Operation
7.2 Functions of the inputs and outputs
124 Manual, 08/2017, L1V30368969104A-02
Functions of the outputs
Outputs 63B and 64B
These outputs provide permanent feedback about the functional capability of the electronic
module and about the product availability of the motor operator
Outputs 63B-64B are closed when the transfer switching equipment is in automatic mode
and ready (not a fault state).
The table below provides an overview of fault states that result in opening of the 63B-64B
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.
States in which the motor
operator is not available
LED fault
indicator
lights up
Fault on the motor operator Refer to the table "States in which the motor operator is not availa-
ble" in chapter Outputs of the motor operator (Page 111)
Fault: internal clock Yes Yes
Motor operator has not been
recognized
Wiring problem (connection between
electronic module and motor operator)
Yes Yes
Fault: Outputs signal for start-
ing / stopping the generator
At least one of the outputs signal for
starting / stopping the generator does not
change its state (pin 72, 74)
Yes Yes
Fault – during autoconfigura-
tion
Detection of voltage, frequency, phase
rotation, position of the neutral conductor
failed.
Yes Yes
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 "Manual" 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" posi-
tion, the state resets itself.
Yes No
Position of neutral conductor
incorrect
The position of the neutral conductor is
different between source I and source II
Yes Yes
Phase rotation faulty The phase rotation is different between
source I and source II
Yes Yes
Supply voltage outside the
limit
Yes No
