.1 - GENERAL DESCRIPTION

The models 

TLB 55

 (Display and control unit) and 

BSLB4

 (Supply

and outputs unit) are a digital controller system with
microprocessor that is typically used in cooling applications that
have temperature control with ON/OFF regulation and defrosting
control with set time by means of electrical heating or hot
gas/reverse cycle.
The system has up to 4 relay outputs, 2 inputs for PTC or NTC
temperature probes and  2 digital inputs, that can all be configured.
The 4 outputs at main voltage (in BSL unit) can be used for
controlling the compressor or the temperature control device, the
defrosting device, the evaporation fan and an alarm or an auxiliary
device (light, second compressor etc.) .
The two inputs for the PTC and NTC temperature probes (which
can be selected by parameter) connected to TLB55 unit can be
used to measure the cell temperature (Pr1) and the evaporator
temperature (Pr2) while the digital inputs (DIG1,2) can be
programmed to carry out various functions such as defrosting
commands, selecting 2 or 4 different set of temperature
regulations, external alarm signals, activating a continuous cycle,
and activating an auxiliary output etc.
