1. GENERAL ADVICES
•Please read t is manual before using
•T is manual is part of t e product and s ould be kept near t e
instrument for easy and quick reference.
•T e instrument s all not be used for purposes different from
t ose described ereunder. It cannot be used as a safety
device.
•C eck t e application limits before proceeding.
1.1 Safety Precaution
•C eck t e supply voltage is correct before connecting t e
instrument.
•Do not expose to water or moisture: use t e controller only
wit in t e operating limits avoiding sudden temperature
c anges wit ig atmosp eric umidity to prevent
formation of condensation
•Warning: disconnect all electrical connections before any
kind of maintenance.
•Fit t e probe w ere it is not accessible by t e End User. T e
instrument must not be opened.
•In case of failure or faulty operation send t e instrument
back to t e distributor or to “Dixell s.r.l.” (see address) wit a
detailed description of t e fault.
•Consider t e maximum current w ic can be applied to eac
relay (see Tec nical Data).
•Ensure t at t e wires for probes, loads and t e power supply
are separated and far enoug from eac ot er, wit out
crossing or intertwining.
•In case of applications in industrial environments, t e use of
mains filters (our mod. FT1) in parallel wit inductive loads
could be useful.
1.2 full Manual

17. ELECTRICAL WIRING
T e controller is provided wit removable terminal blocks for wires aving section not bigger t an 1.0 mm2:
14 ways for supplay, analogue inputs and digital inputs,
12 ways or 6 ways for relays (depending on model)
Note:
•terminals 17-19 are connected inside t e controller (common for t e “relay n°1” (terminal 15) and “relay n°2” (terminal 16))
•terminals 21-22 are connected inside t e controller (common for t e “relay n°3 ” (terminal 18) and “relay n°4” (terminal 20))
A 5-ways connector is dedicated to t e TTL / RS485 interface.
T e controller as 4 connectors (depending on model) for remote keyboard, open collector outputs, Pb4 probe, 4..20mA / 0..10Vcc
analogue output; t e connectors ave 2 ways (0.2 mm2 wires).
Remote keyboard is provided wit 2-ways screw terminal block for wires not bigger t an 2.5 mm2.
Check power supply data before connection wires.
Keep the probe and the digital input wires separate from the power cable.
Do not exceed t e maximum rating current for eac relay, c eck tec nical data and if t e load is bigger, use filtered contactors.
