PM-23 PUMP MONITOR MANUAL
SET:UNDER LOAD
UL=12,312 W
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-23 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-23 will disconnect the
pump if the power is above the selected value.
SET:OVER LOAD
OL=28,340 W
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. The overload value should
not be less than the underload value. If this happens
an error will be displayed until the overload setting is
increased.
UNDER VOLTAGE
Press the SETUP button and the under voltage setup
will be displayed , if the voltage is under this value the
pump will shut down.
SET: UNDER
VOLTAGE= 200 V
SET:OVER
VOLTAGE= 245 V
Use the arrow buttons to adjust the desired voltage.
Press SETUP again to exit.
Operation
NORMAL CONDITIONS
The Pump LED is ON when the pump start, and the
Failure LED is OFF, the display shows the voltage,
current and power consumption.
FAULTS:
If a failure occurs the
Failure
LED turns ON and the LCD
diplays the fault during trip delay. After the trip delay
the pump will shut down.

RAPID CYCLING
If the pump presents an overload or underload
condition, the power consumption will be displayed
on the screen. This is useful when the system presents
considerable load variation and the automatic
calibration values need to be adjusted.
AUTOMATIC RESET
After a failure has occured (except under /over
voltage), the PM-23 will start to count down the time
set on the restart delay (if the automatic reset is
enabled). The pump will restart when the timer
RESET DELAY
6 MIN. LEFT
OVERVOLTAGE
Finally, press the SETUP button and the over voltage
setup will be displayed , if the voltage is over this value
the pump will shut down.
