Hitachi HISCREW V PLUS NEXT Series - Power Interruption and Restart; Instantaneous Power Interruption Restart Function

5.1.4 Instantaneous Power Interruption
Restart
This compressor is equipped with a function of
Instantaneous Power Interruption Restart. If the
Instantaneous Power Interruption occurs, this function
detects it, Make AUTO START light blinks and waits
until the pressure drops clown to 0 MPa, then the unit
automatically restarts.
Also, if an abnormality occurs in the controller (the
main motor), the compressor stop once, as seen in the
Instantaneous Power Interruption Restart, and then will
be restarted by the retry function. (The history is
recorded to E6.XX.)
(E0.44 is displayed on the digital monitor.)
① If the duration of the instantaneous power interrup-
tion does not exceed 10 seconds, the above function
works.
② The compressor automatically stops running and
the START light goes off.
③
When the power supply is interrupted,
AUTO
START
light on the operation panel blinks.
④ The compressor will automatically restart 45 sec-
onds after POWER recovery.

(1) Instantaneous power interruption means the instanta-
neous drop of voltage to 0 V.
(2) When such time is longer than 10 seconds, the sensor
detects it as a power failure and stops the unit. In such
case, the unit will not restart automatically.
So, press the START button to start the unit again.
(3) If instantaneous stop occurs for the fan inverter, the fan
inverter automatically instantaneous power interruption
restarts. The compressor continues operating as is at
this time. (History is not displayed.)
