PRECAUTIONS
The instrument has been
designed to work in an harsh
and noisy environmental (level IV
of the industrial standard IEC
801-4). It is recommended to
follow the following suggestions.
A
All the wiring must comply
with the local regulations.
The supply wiring should be
routed away from the power
cables. Avoid to place electromagnetic contactors, power
relays and high power motors
nearby. Avoid power units in
close proximity, especially if
controlled in phase angle mode.
Keep the low level sensor
input wires away from the
power lines and the output
wiring. If this is not achievable, use shielded cables on
the sensor input, with the
shield connected to ground.

Notes:
1] Ensure that the power supply voltage is
the same as that on the instrument label.
2] Switch ON the power supply only after
all electrical connections have been
completed.
3] In accordance with electrical safety reg-
ulations, there must be an easly identifiable and accessable power disconnect.
4] The instrument is PTC protected.
In case of failure, return the instrument to
the manufacturer for repair.
5] To protect internal circuits use:
- 2 A
~ T fuse for Relay outputs (220 Vac)
- 4 A~ T fuse for Relay outputs (110 Vac)
- 1 A~ T fuse for Triac outputs
6] Relay contacts are protected with varis-
tors.
In case of 24 Vac inductive loads, use
model A51-065-30D7 varistors (on
request).

• Low Voltage version:
Nominal voltage:
24Vac (-25...+12%);
Frequency 50/60Hz
or 24Vdc (-15...+25%);
Power consumption 5W max.
A L-J-K-S-R-T-B-N-E-W thermocouple type
• Connect wires with the polarity as shown;
• Always use compensation cable of the correct type
for the thermocouple used;
• The shield, if present, must be connected to ground.
B For Pt100 resistance thermometer
• If a 3 wires system is used, always use cables of the
same section (1mm2min.), maximum line resistance
20 Ω/line.
• When using a 2 wires system, always use cables of the
same section (1.5mm2min.) and put a jumper between
terminals 11 and 12
C For ∆T (2x RTD Pt100) Special
A When the distance between the controller and the
sensor is 15m, using a cable of 1.5mm2 section, produces an error on the measure of 1°C.
R1 + R2 must be <320Ω
