Relay Mode Settings
TOT VOL – Totalizer Volume:
When resettable totalizer exceeds
specifi ed volume, relay activates and
latches.
Requires Totalizer Volume Reset to
deactivate relay (see Reset Total, pg. 16).
This mode is useful to trigger a reminder
when a process is due, as for a
backwash cycle or fi lter change.
TWO STG – Two Stage:
This function is designed to prevent
overfi lling 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 fl ow to continue
through a smaller bypass line to reduce
the fi ll 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.
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.
ERROR – Error:
If using S L fl ow sensor, activates relay
3
when no sensor is detected.
