1. Generality
The device of control temperatures TEMON 4 is used in the control of electric machine, transformer, motor, etc.
where it’s possible to control the temperature level signalling the critical temperature condition or to disable the
machine under control. For example for the control the temperature of supplying transformer, where it’s possible to
control the temperatures of three coils of phase and the nucleus, using the tripped output (TRIP) to cut off the load
and eventually the functions of ventilation control.
Another important function is the presence of one port of serial communication RS485, that allows the connection
to system of acquisition (PC, PLC, scada, etc.) of the measure data, control and programming of the device.
The MODBUS-RTU is the protocol used, it’s documented in a specific manual.
A software for Windows environment is available for a management of the devices with complete function of
control, storing data, recording alarm, etc.
It’s available a analogue output settable 0-20 or 4-20 mA with end-scale 200°C to join to one of channel or to the
higher of the 4 temperature channels.
2. Introduction
The device type TEMON 4 allows the control and the visualization of temperature read with probe type RTD
PT100.
For each channel of measure are available two levels of alarm (alarm-tripped) that active the commutation of the
relative output relay for signalling at distance or to disable the machine under control. On front of the instrument on
a double display at 3 digit, it’s possible the visualization of the temperatures, the visualization of the status of the
alarm of the measure channels and 5 button for the programming. The instrument is completed by the functions of
ventilation control, storing maximum values and storing of the tripped.
3. Accessories and Options
accessories: transparent cover of frontal protection
options: serial output RS485
analogical output 0-20mA (4-20mA)
4. Installation
Foreward
Read carefully the present manual before to install and use the device.
The device described in this manual must be installed and used by personal opportunely learned.
Security.
Before to proceed at the installation it’s necessary verify if the device is intact and it haven’t damages caused by
transport. The power supply must be compatible with the tool range. The instrument installation must be done in
total absence of voltage and observing the security norm in force. All operation of maintenance and reparation
executed by not authorized person are forbidden. If during of functioning the device loose the security, it’s
necessary to put it out of service and to be sure that this device will not use unintentionally.
The use can be considered insecure when the instrument: - don’t function regularly / - have damage clearly
visible / - have damage caused of transport / - is stored in bad condition

5. Connection of the Thermometer Sensors
For the connection of the thermometer sensor RTD Pt100 it’s necessary to follow the indication of the wiring
diagram of this manual: pay attention not to invert the position between the conductors with red insulator and the
conductor with white insulator. The probes type PT100 with 3 wires use a third wire to compensate the resistance
of the conductors. If the sensor has 2 wires (normally white and red) it’s necessary to short-circuit the terminals with
the red wires (1-2, 4-5, 7-8, 10-11).
To reduce the external noises it’s necessary to use the following indication for the wires of measure of the Pt100:
to use probes with shielded wire connected at earth and wires twisted
to separate the wires of the probes from wires of power
to use wires with section higher than 0,5 mm2
to use wires with conductor with tin or silver-plated
6. Output Relays
For the connection of the output contacts of relays it’s necessary to follow the indication in the diagram.
The ALARM and TRIP relays commute when the threshold set are to get over.
The FAULT relay is normally energized and it commute in presence of an anomaly on the Pt100 or on device.
During the normally functioning of the device the contact 38-39 will be open while the 39-40 will be closed.
The FAN relay is used to control the fun of cooler, in function of the threshold set of switch on and switch off.

9. Programming of the Device
When the device is switched on, on the display will flash the index of the internal software: later the device starts to
display the temperature read on the measure input.
To enter in the programming phase press the button SET for some second up to light the relative LED of signalling
SET. The settings are indicated in sequence like showed after; to go out of the programming phase without to
modify the values it’s necessary to press SET without to confirm with the ENTER key the data modified.
To modify the value or the status it’s necessary to use and keys and the ENTER key to store the modification.
The pressure of the ENTER key move automatically the programming at the successive function or value.
9.1 - Selection of the HOLD function
The function Hold is the first function to set in the menu programming (SET): in this phase of programming the
HOLD led switch on.
The Hold function allows to store the alarm condition that can be rearmed only manually with the RESET button
when the temperature are lower than the threshold set.
If this function is disabled it’s possible to rearm the ALARM with the RESET button even if the temperature is
higher than the threshold set, while the value of temperature come back under the threshold set the alarm will be
automatically deleted.
To set the Hold function it’s necessary to use the and keys:
OFF function disabled
ON function enabled
Press the ENTER key to confirm the operation.
9.2 - Selection of the number of active inputs
After the setting of the Hold function, it’s possible to select the number of activated inputs.
It’s possible to select between 3 or 4 active inputs; in case of 3 active inputs the display T4 remain off.
