To 10 Volt Output Connections; Back Panel Analog Connector Definitions; Output Selection Table - EIT MULTIBRITE MB100AC1 Operator's Manual

Caution must be exercised in connecting the signal loads to the system because the four connectors on the
back panel are identically the same. For convenience, the signal wiring may be attached to the connector
terminal strip before the connector is inserted into the mating back panel connector. Figure 10 illustrates the
connector layout.

2.7.1 0 to 10 Volt Output Connections

A continuous analog voltage output is available for each of the 4 lamp monitor channels in the
MultiBrite System. The 0 to 10 volt output signal is capable of driving a resistive load greater than 10K
Ohms. Connections to the output should be made using a twisted pair shielded cable with the shield
terminated at the MultiBrite output terminal block. The 0 to 10 volt output is a continuous voltage
analog representation of the relative intensity of the lamp being monitored. The voltage signal is directly
proportional to the percentage reading on the front panel display. Zero to 10 volts corresponds to zero to
100%.
Switches for each of the 4 channels inside the MultiBrite enclosure allow the user to select 3 different
continuous analog output options. The option described above, 0 to 10 volts out for 100%, is selected
inside the system before it is shipped from the factory. To change the option on the switches, the top
cover of the MultiBrite must be removed and the proper switch setting must be selected. The options
and their associated switch settings are summarized in Tables 2.4-1 and 2.4.1-1. To gain access to the
switches, remove the two screws on the top of the instrument near the front panel. Locate and remove
the 4 screws on the back panel of the instrument. With the 6 screws removed, the top cover-back cover
may be removed exposing the 4 switches. The desired option may be selected by using a screwdriver to
select the associated switch position.
