Low Float
Enabled or
Disabled
Enable this setting to use a lowlevel float to
override normal pump control if a transducer
fault occurs.
page 54
High Float
Enabled or
Disabled
Enable this setting to use a highlevel float to
override normal pump control if a transducer
fault occurs.

Fault Mode
Analog2
Select Analog2 to have the TCU switch to the
second analog input for pump control when a
transducer fault occurs.

Transducer High
Float Fault
Enabled
Enable to generate a transducer fault when a
high float condition occurs.
page 54
Transducer Low
Level Fault
Enabled
Enable to generate a transducer fault when a
low float condition occurs.

Bubbler Noise
Fault
Enabled or
Disabled
Enable only if the system is a bubbler system
and you want to generate a transducer fault
when the TCU doesn’t detect air-pump
induced noise.
page 52
High Float
Override
Enabled or
Disabled
Enable this setting to give the High float
precedence in the event of an Off float failure
when the TCU is in Floats fault mode.

Minimum Run
1.0
Minimum time pumps should run. Used to
prevent short cycling.
page 52
Minimum Off
0.5
Minimum time pumps should remain off.
Used to prevent short cycling.

Alarms
Pump Operation
Behavior
Transducer Low
Condition
Normal pump
operation
Low well alarm and transducer fault alarms are
generated. Control switched to second transducer.
When the transducer level returns to normal range,
the Low well alarm clears and normal pump operation
resumes. Transducer fault alarm remains active and
control remains on second transducer until the TCU
has been reset.
Transducer High
Condition
All pumps on
A high well alarm is generated, and all pumps are
staggered on. When the transducer level returns to
normal range, the High well alarm clears and normal
pump operation resumes.
Transducer noise
fault
Transducer fault
Normal pump
operation
A transducer fault is generated, and the TCU switches
pump control to the second analog input. Pumps
operate normally under this condition. The transducer
fault alarm remains active until the TCU has been
reset.
