MOUNTING REQUIREMENTSMOUNTING REQUIREMENTS

MOUNTING REQUIREMENTS

MOUNTING REQUIREMENTSMOUNTING REQUIREMENTS

This instrument is intended for permanent installation, for indoor
use only, in an electrical panel which encloses the rear
housing, exposed terminals and wiring on the back.
Select a location, for instrument mounting, where minimum
vibrations are present and the ambient temperature is within 0
and 50 °C (32 and 122 °F).
The instrument can be mounted on a panel up to 15 mm thick
with a cutout of 92 x 45 mm (PKP) or 92 x 92 mm (MKP).
For outline and cutout dimensions refer to Fig. 2.
The surface texture of the panel must be better than 6,3 µm.
The instrument is shipped with rubber panel gasket.
To assure the IP65 and NEMA 4 protection, insert the panel
gasket between the instrument and the panel as shown in fig.

1.
While holding the instrument against the panel proceed as
follows:

1) insert the gasket in the instrument case;

2) insert the instrument in the panel cutout;

3) pushing the instrument against the panel;

4) insert the mounting brackets as shown in fig.1;

5) with a screwdriver, turn the screws with a torque between 0.3
and 0.4 Nm.

1) To avoid electrical shock, connect power line at the end of
the wiring procedure.

2) For power connections use No 16 AWG or larger wires rated for
at last 75 °C.

3) Use copper conductors only.

4) Don’t run input wires together with power cables.

For all relay outputs, the number of operations is 1 x 105 at
specified rating.
All relay contacts are protected by varistor against inductive load
with inductive component up to 0.5 A.

The following recommendations avoid serious problems which
may occur, when using relay output for driving inductive loads.

High voltage transients may occur switching inductive loads.
Through the internal contacts these transients may introduce
disturbances which can affect the performance of the
instrument.
For all the outputs, the internal protection (varistor) assures a
correct protection up to 0.5 A of inductive component.

a) The ” A ” terminal of the generator shall be negative with
respect to the ” B ” terminal for a binary 1 (MARK or OFF) state.

3) The EIA standard establishes that by RS-485 interface it is
possible to connect up to 30 devices with one remote master
unit.
The serial interface of these instruments is based on “High
input impedance” transceivers; this solution allows you to
connect up to 127 devices (based on the same transceiver
type) with one remote master unit.

NOTESNOTES

NOTES:

NOTESNOTES

1) Before connecting the instrument to the power line, make sure
that line voltage corresponds to the description on the identifi­cation label.

2) To avoid electrical shock, connect power line at the end of the
wiring procedure.

3) For supply connections use No 16 AWG or larger wires rated for
at last 75 °C.

4) Use copper conductors only.

5) Don’t run input wires together with power cables.

6) For 24 V DC the polarity is a not care condition.

7) The power supply input is fuse protected by a sub miniature
fuse rated T, 1A, 250 V.
When fuse is damaged, it is advisable to verify the power supply
circuit, so that it is necessary to send back the instrument to
your supplier.

8) The safety requirements for Permanently Connected
Equipment say:

- a switch or circuit-breaker shall be included in the building

installation;

- it shall be in close proximity to the equipment and within

easy reach of the operator;

- it shall be marked as the disconnecting device for the

equipment.

NOTENOTE

NOTE: a single switch or circuit-breaker can drive more than

NOTENOTE
one instrument.

9) When a neutral line is present please connect it to the 32
terminal.

This instrument can use the "IN CT" input or the "Feedback"
input; the two inputs are not contemporarily.
The current transformer input allows you to measure and
display the current running in a load driven by a time propor­tional control output during the ON and OFF periods of the
output cycle time. By this feature it is also available the "Out
failure detection" function (see page 111).
The feedback input is used when the servomotor close loop or
the servomotor open loop with valve position indication outputs
is required.

The instrument parameters are divided in two families and each
family is divided in groups.

- The first family encompasses all the run time parameters.

- The second family comprises all the configuration param­eters.

A specific security code enables the parameter modification of
each family.
For run time parameters, it is possible to select which groups of
them will be protected by the security code and in this case, it
is necessary to set the run time security code before to modify
one or more parameters of a protected group.
The configuration security code protects all configuration
parameters and it will be necessary to set the configuration
security code before to start the configuration parameters
modification.
For configuration parameters an hardware lock is also
available.
