CONSTRUCTION
The plastic material made enclosure protects the control from
possible damages depending on crashes, openings, dust deposit,
contact with outside ambient.
Two LEDs of different colour, GREEN for power on and RED
for flame on, fitted on the upper side of the enclosure, permit an
immediate identification of the state of burner and control; a
version without signalling LEDs is also available.
DIRECTIONS FOR INSTALLATION
Connect and disconnect the control only with supplyoff.
The control can be assembled in everyposition.
Avoid exposure to dripping water.
Ventilation with the lowest temperature ensures the longest life
of thecontrol.
Make sure that you are using the correct type and code before
installing or replacing the control.
ELECTRICAL INSTALLATION
Every contact must be protected with a fuse of the fast blow
type suitable to the loadsconnected;
Before starting the control, check cables and connections
carefully (see Fig.5). Wrong connections can damage the
control and compromise the safety of theapplication;
A suitable degree of protection must beguaranteed;
The relevant electrical safety standards must be respected.
Fig.6
Fig.7 shows the diagram suitable to the installation of a
semiautomatic system for gas burners. For the flame detection,
both an ionization electrode or a phototube can be used.
Acting on the manual start button PM (with two contacts normally
open) supply is given to the TR ignition transformer and the EV 1
gas valve; the manual pressure on the button must be kept until
the flame is built and stable.

By releasing the button PM, the ignition transformer is turned off
and the operation continues until one of the following situations
occurs:
-
action on the manual stop button PA;
-
intervention of the thermostatT;
-
flame failure.
In any situation, the operation can be reset only by manual
intervention on start button PM.
In the same picture is also represented a duty example of the
second available contact, to detect the flame in distance.

detector with the control box for automatic gas burners, model
CM391 belonging to the EUROBOX series
CHECKING AT START
lways check the control before the first start and also after a long
period of system off. Before any ignition attempt make sure that
the combustion chamber is free from gas. Then check that the
level of the flame signal is sufficient (see Fig.6a and 6b for the
measuring).
