The LED near the relay connector indicates the control signal for the relay.
Connection of the reference switches and emergency stop buttons
The reference switches can be connected to the socket below the micropod and an
emergency stop button must be connected.
The reference switches and the emergency stop button are connected to ground (GND) and
are closed in the idle state. So in an emergency, you can also detect a broken cable.In
addition to mechanical limit switches, inductive limit switches of type NPN can also be
connected. The power supply is provided via the terminals 0V and 12V.

Attention!
The emergency stop button is not the only safety feature. Depending on the
hazard potential of the machine, additional safety measures may be required, such as door
interlocks and standstill monitoring. As a rule, such safety functions must
be implemented purely electromechanically with external circuits (not
included in the scope of delivery) and must not depend solely on
software and PC hardware. The system manufacturer, who assembles
the interface board and other components to form the overall system,
and the system operator are responsible for compliance with the legal
regulations.
Relay 1
Unfortunately, relay1 is connected incorrectly and is energized when the machine is
deactivated and the emergency stop circuit is activated. It cannot therefore be used to switch
a spindle, as it can tighten/drop uncontrollably in the event of an emergency stop or when the
control is switched on.
