1. INSTRUMENT DESCRIPTION
1.1 General description
The model e34B is a microprocessor based digital electronic
temperature controller that is typically used in cooling applica-
tions with
ON/OFF temperature control and defrost control
at time intervals, by arrival at temperature or by length of time
of continuous compressor operation through stopping the
compressor, electric heating or hot gas/cycle inversion.
The controller is equipped with special
defrost optimization
functions and with other functions that can be used to obtain
energy savings from the controlled system .
The instrument has up to
4 relay outputs
and up to
3 NTC
temperature probes
inputs
one of which
can be
config-
ured as digital input
.
The instrument has an
internal buzzer
for the
acoustic
alarms
signalling and a
voltage alarm system
that deacti-
vates the outputs if the
mains voltage
is
too high/low
.
