The EOL supervision board LBB4443/00(see figure

12.3) contains the following:

X10 Flying leads - Two flying leads (30 cm) with high-temperature insulation to install the EOL supervision board in a loudspeaker (see section 12.3.3).

S700 Address selector - An address selector to set the address of the EOL supervision board (see section 12.4).

S701 Address selector - An address selector to set the address of the EOL supervision board (see section 12.4).

C540 Capacitor - A capacitor for factory adjustments. Do not touch this capacitor.

R441 Resistor - A resistor for factory adjustments. Do not touch this resistor.

12.3.1 Supervision control board

Warning

To prevent the hazard of electric shocks, disconnect the mains cord and the back-up power supplies from the power amplifier before starting installing the supervision control board.

To reduce the risk of electric shock do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. See section 1.2 Intended audience.

Warning

The electronics inside the power amplifier and on the supervision control board are susceptible to electrostatic discharges. Wear an anti-ESD bracelet during the installation of the supervision control board.

Proceed as follows to install the supervision control board in the PRS-xPxxx Power Amplifiers:

1Remove the lid from the power amplifier and locate the output board (see figure 12.4).

2Snap the supervision control board on the ‘table’ bracket (see figure 12.4).

3Fit the supplied flat cable to the connector on the output board and the supervision control board. Do not twist the flat cable and fit the polarization pin of the flat cable in the hole in the PCB next to the connector.

Note

In the spare amplifiers also multiple line supervision boards must be installed for those channels that have multiple line supervision boards in the corresponding main amplifier channels. Otherwise, a Line supervision master mismatch fault event is generated. Single and multiple line supervision boards are not compatible.
