The Relays
Menus
The RELAYS menu contains the setup menus for programming, viewing,
and testing the instrument’s relay parameters. The relays may be used for
functions such as alarm, pump control, etc. Up to four relays may be
independently programmed for a variety of on/off conditions.
Alternatively, the relay can send a pulse to a remote device (for example, a
totalizer, sampler, or chlorinator) whenever the internal totalizer advances
by one unit.
