After checking the LO/RE lamp is OFF, interrupt RUN signal from the control connector.
The pump starts decelerating and the RUN lamp blinks.
The pump stops and the RUN lamp will be OFF.
c) Power OFF
After one minutes or more the RUN lamp turns off, confirm the pump is stopped surely and the CP
placed in the OFF position.
The
display and ALM lamp blink, a few seconds after the CP placed in the OFF position.
After other a few seconds, the display and ALM lamp turns off.
5.3 Operation when momentarily power failure happens
The momentarily power failure means that power supply voltage falls temporarily. The voltage of the
interior DC circuit of the inverter, V
PN
, falls to 190V or less due to the momentarily power failure, the
inverter detects that the DC circuit Under-Voltage (UV). Pump operation continues when the V
PN
returns to 190V or more within one second. Pump operation stops and the ALARM displayed when
the momentarily power failure continues more than one second. Then ALM lamp turns on and data
screen displays “
” or “ ”. In the momentarily power failure condition, pump rotor is driven by
inertia due to interception of power supply. Thus, pumping performance may be decreased than
guaranteed specification.
WARNING
The pump and exhaust piping will remain at a high temperature during operation and for
a short time after the pump has stopped. Be sure to avoid contact and keep inflammable
substances out of reach. Do not remove the outer cover during operation.

NOTE
Be sure to stop by the STOP button or interrupt the RUN signal, and keep the pump
power supply for at least one minute. If the CP places off to stop the pump, the electrical
components of the inverter may be damaged.
NOTE
If the CP turns on under blinking, or ALARM may occur.
Input RESET command to cancel the ALARM before restart the pump.
