4 TCM-39032
CHAPTER 1
Installation
This section describes the procedures for installing and removing a TCM-39032
module from the LDC-3900.
Note: The LDC-3900 will power up in a default state upon detecting any change in the
LDC-3900 system configuration (such as installing a new module). All parameters (except
SAVE / RECALL settings) will be set to default values, based on the new configuration.
Calibration data is stored in the TCM-39032 module itself, and is never lost due to
reconfiguration of the LDC-3900.
To install the TCM-39032 module into the LDC-3900, follow these steps:
1 Turn the LDC-3900 power OFF.
2 Place the TCM-39032 module into an open bay on the back of the LDC-3900 and slide
the module into place. There are tracks at the top and bottom of the bay which guide the
module into place. Push the module into place until the board edge clicks into place with
an audible “pop”. This indicates that the module is “locked” into place. Screw the Module
Locking Screws into the back panel to secure the module. It is then ready to be used in
the LDC-3900.
3 Power up the LDC-3900
4 After the LDC-3900 has completed its power up sequence, the ( ADJUST ) LAS indicator
which corresponds to the newly installed TCM-39032 module should be lit in green,
indicating that the module has been recognized as a LASER current source in its
respective bay.
To remove the TCM-39032 module from the LDC-3900, follow these steps:
1 Turn the LDC-3900 power OFF.
2 Unscrew the Module Locking Screws which secure the module to the LDC-3900 back
panel.
3 Grasp the TCM-39032 module by the handle which extends from the bottom of the back
panel. Gently, but firmly, pull the module out of the LDC-3900.
4 If the TCM-39032 module is replaced in the LDC-3900 before the LDC-3900 is powered
up again, the LDC-3900 will retain its memory of all parameter settings and SAVE /
RECALL values. However, if the LDC-3900 is powered up and detects a change in its
system configuration, all parameters and SAVE / RECALL information will be lost.
Calibration data is stored in the TCM-39032 module itself, and is never lost due to
reconfiguration of the LDC-3900.
