suppress the alarm condition for the specified channel. Application of the control voltage to the
appropriate terminal block connections will inhibit the alarming of the associated channel locally as well
as remotely. Disabling a channel does not prevent the monitoring of the intensity level for that channel
on the 2 digit panel display. The 0 to 10 volt or the 4 to 20 milliamp outputs are not affected by the
remote channel disable inputs.
A channel may be permanently disabled by hard wiring that channel's disable input to 24 volts (AC or
DC). This is useful in OEM applications when less than four lamps are to be monitored. The Remote
Disable input overrides the front panel switch for that given channel. If a channel is disabled from the
Remote Channel Disable input, it cannot be enabled from the front panel. Table 4 defines the terminals
to which 24 volts must be applied to disable the designated associated channel.

Display

3.1
Three digit liquid crystal display (LCD), 0.5" high digits.
Display channel selection by turning a rotary switch to the desired channel. Display range of 0 to 199% can
be displayed.

Operating Temperature

3.2
Operating temperature is 0 to 50 degrees Celsius.

Sensor Input Current Range

3.3
MultiBrite was designed for use with EIT UVISENSORS.
Current range through the sensor input terminals is 0.2 to 2.0 microamperes for a "100%" full scale reading.
Display reading is adjustable by turning a respective channel's screw slotted "CALIBRATE" control located
on the front panel.

Signal Output Specifications

3.4
Three different signal output configurations for each channel.
Position 1: 0 to 100% output represented by 0 to 10 volts DC and 4 to 20 mA DC.
