Function : To set over voltage limit
To change the OV Parameter
parameter, press the set key.
Use UP/DOWN keys to set desired value.

Fact. Set
Example :
If this parameter is set to

240V it will show OV fault on display
and Compressor Relay will be off.
Parameter

Function : To set time delay for
voltage sensing.
To change the V1 Parameter
parameter, press the set key.
Use UP/DOWN keys to set desired value.

Fact. Set
Example :
If V1 parameter is 5, then if
voltage fault condition occures and
stays continuously for 5 sec then only
fault is valid.
UL
Parameter
16
Function : To set Under current limit.
To change the UL Parameter
parameter, press the set key.
Use UP/DOWN keys to set desired value.

Fact. Set
This parameter used to switch off the
compressor incase it draws lower
current than the set current.
V0
Parameter

Function : To set voltage differential.
To change the V0 Parameter
parameter, press the set key.
Use UP/DOWN keys to set desired value.

Fact. Set
Example :
If this parameter is set to 5V
then for OV fault when voltage is grater
than OV-5 then only this fault is cleared.
For UV fault then when the voltage is
greater than UV+5 then only UV fault
will be cleared.

Example :
If you set this parameter to
20min, once the power is switch on, the
alarm for Ht/Lt will not activate for 20
minutes after the power is switched on.
This is most useful to avoid the nuisance
alarms when the ambient are high when
machine is switched on after long time.
