OL
Parameter
17
Function : To set Over current limit.
To change the OL parameter,
press the set key.
Use UP/DOWN keys to set desired
value.
This parameter used to switch off the
compressor incase it draws higher
current than the set current.
Example :
If this parameter is set at
10.0A, the controller will trip compressor
if it draws more than 10.0A.Controller
will restart the compressor after the set
time delay. If after 3 retries within 1hour,
current drawn is still more than 10.0A,
the controller will trip the compressor on
fault and activate the respective alarm
relay. Also display will flash “OL”.

Example :
Use UP/DOWN keys to set desired value.
DIS = HP sensing is disabled
Setting this parameter to disable will
ignore HP fault for compressor. If this
parameter is set to Enable then controller
will detect HP trip.
To change the D0 parameter,

Parameter
18
Function: To set Current sensing delay.
Use UP/DOWN keys to set desired

Example :
If C2 parameter is 1 Sec
then, any current fault will be valid only
when it exsists for more than 1 sec.
