Other Parameters - Emerson Dixell IEV22D Manual

•
Et48 = MOP alarm signal delay
•
Et49 = High superheating alarm signal delay
•
Et50 = Low superheating alarm signal delay
•
Et51 = PID proportional constant in defrost mode
During operation in defrost mode, the valve's adjustment is carried out in accordance with
the cooling mode, except for the fact that the value of the PID proportional constant, which is
the dedicated Et51 parameter
•
Et52 = Number of aperture steps of valve 1 before the adjustment in defrost mode
At the time of entry in defrost mode, the valve sets itself to the number of steps set under
parameter Et52 for the Et53 time
•
Et53 = Time for which the steps of valve 1 are maintained before the adjustment for defrost
•
Et54 = Number of aperture steps of valve 2 before the adjustment in defrost mode
At the time of entry in defrost mode, the valve sets itself to the number of steps set under
parameter Et54 for the Et55 time
•
Et55 = Time for which the steps of valve 2 are maintained before the adjustment for defrost
•
Et56 = Increase/decrease opening percentage when the PID is saturated in cooling mode
•
Et57 = Increase/decrease opening percentage when the PID is saturated in heating mode
•
Et58 = Increase/decrease opening percentage when the PID is saturated in defrost

8.7 Other parameters

•
Ec46 = Communication address of the Modbus protocol
•
Ec47 = LAN communication protocol address
If the driver is used in LAN configuration with a Ichill 200 EVO, the communication address
must be assigned both to the Ichill and the IEV driver (the address is the same both in Ichill
and IEV)
•
Ec48 = Map code
Read-only parameter that identifies the parameter map code
•
Ec49 = Firmware version
Read-only parameter that identifies the firmware version
•
Pr2 = Access password Pr2 and Alarm Log reset
