Gating restart and override
In the event of an error in the gating sequence (e.g.: timeout, failure of the supply voltage, sequence error,
etc.), the gating function can be triggered manually and the system started even with light axes of the
safety sensor interrupted. Interfering objects can thereby again be cleared. A CS switching signal must be
present. In operating modes 1 and 6, the antivalent TH timer hold signal is to be applied in addition to the
CS switching signal.
WARNING
Premature unlocking of the start/restart interlock may result in serious injury!
If the start/restart interlock is unlocked, the system can start up automatically.
Ä
Before unlocking the start/restart interlock, make certain that the cause of locking (e.g., se-
quence error) has been rectified.
Ä
Before unlocking the start/restart interlock, make certain that no people are in the danger
zone.
Depending on whether or not the synchronization beams are occupied, a gating restart (see chapter 4.5.4
"Gating restart") or override (see chapter 4.5.5 "Override") is to be performed.
