Description
This feature protects the compressor if the line voltage goes beyond the operating
range.
The lowest voltage at which the compressor is allowed to cut in.
If the voltage goes below this value when the compressor is running, the compres-
sor will be switched off. It is meant to avoid sudden switching on and off of com-
pressor due to voltage fluctuations. This cut-off voltage will override compressor
minimum run time.
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 off.
It sets the condenser temperature at which an alarm will be generated
It sets the compressor switched off due to high condenser temperature.
It sets the compressor to switch on again after it has been switched off due to high
condenser temperature, respecting minimum compressor stop time.
Method to control the cooling cycle in case of cabinet air sensor error:
"no" : no sensor error handling
"SEt" : follow configured 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.
Description
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.
