Operation and Maintenance Manual Rev: C17
 Failsafe Timer (Op): This value sets the time
that the relay is allowed to stay on without
reaching set point before the relay is locked out. If
Autofill has been trying to achieve set point
without success for the selected time, the
controller will cut power to the relay, flash the
Reset Fail/Safe LED on the face panel and display
a message to alert the operator.
An operator must reset the failsafe through
the Reset Fail/safe button to re-enable normal
control.
A – 5.10: Bleed Valve
 Hi Surge Pit Bleed (Op): Only shown if the Surge
Pit 4-20mA sensor or the Surge Pit safety input is
installed. Enable or disable opening the bleed valve
on high surge alarm and/or high surge safety alarm
 TDS Control En (Op): Only shown if the conductivity
sensor is installed. Enable or disable using TDS to
control the bleed valve..
 Makeup water TDS (Op): Only shown if TDS
Control is enabled. Enter the test kit TDS reading
for the water controlled by your Autofill. This is
used to determine the appropriate TDS set point.
 Pool TDS cycle (Op): Only shown if TDS Control
is enabled. Enter the pools' cycle multiplier of the
incoming makeup water. The resulting TDS set
point is the incoming makeup water's TDS times
this value.
 Failsafe Timer (Op): Only shown if TDS Control is
enabled. This value sets the time that the relay is
allowed to stay on without reaching set point
before the relay is locked out. If the TDS control
has been trying to achieve set point without
success for the selected time, the controller will cut
power to the relay, flash the Reset Fail/Safe LED
on the face panel and display a message to alert the
operator.
An operator must reset the failsafe through
the Reset Fail/safe button to re-enable normal
control.
A – 5.11: Filter Backwash
If your controller is configured for filter control,
you will have the following options:
A – 5.11.1: Triggers
A – 5.11.1.1: Timer Setting:
 Enable Timer (Op): Enables or disables
triggering backwash from the 4 Event 28
Day Timer.
 4 Event 28 Day Timer (Op): Only shown if
the timer is enabled. The 4 Event 28 Day
Timer allows you to program a backwash
based on a schedule.
Selecting Event 1 will allow you to select the
weekly interval to trigger the backwash.
If the 1
st
, 2
nd
, 3
rd
, or 4
th
week is selected, the
timer will only trigger on that week in the
four-week cycle. The Odd Weeks selection
will trigger on the 1
st
and 3
rd
weeks, the Even
Weeks selection will trigger on the 2
nd
and 4
th
weeks, and the Every Week selection triggers
every week.
The week number and day of week for
the current date is displayed on the
bottom right side of these screens.
The first week is fixed to be the week of
Sunday, January 2
nd
, 2000 and every four
weeks afterward.
After making your selection, you can select
the day of the week (or every day) the
backwash should be triggered on.
Once you make your selection, you will be
returned to the 4 Event 28 Day Timer menu
where you will have a new menu item:
Event 1 Start Time.
Select the Event 1 Start Time from the 4
Event 28 Day Timer menu. This screen will
allow you to set the time to trigger the event
on the programmed week/days. The event
will trigger at the start time if the controller is
running at that time. To toggle AM/PM,
press the +/- Key. Enter the desired time
and press enter.
A – 5.11.1.2: Pressure Settings:
 Start BW Enable (Op): Enables or
disables triggering backwash from a high
differential pressure. If enabled and the
filter pressure type is set to transducer, the
controller allows you to set the triggering
differential set point. If the filter pressure
sensor type is set to contact switch, then the
controller will trigger a backwash when it
sees a contact closure on the input assigned
to be BW Diff. Pres Trig.
 Set Point (Op): Only shown if the Start BW
Enable is enabled and the filter pressure sensor types
are set to transducer. When the differential
pressure rises above this value for the BW
Start Delay, the controller will trigger a
backwash.
 BW Start Delay (Op): Only shown if the Start
BW Enable is enabled. This is the amount of
time the differential pressure must remain
above the Set Point before it triggers a
backwash.
