GENERAL DESCRIPTION
The ID400 is a microprocessor-based digital device used for the control of refrigeration
units. It is particularly suitable for applications on "static" units at low or normal temper-
ature.
It has a relay output that controls the compressor and an NTC probe input (or PTC accord-
ing to availability) that controls cell temperature. Defrosting is effected by simply shutting
down the compressor. A series of alphanumeric parameters is used to configure the instru-
ment according to the application. The ID 400 is supplied in the ELIWELL standard 32x74
format
.

FUNCTIONS
DEFROST CONTROL
The defrost cycle can be activated manual-
ly using the keyboard or automatically at
set intervals.
Defrost mode
The compressor remains off for the dura-
tion of defrosting. Defrosting terminates
only when the time out set with parameter
dE (defrost time out) expires.
Manual defrosting
Press the "UP" button to activate the defrost
cycle manually.
If parameter Od is set to a value that is not
0 the cycle does not start, the request is
ignored and the display will flash three
times to indicate that defrosting is not pos-
sible.
Automatic defrosting
The defrost cycle is programmed to start at
set intervals determined by the value of
parameter dt. If parameter dt is set at
0 the defrost cycle cannot be activated. If
dt is higher than 0 then the time interval
between defrosting can be counted
