(*) START or END are set in the memory with the PC or with the programming
N.B.: DIP-switches must be set while the module is powered down, other-
wise, the module may be damaged!
Setting START and END at will
The START and END push-buttons under the SW2 DIP-switch group allow to set
the beginning and end scale at will within the scale pre-set through the DIP-swit-
ches. To obtain this facility it is necessary to use a suitable signal generator, able
to furnish the desidered values of beginning and end scale.
The procedure is following:
1. Set through DIP-switches, the type of input, START and END measurement
which include the required beginning and end values.
3. Supply a calibrator or simulator of the signal you wish to measure and retrans-
4. Set the required START value on the calibrator (or other instrument).
5. Press the START push-button for at least 3 sec. The green LED on the front
panel fl ashes to indicate the value has been stored.
6. Repeat points 4 and 5 for the required END value.
7. Cut power to the module and set to OFF position the DIP-switches of group
SW2, correspondent to the settings of START and END values.
The module is now confi gured for the required start and end scale. To reprogram
it (e.g. for a different type of input) repeat the whole procedure.
DIP-switches numbers 7 and 8 of the SW2 group enable you to set the output
with or without zero elevation, or as a normal or reversed output. The SW3 DIP-
switch group enables you to select the output type.
N.B.: DIP-switches must be set while the module is powered down, avoiding
electrostatic discharges, otherwise the module may be damaged.

By using a PC and V620/V622-C software, it is possible to set other normally
fi xed parameters in addition to start and end scale.
• Digital fi lter (normally disabled)
• Square root extraction (normally disabled)
• Negative burn-out (normally positive)
• Alarm (normally set as error signalling)
• Start and end scale of the analog output
• Value of the analog output in case of error
• Rejection programmable for 50 or 60 Hz mains frequency (normally set to
• Sampling frequency/resolution (normally set to 15 sps/16 bits)
• 3 or 4 wires measure for thermal resistance (normally set to 3 wires)
• Action of the digital output alarm in case of fault.
Instructions for setting and for the connection cable are supplied with the soft-
ware (to be requested as an accessory item).

Power supply voltage must be in the range 10 to
40 V DC (at any polarity), 19 to 28 V AC; also see
section “Installation instructions”.
The upper limits must not be exceeded, to
avoid serious damage to the module. Protect
the power supply source against possible damage of the module by using a fuse

Installation instructions
The module was designed for fi tting to guide 46277, in a vertical position. For
optimum operation and long life, make sure adequate ventilation is provided for
the module/s, avoiding placing raceways or other objects which could obstruct
the ventilation grilles. Do not install the modules above appliances generating
heat we advise you to install in the lower part of the panel.
Severe operating conditions
Severe operating conditions are as follows:
• High power supply voltage (> 30 V DC / > 26 V AC).
• Power supply of the sensor at input.
• Use of the output on generated current.
When modules are installed side by side, it may by necessary to separate them
by at least 5 mm in the following cases:
• If panel temperature exceed 45 °C and at least one of the severe operating
• If panel temperature exceed 35 °C and at least two of the severe operating
We advise you to use shielded cables for connecting signals. The shield must
be connected to an earth wire used specifi cally for instrumentation. Moreover,
it is good practice to avoid routing conductors near power appliances such as
inverters, motors, induction ovens, etc.
