Page 18: Connecting The Laser Diode
Use a separate shielded cables Photo Diode measurement line. The Laser current lines should be as short as possible and as close together as possible (e.g. twisted) to minimize inductance. Click to go back to Contents Copyright ©2023 Lasertack GmbH... - Page 19 Even if the current requirement is below 2A we suggest to use cables where all the pins are connected. For Anode: 4, 5, 17, 18 For Cathode: 6, 7, 19, 20 Click to go back to Contents Copyright ©2023 Lasertack GmbH...

Page 20: Connecting A Photodiode
We recommend using shielded “twisted pair“ wiring for the monitor diode current measurement. Note The PD needs to be mounted in reverse. The Cathode of the PD needs to be connected to +5V of the pin 8. Click to go back to Contents Copyright ©2023 Lasertack GmbH... -
Page 21: Connecting Interlock
Furthermore, the interlock LED on the LD Driver will change from solid state (interlock closed) to blinking state (interlock open). The LD output cannot be activated when the interlock loop is open. Click to go back to Contents Copyright ©2023 Lasertack GmbH... - Page 22 The maximum TEC output current for the Sirius Series is 5A. Use only the 1mm² ca- bles. It is highly suggested to use shielded cables. Temperature sensor should be used with shielded twisted pair cables. Click to go back to Contents Copyright ©2023 Lasertack GmbH...

Page 27: Power-Up
Connect the driver to a PC using the provided USB-C to USB-A. Once the driver was recognized by Windows, start the Sirius Software. Note LabView Runtime Environment needs to be installed before starting the software. Click to go back to Contents Copyright ©2023 Lasertack GmbH... -
Page 28: Ld Output Configuration
3.3 LD output configuration ATTENTION Check the polarity of the laser diode and the connector. There is no reverse polarity protection for the LD output. A wrong polarity may damage the laser diode. Click to go back to Contents Copyright ©2023 Lasertack GmbH... - Page 29 DO NOT ENTER the maximum operating current according to the LD data sheet in this field. Otherwise the LD can be „overdriven“ and get destroyed. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
- Page 30 Select „Mod. Ext.“ or „Mod. Int.“ for external or internal modulation. Note External modulation provides a DC signal to the analog LD Driver circuit. Shaped signal modulation is not possible in this mode. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
- Page 31 When external modulation is selected, a 0V to 5V needs to be applied to the BNC con- nector. The case of the BNC connector need to be connected to the GND of the modu- lation source. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
- Page 32 In order to be able to use APC, the jumper shown in the graphic needs to be removed. Otherwise, the APC circuit is bypassed. The APC Board can be purchased separately. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
- Page 33 Connect the purple APC Board to the main board of the LD Driver. Note All cables including power supply need to be disconnected from the LD Driver Board be- fore connecting the APC Board. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
- Page 34 Connect an external power supply (adjustable between 0 VDC and 5 VDC) to the Modu- lation Input BNC connector. Set the modulation voltage to 0 V. Enable the laser by clicking the button „Laser On“. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
- Page 35 In case the reading is already negative after Procedure 1, no further setting is re quired. Attention The PD needs to be fully blocked from ambient light. Otherwise accurate setting of the APC Circuit is not possible. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
- Page 36 Internal photo diodes are usually not suitable for long term operation and tend to degrade over time what will lead in instable operation and wrong values. Click to go back to Contents Copyright ©2023 Lasertack GmbH...

Page 37: Ld Modulation Settings
Proper cooling of the Sirius driver board is required in order to prevent overheating of the board and thermal shutdown. For slow speed or CW modulation the pre-voltage should be set ~0.5 V above the LD operating current at nominal output power. Click to go back to Contents Copyright ©2023 Lasertack GmbH... - Page 38 When operating in differential signal mode, the GND from the BNC connector is disconnected from the GND of LD driver circuit. Make sure to use shielded twisted pair signal cables to reduce signal distortion and in- duction noise. Click to go back to Contents Copyright ©2023 Lasertack GmbH...

Page 39: Overcurent Protection Board
If the OCP Board detects overcurrent, it shuts down the LD within a few ns preventing the diode from being damaged or destroyed. The OCP Board can be purchased separately. Click to go back to Contents Copyright ©2023 Lasertack GmbH... - Page 40 In order to reset the overcurrent error, the driver needs to be disconnected from the power suppl and connected again. For safety reasons, as software based reset is not available. Click to go back to Contents Copyright ©2023 Lasertack GmbH...

Page 41: Tec Source Setup
Disconnect all cables from the Sirius Driver board before connecting the TEC Controller Board. Connecting the TEC Controller Board to the Sirius driver while power supply is connected may cause malfunction or damage to both boards and/or the connected TEC element. Click to go back to Contents Copyright ©2023 Lasertack GmbH... - Page 42 Select the right operation voltage for the TEC element. Exceeding its rated operating voltage may damage the TEC element. The TEC Current can only be modified by changing the operating voltage. The operating current is then defined by Ohm´s Law. Click to go back to Contents Copyright ©2023 Lasertack GmbH...

Page 46: Pid Control Loop
P and I settings can be user defined. The D value is controlled by the driver and cannot be changed. P and I values can be entered in field 14 „TEC P Value“ and „TEC I Value“. Click to go back to Contents Copyright ©2023 Lasertack GmbH... - Page 47 When all values are set correctly, the setpoint temperature should be stable with a de- viation of <0.1 °C or better. The theoretical precision of the TEC controller is 0.05 °C. To achieve this value accurate setting procedure is required. Click to go back to Contents Copyright ©2023 Lasertack GmbH...
