Electronic Temperature Control Systems

DESCRIPTION

The VCPL series is especially designed for
use in the commercial refrigeration and is
available in various different models. The
VCPL is also available with communication
properties.
In addition to extremely accurate temperature
control the VCPL offers the user diagnostics,
marketing information and current statistics
scroll i.e. average temperature, lowest
temperature, highest temperature, number of
door openings, compressor cycles and
compressor running hours.
As standard all models in the VCPL series ar e
fitted with 6 relays switching : compressor,
heating element or solenoid valve, external
alarm, evaporator fan, on/off switch and
light(s). All relays in this unit have a switching
capacity of 16 Amp. @ 240 Volt.

WARNING

This manual is part of t he product and should be kept
near the inst r ument for quic k reference.
The i n strument should not b e used for pu r poses other
than desc ribed and /or speci fied by the manufac turer.
These controls can only be used with GE double
insulated sensors.

SAFETY PRECAUTIONS

Ensure that the supply voltage is correct before
connecting the instrument. (240 Volt )
Ensure th at t he inst ru me nt is not e xpos ed to w ater o r
any other liquid.
Ensure that the current that is switched does not
exceed the maximum switching capacity of the
instrument. If the current to be switched is greater
than the instr ument limits , a sepa rate relay sho uld be
installed.
Ensure that all wires are properly connected in the
appropriate terminal, a loose wire could cause
sparking and damage the instrument and may be
dangerous.

BUTTON COMMANDS

TO SET THE T EMPERATURE

In case of a n instru ment fa ilure or faulty functio ning
of the instrume nt, retur n it to your loc al dis t ribut or or
direct to the ma nufacturer. If the unit is still in it s
warranty period it will be rep laced free of charge.
To set the temperature push the ‘

’ and the d isplay will intermittentl y show the

button

letters SP (set point) and the pre-set temperat ure. To
increase the tempe rature use t he value up button (∧),
to decrease the temperature use the value down
button (v).
Once the required tempe rat ure is selecte d, re lease the
buttons and wait until the display shows the actual
temperature again. The instr ument has now adopted
the new setting and will operate in accordance with
these new instructions.

ACTIVATE A MANUAL

It may be possible that from time to time the user

DEFROST CYCLE

wants to use some extra defrost cycle(s). To activate
a manual defrost, p ush the manual defrost button and
keep it pressed for a minimum of 5 sec. Until the
defrost signal shows on the display.
A manual defrost may be activated as many times as
required.

WARNING SIGNALS

In addition to its standard control fun ctions , the GE­VCPL series also contains a number of diagnostic
functions and can show the following alarm signals:
RSF – There is a refrigeration system failure.
Contact your sup plie r .

EE – There is a microprocessor (electronic) failure,
contact you r su pplier.

PF1 – There is a sensor failure that is very likely
caused by a lo ose connection of the s ensor wire in
the terminal block of the instrument. This sensor is
the appliance sensor. Contact your local supplier.

PF2 – There is a sensor failure (as PF1), but in t he
sensor of the evaporator.

PF3 - As PF1 and PF2 but this is the sensor
connected to the condenser

AL1 – The temperature of the appliance has
exceeded its maximum allowable temperature.

AL2 – The temperature of the appliance has
exceeded the minimum allowable temperature.

HT – The condenser is blocke d

CHANGING PARAMETER VALUES

To change the parameter values switch the power to
the unit off, push the temperature set button and keep
it pushed w hilst switching t he power on aga in. The
display wi ll fla sh and inter mitte ntly s how the figu res

888. Once the display stops flashing, the instrument
is in parameter mode and the values can now be
changed.
To scroll through the parameters push the
temperature set button and to change the value of the
parameters use the ‘value’ buttons.
When finished, release all buttons and wait until the
display shows the actual temperature again.

Please note that th e VCPL has two different
sets of parameters. The first batch can be
accessed as described above and the second
set can be accessed by holding the set button

and the up button pushed together

.

WARNING

If the power to the unit is switched off whilst the
instrume nt is st ill in para me ter mode, the syste m w il l
NOT accept the changes.

The GE-VCPL does NOT require any maintenance.

WARNING

To clean the fac ia of the GE-VCPL use wet soapy
rag.
The instrument is an electronic device, do not use
water or any other cleani ng liquid to clean the facia
of the instrument as this may cause serious and
unnecessary damage to the system and may be
dangerous.

All wiring instructio ns are pr inted on the ho using o f
the unit and contain all possible information needed
to connect the GE-VCPL
Follow these instructions and ensure that all
connections in the terminals of the instrument are
properly fastened as loose connections may influence
the performance of the instrument and may cause
sparking.
The GE-VCPL is powered by 240 Volt and should be
connected dir ec t to the ma ins.

IMPORTANT

Only authorised and competent personnel should
connect and/or disconnect the GE-VCPL.

MAINTENANCE

WIRING INSTRUCTIONS

The recommended hole s ize for the GE-VCPL is 9
5/32” x 3 5/8”but in addition there are the holes for
the fasteners as per the drawing on the reverse of
this instruction manual.
