Danfoss ERC 112D VSC User Manual

ERC menu code Description
"tHE Thermostat settings
"SEt"
Min. -100.0°C
Max. 200.0°C
Default 2.0°C
Set point
This parameter defines the desired temperature (set point).
In standard operation the set point is changed by simply pressing the
"temperature up/down" buttons on ERC 112D VSC; for laboratory and
assembly line you may opt for software controlled set point adjustment
(speed improvement)
"SPr"
Min. 0.0
Max. 1.0
Default 0.5
Current set point adjustment value diF * SPr
The default value is set to 0.5 and the parameter is hidden by default.
"Spr" defines the position of the set point in relation to cut-in and cut-out.
"Spr=0,5" sets the set point mid between cut-in and cut-out.
"Spr=0" sets the set point at the cutout. "Spr=1" sets the set point at cut-in.
"diF"
Min. 0.0 K
Max. 20.0 K
Default 2.0 K
Thermostat differential
This defines the difference between the cut-out and the cut-in.
The desired temperature is determined by "SPr" and "diF".
"HSE"
Min. -100.0°C
Max. 200.0°C
Default 50.0°C
Upper limit of thermostat set point
Define the temperature range limit of the controller.
Once set, the desired temperatue (set point) can not go above "HSE" or
below "LSE".
"LSE"
Min. -100.0°C
Max. 200°C
Default -35.0°C
Lower limit of thermostat set point
Define the temperature range limit of the controller.
Once set, the desired temperatue (set point) can not go below "LSE".
"iCi"
Min. no
Max. yes
Default no
Initial cut in
This parameter is to set the refrigeration system action when cab air temperature is between cut-in and cut-out at power up.
yES : Switch on the refrigeration system immediately.
no: Keep the refrigeration system off until cab air temp reaches cut in temperature.
FAn Fan settings
"FCt"
Default FAo
Fan control method
"FAo": fan always on
"SEt": fan follow compressor by manual settings. (FoC and FSC needs to be set accordingly)
"Aut": automatical fan control
"Fod"
Min. 0 s
Max. 240 s
Default 0 s
Fan ON Delay/Fod
Fod defines the fan delay (in seconds) after a compressor cut-in.
Fan Stop Delay/FSd
"FSd" defines the fan delay after a compressor cut-out.
If both "Fod" and "FSd" are set to zero then the fan runs whenever the
compressor runs.
"FSd"
Min. 0 s
Max. 240 s
Default 0 s
"FoC"
Min. 0 s
Max. 960 s
Default 0 s
Fan ON Cycle/FoC
Fan Stop Cycle/FSC
When the compressor is OFF, and "FoC" or "FSC" are not zero, the fan
runs in cycles according to "FoC" and "FSC".
Example: "FoC=120" [sec] and "FSC=120" [sec] means that the fan runs
for half the time when the compressor is OFF. When the compressor is
on, the fan is always ON (according to "FAo" and "Fod").
"FSC"
Min. 0 s
Max. 960 s
Default 0 s
"FSt"
Min. 0 s
Max. 960 s
Default 10 s
Fan Minimum Stop time
Minimum stop time for fan protection.
"FdC"
Min. -10.0 K
Max. 10.0 K
Default 0.0 K
Fan Δt cut in
(This parameter is only applicable with Automatic fan control "Aut" mode.)
Delta T for fan to cut in which the temperature offset comparing with
thermostat cut in temperature.
