Page 14: Installation
C H A P T E R PERATION This chapter is a guide to setting up and operating the LDX-3412. The controls and connectors are described, and then step-by-step instructions for connecting and using the LDX-3412 are presented. Installation Before plugging in the LDX-3412 to your AC power source, AC Power Considerations . -
Page 15: Front Panel
Figure 2.1 LDX-3412 Front Panel Power-up Sequence With the LDX-3412 properly connected to an AC power source, pressing the AC POWER off/on switch causes the unit to initiate its power-up sequence. During this period the output terminals are unconditionally shorted and the OUTPUT off/on switch is inhibited for two seconds. -
Page 16: Output Current Adjustment
The OUTPUT off/on switch is located in the lower right-hand corner of the front panel. This switch has a toggling action which turns the output current of the LDX-3412 on and off. When the output is active, the LED indicator just above the switch will be lit. -
Page 17: Rear Panel
OPEN CKT indicator latches on. The OPEN CKT indicator will remain on until the output is manually turned on again. • LIMIT - indicates that the LDX-3412 output is being limited to the setting of the front panel LIMIT knob. When a LIMIT condition occurs, the LIMIT indicator becomes lit. -
Page 18: Output Connectors
Photodiode feedback gain may be adjusted by the user via the COARSE and FINE controls on the rear panel of the LDX-3412. When the CONST P mode is selected, the user may adjust the feedback gain for proper testing of a laser diode. -
Page 19: System Interlock
When disconnecting devices, it is only necessary to turn the OUTPUT off. System Interlock When the LDX-3412 is shipped, an interlock is incorporated at connector J105 (pins 1 and 2). Output current will not flow unless there is an electrical connection made between pins 1 and 2 of J105. - Page 20 +6 volt common mode voltage, relative to the "-" laser current output terminal.

Page 21: Laser Diode Connections And Shielding
Installation Laser Diode Connections and Shielding Before connecting the laser diode to the LDX-3412, be sure that the front panel OUTPUT switch is in the OFF position (LED unlit). Before turning on the OUTPUT, be sure that the current LIMIT has been correctly set. - Page 22 COARSE control back down (CCW) a bit. Then repeat Steps 8 and 9 as necessary. Note: At any time during the operation of the LDX-3412, the output current limit setting may be observed by selecting LIMIT DISPLAY mode. In this mode, the output current will be off and the current limit setting will be displayed on the LED display.
