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.
