1. GENERAL WARNING
1.1 Please read before using this manual
This manual is part of the product and should be kept near the instrument for easy and quick
reference.
The instrument shall not be used for purposes different from those described hereunder. It
cannot be used as a safety device.
Check the application limits before proceeding.
1.2 Safety Precautions
Check the supply voltage is correct before connecting the instrument.
Do not expose to water or moisture: use the controller only within the operating limits avoiding
sudden temperature changes with high atmospheric humidity to prevent formation of
condensation
Warning: disconnect all electrical connections before any kind of maintenance.
The instrument must not be opened.
In case of failure or faulty operation send the instrument back to the distributor or to “DIXELL
s.r.l.” (see address) with a detailed description of the fault.
Consider the maximum current which can be applied to each relay (see Technical Data).
Ensure that the wires for probes, loads and the power supply are separated and far enough
from each other, without crossing or intertwining.
Fit the probe where it is not accessible bythe end user.
In case of applications in industrial environments, the use of mains filters (our mod. FT1) in
parallel with inductive loads could be useful.
