If the reset is supposed to be controlled by the PC or another external trigger and not the buffer module, the
following wiring option is possible but requires an external relay:

Activation of the “external control mode”:

The PC-Mode pins need to be connected together during a normal mode operation. This connection must be opened
within the first second of a buffer event to set the buffer module into the “external control mode”. In this mode, a
signal on the inhibit input will not immediately execute a shut-down of the buffer module’s output but will be
delayed by 70s. The output of the buffer module will always be switched off for at least 5s.
