Thorlabs offers a compact, two-way power supply unit (TPS002), allowing up to two K-Cubes to be
powered from a single outlet. However, if an external supply is to be used, see Section 5.1.1 for power
supply connector pin out details.
Caution
If an external power supply is used, ensure that the 3 voltage supplies are turned on and off
simultaneously. Applying the voltage supplies with a large (more than 1 second) time delay between
them can result in the K-Cube showing an incorrect reading.
3.3.5. Powering Down The Unit
Warning
Always use the front panel ON switch to power down the unit. When in the ON position, the unit is fully
powered up. When the switch is turned to the Standby position, the unit initiates a controlled power
down sequence, saving all user adjustable parameters to non-volatile memory before turning off the
power. For the first few seconds, the shutdown can be cancelled by turning the switch on again, in which
case the unit will save the parameters but will remain powered up. In a powered down (Standby) state,
the logic circuits are powered off and the unit will draw only a small quiescent current.
3.4. Connect The Hardware
1)
Perform the mechanical installation as detailed in Section 3.2.
2)
Install the software.
Caution
During items (3) to (6) the instructions should be followed strictly in the order stated. Problems
may occur if the process is not performed in the correct sequence.
3)
Connect the Controller unit to your PC.
( Note . The USB cable should be no more than 3 meters in length. Communication lengths in excess of
3 metres can be achieved by using a powered USB hub).
Caution
During item (4) ensure the power supply unit is isolated from the mains before connecting to
the K-Cube unit. Always power up the K-Cube unit by connecting its power supply to the mains.
DO NOT connect the K-
Cube unit to a 'live' external power supply. Doing so (i.e. “hot plugging”)
carries the risk of PERMANENT damage to the unit. Similarly, to power down the unit,
disconnect the power suply from the mains before disconnecting the K-Cube unit.
4)
Connect the Liquid Crystal Retarders to the Controller unit - see Section 3.3.1..
5)
Connect the Controller unit to the power supply - see Section 3.3.2..
6)
Connect the PSU to the main supply.
7)
Switch ‘ON’ the unit using the switch on the front panel.
The unit takes about 5 seconds from power application until warm up is finished, during which time the
software revision is displayed. Windows
TM
should detect the new hardware. Wait while Windows
TM
installs
the drivers for the new hardware.
8)
The unit starts up with the output disabled. This must be enabled before any other settings can be
adjusted - see Section 4.1.2..
9)
LCD screen displays the start menu as shown below:
