Operation of the relays (J15 and J19 connectors)
Ejector relay (Eject relay):
Programmable relay with delayed action (with respect to the detector alarm); capacity; the programming parameters that
relate to the functioning of this relay are ED, EM and ET (see Programming chapter).
Alarm relay
programmable relay with immediate action (with respect to the detector alarm); capacity; the programming parameter that
relates to the functioning of this relay is AT.
Malfunction relay (Fault relay)
Safety operation relay (contacts NA and C connected in correct operation); capacity; the programming parameter that
relates to the functioning of this relay is FR.
Malfunction conditions are described in the Maintenance section.
N.B.: when the device is switched on, the relay is not activated (malfunction condition) for about 6 seconds.
Upstream belt authorisation relay (Preceding conveyor relay)
Safety operation relay (contacts NA and C connected in correct operation); capacity 3A.
Auxiliary relay for signalling when periodic test is due (TEST LAMP relay)
Programmable relay ; 3A current-carrying capacity ; the programming parameters relating to operation of this relay are
LB and the parameters of the QA configuration menu (see Programming section).
Timing
Belt blocking with manual alarm reset (EM=B)
Operation with halting of the production line, manual elimination of the contaminated material and manual reset by the operator.
N.B.: The metal detector does not check if there are any subsequent fragments in the material immediately following: all material under the probe
must therefore be eliminated along with the part that caused the alarm. To minimise waste of material it is advisable to select a low setting for the
ED parameter.

Belt blocking with photocell synchronisation and manual alarm reset (EM=SB)
Operation with halting of the production line synchronised by photocell, manual elimination of the contaminated material and manual reset by the
operator. Allows precise positioning of the material to be rejected.
