Chapter 4 Setup
4.1. Setting AC Line Voltage and Fuses
The MDT693B and MDT694B piezo controllers are shipped configured for 100 to
240 VAC operation. There is no end-user adjustment of the line voltage. Simply
select the correct AC line cord for their geographic location.
4.2. Changing
Fuses
To change the power fuse, perform the following steps:
1.
Remove the AC line cord if it is connected to the unit.
2. Locate the fuse tray directly below the AC line cord connection on the rear panel
of the unit.
3.
Carefully use a flat blade screwdriver to open the fuse tray.
4. Remove the existing fuse and install the appropriate fuse (600 mA for the
MDT693B, 500 mA for the MDT694B). The replacement fuse must be a 5 mm x
20 mm, 250 VAC Type T Fuse (IEC 60127-2/III, low breaking capacity, slow blow).
5.
Push the fuse tray back into place, making sure that it snaps and seats correctly.
6.
Connect the appropriate line cord into the AC receptacle and plug the unit in.

Setup
1. Carefully unpack the controller and accessories. If any of the items appear
damaged or missing, do not use the controller. Contact your local Thorlabs tech
support for assistance.
2.
Make sure the
POWER
switch located on the front panel is in the
OFF
position.
3. Plug the female end of the provided AC line cord into the AC input receptacle on
the rear of the unit. Plug the male end into a properly grounded AC socket.
4.
Select the appropriate output voltage limit on the rear panel. The user can choose
from 75 V (Gain = 7.5 V/V), 100 V (Gain = 10 V/V), or 150 V (Gain = 15 V/V) limits.
This switch should only be adjusted while the piezo(s) are disconnected or
when the unit is off.
5.
Connect the piezo device to the controller output(s).
Do not connect piezo devices
to the unit while the unit is on.
6. Turn
the
POWER
switch to the
ON
position.
7. Push and turn the
INT
control knob to adjust the piezo output voltage. For more
advanced controls such as the external input, master scan controls, or USB
operation, please see the Table of Contents for the appropriate section of this
manual.
