Actuation
In "pump down" operation,
the liquid level must rise above
the NEAR setpoint to de-energize the relays.
Once this condition
is met they are locked in the de-energized state, until the level
drops below the FAR setpoint.
Thus, rising above the near set-
point sets the control state until a low or far level is achieved.
Similarly, for "pump up" operation,
the level must drop below
the far setpoint, which sets the relay state (energized) until the
level exceeds the near setpoint.
Pump Module Calibration
It is usually expedient to calibrate the Level Genie before
installation thereby avoiding the necessity of changing tank levels
to set the trip points.
After installation a spar transducer serves
as an invaluable tool for calibration check.
a. Set mode toggle (SWl) to "CAL".
b. Set maximum range toggle (SW11 to the appropriate 5 feet
or 10 feet maximum range.
