9.2.6.2 "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.
The fault indicating relay can be retrofitted and is operational once
attached to the relay board - refer to "Retrofitting relays" supplementary
operating instructions.
