LP SENSING DLY
HP / AFT RST
EXAMPLE:
If this parameter is set at 30
seconds, the system will ignore low
pressure alarm for 30 sec from
compressor on.In this manner, a false
alarm can be avoided due to low
pressure at compressor start up.
Use UP/DOWN keys to set desired
range.
Auto= it sets the HP- AFT faults for auto
reset.
Use UP/DOWN keys to set desired
range.
Manual= it sets the HP- AFT faults for
manual reset
