ELECTRICAL WIRINGS
For the electrical wirings please refer to the wiring diagram and technical
characteristics of the panel model to be installed.
Panel power supply must be on a dedicated line, and must be placed a
device suitable for protection against indirect contacts upstream the line
(differential interruptor).
Do not fit power supply wiring and signal wiring (probes/sensors and
digital inputs) in the same raceways or ducts.
Do not use multi-polar cables in which there are wires connected to
inductive/power loads or signalling wires (e.g. probes/sensors and digital
inputs).
Minimise the length of connector wires so that wiring does not twist into a
spiral shape as this could have negative effects on the electronics.
When it is necessary to make a probe/sensor extension, the wires must
have a cross-section of at least 1 mm2.
All wiring must be of a cross-section suitable for relevant power levels.
Insulation degree must be compatible with the applied voltages.
toxic smoke emission if interested by fire.
It is obligatory to connect clamp marked with PE abbreviation to the
ground of the supply system. If necessary, please verify ground system
efficiency.
Do not connect to the PE clamp conductors different from the external
protection one.

VERIFICATIONS BEFORE USE
After doing the wirings, please verify using the wiring diagram on the
correct execution of the connections.
Please check the correct screw clamping.
Check, when possible, the correct functioning of the outside protection
devices.
Please correctly calibrate the motor circuit breaker (if present) dedicated
to the compressor as indicated in the next chapter.
After powering the electrical panel please check the correct current
absorption on the loads, and after few hours of functioning check the
good tightening of screws on terminal blocks (included power supply line
connection). Warning: before doing that it’s necessary to cut off power
sectioning power supply upstream the line and block it with a padlock for
max. safety. Before any operation verify with a tester the absence of
voltage.

calibration basing on the measured
absorption. Any way the set up value
must not be higher than the one

GENERAL
To enhance safety and simplify the operator’s work, the ECP300 EXPERT has two
programming levels; the first level (Level 1) is used to configure the frequently-modified
SETPOINT parameters. The second programming level (Level 2) is for general parameter
programming of the various controller work.
It is not possible to access the Level 2 programming directly from Level 1: you must exit the
programming mode first.
KEY TO SYMBOLS
For purposes of practicality the following symbols are used:
• (t) the UP key is used to increase values and mute the alarm.
• (u) the DOWN key is used to decrease values and force defrosting.
SETTING AND DISPLAYING THE SET POINTS
1. Press the SET key to display the current SETPOINT (temperature)
2. Hold down the SET key and press the (t) or (u) keys to modify the SETPOINT.
Release the SET key to return to cold room temperature display: the new setting will be saved
automatically.

SWITCHING ON ECP300 EXPERT PANEL
After wiring the electronic controller correctly, power up at 400 V AC; the display panel will
immediately emit a beep and all the LEDs will come on simultaneously for a few seconds.
COMPRESSOR ACTIVATION/DEACTIVATION CONDITIONS
The ECP300 EXPERT controller activates the compressor when cold room temperature
exceeds setting+differential (r0); it deactivates the compressor when cold room temperature is
lower than the setting.
Nel caso venga selezionata la funzione Pump-down fare riferimento al capitolo 5.14 per le
condizioni di attivazione/disattivazione compressore.
MANUAL DEFROSTING
To defrost just press the dedicated key (see section 5.2) to activate the elements relay.
Defrosting will not take place if the end-of-defrost temperature setting (d2) is lower than the
temperature detected by the evaporator sensor. Defrosting ends when the end-of-defrost
temperature (d2) or maximum defrost time (d3) is reached.

sensor
• Check that defrost sensor is
working properly
• If the problems persists replace
the sensor
• Switch unit off and back on
• Reset the alarm input inside the
cold room
• Check that compressor is working
properly
• Check compressor absorption
• If the problem persists contact the
technical assistance service
• Check door switch status
• Check door switch connections
• If the problem persists contact the
technical assistance service

In case no alarm code is present below are indicated some of the most common causes that can result
in anomalies. These causes may be referable to internal or external problems of the panel.

• Check the ambient probe connections
• If the problem persists replace the probe
• Before reinserting the magnetothermic
circuit breaker please check that no shortcircuits are present. Reinsert then
magnetothermic circuit breaker verifying
all the absorptions to identify any
anomalies.
• Before reinserting the magnetothermic
circuit breaker please check that no shortcircuits are present. Reinsert then

• Check that transformer output absorption
not exceeding 0.25A.
• Check that on clamps for Kriwan supply
no other users are connected.
• Check that no short-circuits are present
on transformer output.

• Check wirings, calibration and correct
working of compressor and sensors.
• In case system is starting for the very first
time please check the presence of bridge
for Pump-Donw/Thermostat functioning

CHAPTER 8: MAINTENANCE
CHAP. 8 - Maintenance
GENERAL SECURITY RULES
For any type of maintenance , it must be exclusively executed by skilled technical staff.
In case of break down or maintenance to the electrical system, before
proceeding please cut off voltage to the panel placing general power supply
switch on open position (O). Check the absence of voltage with a tester
before doing any operation.
Each element of the panel, if defective, must be replaced only with original
spare parts.
If the intervention is on external parts of panel follow the next steps:
Switch off safely the panel power supply in one of the following ways:
1) Put 300 Expert main switch on OFF position and block it with a
mechanical block (Pego accessories ACC5ST3801) and then using a
padlock.
2) Cut off power supply upstream the panel permanently, using a padlock
(on OFF position).
Place signals indicating maintenaince in progress.
Before proceeding with maintenance operations please follow these security
prescriptions:
The electrical panel must be without voltage.
Prevent the presence of unauthorized staff around the intervention area.
Positioning of suitable notices to signal "Device under maintenance".

Remove if worn, every object which can get entangled in any part of the
panel.
Suitable tools for the maintenance operations must be at disposal.
Tools must be correctly cleaned and greased.
Necessary technical documentation to execute maintenance intervention
must be at disposal (wiring diagrams, tables, drawings, etcc….)
At the end of the maintenance operations please remove all the residual
materials and make a careful cleaning inside the panel.
It’s absolutely forbidden to accomodate additional parts inside the panel.
