12 9900-1BC Batch Controller Manual

ERROR – Error:

If using S

L ﬂ ow 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 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.
