Operation with Maxa Beam Optical Filters
The Maxa Beam optional filters utilize a quick disconnect snap lock feature for ease and speed of
installation or removal. There is a small blue indicator located on the top of the light housing just behind the
front lens ring. This indicator is to alert the operator that the light is on when being operated with one of the
filters installed.
To attach filters
1)
Line up tabs on filter with slot on searchlight lens attachment ring.
2)
Place filter over front of the searchlight.
3)
Turn filter counter clockwise until it is seated and it locks in place.
Remote Operation
The searchlight models MBS-450 and the MBS-430 have an 8-pin connector installed on the left rear
corner of the light next to the power connector. See figure 5 for pin out identification.
The remote control capable searchlights allow the operator to hard wire the searchlight to a MBA-8425
remote control handle or to a auxiliary control panel. This allows remote programming and operation of all
standard functions. Remote power and control cables are available in 25’ and 50’ lengths.
All contact closures (switches) used for remote operation must be momentary, normally open. During
operation, the microprocessor is constantly scanning the status of all input lines from the remote control
input connector. When the closure of one of the remote switches is detected, the microprocessor executes
the appropriate command. Input lines 3,4,5,6 and 7 are active high. These lines have internal pull down
resistors.
Line 1 (pin 1) is an output line which provides power for the on/off and other remote functions. Caution:
There is power applied to line 1 (pin 1) at any time there is power supplied to the light, even when the light
is off. This line is tied directly to the power input connector. When wiring the on/off switch and remote
control switches, line 1 (pin 1) must be tied to one side of all switches in parallel. Line 2 (pin 2) is chassis
ground and should be wired to the cable shield for long cable runs. Line 3 (pin 3) from the on/off switch is
also scanned during the operation. When the on/off switch is closed again after the light has been turned
on, the microprocessor disables all normal operational modes and is then in the programming mode. If one
of the other remote switches is closed, while the on/off switch is closed one of the user functions will be
reprogrammed.
Maintenance
The only maintenance required on the Maxa Beam Searchlight is to periodically clean the body with a
damp cloth and to keep the front lens cover clean. Clean the front lens with window cleaner.
Lamp Focus
If the searchlight is dropped or receives any heavy impact from transportation or shipping, it may be
necessary to refocus the lamp to insure proper operation and maximum output. Refocusing of the lamp
requires centering the lamp within the reflector.
1)
Using a 1/16” allen driver remove the 2 focus access screws, one on the right front side of the main
body and one just left of the front of the handle (see fig. 4).
2)
Shine the light beam onto a flat surface about 50 feet away.
3)
Insert the allen driver into one of the focus access holes. A slight rotation and/or side to side movement
may be required until the allen drive is properly seated into the adjustment screw.
4)
After the allen driver has been inserted into the adjustment screw, turn the allen driver to center the
