electronic expansion valve ON / OFF with coil to 230VAC and single-phase compressor up
to 2 HP.
It allows the user to control all the components on a refrigerating system: compressor,
EEV pulse, evaporator fans, defrosting elements room light and thermostat-holder
demisting element.
APPLICATIONS:
-Complete management of single-phase static or ventilated refrigeration systems up to
2 HP, with off-cycle or electrical defrosting and with direct or pump-down compressor
stop.
-For plants with evaporator managed by the electronic expansion valve ON/OFF at
230Vac.
-Real time clock defrosting.
-Control of single-phase evaporator unit only with electronic expansion valve ON/OFF
230Vac or remote condensing unit enable signal.
MAIN CHARACTERISTICS:
-Compatible with 22 gases:
R404, R134, R22, R407A, R407F, R407H, R410A, R450A, R507, R513A, R744(CO2),
R449A, R290, R32, R448A, R452A, R600, R600A, R1270, R1234ze, R23, R717(NH3).
-Cold room temperature displaying and regulation with decimal point.
-Evaporator temperature displaying from parameter.
-Plant control activation/deactivation.
-Plant alarms signaling (probe error, minimum and maximum temperature alarm,
compressor protection).
-LED indicators and large display illustrate system status.
-User-friendly keypad.
-Evaporator fans management.
-Manual and automatic defrost (static, through heaters, through cycle reversal).
-Direct or pump-down management and control of condensing unit up to 2HP.
-Cold room light activation through key on the panel or through door-switch.
-Direct control of compressor, defrosting elements, evaporator fans, room light with
outputs directly connectable to the various units.
-Magneto-thermal cut-out switch for isolation and protection of the refrigeration unit.
-Innovative, smartly designed ABS cover with transparent cover for access to the
magneto-thermal cut-out switch, all with an IP65 protection rating so that panel can be
used outside the room.
-Auxiliary relay with parameter-configured.
-Possibility, as an alternative to an auxiliary relay, of a RS485 port for connection to the
TeleNET supervision net or to a net with MODBUS-RTU protocol.

GENERAL WARNINGS 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. All wiring must be of a cross-section suitable for relevant power levels.
6. 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; therefore to check and calibrate the probes through an external
thermometer.
STANDARD EQUIPMENT INCLUDED FOR INSTALLATION AND OPERATION
The electronic controller ECP200 EXPERT PULSE, is equipped with the following for
installation and operation:
• 3 sealing gaskets, to place between the fastening screws and the base of the box;
• 1 user manual.

protects the differential magneto
thermic circuit breaker and remove
the cover for the screws on the right
side.
Fig. 2: Remove the 4 fastening screws
from the front panel of the box.
Fig. 3: Close the transparent door that
protects the differential magneto

lifting it and sliding the two hinges
until they reach the end stop.

unlodge it and completely remove
the front panel.

Fig. 6: Use the three pre-existing holes to
fasten the base of the box with three
adequately long screws based on the
thickness of the wall that the panel will
be installed on. Place a rubber washer
(included) between each fastening
screw and the base of the box.
Fig. 7: Hook the front panel back on to the
base of the box by re-inserting the
hinges into their slots and making
them bend.
Rotate the panel downwards by 180°
to access the PCB.
Make all of the electrical connections according to the attached diagrams for the
corresponding model (see the relative tables in ANNEXES). To make the electrical
connections in a secure manner and maintain the degree of IP protection of the box it
is advisable to use suitable cable and/or conduit glands to seal all of the cables. It is
advisable to distribute the arrangement of the conductors inside the panel in the most orderly
manner possible, and especially keep the power conductors away from the signal ones. Use
sealing straps if necessary.
Fig. 8: Close the front panel again, paying
attention that the cables are inside the
box and that the gasket for the box is
correctly lodged into place. Fasten the
front panel with the 4 screws.
Power the panel and perform a
thorough reading/programming of all
of the set parameters.
Be sure not to tighten the closing screws excessively as this could cause the box to
become deformed and jeopardise its correct functioning and tactile effect of the
keyboard on the panel. Install protection devices against power surges for short-
circuits, in order to avoid damage to the device on all of the loads connected to the
electronic controller ECP200 EXPERT PULSE. Every time repair and/or maintenance is performed
the panel must be disconnected from the power supply and from all possible inductive and power
loads that it may be connected to; this is to guarantee the maximum safety conditions for the
operator.

3rd LEVEL PROGRAMMING (EEV PARAMETERS)
To access third level programming, keep the UP () and STAND-BY keys pressed for more than 3 seconds.
When the first programming variable appears, the system automatically switches to stand-by.
1. Select the variable to amend using key () or key (). After having selected the wanted variable it will be
possible:
2. To display its setting by pressing the SET key.
3. To amend the setting keeping the SET key pressed down, and press one of the () or () keys.
4. Once configuration values have been set, to exit the menu press the () and () keys;
Keep them simultaneously pressed for a few seconds, until the temperature value appears.
5. Memorisation of the amendments made to the variables will happen automatically when exiting the
configuration menu.
6. Press the STAND-BY key to enable electronic control.

ECt
Cycle time
This represents the sum of EEV valve opening / closing
cycle times. This is used to calculate the EEV opening and
closing times.
Example: if the EEV valve must be opened by 30% we will
have:
EEV valve opening time = ECt* 30/100
EEV valve closing time = ECt * (100-30)/100

LSH
LSH threshold (Low overheating temperature)
Overheating values that are too low can cause liquid to
return to the compressor or strong oscillations.
Below the LSH value the ELS protection intervenes and acts
by increasing the PID speed when closing the valve to reach
the set overheating set.

ELS
LSH protection
If enabled, when tSH < LSH the integration time for the PID
is set based on the ELS selection from 1 to 7.
The setting of 1 is the setting that generates a quicker
closing.
When this protection is entered the SHd count for LSH alarm
activation will begin.
THE LSH PROTECTION HAS PRIORITY OVER THE LOP
PROTECTION.
LSH PROTECTION IS NOT ACTIVATED.

SHd
Delay in activating the LSH alarm: the LSH overheating
alarm is signalled only after it has been active for the
amount of the SHd time. In case of an LSH alarm, the valve
closing is nevertheless instantaneous;
The alarm is self-restoring and stops when tSH ≥ LSH

MOP
MOP threshold (Maximum saturated evaporation
Temperature referred to the sensor S5)
This represents the maximum evaporation pressure,
expressed in saturated degrees, and activates the MOP
protection when it is exceeded (EMO parameter). If the
MOP kicks in the control will close the valve gradually
to limit the evaporation temperature and avoid the
compressor from stopping for thermal protection.

MOP protection (active with tS5>MOP )
With MOP protection on the valve abandons its control
PID and at any other cycle time it closes as established

Temperature referred to the sensor S5)
This represents the minimum evaporation pressure,
expressed in saturated degrees, and activates the LOP
protection when it falls below this value. In case of LOP
the control opens the valve to avoid the compressor
from stopping due to low pressure (mechanical
pressure switch).
