Input alarm reset signal (RES) for at least 6 msec.
Then, the *ALM signal returns to ON, so after confirming that it is turned ON, turn the RES signal OFF.
Note: Whatever the alarm, always investigate the cause of the alarm and remove the cause before
resetting the alarm. If the cause of the alarm cannot be removed, or when the alarm cannot be reset
even after the cause has been removed, please contact IAI.
If the same error occurs again after a reset, the cause of the alarm still exists.
