Mounting note (SYNC function):
IMPORTANT:
When using two pairs of photocells please do not
install both photocell transmitters/receivers on the same side (to
eleminate interference between both) !
Exception:
photocells with SYNC function allow the installation of
both photocell transmitters/receivers on the same side without causing
interference to each other.
Self-monitoring of photocells:
The control unit has a monitoring function for the connected photocells. A test will be triggered by each impulse
and will be checked if the receiver of the photocell responds to the signal from the photocell transmitter. If the-
re is no communication between the photocell receiver and transmitter the control unit responds with an error.
The deactivation of the self-test function is only permitted if the safety installations correspond to the
category 3 !
Photocell function:
The exact function of the photocells depend on the programming of the control unit:
see menu point SAFETY / PHC/ISD function and SAFETY / PHC/ISD pause time (
page 14).
you will find detailed information in the corresponding photocell manual..
