Menu Reference
The LO alarm may be set between 0.0% to 100.0%. The default
setting is 20.0%.
3.3.4 A Menu
Accessible by pressing the
key. The “A” menu adjusts the A
setpoint level in the selected units, which defines the upper limit of
the automatic fill function control band. When the measured liquid
level reaches or exceeds the A setpoint, the A LED on the front
panel is energized. When the level falls below the A setpoint, the
LED is extinguished. If the FILL mode is set to AUTO, the A
setpoint functions as the upper limit of a fill cycle.
The A setpoint may be set between 0.0% to 100.0%, but must be
greater than the B setpoint. The default setting is 60.0%.
3.3.5 B Menu
Accessible by pressing the
key. The “B” menu adjusts the B
setpoint level in the selected units, which defines the lower limit of
the automatic fill function control band. When the measured liquid
level falls below the B setpoint, the B LED on the front panel is
energized. When the level reaches or exceeds the B setpoint, the
LED is extinguished. If the FILL mode is set to AUTO, the B
setpoint functions as the lower limit of the fill function, and thereby
initiates a fill cycle.
The B setpoint may be set between 0.0% to 100.0%, but must be
less than the A setpoint. The default setting is 40.0%.
3.3.6 RATE Menu
Accessible by pressing the
key. The RATE menu adjusts
the RATE alarm in the selected units per minute. The RATE alarm
applies to both fill and loss usage estimates. If the
usage estimate
exceeds the RATE alarm limit, then an
alarm symbol appears to
the right of the usage estimate in the default display.
