The parameter value is controlled and refreshed with each command received from a Novar1xxx NRC
PFC, it is not necessary to set it manually. In case of power failure, the last valid value of the
parameter is stored in the unit memory and automatically loaded after the power restoration.
For testing purposes, the parameter value can be set manually too. But, for this it is necessary to
switch the remote control mode off firstly or simply disconnect the communication link temporarily.
3.3.2 Parameter 02 – Remote Controlled PF Serial Number
This parameter is relevant in the RCC-mode only. In other modes it is not displayed.
The remote controlled PF serial number can have value in range 1 ÷ 5. If since last unit powerup or
the unit initialisation at least one PF control request had come ( i.e. a valid pulse signal had appeared
at one of I1 ÷ I5 inputs ), the decimal point of displayed parameter value is dark.
The last valid parameter value is stored into the unit memory and automatically uploaded after the unit
powerup. The fact that the parameter value was reloaded from the unit memory is indicated with
flashing decimal point of displayed parameter value. The same indication is activated after manual
editing of the parameter value.
The decimal point gets dark as soon as the first valid PF control request on I1 ÷ I5 inputs appears.
