NOTE:
If Controller type is set to ‘OFF’ (Refer page 32 for
Controller settings), the ‘Relay A/Relay B Setting’ is not
available.
The SP1 settings determine the operating parameters for Relay A; while
SP2 settings define the operating parameters for Relay B. Since these
two settings have identical setup parameters, only SP1 is described here.
The pH Controller allows you to configure two independent sets of
operating parameters for each relay (Relay A & B) for each
measurement mode (pH & ORP). However, when you switch
measurement modes, the relay operating parameters will be reset
automatically to their default values for that particular measurement
mode.
