Notes

Line fault detection at the On pushbutton:

The output contacts cannot be closed if the On pushbutton is already

closed before the voltage is applied to S12, S22 (also in the event of a line

fault at the On pushbutton).

A line fault at the On pushbutton which occurs after activation of the de-

vice is recognized when switching- on takes place again and closing of the

output contacts is then prevented.
If a line fault occurs at the On pushbutton after the voltage is already
present at S12, S22 undesired activation will take place, because this line
fault does not differ from the normal closing function.
The gold-plated contacts of the BD 5987 mean that this module is also
suitable for switching small loads of 1 mVA ... 7 VA, 1 mW ... 7 W in the
range 0.1 ... 60 V, 1 ... 300 mA. The contacts also permit the maximum
switching current. However, since the gold plating will be burnt off at this
current level, the device is no longer suitable for switching small loads
after this.
The PE terminal permits operation of the device in IT systems with insula-
tion monitoring and also serves as a reference point for testing the control
voltage. The internal short-circuit protection will be bridged on DC devices,
if the protective ground is connected to terminal PE.
One or more extension modules BN 5989 or external contactors with for-
cibly guided contacts may be used to multiply the number of contacts of
the emergency stop module BD 5987.
For automatic restart:
S22 must be connected before S12. S12 initiates the automatic restart.
With manual restart it is not necessary to follow this order.
