LDC-3900 Series 5
CHAPTER 2
OPERATION
This chapter describes how to install, adjust, and operate the LDC-3900 Modular
Laser Diode Controller. It is divided into several sections covering installation,
familiarization and adjustment, warm-up and environmental considerations, and
normal operating procedures.
The section titled LDC-3900 Front Panel on page 9 gives an overview of the
LDC-3900 Modular Laser Diode Controller's front panel features, and it presents a
guide to quickly familiarize the user with the front panel operations.
Installation
General installation procedures and considerations are covered in the following
pages. Module installation and removal procedures are described in the module
manuals.
Note: Modules should be installed or removed from the LDC-3900 only when the power is
off. Whenever the modular configuration of the LDC-3900 is changed, the unit will power-
up using default parameters.
AC Power Considerations
The LDC-3900 Modular Laser Diode Controller can be configured to operate at
nominal line voltages of 100, 120, 220, or 240 VAC. Normally, this is done at the
factory and need not be changed before operating the instrument. However,
check to be sure that the voltage selection (displayed in the center of the power
entry module on the back panel of the instrument) matches the power-line voltage
in your area. Refer to the Line Voltage selection on page 3 if it is necessary to
reconfigure the input voltage range.
