6 Configuration of the receiver
The receiver configuration phase allows to optimise its functioning according to the particular
requirements of the plant. The unit must be configured exclusively during the installation phase and by an
installer.
We recommend proceeding with the configuration of the parameters in a systematic way in order to avoid
installation troubles.
The parameters to set during the configuration phase are the following:
• Identification
number of the receiver
• Receiving mode setup
• Type of lenses used
• Protocol and communication speed
• Control voltage of the positioning device and the wiper
• AUX3 / AUX4 auxiliary devices
• Connection with the control unit
• Control voltage of lenses
• Connection of the positioning device and the lenses cables
• Alarms
setting
• Test of the receiver active functions (for PRESET operations)
6.1 Identification number of the receiver
Configure the SW1, SW2 and SW3 rotative-switches according to the address to assign to the receiver as
follows:
SW1:hundred
SW2: ten
SW3: unit
Examples:
Receiver address n.359
Set SW1 to 3, SW2 to 5 and SW3 to 9
Receiver address n.27
Set SW1 to 0, SW2 to 2 and Sw3 to 7
Receiver address n.4
Set SW1 to 0, SW2 to 0 and SW3 to 4

According to the communication type to set follow the following settings:
Current Loop:
JP2 and JP3 to CL position
RS485: see below (setting of RS485 line load)
RS232: No setting needed
6.3 Setting of RS485 line load
