Example :
If this parameter is set to
5Amp then controller will trip compressor
on Underload fault incase it is drawing
less than 5 Ampere.
Use UP/DOWN keys to set desired
value.
To change Ct LO reset
parameter, press the set key.
To change Ct HI parameter,
press the set key.

Function : This parameter sets Low
current limit for the compressor below
which it will trip on “Underload” Fault.
Function : This parameter sets High
current limit for the compressor below
which it will trip on “Overload” Fault.
CURRENT RETRIALS
31
Function : No. of retrials before sensing
underload / overload fault in auto mode.
To change Ct retrials
