Electrical circuit

3.4.1 Checks and connections
!
Before carrying out any operation on the electrical system, make
sure that the appliance is disconnected from the electrical power sup-
ply.
All electrical connections must comply with the applicable regulations
in force in the country of installation.
Initial checks
1) Th e power supply voltage and frequency must correspond to the
values stamped on the chiller nameplate. Th e power supply charac-
teristics must not deviate, even for brief periods, from the tolerance
limits indicated on the electrical diagram , which are +/- 10% for the
voltage; +/- 1% for the frequency.
2) Th e power supply must be symmetrical (the eff ective voltages and
the phase angles of consecutive phases must be equal). Th e maxi-
mum permissible voltage imbalance is 2%.
Connection
1) Th e electrical power supply must be connected to the chiller using a
4-wire cable, comprising 3 phase conductors and an earth conductor,
with no neutral. For minimum cable section, see par. 7.3.
2) Pass the cable through the cable entry on the rear panel of the ma-
chine and connect the phase and neutral to the terminals of the main
isolator switch (QS); connect the earth wire to the earth terminal
(PE).
3) Ensure that supply cable has at its source protection against direct
contact of at least IP2X or IPXXB.
4) On the supply line to the chiller, install a residual-current circuit
breaker with a trip rating of (RCCB - IDn = 0.3A), with the current
rating indicated in the reference electrical diagram, and with a short
circuit current rating appropriate to the short circuit fault current
existing in the machine installation area.
Th e nominal current In of the magnetic circuit breaker must be
equal to the FLA with an intervention curve type D.
5) Max. grid impedance value = 0.274 ohm.
Subsequent checks
Check that the machine and the auxiliary equipment are earthed and
protected against short circuit and/or overload.
!
Once the unit has been connected and the upstream main switch
closed (thereby connecting the power supply to the machine), the
voltage in the electrical circuit will reach dangerous levels. Maximum

caution is required!
3.4.2 General alarm
All the chillers are equipped with an alarm signalling system (see
electrical diagram), comprised of a switching free contact in a terminal
block: this may be used for the connection of an external audible or
visual alarm, or used to provide an input signal for a logic control
system such as a PLC.
3.4.3 ON/OFF remoto
All the chillers can be connected to a remote ON/OFF control.
See the electrical diagram for the connection of the remote ON-OFF
contact.
3.4.4 Phases Monitor
If appears to display the alarm "tp ", during the start up of the chiller,
the user must verify the wiring of the input terminals of the discon-
necting switch of the dryer.

Starting the chiller

• Connect the power supply to the machine by turning the main
isolator switch QS to ON.
• Turn the chiller `ON' by pressing the key S1.
• Set the desired temperature on the controller.
4.2.1 Adjustments at commissioning
a) Th e chiller is set for operation at a default temperature of 12 °C with
a diff erential of 3 °C; to adopt a new setting, see heading 4.5.
b) Verify correct operation of the pump, using the pressure gauge
(read P1 and P0) and checking the pressure limit values (Pmax and
Pmin) indicated on the pump data plate.
P1 = pressure with pump ON
P0 = pressure with pump OFF
Pmin < (P1-P0) < Pmax
- Example n°1.
Conditions:
closed circuit, pressure P0 = 2 bar
pump data plate values: Pmin 1 bar/ Pmax 3 bar
I9 P1 P3
adjust the valve outlet to give a pressure of 3 bar < P1< 5 bar
- Example n°2.
Conditions:
open circuit, pressure P0 = 0 bar
PRG

SEL
adjust the valve outlet to give a pressure of 1 bar < P1 < 3 bar
c) Verify correct operation of the pump similarly under normal run-
ning conditions.
Check also that the amperage of the pump is within the limits indi-
I5 I6 I7 I8 P2 P4
cated on the data plate.
d) Switch off the chiller and proceed to top up the hydraulic circuit at
the "SET" temperature.
e) Check that the temperature of the "treated" water does not fall
below 5 °C and that the ambient temperature in which the hydraulic
circuit operates does not fall below 5 °C. If the temperature is too
low, add the appropriate quantity of glycol, as explained under head-
ing 3.3.2
4.3

Stopping the chiller

When chiller operation is no longer required, turn the chiller off as fol-
lows: turn the On/Off [S1] switch to Off .
Do not turn off the main switch QS to ensure that any antifreeze pro-
tection devices will still receive electrical power.
