navigating to the actual I/O-board and the binary input in question. The
activated output signal is indicated with a yellow-lit diode. Each
BOn_PO is represented by two signals. The first signal in LHMI is the
actual value 1 or 0 of the output, and in PCM600 a lit or dimmed diode.
The second signal is the status Normal or Forced. Forced status is only
achieved when the BO is set to
Forced
or operated on the LHMI.
Set the parameter
TestMode
to
Off
after completing these
tests. The Start LED will stop flashing when the relay is
no longer in test mode.
An initially high contact resistance will not cause problems as it will be reduced
quickly by the electrical cleaning effect of fritting and thermal destruction of
layers, bringing the contact resistance back to the mOhm range. As a result,
practically the full voltage is available at the load.
