IMPORTANT NOTE
The bag dropper is set to run in Fail-Safe Mode and
therefore will prevent the operation of the Metalarm
when the bag is not present. This is indi cated by the
“Detect” light being illuminated.
It is vital that the conveyor is wired to stop when metal
is detected, otherwise the bag stem may enter the
equipment being protected. Although aluminum alloy
has been used in its construction, it would still mean
replacement of a relatively expensive part.
For any further information, please do not hesitate to
contact ERIEZ customer service.
Installation
(cont.)
Electrical
Connections
The standard electrical connections are for power
supply connections and for sensor coil connections.
Other cables may be added as necessary for control
and monitoring functions.
Please note where armored cables are being used,
the armor must be cut back at the gland plate of the
control unit so that it does not touch the Metal Detector
Control Unit. The control unit must be
electrically isolated.
POWER SUPPLY
The mains connection is made via the green terminal
block (TB1) using ‘E’ for earth/ground connection,
either of the ‘L’ terminals for live positive connection
and either of the ‘N’ terminals for live
negative connection.
The spare ‘L’, ‘N’ and ‘E’ terminals can be used for
driving external controls or the bag dropper accessory.
