Notes
If both buttons are pressed while switching on the operating voltage (e.g.
after voltage failure) the output contacts do not energize.
The terminal S22 also serves as reference point for checking the control
voltage.
On BG 5933 there is only one terminal S12 and S22.

Set-Up Instructions
The device has to be connected as shown in the application examples.
When connecting the push-buttons in parallel or in series the safe function
of the relay is disabled. Connected contactors (relays) must have forcibly
guided contacts and have to be monitored in the feedback circuit.
To start a dangerous movement, 2 push buttons are used, each equipped
with 1 NO and 1 NC contact. The output contacts will be switched if both
push buttons are operated within ≤ 0.5 s. The buttons must be designed
and installed in a way, that it is not possible to manipulate or to operate
them without intention.
The distance between push buttons and dangerous area must be chosen
in a way that it is not possible to reach the dangerous area after release
of one button before the dangerous movement comes to standstill.
The safety distance "s" is calculated with the following formula:
s = v x t + C
a)
moving speed of person v = 1 600 mm/s
b)
stopping time of the machine t (s)
c)
Additional safety distance C = 250 mm
If the risc of accessing the dangerous area is prohibited while the push
buttons are pressed e.g. by covering the buttons, C can be 0. The minimum
distance has to be in this case 100 mm. See also EN 574.
