Lead On Level
• Pump Up mode – In tank filling operations, the TCU starts the Lead, or first,
pump when the tank’s level falls below this set point.
• Pump Down mode – In well emptying operations, the TCU starts the Lead, or
first, pump when the well’s level rises above this set point.
Lead Off Level
• Pump Up mode – For tank filling operations, this is the tank’s maximum
operational level. The TCU turns off the Lead, or first, pump when the tank’s
level rises above this set point.
• Pump Down mode – For well emptying operations, this is the well’s minimum
operational, or Off, level. The TCU turns off the Lead, or first, pump when the
well’s level falls below this set point.
Flow Equalization
The Flow Eq Lead option is a function utilized by the DFS patented “Symphony -
Harmonious Pump & Flow Management” technology. For more information about
Symphony please contact the DFS Sales Department at 321-259-5009 or by email
at sales@dataflowsys.com.
Low Level
• Pump Up mode – In tank filling operations, all pumps are running and alarms
are activated when the tank’s level falls below this set point. This level must
be set below all other levels.
• Pump Down mode – In well emptying operations, pumps are shut down and
alarms are activated when the well’s level falls below this set point. This level
must be set below all other levels.
XDCR 1 Low Cal Point
The value expected when the input is at its lowest signal level (4 mA or 0 V,
depending on transducer type).
XDCR 1 High Cal Point
The value expected when the input is at its highest signal level (20 mA or 5 V,
depending on transducer type).
XDCR 2 Low Cal Point
The value expected when the input is at its lowest signal level (4 mA or 0 V,
depending on transducer type).
XDCR 2 High Cal Point
The value expected when the input is at its highest signal level (20 mA or 5 V,
depending on transducer type).
XDCR Fault Mode
• Disable – Set Transducer Fault Mode to Disable if the station will not be using
one of the other fault mode options (Analog2 or Floats). If this option is set to
Disable and high and/or low floats have not been enabled, the system will shut
down when a transducer fault occurs in either pump up or pump down station
operation.
• Analog2 – When an auxiliary transducer is connected and this option is
selected, a fault with the primary transducer will cause the TCU to switch to
the backup transducer.
• Floats – When this option is selected, a fault with the primary transducer will
cause the TCU to switch to normal float behavior. This mode requires an Off
float to shut off the pumps and a miniumum of one float (Lead to High) to start
the pumps.
