Options under the Main Settings Menu are used to configure the
main functions of the unit, such as the number of pumps, the pump
mode, transducer type, and alternator type.
Main Settings
Number of Pumps
The TCU can be configured to control one, two, or three pumps for simplex, duplex,
or triplex stations, respectively.
Pump Mode
The TCU can operate in two pump arrangements: “pump up” or “pump down.”
Pump up is used to maintain a fill level in a tank system. Pump down is used to keep
a well below a set level.
Transducer Type
The TCU provides four options for configuring a transducer:
• 4-20 mA – analog current-type device.
• 0-5 V – analog voltage-type device (pressure or linear resistive).
• Remote – device located at a remote location; data is sent to the TCU via
telemetry.
• Floats – digital-type device, such as contact closures, float switches, and
pressure switches.
Alternator Type
(None, All, 1&2, 2&3)
Minimum Run Time
To prevent short cycling of the pumps, a minimum run time can be configured.
When used, this option will cause a started pump to run for the specified time before
it can be turned off. The minimum run time can be set between 0 and 2 hours in one-
tenth minute increments. Setting MinmumRun to zero disables the function, which
allows the pump to be turned off at any time after it has been started.
Minimum Off Time
This option causes a pump that has been turned off to remain off for the specified
time before it can be started again. MinmumOff can be set between 0 and 2 hours
in one-tenth minute increments. Setting MinmumOff to zero disables the function,
which allows the pump to be turned on at any time after it has been stopped.
Start Fault Alarm
The amount of time the alarm will sound before the pump starts. The value can be
set between 0 and 99 seconds.
Stop Fault Alarm
The amount of time the alarm will sound before the pump stops. The value can be
set between 0 and 99 seconds.
