WARNING!
To guarantee safety, the mechanical arrangement of the gate
switches must comply with the requirements of EN 1088
“Interlocking devices associated with guards”. If these
requirements are not met, the safety of the guard will be lost,
which may lead to
serious injury and death !
The following example shows the arrangement of two
mechanical gate switches. In this case, one of the switches (on
the left in this example) must have a N/O contact which is
actuated by the gate in positive mode, while the other switch
(on the right in this example) should have a N/C contact which
is actuated by the gate in non-positive mode.
Fig. 6-5: Mechanical arrangement of the gate switches
• LCKD: Guard locking monitoring circuit: Gate locked
LCKD = 0: Gate unlocked
LCKD = 1: Gate locked
• SyTi: Synchronisation time between S1 and S2
Permitted value range: 0 ... 32767
Time unit: ms
SyTi = 0: The synchronisation time is infinite, i.e. monitoring is
switched off
SyTi < 0 Synchronisation time monitoring has no tolerance, i.e.
when the gate closes, the signals on the gate switches must
supply a 1-signal simultaneously (i.e. within one PSS cycle),
otherwise an error message will occur.
