Notes

If the ON pushbutton was already closed before the voltage was applied at
S12, S22 (also in the case of line fault via the ON pushbutton), the output
contacts cannot be switched on.
A line fault at the ON pushbutton which occured after activation of the unit
is recognized when switching on takes place again and switching-on of the
output contacts is prevented. If a line fault occurs at the ON pushbutton
after the voltage has already been applied at S12 and S22, unwanted
activation occures because this line fault can not be distinguished from the
regular switching-on function. The PE testing terminal allows the units to
be also operated in IT networks with insulation monitoring. It also serves
as a reference point for checking the control voltage and as a connection
contact in the event of an emergency-stop with cross fault detection.
Because of the gold-plated contacts the BD 5935 can be used to switch
small loads 1 mVA ... 7 VA, 1 mW ... 7 W in the range of 0.1 ... 60 V,
1 ... 300 mA. The gold-plated contacts allow also to switch the maximum
current but the gold plating will be burnt off. After that the contacts cannot
be used any more to switch the small loads.
One or more extension modules BN 3081 or external contactors with
forcibly guided contacts can be used to multiply the number of contacts
of the emergency-stop module BD 5935.
The switches S1 and S2 are provided for the following selection possibilities:
Automatic-start, manual-start and emergency-stop with or without cross
fault detection. These switches are located behind the front cover panel
(see unit programming diagrams).
Switch S2 is for selecting automatic or manual Start. In addition, terminals
S33 and S34 must be jumpered for "automatic start function".
Selection of the operating mode with or without cross fault detection at
the emergency-stop pushbutton is performed via the switch S1. The unit
must be connected as shown in the application example.
