OUTPUT
21 connections are available for 6.35 mm faston terminals.
Signal inputs
Inputs from TC or RTD (2 wires) are attached to faston 1 (positive)
and 3 (negative). (Short circuit 3 and 4 for RTD with 2 wires).
For RTD with 3 wires, the single wire is attached to faston 1;
for the remaining wires, one goes to faston 3 and the other to
4.
Input from current transformer (HB function)
If the instrument accepts this input, the signal must be attached to
faston 6 and 7; Secondary current input for CT, impedance 20mΩ,
5A, 50/60Hz.
Power supply
Voltage (100...240Vac) is attached to fastons or terminals 12 and
14. A version with 11...27Vac/dc voltages is available.

Hardware protection
To remove the electronic part of the case, loosen the front screw until release, then remove by hand. Configuration is performed on the
input board, the output/power board, and on the optional board.

Introduction
Work mode lets you monitor the main process quantities: process
variable, load current, control output power, while output state
(MAIN and alarms) is signaled by their LEDs. It also lets you
display and set the setpoints and alarms.
You can scroll the seven work processes (see table below) by
means of the F key.
Use the Raise and Lower keys to set the setpoints and alarms. .
Confirm the set value by pressing the F key, if the key is not
pressed, the value will be confirmed automatically 10 seconds after
the last change.
Enabling the various phases depends on the hardware and
software configuration and on the software protection level that is
set (Pro code in CFG.2 procedure). In minimum configuration, only

Logic output type D2 24V is available to fastons 16 (positive) and
15 (negative). Continuous output to terminals or fastons 19 (+)
and 17 (-) as alternate to relay output.
Alarm outputs
For alarm relays: terminals or fastons 20 (N.C.) 21 (C) and 22
(N.O) for alarm 1; terminal faston11 and 10 (N.C. o N.O.) for alarm
2; terminals 9 and 8 (N.C. o N.O.) for alarm 3/HB.
NC contacts are available for alarms 2 and 3 by changing the
jumpers. Contact capacity is 5A for alarms 1, 2 and 3.
Digital communication (Current loop / 485)
If the instrument accepts a 1200 baud Passive Current Loop
interface, the reception diode is available at fastons 8 (Rx+) and 9
(rx-); transmission transistor to fastons 10 (Tx+) and 11 (tx-).
In standard configuration for parallel connection on the serial line,
the resistance in series to the diode is 1K Ohm; 100 Ohm to the
transistor collector.
For the series connection, the resistance in series to the diode
is 100 Ohm. If the instrument accepts 1200...9600 baud 4-wire
RS485 interface, reception is available to fastons 8 (Rx+) and 9
(Rx-); transmission to fastons 10 (Tx+) and 11 (Tx-).
(See hardware configuration in Appendix).

Messaggi di errore e segnalazioni
Power on
phases 0 and 1 are available.
At power-on, after the display has finished flashing, the instrument
goes to work mode phase 0 (automatic start), or to phase 6
(manual start).
Specific combinations of keys let you switch between automatic
and manual, turn the software off and on, start or interrupt self-
tuning.
Work mode is the starting point for access to Programming,
Configuration and Calibration phases.
