FSK Test
This page will allow the user to force the carrier signal to different frequencies. This can be
useful in troubleshooting, tuning auxiliary coupling equipment or measuring levels etc. Forcing
the carrier will cause the PLC module to go into minor alarm. This reminds the user that the PLC
is not in its “normal” state.
CAUTION:
Leaving the carrier on a different frequency will affect the operation of the unit and protection of
the system.
Always put the carrier back into the normal state before leaving the unit.
