If a failure is detected, an alarm trips and stops the converter. Default setting of digital output MDO 1 is
0:Drive OK.
Two conditions may occur:
1) After 0.5 s, the alarm tripped is stored to E
2) The alarm tripped is NOT stored to E
If the alarm tripped is stored to E
reset command to terminal 28 (MDI 1), which is factory-set to 0:Reset.
If the alarm is not stored to E
again and if the ENABLE contact is still closed, the converter is self-reset, but will be able to restart only
after 10s from the instant when power is restored. This is a safety delay set in par. C101 (PwrOn Time)
(factory-setting: 10s).
The safety delay is enabled only for the first start-up after a power failure.
If safe batteries are installed, which activate in case of power failure, the time set in the external timer
must be longer than 10s.
Safe battery voltage can be higher (at least in a first stage) than the magnet rated voltage; also, voltage
set in the potentiometer can be accidentally too low. Make sure that the voltage regulated by the converter
is higher than the battery voltage when batteries are on and the converter is operating again; if not, the
converter will tend to discharge safe batteries. To do so, contact between terminals 29 and 31 (MDO 2)
must be kept closed for the required time period.
