Important
• if the SYNC-function is needed when connect
-
ing
two
photocells LS26
(see notes for photo
cells)
, then
the infrared frequency of both
transmitter-/receiver pairs the Jumper J
have to be adjusted in a different way.
Photocells
•
The control unit has a power supply connection for a 24V a.c. photocell (LS):
supply LS-transmitter: terminals 41/42 Note: in „closed“ position the terminals 41/42 are being switched
into energy saving mode (no current)
supply LS-receiver: terminals 43/44.
• The contact has to be closed when using powered and positioned photocells (opening contact).
Connection of the photocell contact: terminals 45/46
•
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.
Therefor the photocells LS25, LS31, LS40
are supplied
with necessary a.c. voltage by this control. The SYNC
function of LS26 works with adjustment of different infrared
frequencies
• Photocell self-test function:
The control board is equipped with a self-test function for the connected photocell. With an opening impulse (switch or
button) the transmitter of the photocell is switched off for a short time in barrier position „closed“ . Thus the photocell
receiver interrupts the contact 45/46 - so the control board verifies the function of the photocell receiver. If this short
interruption at the photocell input is not carried out, the control board reports an error.
The deactivation of the self-test
function is only allowed if the safety installations correspond to the category 3 !
• The exact function of the photocells depend on the programming of the control unit.
Photocell function please see
menu point SAFETY / photocell function or photocell with pause time (p. 18)
• You will find d
etailed information in the corresponding photocell manual.
