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)
