Control panel 15

Service messages

The Service LED on the control panel lights under conditions that require fixture service, and there is a message

describing the service required. To display the message, select

SMSG in the main menu. This item is available only

when the LED is lit. There are two service messages.

Replace lamp is displayed when the lamp counter exceeds 750 hours, which is the rated average life for the

HMI 1200 W/S lamp. The maximum service life is 125% of the average life, or 940 hours.

Fixture overheating is displayed when the head temperature exceeds 120° C (248° F). Overheating is

likely due to dirty air filters, fans, or air vents; incorrect power supply settings, or a defective fan.

Service utilities

Important! Enter must be held for several seconds to access the utilities menu.

TEST SEQUENCES

TSEQ

provides a general test of all effects that can be run without a controller. UTIL/PCBt provides routines

for circuit board testing that are for service use only.

FEEDBACK TOGGLES

An on-the-fly position correction system monitors the color wheels. If a position error is detected, the shutter closes

while the effect resets. This feature can be disabled by turning effects feedback (

UTIL/EFFb) off.

The automatic pan/tilt position correction system may be temporarily turned off under UTIL/FEbA. The off

setting, however, is not saved and the system will be re-enabled the next time the fixture starts. If the system cannot

correct the pan/tilt position within 10 seconds, feedback is automatically disabled.

ADJUSTMENT

The adjustment menu (UTIL/Adj) provides manual control for making mechanical adjustments and is used by

Martin service technicians.

CALIBRATION

The calibration menu (UTIL/CAL) provides utilities to define offsets in software that are relative to the

mechanical reset or home positions. This allows you to fine tune optical alignment and achieve uniform performance

between fixtures. Dimmer and zoom are calibrated to defined points. The other effects are calibrated relative to an

arbitrary reference fixture.

Default offset settings may be restored by selecting default offsets (

UTIL/dFOF).

Calibrating effects

1 Apply power and strike the lamp.

2 To calibrate the zoom, select

UTIL/CAL/ZOOF and press [Enter]. The default value of 128 can be

adjusted up or down to move the diffuser lens relatively forward or back. Make any necessary adjustments

and press [Enter] to save the setting.

3 To calibrate the color wheels to an offset from their mechanically indexed position, select

UTIL/CAL/C1OF and press [Enter]. The default value of 128 can be adjusted up or down to move the

color wheel relatively forward or back from its indexed position. Make any necessary adjustments and press

[Enter] to save the setting. Repeat this procedure if necessary for color wheel 2 (C2OF).

4 Pan calibration is most useful when multiple fixtures are stacked vertically. To calibrate, set zoom, focus, iris,

and tilt position for easy one-over-the-other comparison and set each fixture to the same pan DMX value.

Select one fixture to be the reference fixture. On the other fixtures, select

UTIL/CAL/P OF and press

[Enter]. Adjust the offset as necessary to align the beam with the reference beam. Press [Enter] to save the

setting.

5 Tilt calibration is most useful when multiple fixtures are arranged horizontally. To calibrate, set zoom, focus,

iris, and pan position for easy side-by-side comparison and set each fixture to the same tilt DMX value.
