B - 4: Alarms
During normal operation, the following alarms may
be displayed.
Some alarms will not be available
depending on the system's configuration.
B - 4.1: pH High/Low alarms
Displayed when the pH input has risen
above/fallen below the pH high/low alarm point.
These alarms will also trigger the Cl/Br Lockout
alarm.
B - 4.2: ORP High/Low alarms
Displayed when the ORP input has risen
above/fallen below the ORP high/low alarm
point.
B - 4.3: No Flow alarm
Displayed when the flow input indicates the flow
has stopped.
This alarm disables all chemical
feeds.
B - 4.4: (x) min Feed Delay
When flow is disrupted and then restored, the
controller will delay restarting feeds for a
programmed duration in order to prevent
operating feeds based on readings from stagnant
water. (x) = the number of minutes remaining
before feeds are allowed to start (e.g. 5 min Feed
Delay).
B - 4.5: Cl/Br Lockout
Triggered whenever there is a pH high or low
alarm, this message indicates that the Cl/Br feed
(relay 2) and the optional Cl/Br Booster (relay 3)
are disabled in order to prevent the Cl/Br feeds
from driving the pH even further out of range.

B - 4.6: pH FAILSAFE ALM
Displayed when the active pH feed (feed up or
feed down) attempted to feed continuously for the
selected failsafe duration. The active pH feed is
disabled until one of the following conditions
occurs:
1) The pH input reaches the programmed set
point.
2) Disruption of flow
3) User manually resets the failsafe.
B - 4.7: Cl/Br FAILSAFE
Displayed when the Cl/Br feed attempted to feed
continuously for the selected failsafe duration.
The Cl/Br feed is disabled until one of the
following conditions occurs:
1) The
ORP/ppm
programmed set point.
2) Disruption of flow
3) User manually resets the failsafe.
B - 4.8: Booster FAILSAFE
Displayed when the optional Cl/Br Booster feed
attempted to feed continuously for the selected
failsafe duration.
The Cl/Br Booster feed is
disabled until one of the following conditions
occurs:
1) The ORP input reaches the Cl/Br Booster set
point.
2) Disruption of flow
3) User manually resets the failsafe.
B - 5: Resetting a Failsafe Alarm
To reset a failsafe alarm, press and hold the Up and
Down Arrow keys for two seconds.
