2.
Locate the brown wire labelled ‘V’. If this wire is connected to the 120V terminal then move it to the 100V
terminal. If it is connected to the 230V or the 250V terminal then move it to the 210V or 230V terminal,
respectively.
3.
Switch ON and send a ‘Lamp On’ command to the fixture. If the lamp strikes let it burn at this voltage for
approximately 5 minutes and then switch it off again.
4.
The lamp will now be clear on the inside and ready to re-use at the normal voltage. Disconnect the fixture
from the mains and re-connect the brown wire to the terminal where it was before.
5.
Secure the cover over the voltage terminals before operating the fixture as normal.
If the lamp failed to start, then contact your local Martin dealer for assistance.
Reconfiguring the optical path
The optical system in the PAL can be configured to increase light output or eliminate the hot-spot. The following table lists the
four different configurations that can be achieved. The first (#1) is the factory default configuration.
You may remove or fit the condenser lens and diffusion filter in any combination you wish to obtain the desired performance.
The condenser kit is available from your Martin dealer as P/N 91610004. The diffusion filter is mounted on the CMY module
and the condenser lens on the color/gobo module.
Martin also provides an optional narrow (10.5º to 14º) and wide angle (20º to 36º) lens.
Accessing the electronics section
By removing the top cover from the PAL you will gain access to the printed circuit boards (PCBs). Please follow the instruc-
tion below.
WARNING!
Ensure that the fixture is disconnected from mains power before proceeding.
CAUTION!
The PCBs contain components which are sensitive to electrostatic discharges. To avoid
damaging any components, always ensure that you touch the ground terminal before,
and when, removing the PCBs or any component (CPU / EPROM) from a PCB.
