13 Configuration Parameters

The Configuration Parameters are accessible from the software configurator or through the serial
communication port RS485.

Example:
CD3200-1PH from 15A to 110A
Byte Lo = Load Voltage
This parameter show the Voltage rms value
0 ÷ 255 (0 ÷ FF Hex)
Value depends on the Unit type
Byte Hi = Load Current
This parameter shows the Current rms value.
0 ÷ 255 (0 ÷ FF Hex)
Value depends on when turns have current transformer and from his size's.
With one passage on the current transformer (CT) 25/0.05A, the max value
corresponds to the max value of the CT:
Read value=255 (FF Hex) -> Load Current= 25A
Byte Lo = Set-point Voltage
This parameter is the Set-point voltage saved by the Calibration Procedure
0 ÷ 255 (0 ÷ FF Hex)
Byte Hi = Set-point Current
This parameter is the Set-point of current below which HB alarm occurs
0 ÷ 255 (0 ÷ FF Hex)
This value is the load current(P001H) minus % value of parameter P126H
Status Table
It's a tab in bit that represent the "Status" of thyristor unit
Bit 0 = 1 -> Short circuit on SCR
Bit 1 = 1 -> Load Failure (HB Alarm)
Bit 2 = 1 -> Output signal ON
Bit 3 = 1 -> HB Calibration in progress
Bit 4 = 1 -> Current Limit Flag
Bit 5 = 1 -> Thermal switch
Command Table
It's a tab in bit for remote commands via RS485
Bit 0 = 1 -> Activate HB Calibration procedure
Bit 1 = 1 -> Input Command from RS485 (see P005)
Bit 2 = 1 -> Disable Output signal (Only with Input from RS485)
Bit 3 = 1 -> Reset HB Alarm
Bit 4 = 1 -> Current Limit via RS485 (see P007)
When unit is switch off all command parameter are set to 0
Input command signal
This parameter reads the Input command signal (see par. 7.4)
When the P004 Bit1 =1 This parameter could be written and become the Input
Command from RS485
0 ÷ 255 (0 ÷ FF Hex)
Input 4mA -> P005L = 0
Input 12mA -> P005L = 128 (50%)
Input 20mA -> P005L = 255 (100%)
Byte Hi = Ramped Input command signal
This parameter reads the Input command signal after the ramp
0 ÷ 255 (0 ÷ FF Hex)
Input 4mA -> P005H = 0
Input 12mA -> P005H = 128 (50%)
Input 20mA -> P005H = 255 (100%)
