B – 3.5: No Flow Alarm
This is displayed when the controller does not
detect a flow signal. This alarm disables all
chemical feeds.
B – 3.6: Flow Restored Delay
This is displayed when flow is disrupted and then
restored. The BECSys3 will delay restarting feeds
for a programmed duration in order to prevent
operating feeds based on readings from stagnant
water.
B – 3.7: Cl/Br Lockout
This is 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 – 3.8: pH Failsafe
This is 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 – 3.9: Cl/Br Failsafe
This is 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 input reaches the
programmed set point.
2) Disruption of flow
3) User manually resets the failsafe.
B – 3.10: Booster FAILSAFE
This is 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 – 4: Resetting a Failsafe Alarm
