EWDR 983 - EWDR 983/CS LX
The EWDR983 controller has three analogue inputs for
NTC temperature probes (parameter selectable PTC)
and two digital relay outputs for the compressor and
defrosting. This controller also has a configurable
12V-20mA output to manage additional loads like
alarms. Defrost cycles can be stopped at a specific time
or as soon as the end cycle temperature is reached
(if the evaporator is equipped with a specific probe).
The three analogue inputs can be used for temperature
control, to manage the defrost cycle and to display the
related values (or to manage the defrost cycle of the
second evaporator).
The values measured by the probes are displayed with
three digits and a minus sign. The decimal point can be
set with a parameter. The buzzer is optional.
All models have TTL connections that enable the
controllers to be used with Copy Card, the quick
programming accessory.
The /C models also have:
• an internal clock (RTC) to manage the defrost cycle
and the night and day function.
The /CS LX models also have:
• an internal clock (RTC) to manage the defrost cycle
and the night and day function.
• an internal opto-insulated RS485 internal connection
and
• can be connected to TelevisSystem.
All models have two voltage-free programmable
digital inputs.
The power supply is 230Va.

EWDR 985 - EWDR 985/CS LX
The EWDR985 controller has three analogue inputs for
NTC temperature probes (parameter selectable PTC)
and four digital relay outputs to manage the
compressors, defrost cycle, the luminous indicators and
the fans or the auxiliary ON/OFF function.
This controller also has a configurable 12V-20mA
output to manage additional loads like alarms.
Defrost cycles can be stopped at a specific time or as
soon as the end cycle temperature is reached (if the
evaporator is equipped with a specific probe).
