PSL 5.0 Pump Station Level Controller
CALIBRATION
Calibrate the PZ Sensor for Level Measurement
1. Before starting the calibration determine:
a)
MAX RANGE = ________________
(Maximum range = distance from Sensor to Zero level)
b)
MAX LEVEL = ________________
(Maximum level of product being measured)
c)
MIN RANGE
= ________________
(Distance from sensor to Max Level)
Minimum range = MAX RANGE - MAX LEVEL
(must be at least 8" / 203 mm depending on sensor model)
2. Check the maximum range with the sensor installed by:
a)
When liquid is at zero level press
to view the Range reading in the
Status menu. Use this range measured by the PSL 5.0 as the Max Range
setting.
or
b)
Carefully measure distance from sensor to zero level with a tape measure,
and use this measurement as the Max Range setting.
Redundant 4-20mA input (pressure) Sensor Installation and Self-
Calibration
1. Install the redundant 4-20mA input sensor near the bottom of the well
according to manufacturer’s instructions and below the zero level.
2.
Ensure that the PSL 5.0 with PZ sensor has been properly calibrated to
measure water level and is functioning properly.
3.
Connect the 4-20mA redundant sensor to the PSL 5.0 SRC terminals when
the transmitter is loop-powered (24VDC power provided by the PSL 5.0) or
to SNC terminals when the 4-20mA transmitter is powered from another
source.
4.
Operate the PSL 5.0 through several pump cycles to allow the 4-20mA input
sensor to self-calibrate.
5. Note: When 4-20mA input sensor has completed self-calibration the Message
window will indicate that Sensor B status is Good.
