Function: During bridging, the ULVT safety light barrier can be
interrupted without the alarm being activated and/or the entire
system being switched off.
Bridging continues for as long as either the contacts of the two
muting sensors LS 1A and LS 2A or LS 1B and LS 2B, or all
four, are closed.
If the ULVT safety light barrier is interrupted and not bridged at
the same time by the muting sensors, the alarm is activated via
contact B-11 (potential-free break contact) and the system
switched off via the output contacts 20-21 and 16-17. This
enables differentiation between man and material flow.
A restart and deactivation of the alarm is possible by pressing
the start button when the ULVT safety light barrier is free.
Before pressing the key start button, it must be
ensured that no person is located within the
hazardous area.
For safety reasons, the minus and plus lines
must be routed as shown in the connection
diagram. The cabling for muting channels 1 (LS
1A/B) and 2 (LS 2A/B) must be implemented
separately.

Cable routing: Separately
from power lines. The cable
routing for the contactor
check (terminals D & 22)
must prevent short-circuiting
of wires.
If the sum of the currents to
terminals B, 10, 17 & 21
exceeds 2A, separate fuse
protection of M 2.0 A must
be provided for the contacts.
The hazardous movement
must only be activated via
output contacts 16-17 and
20-21.
The output contacts are
potential-free, monitored,
guided make contacts are
must be loaded with max. 2
A/250 VAC or 60 VDC, 30
W.
With inductive load, the load
(not the contacts) is to be
switched at the same time
as the spark arresting
sections (e.g. 0.22 uF,
220
Ω
.
The contact B-11 serves as
an alarm path and is not
permitted to activate the
hazardous closing
movement.
When performing electric
welding work on the
machine, the terminal strip
of the switchgear is to be
removed, otherwise the
vagrant welding currents
may cause destruction of
the installed electronics.
