Proper Use
The devices are safety switching devices. They must only be used as components of safety equipment on machines intended to protect persons, material and
plant.
Notes
The Performance Level (PL) and safety category in accordance with EN ISO 13849-1 depends on the external wiring, the application case, the choice of
control station and how this is physically arranged on the machine.
The user must carry out a risk assessment in accordance with ISO 14121-1.
The entire system/machine must undergo validation in accordance with the applicable standards on the basis of this.
In order for the specified Performance Level (PL) to be achieved, an average annual number of switching cycles must not be exceeded (see EN ISO
13849-1, C.2.4 and Tab. K.1), taking into account the prevailing device load (see EN ISO 13849-1, Tab. C.1) and the application case. Assuming that the
B
value for the maximum load is 400,000, this results in a maximum cycle number of 400,000 / 0.1 x 30 = 133,333 switching cycles/year.
10d
Operating the device not within the specifications may lead to malfunctions or the destruction of the device.
Operate the RESET button not longer than 3 s. The indicated times must be observed when the device is operated, otherwise the device could
lock. Locking can be cancelled by opening the safety inputs properly.
SNE expansion devices or external contactors with positively driven contacts can be used to duplicate the enabling current paths.
The device and the contacts must be protected at max. 6 A utilization category gG.
The devices are equipped with overload protection (for short-circuit). After the malfunction has been dealt with, the device is operational
again in approx. 3 s.
Control outputs S11/S13 is exclusively for connecting control devices as defined in the operating instructions and not for connecting external
consumers such as lamps, relays or contactors.
Close the E-Stop circuit before operate the RESET button.
If sensors with reed contacts or semiconductor outputs used pay attention to the peak current (see technical data section control circuits).
