2.9.1 Lamp Power Detection Input

In addition to the AC power source required to power the MultiBrite System, a Lamp Power Detection
Input is required to make the system operational. This input is used to determine when power has been
applied to the lamps in the curing system. Detection of power applied to this control input initiates a
time delay to the alarm circuit to prevent premature alarms prior to the lamps striking. A 24 volt AC or
DC input is required across terminals 1 and 2 on the lower bottom back panel connector, to enable the
alarm monitoring circuitry. The time delay prior to alarm monitoring is user programmable through the
switches on the back panel connector, to enable the alarm monitoring circuitry. The time delay prior to
alarm monitoring is user programmable through the switches on the back panel of the system. Time
delays from 5 seconds to 1275 seconds (21.25 minutes) may be programmed through the switches on
the back panel. The layout of the switches on the back panel is illustrated in Figure 14. The amount of
time delay is determined by adding the number of seconds associated with each switch in the ON (up)
position. For example, if switches 1, 4, 6, and 8 are in the ON (up) position, the alarm will be enabled 5
+ 40 + 160 + 640 = 845 seconds or about 14 minutes after the Lamp Power Detection input detects
power has been applied to the curing system lamps.

The Lamp Power Detection input requires a nominal input signal of 24 volts AC or 24 volts DC to
enable the alarm detection circuitry of the MultiBrite System. This input must be provided even if a zero
time delay is selected with all switches in the OFF (down) position. Either or both input terminals should
be connected or disconnected from the 24 volt (AC or DC) input by controls applying power to the
lamps of the curing system.

2.9.2 Remote Channel Disable Inputs

A remote Channel Disable input is available for each of the four monitor channels. Control inputs for the
respective channels are located on the lower bottom back panel connector as illustrated in Figure 13. The
disable inputs have identical functionality causing a channel alarm to be suppressed when 24 volts AC
or DC is applied to the appropriate terminals. External control circuitry used to place a specific lamp in
"Low Power", standby, or disconnect mode may be used to provide the 24 volt AC or DC input to
