GENERAL

The electronic controllers of the ECP202 EXPERT + BASE series have been designed to

control static or ventilated cold rooms.

The ECP202 EXPERT + BASEelectronic board allows the user to control all the

components on a refrigeration unit such as compressor, evaporator fans, defrosting

elements and cold room light.

The applications are:

-single-phase static or ventilated refrigeration systems up to 2 HP, with off-cycle or

electrical defrosting.

-out of room unit to be connected to power board for compressor, defrosting and fan

start.

-single-phase evaporator control unit with cold solenoid consensus or remote

condensing unit consensus.

The ABS box is easy to install on the wall as the ECP202 EXPERT + BASE has a

minimum footprint and IP65 protection degree.

PRODUCT ID CODES

200202EXBCS Control and management of the compressor,

defrosting heaters, evaporator fans and cold

room light. Two configurable auxiliary relays.

16A differential magnetothermic protection.

IMPORTANT INFORMATION FOR THE INSTALLER

1. Install the device in places where the protection rating is observed and try not to

damage the box when drilling holes for wire/pipe seats.

2. 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).

3. Do not fit power supply wiring and signal wiring (probes/sensors and digital inputs) in

the same raceways or ducts.

4. 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.

5. Fit a general protection fuse upstream from the electronic controller.

6. All wiring must be of a cross-section suitable for relevant power levels.

7. When it is necessary to make a probe/sensor extension, the wires must have a cross-

section of at least 1mm2. Probes extension or shortening could alter their factory

calibration; then proceed with the verification and calibration, using an external

thermometer.

STANDARD ASSEMBLY KIT

The ECP202 EXPERT + BASE electronic controller, for assembly and use, is equipped

with:

•Nr 3 seals, to be fitted between the fixing screws and the box back panel;

•Nr 1 user’s manual.

INSTALLING THE UNIT

Fig. 1: Raise the transparent cover

that shields the magneto-thermal

cut-out switch and remove the

screw cover on the right-hand

side.

Fig. 2: Undo the 4 fixing screws at the front

of the box.

Fig. 3: Close the transparent cut-out switch

cover.

Fig. 4: Open the front of the box, lift it and

slide the two hinges out as far as

they will go.

Fig. 5: Press on the sides of the hinges to

remove them from their seats and

so remove the front panel

completely.



Fig. 6: Use the three existing holes to fix the

box back panel to the wall: use three

screws of a length suitable for the

thickness of the wall to which the

panel will be attached. Fit a rubber

washer (supplied) between each

screw and the box backing.

Fig. 7: Hook the frontal panel back up to the

lower part of the box by inserting the

two hinges in their seats and, bending

them, rotate downwards 180° to gain

access to the electronic board.

Make all electrical connections according to diagram A2.

To carry out the electrical connections reliably and maintain the degree of protection of the box, we

recommend using suitable cable glands and / or pipe clamps to tightly seal all the wiring.

It is advisable to distribute the cables within the panel as neatly as possible. In particular, keep the

power cables away from the signal cables. Use any sealing strips.

Fig. 8: Close the front panel, making sure that

all the wires are inside the box and that

the box seal sits in its seat properly.

Tighten the front panel using the 4

screws.

Give power supply to the panel and carry

out a scrupulous reading / programming

of all the parameters set.

Be careful not to over-tighten the closing screws as they could cause deformation of

the box and alter the correct operation and tactile effect of the panel keyboard.

On all loads connected to the ECP202 EXPERT + BASE electronic controller, install

overcurrent protection devices for short-circuits, to avoid damaging the device. Every

operation and / or maintenance operation must be carried out by disconnecting the panel from the

power supply and from all the possible inductive and power loads to which it is connected; this to

guarantee the maximum safety condition for the operator.
