(*) START or END are set in the memory with the PC or with the programming

push-buttons.

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.

2. Power up the module.

3. Supply a calibrator or simulator of the signal you wish to measure and retrans-

mit.

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.

Selecting output

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.

Setting with a PC

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.

• Additional input types

• 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

50Hz)

• 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

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

of suitable size.

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

conditions exists.

• If panel temperature exceed 35 °C and at least two of the severe operating

conditions exists.

Electrical connections

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.
