ERROR – Error:
If using S
3
L flow sensor, activates relay when no
sensor is detected.
MULTIPLE – Multiple Mode:
Activates relay when any one of the four enabled
conditions are met. User can select from Missing
Signal, Overrun, High Flow or Error.
TOT VOL – Totalizer Volume:
When resettable totalizer exceeds specified volume,
relay activates and latches.
Requires Totalizer Volume Reset to deactivate relay
(see Reset Total,
page 18).
This mode is useful to trigger a reminder when a
process is due, as for a backwash cycle or filter
change.
TWO STG – Two Stage:
This function is designed to prevent overfilling or
to minimize water hammer. Both the mainline relay
and the bypass relay are energized when the batch
starts. The mainline relay then de-energizes at a
programmed batch percentage, allowing flow to
continue through a smaller bypass line to reduce the
fill rate (see diagram). After the batch is dispensed,
the bypass relay de-energizes, completing the
sequence.
NOTE:
If Relay 1 is selected for Two-Stage operation,
relay 2 defaults to Bypass. If Relay 2 is selected,
relay 3 defaults to bypass. If Relay 3 is selected,
relay 2 defaults to bypass.
