Description
Values
Code
Short name
Defrost A
Actual status of output function
0=OFF, 1=ON
u60
u60 Def. relay
Defrost time A
Read the duration of the ongoing defrost or the dura-
tion of the last completed defrost.
u11
u11 Defrost time
Start defrost
Command for starting a defrost
0=OFF, 1=ON
x09
--- Def. Start
Stop defrost
Command for stopping an ongoing defrost cycle
0=OFF, 1=ON
x10
--- Def. Stop
Defrost method
Select method of defrost
0=None, 1=Electrical, 2=Hot gas, 3=Brine, 4=Air/
Offcycle
d01
d01 Def. method
Defrost stop meth-
od
Here you define whether a defrost cycle is to be stop-
ped by time or by a temperature sensor
0=Time, 1=S5 sensor, 2=S4 sensor
d10
d10 DefStopSens.
Defrost stop limit 1
When the selected defrost stop sensor reaches the set
limit, the defrost cycle is terminated
d02
d02 Def.StopTemp
Defrost stop limit 2
Defrost stop temperature limit when thermostat band
2 is in operation.When the selected defrost stop sen-
sor reaches the set limit, the defrost cycle is termina-
ted
d28
d28 DefStopTemp2
Min. defrost time
Minimum duration of a defrost cycle. The defrost cy-
cle will as a minimum run for the set minimum defrost
time once it is started
d24
d24 Min Def Time
Max. defrost time 1 Max. duration of a defrost cycle. The setting is also
used as a safety time if the defrost is stopped on tem-
perature. If the selected defrost stop sensor does not
reach the set defrost stop temperature limit within
the set time, the defrost will be stopped anyway.
d04
d04 Max Def.time
Max. defrost time 2 Max. duration of a defrost cycle when thermostat
band 2 is in operation. The setting is also used as a
safety time if the defrost is stopped on temperature. If
the selected defrost stop sensor does not reach the
set defrost stop temperature limit within the set time,
the defrost will be stopped anyway.
d29
d29 MaxDefTime2
Defrost start interval The function is zeroset and will start the timer func-
tion at each defrost start. When the time has expired
the function will start a defrost. The function is used
as a simple defrost start, or it may be used as a safe-
guard if the normal signal fails to appear. If master/
slave defrost without clock function or without data
communication is used, the interval time will be used
as max. time between defrosts. If a defrost start via
data communcation does not take place, the interval
time will be used as max. time between de-
frosts.When there is defrost with clock function or da-
ta communication, the interval time must be set for a
somewhat longer period of time than the planned
one. In connection with power failure the interval
time will be maintained, and when the power returns
the interval time will continue from the maintained
value. he interval time is not active when set to 0
d03
d03 Def.Interval
Time staggering
power up
Time staggering for defrost cutins during start-up The
function is only relevant if you have several refrigera-
tion appliances or groups where you want the defrost
to be staggered in relation to one another. The func-
tion is furthermore only relevant if you have chosen
defrost with interval start. The function delays the in-
terval time by the set number of minutes, but it only
does it once, and this at the very first defrost taking
place when voltage is connected to the controller.
The function will be active after each and every pow-
er failure.
d05
d05 Time stagg.
Max thermostat run-
time
Defrost on demand – aggregate refrigeration time Set
here is the refrigeration time allowed without de-
frosts. If the time is passed, a defrost will be started.
With setting = 0 the function is not in use.
d18
d18 MaxTherRunT.
Pump down delay
Set the time where the evaporator is emptied of re-
frigerant prior to the actual defrost cycle
d16
d16 Pump dwn del
Drip off time
Here you set the time that is to elapse from a defrost
and until the compressor is to start again. (The time
when water drips off the evaporator).
d06
d06 DripOff time
Max hold time
Max. standby time after coordinated defrost. When a
controller has completed a defrost it will wait for a
signal which tells that the refrigeration may be re-
sumed. If this signal fails to appear for one reason or
another, the controller will itself start the refrigeration
when this standby time has elapsed.
