2. Protect the device by means of extra quick
fuse 250 V 5A
3. The power supply frequency can be chosen

THERMOMETER SENSORS CONNECTION (INLETS)
The electrical wiring to the temperature probes
must be carried out through shielded and roped
cables. If the shield is included, the connection
cables and probes shield must be grounded.
PRESCRIPTIONS
1. The signal cables must be separated from the
power cables (minimum 1 meter)
2. The signal cables must be placed in specific
cable racks
3. The signal cables section must not be less
than 1 mm2
4. All the connections to the terminal boards
must be properly fixed
5. The connections must be installed in places
properly protected against electromagnetic
frequency interferences such as those resulting
from the inverters or similar equipment.
The probe cables are compensating, therefore
the probes have three conductors. Connect

DESCRIPTION
ACTIONS
INTERVENTION
It is an alarm signal, indicating when a critical status
is reached for the functioning of the controlled
equipment.
- The FAN relay energizes
- The related FAN led switches on
- When the temperature of a channel is higher than
the limit of the threshold parameter "H"
- When the temperature of a channel has exceeded
the limit of the threshold parameter "H" and isn't
lower than the limit of the threshold parameter "L"
- To avoid the binding of the blowers bearings when
the control parameter "C" is set on value 1 or 2
- As a precaution, in case of one or more damaged
probes
FAULT
ACTIONS
This is an anomaly of the temperature detection
system due to the power unit, the probes or the
connections. The FAULT signal is not switched off
automatically because even if the channel is
acknowledged within the parameters, this does not
imply the problem has been solved.
- The FAULT relay energizes
- The related FAULT led flashes
 Quick flashing: display of damaged channel
 Slow flashing: signals that at least one
currently not displayed probe is damaged.
By placing on the related damaged channel,
32
Page 8 of 25
INTERVENTION
-
on the screen there can be the flashing
indication n ICF or n SCF, where n indicates
the number of the damaged channel. In
case a temperature is displayed, it means
that the channel has previously experienced
abnormal travels (see INTERVENTION
section). By scrolling with the keys, it is
possible to observe the status of the other
channels.
Lack of supply voltage to the power unit
Breakdown in the power unit
Breakdown or anomaly in the thermometer
probes (see table 1)
The value of the read temperature is higher than
200°C
Interrupted probe
The value of the read temperature is lower than
-10°C
Short circuit probe
Unreliable reading: The value of the read
temperature is highly variable through a
dynamic which is not compatible with the
dynamic of the equipment to control. There
could be some micro-interruptions of the signal
or some short-term short circuits. The
measurement signal could be disturbed. In this
case, a value that the power unit infers starting
from the inlet signal appears on the monitor of
the power unit. The indication of the channel
deemed damaged will not be assessed for the
device protection purposes. By scrolling with
the keys, it is possible to observe the status of
the other channels.
CCT 442
In case of fault of the active probes, the output
4-20mA or 0-20mA is switched off at zero
33

CONSEQUENCES
whatever the chosen configuration.
Unreliability of the equipment.
Immediately control the system and the
transformer
In order to acknowledge the FAULT signal, press at
the same time for 5 seconds the keys
AUTO/MANUAL/SCAN and ARROW UP. (In the
panel, the two keys are connected by the graphic
RESET sign)
Check:
- the arrangement of the probe cables
- the presence of inverters
- that the connections to the junction boxes are
adequate
ALARM
DESCRIPTION
ACTIONS
INTERVENTION
CONSEQUENCES
This is the alarm signal which indicates when a
critical status is reached for the functioning of the
controlled equipment.
- The ALARM relay energizes
- The related ALARM led switches on
- Exceeding the alarm temperature "A". The value
of the measured temperature is higher than the
temperature set for the alarm.
- Breakdown or anomaly to the thermometer
probes (see table no. 1 "relay interventions")
Immediately control the probes and the
transformer
34
Page 10 of 25
INTERVENTION
CONSEQUENCES
It signals when an extreme status is reached for
the functioning of the controlled equipment. The
equipment is immediately put out of service.
- The TRIP relay energizes
- The related TRIP led switches on
- Exceeding the trip temperature "t”. The value of
the measured temperature is higher than the
temperature set for the trip.
- Breakdown or anomaly to the thermometer
probes (see table no. 1 "relay interventions")
- The trip signal switches on continuously until
the temperature read on at least one channel is
higher than the trip temperature. In case of
damaged probes, the status remains the same.
- The equipment is immediately put out of
service.

DESCRIPTION
KEYS
By scrolling with the keys UP and DOWN, it is
possible to display all the power unit
parameters; in particular it is possible to have a
look at the threshold set values and the
information on any anomaly found in the
different channels. The anomalies are displayed
as follows: on the CHANNEL screen there is the
channel number, on the TEMPERATURE screen
there is the type of anomaly, "SCF", "ICF", "dEr".
The next indication refers to the number of times
the anomaly has been detected. The anomalies
displays have the following meanings:
“SCF", short circuit probe or temperature
permanently lower than -10°C
"ICF" interrupted probe or temperature
permanently higher than 200°C
"dEr" probes which has, or had in the past,
travels incompatible with the thermal inertia of

Press the key
EXIT FROM
«AUTO-MANUALTEST MENU
SCAN».
The pressure of the key «AUTO-MANUAL-SCAN» causes, at any
time, the exit from the RELAY TEST menu.
For safety reasons, the time remaining into the menu necessary
for the programming is in every case controlled. After more than
one minute without activity by the operator, the power unit goes
back to the automatic display mode.

12 Warranty rules
The CCT 440, CCT 441 and CCT 442 power units are covered by warranty for
a period of 1 year from the testing date indicated both on the label and in the
attached manual. The warranty is considered valid until it is sure that the
cause of a failure are due to production defects or wrong calibration of the
probes. We are not responsible for failures due to a wrong wiring of the
probes, tampering with the power unit or wrong supply voltage (for ex. 400
Volt AC).
13 Warning
Do not carry out dielectric strength or partial discharges tests on the electric
machines with the power unit inserted. Do not directly connect the power
unit to the secondary winding of the transformer to protect. Without
protection, when closing the switch placed downstream of the transformer,
there could be over voltages that can damage the device. The problem may
occur frequently when the supply voltage of the power unit is 230 V and if
there are power factor correction capacitors.
