* When setting up the controller for the first time or after a full
reset back to factory default has been performed, the system
will electronically override the Safety Inputs and allow the
system to function without the links.
However, if safeties are connected to either or both inputs
thereafter, there must be a normally-closed circuit maintained
for the system to operate correctly.
i.e. if beams are fitted and then removed, the circuit which is
affected must be replaced with a wire link to create the normally
closed circuit.
Safe Common
Used for
switching the power supply to the safety beams
. If
automatic beam testing is required, the negative power supply
connection of the beam transmitter only must be wired to this point. In
addition, the beam test circuit must be switched on via Menu 6. See
Section 21.
Light/light
Pillar light connection
. These two terminals provide a normally open
potential-free contact which is generally used to switch on a pillar light
(courtesy light). This contact is fuse protected – refer to Section 3 for
fuse specifications.
