Auxiliary Trip Circuit

In normal operation the ASTAT XL is controlled via a remote two-wire signal (terminals 56, 57).
Input A (terminals 53, 55) is connected to an external trip circuit (such as a low pressure alarm switch
for a pumping system). When the external circuit activates, the soft starter trips, which stops the
motor.

Parameter settings:
• Parameter 6D Input A Function
• Select 'Input Trip (N/O)'. Assigns the Input A to Auxiliary Trip (N/O) function.
• Parameter 6E Input A Name
• Select a name, eg Low Pressure. Assigns a name to Input A.
• Parameter 4E Input A Trip
• Set as required. For example, 'Run Only' limits the input trip to when the soft starter is running
only.
• Parameter 5E Input A Trip Delay
• Set as required. Sets a delay between the input activating and the soft starter tripping.
• Parameter 5F Input A Initial Delay
• Set at around 120 seconds. Limits operation of the input trip to 120 seconds after the start
signal. This allows time for pressure to build up in the piping before the low pressure input
becomes active.
