9.2.5.2 "Fault indicating relay" output (identity code 1)
A fault indicating relay can be ordered as an option - refer to ordering
information in the appendix. It is used to emit a signal when there is a fault
with the pump and for the "Liquid level low, 1st stage" warning message
and "Liquid level low, 2nd stage" fault message.
