Elstat ems75 Sub-Zero User Manual

Range -30 to 5ºC (-22 to 41ºF)
Global default
-6ºC (21ºF)
ems75sz: -15ºC (5ºF)
9.15 Defrost termination temperature (dtd)
The table below details the defrost temperature duration (dtd) parameter.
Display
Description
Defines the temperature to end the defrost cycle.
Ending defrost cycles on temperature minimizes the duration of defrost
cycles.
The temperature is measured as follows:
l
OFC and sub-zero coolers: the temperature is measured on the evaporator
sensor.
l
GDC coolers: the temperature is measured on the appliance sensor.
Considerations
l
Must be set above the set point (S P) plus differential (dIF)temperature.
l
Must be set below IPd.
l If icing up occurs, review the values of the defrost parameters.
Range
1 to 30ºC (33 to 86ºF)
ems75sz: -5 to 22ºC (23 to 71ºF)
Global default
9.0ºC (48ºF) - OFC firmware
10.0°C (50°F) - Firmware excluding OFC and SZ
15.0ºC (59ºF) - SZ firmware
9.16 Compressor rest time (rt)
The table below details the compressor rest time (rt) parameter.
Display
Description
Defines the minimum time between compressor cycles.
The compressor rest time ensures that the pressures in the refrigeration sys-
tem have time to equalize during compressor off-cycles.
The compressor rest time (rt) helps to avoid the following:
l passing peak current through the windings of the compressor motor
l switching off the system on the thermal overload protection
l short cycling of the system.
Considerations
If set too low, the compressor rest time may cycle on the set point
(SP) and differential (dIF) temperatures or the saving set point
(SSP) and saving differential (Sd) temperatures.
Range 1 to 30 minutes
Global default 3 minutes
