operating Only
A trip can occur while the soft starter is running,
stopping or starting.
Run Only
A trip can only occur while the soft starter is
running.
Description:
Selects when an input trip can occur.
4F – Motor Temperature Check
Options:
Do Not Check (default)
Check
Description:
Selects whether the ASTAT XL 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.
4G – Frequency Check
Options:
Do Not Check
Start Only
Start/Run (default)
Run Only
Description:
Determines when and if the starter will monitor for a frequency trip.
4H – Frequency Variation
Options:
± 2 Hz
± 5 Hz (default)
± 10 Hz
± 15 Hz
Description:
Selects the soft starter's tolerance for frequency variation.

5 Protection Delays
5A – Restart Delay
Range:
00:01 - 60:00 (minutes:seconds)
Default:
10 seconds
Description:
The ASTAT XL 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.
5B – Current Imbalance Delay
Range:
0:00 - 4:00 (minutes:seconds)
Default:
3 seconds
