free. Check the status of the displays on the receivers. Check
whether all transmitters are lit up. Eliminate any dirt spotsIf
necessary, readjust the transmitter and receiver. Check the
installation.
Activate the test or turn the voltage supply off and back on again.
If the error occurs continuously, there is an internal error present.
Send the SC2 control system in for repairs.
Check the DIP switch setting
Check the installation of the relay monitor (are the feedback con-
tacts normally open contacts?). If the system is supposed to work
without a relay monitor, turn off the corresponding DIP switches.
Check the cable between SC2 and the light barriers (transmitter
and receiver)
