pump will be allowed to run during the “enabled”
period when the level in the controlled lake calls for
the pump to run. If no level control is also
configured, the pump will run after the start time
and for the duration specified. Setting up the timed
operation will be described in detail below.

Start and Stop delays apply to level control and are
used to de-bounce, or account for wave action on
the probes or transducer signal.

Selecting a transducer tells the system to use the
transducer signal for level control rather than level
probes/floats.

Well/Txfr allows you to set up the pump as Well or
Transfer (Well pumps “Pump up” while Transfer
pumps “Pump Down”, though this distinction only
truly matters when using the transducer for level
control, both modes require a signal-on to run when
using probes for control).

Fbk selects whether the pump will provide a
feedback (pump running confirmation) to the PLC.
If selected, a pump fault will be reported if the pump
does not provide this feedback signal when called
to run. If not selected, the PLC will assume the
pump is running any time it is called for.

Fault Enables select whether to enable faults for the
well/transfer/timed pumps. LL enables Low Level
Safety, HPT enables the High Pump Temp safety,
and Seal enables the Seal Failure safety. HPT and
Seal are typically for submersible sump-type
pumps while Low Level safety is typically used for
turbine or submersible turbine type pumps.

CONFIGURING TIMED PUMPS:

Touch the pump image of any pump configured for
timed operation to open the Run Time configuration
screen.

Timed pump control consists of a Day to Enable,
Start time and Duration. The start day, time and
duration are taken together to determine if the
pump is in an allowable period to run. If the current
time is greater than the time period defined by Start
time and day, and less than start time and day, plus
duration, then the pump will be allowed to run.
Note that this means it is possible for a pump to run
on a day that is not selected if the previous days
duration setting extends past midnight.

Figure 38: Integrated Timed Pump configuration

For example, assume the pump is configured as
shown above. If the current time is Monday-Friday,
between 2:00 AM and 6:30 AM, the city fill valve will
be open if the probes for #8 Pond call for it. Any
other time the controls will ignore the probes and
the valve will remain closed.

If the setting were configured for 10:00 PM and the
duration was set for 4:00 hors, the pump could run
starting at 10:00 PM Monday-Friday, and would be
allowed to run until 2:00 AM the following morning
(even Saturday morning) but would not start
Saturday or Sunday evening (and would thus not
run Monday morning from midnight to 2:00 AM).

Lake Level Controls Setup (Non-Integrated only)
This screen allows you to enter the delay times for
the pump to start and stop after a specified level
has been reached. Time to Fault (sec) is the time
delay for system to issue a fault after a fault occurs.

Tap [Lvl Setup] to enter the start and stop levels
(feet) for up to 5 pumps in a popover screen.
Specify the type of pump using the radio buttons.

A well pump starts when the well water level falls
below the start level, and stops when the water
level is above the start level.

A transfer pump starts when the water level in the
tank is above the start level, and stops when the
level falls below the stop level.

Tap [Next] to move to the next Auxiliary Setup
screen.
