If one safety input switches from high to low, while the other safety input remains high,
an unequal status is displayed:
Input LED flashes yellow
}
If this safety input switches back from low to high, while the other safety input remains
high, a feasibility error is displayed and a partial operation lock is triggered:
Input LED
flashes yellow
A switch to a high signal will only lead to normal switch operation if both inputs had a low
signal. From this moment on, the switch to high may occur (partial operation lock see
Error

).
DANGER!
Risk of sparking due to electrostatic charging of the safety switch in the po-
tentially explosive area
In order to avoid electrostatic charging, clean the safety switch with a damp
cloth.
Do not expose the safety switch to high charge-generating processes.
DANGER!
Risk of damage due to mechanical load. Live components on the safety
switch in the potentially explosive area may become exposed
Protect the edges of the safety switch base from shock. This can be
achieved by full face installation, for example (see
Installation [
39]
).
Protect the plug-in connector on the safety switch from shock.
Please note the information given in the "Installation" section.
