Voltage Protection function
This feature protects the compressor if the line voltage goes beyond the operating
range.
Minimum Cut-in Voltage 110 V (230
V)
The lowest voltage at which the compressor is allowed to cut in.
Minimum Cut out Voltage 110 V
(230 V)
If the voltage goes below this value when the compressor is running, the compres-
sor will be switched o. It is meant to avoid sudden switching on and o of com-
pressor due to voltage uctuations. This cut-o voltage will override compressor
minimum run time.
Maximum cut out Voltage 110V
(230V)
When the compressor is running, it will be switched OFF if the voltage exceeds this
value. If the compressor is already stopped, it will remain switched o.
Condenser Alarm Limit (°C)
It sets the condenser temperature at which an alarm will be generated
Condenser Block Limit (°C)
It sets the compressor switched o due to high condenser temperature.
It sets the compressor to switch on again after it has been switched o due to high
condenser temperature, respecting minimum compressor stop time.
Control sensor error handling type
Method to control the cooling cycle in case of cabinet air sensor error:
“no” : no sensor error handling
“SEt” : follow congured error run and stop time.
“Aut” : control automatically based on past cycles time.
Cooling cycle ON time in case of cabinet sensor error (active only if EHd=Set)
Cooling cycle OFF time in case of cabinet sensor error (active only if EHd=Set)
It enhances the relay life and avoids relay sparks during relay ON and OFF. If “Yes” is
selected, the relays will be switched ON and OFF when the line-voltage is closeer to
zero.
Test Mode
Table 12: Test Mode
Normal mode - Normal operation mode of the controller
Manual mode- In this mode, output relays can be switched ON and OFF irrespective
of temperature conditions.
