High Float (Disabled/Enabled)
If a high level float is being used, High Float must be enabled. If a high level float
is not connected and High Float is enabled, there is no effect on the operation of the
TCU. In a Pump Down Mode (Lift Station) system, all pumps are stagger-started
on a high float condition. In a Pump Up Mode (Storage Tank) system, all pumps are
stopped on a high float condition. A high float condition generates a high well alarm
and an optional transducer fault alarm.
Low Float (Disabled/Enabled)
If a low level float is being used, Low Float must be enabled. Low Float must be
disabled if a low level float is not connected. (If Low Float is not disabled, the
Low Well alarm will interfere with station operation.) In a Pump Down Mode (Lift
Station) system, all pumps are stopped on a low float condition. In a Pump Up
Mode (Storage Tank) system, all pumps are stagger-started on a low float condition.
A low float condition generates a low well alarm and an optional transducer fault
alarm.
XDCR High Float Fault
(Disabled/Enabled)
When this option is enabled, a high float condition generates a transducer fault and
switches control to the configured fault mode. Leaving the option disabled leaves
pump control on the primary transducer whenever a high float condition occurs or
the transducer reaches or exceeds 20 mA.
XDCR Low Level Fault
(enabled/disabled)
When this option is enabled, a low float condition OR a transducer low level
condition (level drops below Low set point) generates a transducer fault and
switches control to the configured fault mode. Leaving the option disabled leaves
pump control on the primary transducer whenever a low float or transducer low
level condition occurs.
High Float Override (Disabled/
Enabled)
When this option is enabled, the High Float is given precedence in the event of an
Off float failure when the TCU is in Float control mode (this can be a floats-only
system or an analog transducer system that uses floats for backup).
Options under the Radio Menu are used to configure the
TCU800’s station address and radio protocol settings.
