The table below provides an overview of fault states that result in opening of the 63A-64A
outputs. To guarantee high safety standards, these outputs are used for information
purposes only; they do not prevent switching. When requested, the transfer switching
equipment will always attempt to switch.
The transfer switching equipment can be operated manually in every case with the supplied
handle.
States in which the motor
operator is not available
Transfer switching equipment
is in "manual operation"
mode
Motor operator has not been
recognized
Supply voltage of the motor
operator outside the limit
Operating fault (caused by
too many operations per
minute)
Autotest of the inputs on the
motor operator failed (pin 312
to 317)
Operating fault on the "Man-
ual"/"Auto" switch
Switched switch position not
reached
Priority command OFF posi-
tion active (pin 313 - 317)
Unexpected current flow
through the motor when it is
in no-load operation
No power supply of the motor
operator

Remarks
The user has intentionally turned the switch on the motor
operator from the "Auto" position to the "Manu-
al" position. As the transfer switching equipment is not
available for remote control, this state is indicated with
the opening of the relay.
If the switch is turned to the "Auto" position, the state
resets itself.
The internal availability test is performed when switching
on, when changing the switch on the motor operator from
the "Manual" position to the "Auto" position, and every 5
minutes as long as the switch is in the "Auto" position.
The internal availability test checks the status of the
motor.
A supply voltage of the motor operator of less than 166 V
AC or more than 332 V AC sets the transfer switching
equipment in a non-available state.
The transfer switching equipment has been operated
more frequently than 10 times in one minute. The trans-
fer switching equipment is not available for one minute. It
then resets itself.
The inputs are tested periodically (every 5 min.) and
automatically by the software to ensure they are function-
ing correctly.
Motorized transfer identified although the switch on the
motor operator is at the "Manual" position.
Padlocking mode active, but the "Auto" position is de-
tected internally.
The expected switch position of the transfer switching
equipment has not been reached.
The priority command to switch to the "0" position is
activated by closing of the pins 313 and 317. As this
command has the highest priority, the transfer switching
equipment is not available until the pins are connected.
Without power supply, the relay is open and therefore the
"Not available" state is indicated.
