Action
Check that all relays are powered up.
Check that all relays have unique addresses.
Check that the correct DC voltage is applied and that the polarity
is correct.
Check that the status input settings such as the pick-up and drop-
off timers and the status inversion function are correctly set.
This is normal. The relay is displaying calculation noise. This will
not affect any accuracy claims for the relay.
