Function: To activate/deactivate Compressor2 LP Fault
Digital Input.
If this parameter is set to,
(0)
= Digital input is disabled.
(1)
= Digital input is open connection (0V)
will be a fault.
(2)
= Digital input is close connection (230V)
will be a fault.

Function: Compressor2 LP Fault Digital Input Sensing
Delay. (Surge)
Example: If LS2 is set to 5 seconds, once the Compressor2
is ON, controller will ignore the LP Fault for 5 Seconds.

Function: Compressor2 LP Fault Digital Input Sensing
Delay. (Normal)
Example: If Ln2 is set to 5 seconds, once the Compressor2
is ON, if the LP Input is unhealthy for continuous 5
seconds, controller will trip the Compressor on LP Fault.

Function: To set reset mode for Compressor2 output, on
Compressor2 LP Fault Digital Input.
If this parameter is set to,
(0)
= Auto Reset Option for LP Fault.
(1)
= Manual Reset Option for LP Fault after
L42 retrials in 1 Hour.
Example:
If user has set the parameter to following:
= LP Fault will get cleared automatically once
the Input becomes healthy.
= If this parameter is set to and L42
parameter is set to 5 then if the Compressor
gets tripped on LP fault for 5 times in 1 hour,
