Calibration
NOTE:
• During calibration, the display will alternate "CAL" and the kilowatts reading of the attached
pump motor.
• The SPGC-220 calibrates only when the STP has no abnormalities and a dispenser handle is
turned on within 10 minutes of calibration starting.
• If you have a blending dispenser system, you can select the mid-grade handle at the
dispenser to calibrate all blended product SPGC-220s simultaneously.
• If the controller loses power, it retains the calibration data.
• DEF Submersibles follow the same installation procedure as normal SPGC-220s but must
must be set to DEF mode (SW2 Pole 6 set to ON) before calibration.
IMPORTANT:
• You must calibrate all SPGC-220s before you operate them.
• Make sure there is no flow during calibration, otherwise the controller will incorrectly
detect abnormal conditions.
• If you use electronic line leak detection, make sure the SPGC-220 is in calibration mode
before you turn on the dispenser handle. If the controller is not in calibration mode, the line
leak detector senses a fault and does not provide a dispenser hook signal to the SPGC-220.
This prevents the SPGC-220 from calibrating until you reset the line leak detector.
• Make sure the product level in the tank is above the motor intake before you start
calibration.
• Prior to calibration, make sure SW2 Pole 6 is switched to ON for DEF MODE, if applicable.
(The factory default is SW2 Pole 6 OFF for petroleum pump motor assemblies.)
Calibration steps
1. Close either the STP clamp valve or a ball valve at the STP discharge, attach the cover of the
controller to the base, and then turn on the power supply to the SPGC-220. The display will
flash "UnC" while the audible alarm beeps to indicate that the SPGC-220 is not calibrated.
2. Press and hold the Silence/Calibrate button (for approximately 10 seconds) until the display
alternates between "CAL" and the kilowatts reading of the attached pump motor (which
should be 0.00 kilowatts until the PMA is running).
3. Release the Silence/Calibrate button to begin the calibration.
NOTE:
When you are working with Primary-Secondary and AC configurations, put the Primary
and all Secondaries into Calibration mode before you proceed to the following step.
4. Lift a handle on a dispenser to turn the pump on. After approximately 16 seconds, the
controller records the voltage, current, and power snapshot. When the snapshot is
successfully recorded, the display alternates between "run" and the percent calibration
reading (which should be close to 100 +/- 5 at deadhead with no flow). This indicates the
calibration is complete. Turn off the dispenser handle, and open the STP clamp valve or ball
valve. If the controller does not calibrate, the controller beeps and the displays flashes red
with a fault code that indicates the abnormal condition encountered during calibration. See
the “Troubleshooting” chapter to identify and correct this condition.
