1 INTRODUCTION Thank you for selecting the Martin CX-4. The CX-4 is an automated profile spotlight designed for a 150 watt discharge source. It provides colors, gobos, 5 beam angles, a frost effect, continuous dimming, adjustable focus, and multiple control options. CX-4 SAFETY INFORMATION Warning! This product is for professional use only. It is not for household use. This product presents risks of lethal or severe injury due to fire and heat, electric shock, and falls.
To protect yourself and others from burns and fi re • Never attempt to bypass the thermostatic switch or fuses. Always replace defective fuses with ones of the specified type and rating. • Keep all combustible materials (for example fabric, wood, paper) at least 0.1 meters (4 inches) away from the fixture. Keep flammable materials well away from the fixture. • Replace the lamp if it becomes defective or worn out.
2 LAMP The CX-4 uses the Philips CDM-SA/T (short-arc, tubular) 150W discharge lamp. If desired, the GE Arcstream 150 may be substituted. Lamp Efficiency Color Temp. Average Life Philips CDM-SA/T 150W 85 Lm/W 4000 K 6000 h GE Arcstream 150 77 Lm/W 4000 K 6000 h The CX-4 can be modified with a different lamp socket that allows use of the following lamps: • Martin HTI 150 W, 2000 h • OSRAM HTI 150 W, 750 h • GE CSS 150 W, 1000 h Please contact your Martin dealer for details.
5 Insert the lamp assembly with the black metal shield up, between the lamp and the fan. Replace the screws. To ali gn the l amp Realignment when changing the lamp may improve performance. 1 Strike the lamp and project the light on a flat surface. 2 Using a 3 mm Allen wrench, center the hot-spot horizontally with the top-left adjustment screw. Center the hot-spot vertically with the bottom-right adjustment screw.
3 AC POWER CONNECTION The CX-4 power supply must be wired to the voltage and frequency setting that most closely matches the local AC supply. The factory setting is shown on the serial number label. Warning! For protection from fire and electric shock, the fixture must be grounded (earthed). The power supply shall have overload and ground-fault protection. Warning! Verify that the feed cables are undamaged and rated for the current requirements of all connected devices before use.
To rewi re the power suppl y 1 Disconnect the fixture from AC power. Remove the top cover bolts with a 4 mm Allen wrench and lift off the cover. 2 On the transformer, which is located behind the color wheel, move the brown and white wires to the transformer taps shown below for your mains voltage. Do not move the blue wire from terminal 9 or the black wire from terminal 15.
3 The frequency setting (50 or 60 Hz) is selected by moving the black wire on the ballast, which is located behind the effect wheel. To set for 50 Hz, move the black wire to the “230-50” terminal. To set for 60 Hz, move the black wire to the “230-60” terminal. See below. The wire is released and locked by inserting a small screwdriver in the square hole next to the terminal and prying back the spring. 4 Tug lightly on the black wire to make sure that it is connected securely. 5 Replace the top cover.
4 INSTALLATION The CX-4 can be fastened directly to a suitable surface or hung with a rigging clamp bolted to its adjustable mounting bracket. Do not lay the fixture flat on its mounting bracket arms or position it so that there is less than 10 cm (4 in.) clearance around the fan and air vents. For maximum lamp life, do not place the fixture directly on or beside a speaker cabinet. To rig the CX-4 Warning! Always use a secure means of secondary attachment.
5 DATA CONNECTION A reliable data connection begins with the right cable. For best results, use cable specifically designed for RS-485 applications, available from your Martin dealer. CONNECTIONS The data sockets are wired with pin 1 to ground, pin 2 to signal - (cold), and pin 3 to signal + (hot) for compatibility with DMX devices. One or more adaptor cables as shown below may be required for connection to the controller or other lights.
STAND-ALONE OPERATION 6 The CX-4 may be operated in a random-action stand-alone mode without a controller. It may be operated as a single unit or in synchronization with other CX-4s in “master/slave” configuration. Several options are available to modify operation. These are selected with the DIP-switch and are described on page 14. Important! The CX-4 transmits a signal on the data link when DIP-switch pins 2 and 10 are set to ON.
To set the master Important! Set only 1 fixture as master (DIP-switch pin 2 and 10 ON). ON 2 Set DIP-switch pins 3, 5, 6, 7, 8, 9, and 11 to OFF. 1 2 3 4 5 6 7 8 9 10 11 12 ON 1 Set DIP-switch pins 2 and 10 to ON. 1 2 3 4 5 6 7 8 9 10 11 12 3 Select trigger and speed options with DIP-switch pins 1 and 4. To set a sl ave 1 Set DIP-switch 10 to ON. 2 Set pins 1, 2, 3, 4, 5 and 11 to OFF. 3 Select options with DIP-switch pins 6, 7, 8, and 9.
7 MC-1 OPERATION The CX-4 is fully compatible with the Martin MC-1 Controller. See the MC-1 user manual for additional information. MC-1 MODE SETTINGS DIP-switch pin 10 must be set to OFF to enable MC-1 mode operation. Changes to the setting take effect after the fixture has been turned off and on. DIP-switch pins 6, 7, 8, and 9 select control options. The remaining pins have no effect in MC-1 mode.
8 DMX OPERATION DMX MODES The CX-4 has 2 DMX modes to choose from: a 1-channel mode that provides control of the built-in stand-alone features, and a 6-channel mode that provides full control of all effects. The 6-channel mode provides 2 options for controlling the effect wheel that are selected with DIP-switch 12. To select DMX mode 1 Disconnect the fixture from power. Set DIP-switch pin 10 to OFF. 2 To select 1-channel DMX mode, set DIP-switch pin 11 to ON.
Find the address in the table. Read the settings for pins 1 - 5 to the left and read the settings for pins 6 - 9 above the address. “0” means OFF and “1” means ON. Pin 10 is always OFF for DMX operation.
1-CHANNEL DMX OPERATION The functions shown in the following table are available in 1-channel mode. When a “stand-alone” function is selected, the fixture steps through a routine using a built-in microphone to trigger the action to the beat of the music. Note that multiple fixtures cannot be synchronized in this mode.
BASIC 9 SERVICE The CX-4 requires simple routine maintenance. The maintenance schedule depends heavily on the operating environment; please consult a Martin service technician for recommendations. Any service procedure not described here should be referred to a qualified technician. Important! Excessive dust, grease, and smoke fluid buildup degrades performance and causes overheating and damage to the fixture that is not covered by the warranty.
To clean the fan and air vents To maintain adequate cooling, dust must be cleaned from the fan and air vents periodically. 1 Remove the data and power cables and stand the fixture on end. 2 Remove dust and dirt from the fan blades and vent grills using a soft brush, cotton swab, vacuum, or compressed air. REPLACING FUSES The CX-4 has 2 fuses. The main fuse holder is built in to the mains input socket. The secondary fuse is located on the printed circuit board.
10 TROUBLESHOOTING Problem Probable cause(s) No power to fixture. One or more of the fixtures is completely dead. Remedy Check that power is switched on and cables are plugged in. Primary fuse blown. Replace fuse. Secondary fuse blown. Replace fuse. The controller is not connected. Connect controller. XLR pin-out of the controller does not match pin-out of the first fixture on the link (i.e. signal is reversed).
