Control and supervision
The control functions through the relays can be executed using a serial link. These
functions particularly constitute the changes of an individual relay setting parameters,
the changes of the setting group, the remote control of the circuit breaker, as well as
the functions and the locking of the selected output relays.
The remote control is limited to the selected control functions in the table of the relay
menu. In order to modify this selection, a corresponding password is needed. The
CRC and the controls of the message length are used every time a message is
received . No response is given for message received with an error detection. The
principle unit can be re-initialized in order to send again an order, as often as it
seems necessary, if it does not receive any response or have received a response with
an error detection.
