3.1 Device overview

The S400, S410 and S420 safety hinge switches are very compact and stable electro-mechanical
switching devices in a housing made of metal (stainless steel for the S420); the devices satisfy protection
rating IP 67 and IP 69K. The actuator is integrated into the housing. Depending on the version, electrical
connection is done either via a cable or a M12 plug with optional cable entry from above, below or on the
wall side (mounting side). This enables monitoring of all types of doors, hoods, flaps, etc. The opening
angle of the safety hinge switch is up to 180°. The switching angle is adjustable and can be adjusted
multiple times if necessary (e.g. misadjusted door).

S400, S410 and S420 safety hinge switches are used as a mechanical hinges and simultaneously for posi-
tion monitoring of turning, bearing-mounted guards. The integrated safety contacts are force-opened as
soon as the preset switching angle is reached. As a result, the machine can only be switched on if the
protective device is closed.

In all models, the switching angle can be reset multiple times (e.g. when the door is misaligned) via the
protected adjusting screw. The covered screw mounting has a strong manipulation-resistant effect.

The S420 series satisfies strict requirements, e.g. in the food, pharmaceutical and cosmetic industries,
thanks to the stainless steel housing in accordance with safety class IP 67 and IP 69K with mechanical
load values up to 2000 N.

For the S420 series, versions are contact-supported or available with electronic inputs and OSSDs.

a) 2 input signals are present

b) irrelevant

Hinge switches of the S420 series with integrated OSSDs independently monitor the fulfillment of the input
condition and the redundancy of the actuator monitoring.

If one of the input signals is switched off, the S420-OSx switches both OSSDs off. Before activating the
OSSDs again, both input signals must be switched off and then reactivated.

In the event of very slow or minimal partial opening of the actuator, the S420-OSx switches both OSSDs
off. Before activating the OSSDs again, the actuator must be opened completely and then shut again.

In the event of fundamental errors (e.g. short circuit of the OSSDs) the diagnosis LEDs illuminate or blink
red. After trouble shooting and the following reset (switch-off of supply voltage), the S420-OSx switches
back to the normal operating mode.
