Operation and Maintenance Manual
Rev: L13
A – 5.13: Polymer
If your controller is configured to control a
Polymer feed, you will have the following options:
High Set Point (Op):
Only shown if control type is
set to Turbidity Control.
When the turbidity reading
rises above this value for the Trigger Delay Time,
the controller will trigger the polymer control
cycle.
Low Set Point (Op):
Only shown if control type is set
to Turbidity Control.
At the end of each control
cycle, the controller checks to see if the turbidity
reading is below this value. If it is, the control
cycle ends, otherwise the controller starts a new
control cycle.
Cycle Time (Op):
Only shown if control type is set to
Turbidity Control.
This value sets the control cycle
duration. At the beginning of each cycle, the relay
turns on, stays on for the programmed On Time,
then shuts off for the remainder of the cycle time.
On Time (Op):
Only shown if control type is set to
Turbidity Control.
This value sets how long the
controller will feed polymer during each control
cycle.
Trigger Delay Time (Op):
Only shown if control
type is set to Turbidity Control.
This value sets how
long the turbidity reading must remain above the
high set point before triggering the polymer
control cycle.
Start/End Time (Op):
Only shown if control type is
set to Cycle Timer.
Allows you to set what times the
feed may be triggered during a day.
# Of Cycles (Op):
Only shown if control type is set to
Cycle Timer.
Sets how many times the feed will be
triggered between the Start and End times.
Duration (Op):
Only shown if control type is set to
Cycle Timer.
Sets how long the feed will run for
each cycle.
A – 5.14: Recirculation Pump
If your controller is configured to control the
Recirculation Pump, you will have the following
options:
Pres. Alarm Delay (Op):
Delay pressure and
vacuum alarms from triggering for this amount of
time whenever the recirc pump starts up.
Heater Fireman Switch (Op):
This option is only
shown if a relay is assigned to the Heater control.
This
value sets the minimum amount of time to leave
the recirculation pump on or delay the start of
backwash after the heater shuts off.
Ozone Fireman Switch (Op):
This option is only
shown if a relay is assigned to the Ozone control.
This
value sets the minimum amount of time to leave
the recirculation pump on or delay the start of
backwash after the Ozone relay shuts off.
UV Turndown Fireman Switch (Op):
This
option is only shown if a relay is assigned to the UV
Turndown.
This value sets the minimum amount of
time to leave the recirculation pump on or delay
the start of backwash after the UV turndown relay
turns on.
A – 5.9.1: VFD Control:
Allows you to configure the VFD control settings
for the Recirculation Pump. Once you have
selected VFD Control you will have the following
items to choose from:
OOR alarm delay (Op):
This option is only
shown if the Control Input is set to Flow Meter.
If the
output required to meet the set point exceeds
100%, the triggering of the Out Of Range
(OOR) alarm will be delayed by this amount of
time. Set to 0 to disable the alarm.
Set Point (Op):
Allows you to set the value to
control to. (in % or flow rate depending on
what the control input is set to).
Dead Band (View Only):
This option is only
shown if the Control Input is set to Flow Rate.
The
VFD output will not change until the input is
this far away from the set point.
Backwash Output (View Only):
This option is
only shown if the backwash control is configured.
Sets
the VFD percent output to use when
backwashing.
Minimum Output (View Only):
The
controller will always keep the VFD output
above this % except when the relay is off.
A – 5.15: Alarm Relay
There are no programmable options for the Alarm
Relay. Whenever there is an alarm or Emergency
Off is active, this relay will turn on.
