d) Reset
After the failure is removed, a stored error has to be reset by pushing the RESET-button
or rather by switching-off and on again the main circuit voltage (3-ph.)
Stop!
A reset in case of too high DC-bus voltage during the braking operation is not recommended. If
it is done nevertheless, the power semiconductors are exposed to increased stress, which may
lead to accelerated aging.
e) „Phase failure“
The phase-failure-supervision monitors the mains supply in all 3 phases.
In case of a breakdown of one phase the unit stays still in function, but with
reduced feedback power.
The power feedback unit reacts in different ways on phase failures. One possibility is
the "2 phase operation", the other one let the system get out of operation and the collec-
tive-error-relay signals the failure.

Note!
Jumper J7 only exists from version 1.4.2 of the control board. Error storage "ON" means that
the error "phase failure" is shown via LED until you confirm. Error storage "OFF" how-ever
means that the error "phase failure" is shown via LED only as long as the failure really exists.
