Power Supply Programming

P300M/P300MQ/P300MT power supplies may be interconnected to form a complete system of up to six lamps. Through use of the System Interconnections Bus control functions, the entire system may be operated by the lamp control switch of one master power supply, or by a switch on an external control panel.

See Figure 10 on page 42 for the location of programming switch S1. To access S1, remove the six screws on the side of the power supply cover. For programming switch S1 settings, see the table illustration in Figure 11 on page 43.

Settings for Six-Position Switch S1

Positions 1, 2, and 3 of S1 (see Figure 10) must be set to determine whether a power supply is a master or a slave.

Position 4 determines whether a unit fault will turn off all power supplies or only the unit where the fault occurs.

Position 5 indicates to the system bus whether a power supply (either the master or a slave) has an RF Detector connected to it. (There must be at least one RF Detector connected to a system.)
