PM-22 PUMP MONITOR MANUAL
Supply Voltage Selection
When the Pump-Monitor is turned ON for the first time
it will ask the user to input if the supply voltage is
220VAC or 120VAC. This selection is done to calibrate
the voltage readings.
Once the supply voltage is selected it won’t ask the
user again for this setup. If the supply voltage
configuration needs to be changed, power off the PM-
22 by removing the supply voltage. Then keep the
Reset button pressed while you turn ON the PM-22
again. If done correctly the PM-22 will ask for the
supply voltage again.
SELECT:
220 V PRESS RESET
Before the PM-22 unit is ready to be used it MUST BE
CALIBRATED. Calibration may be performed as many
times as desired.
Important Note: Please make sure the PM-22 is
calibrated during normal pumping conditions.
While the pump is operating press and hold both
arrow buttons until LCD displays the calibration.

The PM-22 measures the power and sets the
calibration for underload (UL) at 65% of the power
consumption and at 125% for overload (OL). These are
the recommended values, but they can be manually
adjusted later if desired.
The calibration is permanently stored, it does not
need to be recalibrated if power is lost.
Verify that the pump is running normally (i.e. the
system is pumping water and the motor current is
normal). Try to achieve the maximum water flow rate.
Calibration on a fully recovered well is recommended.
The calibration may be repeated to assure that setup
was done when the pump was running under normal
conditions.

Setup
Press the SETUP button to select between manual or
automatic reset. Press the downwards arrow button to
choose MANUAL reset or the upwards arrow button to
choose AUTOMATIC reset.
RESET DELAY
Press the SETUP button again. If the AUTOMATIC
option is selected the reset delay setup will be shown.
Press the up or down arrow buttons to adjust the
desired reset delay from 1 to 120 minutes.
UNDERLOAD
Proceed by pressing again the SETUP button, the
underload trip value will be displayed. This setup
allows to modify the underload protection if the
a u t o m a t i c c a l i b r a t i o n a d j u s t m e n t w a s n o t
appropriate. The PM-22 will disconnect the pump if
the power is below the selected value.
Use the arrow buttons to set up the desired value in
10W increments. If the button is kept pressed it will
move by 100W increments.
OVERLOAD
When pressing the SETUP button the overload setup is
displayed. This setup allows to modify the overload
protection if the automatic calibration adjustment
was not appropriate. The PM-22 will disconnect the
pump if the power is above the selected value.
SET:OVER LOAD
