Figure 55: Lake Level Controls Setup
Up to 8 Well/Transfer/Timed pumps can be
controlled when using the integrated system. Set
the IP address of the lake Level Controls auxiliary
equipment to match the main PLC to enable the
integrated controls (Note: The IO mapping must be
configured for the Lakefill/Transfer/Timed pumps to
use the integrated system, consult the factory when
adding equipment to 5.0+ Pace systems).
The master Auto button must be enabled for any of
the level/timed pumps to run. Press “System Off” to
disable all Level/Timed pumps. (Pump station
operation is not affected).
Touch the pump name to configure the pump.
Figure 56: Level/Timed pump configuration
Set the pump name by touching the Name field for
the pump you are configuring. This is the “Source”.
Each pump can be configured to run individually or
as part of a pump group. For each pump to run
standalone based on it’s own level control, select
each pump to be in a separate group. To use the
run-time of the pumps to “Lead Select” a group of
well pumps, put them in the same group. When the
first pumps level (or level/time combination) calls for
the pump to run, all pumps in the group will be
evaluated to determine which will run, based on run
hours and switch settings.
Timed pump can be configured with or without level
control. A timed pump will be enabled to run on the
days specified, after the start time and for the
duration specified. If also level controlled, then the
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
