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 Remarks Relay 63 A - 64 A
open Warning
LED lights
up
Transfer switching equipment
is in "manual operation"
mode
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.
Yes Yes
Motor operator has not been
recognized
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.
Yes Yes
Supply voltage of the motor
operator outside the limit
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.
Yes Yes
Operating fault (caused by
too many operations per
minute)
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.
Yes Yes
Autotest of the inputs on the
motor operator failed (pin 312
to 317)
The inputs are tested periodically (every 5 min.) and
automatically by the software to ensure they are function-
ing correctly.
Yes Yes
Operating fault on the "Man-
ual"/"Auto" switch
Motorized transfer identified although the switch on the
motor operator is at the "Manual" position.
Yes Yes
Padlocking mode active, but the "Auto" position is de-
tected internally.
Yes Yes
Switched switch position not
reached
The expected switch position of the transfer switching
equipment has not been reached.
Yes Yes
Priority command OFF posi-
tion active (pin 313 - 317)
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.
Yes Yes
Unexpected current flow
through the motor when it is
in no-load operation
Yes Yes
No power supply of the motor
operator
Without power supply, the relay is open and therefore the
"Not available" state is indicated.
Yes No
