Cleaning the UVISENSOR and Mirror

2.4
Whenever the UV lamp or its reflector are cleaned or replaced, the glass window of UVISENSOR should be
cleaned at the same time. Before proceeding, turn OFF all power to the UV equipment and allow it to cool.
Using a Q-tip dipped in denatured alcohol clean the glass window of the UVISENSOR and wipe it dry with
a lint-free cloth. Repeat this procedure on the mirror and/or reflectorized surface of the angle bracket, as
appropriate. The angle bracket will have to be removed from its mounting surface to gain access to its
reflector. Do not touch the mirror or reflector after cleaning.
Note that after relamping or cleaning reflectors, the MultiBrite should be recalibrated

Terminal Blocks

2.5
The MultiBrite is provided with pluggable terminal blocks. This type of connector allows the MultiBrite
terminal blocks to be wired then plugged into the mating connector on the back of the MultiBrite. Strain
relief shells and marking strips are also provided to be installed by the user. The strain relief clamp attaches
to the shell with the provided screws. The shell clamps over the terminal block connector and snaps together.
The marker strip slides into the transparent corner piece. The corner piece then snaps into the shell assembly.
Figure 6 shows the strain relief shell assembled to the terminal block.

Alarm Connections

2.6
Two alarm outputs are available from the MultiBrite system. The Low Intensity Alarm Relay output
available at terminals 15, 16, and 17 of the upper bottom back panel connector indicates the failure of any
one of the lamps being monitored by the MultiBrite system. This alarm output is available as a normally
open (NO) relay contact and a normally closed (NC) relay contact. When the alarm condition exists, the
normally open contact exists, the normally open contact will open and the normally closed contact will close.
While the intensity of the lamps being monitored are above the selected threshold level, the alarm relay will
be energized, closing the normally open contacts and opening the normally closed contacts. These contacts
may be used to control any external alarm device requiring a driving voltage less than 125 volts AC with a
resistive load current less than 0.5 Ampere or 110 volts DC with a resistive load current less than 0.3
ampere. Connections to the Low Intensity Alarm Relay are totally flexible for the users application. The
contact configuration is illustrated in Figure 7.
