Beam adjustment
Correct adjustment of the beam of the Inground 200 is critical for correct illumination of the target.
Adjustment is best carried out after dark.
Warning!
Danger of burns, electric shock and lamp explosion!
• Beam adjustment must be carried out by authorized electrical personnel and in
clean, dry conditions only.
• Heat-resistant safety gloves and safety glasses must be worn.
• Do not look directly into the lamp.
• Make sure that nothing falls into the fixture while the front glass and lens are
removed.
You will need 4mm and 2.5mm Allen keys for this task.
To adjust the beam:
1. Depending on whether the Inground 200 has been in operation or not, ensure that the fixture is at
optimum temperature for adjustment by following one of these two alternatives:
a)
If the fixture has been in operation
before you want to adjust the beam, do not switch it off.
Instead, remove the front glass and lens (see
“Front glass and lens: removal and refitting”
page 17) and wait 15 minutes for the lamp module to cool slightly.
b)
If the fixture has not been in operation
before you want to adjust the beam, remove the front
“Front glass and lens: removal and refitting”
on page 17), apply power and
wait 15 minutes for the lamp to warm up to operating temperature.
2. Loosen the two 2.5mm beam adjustment ring Allen screws (A) and rotate the lamp module until it
can be tilted towards the target.
3. Make sure the beam adjustment ring screws (A) are pushed out towards the edges of the module
to engage the retaining clips, and retighten the screws to clamp the beam adjustment ring in
place.
