  • Page 12: Pi Control

    PI Control C151 has 2 options to control the temperature feedback loop: Internal and External. Internal PI control covers the vast majority of systems and the P and I control potentiometers can be adjusted to obtain the optimal PI. External PI control can be used if the user has a digital PID implementation elsewhere and connected to the Pin 3 of J4.

  • Page 13: External Connections And Cables

    Installation We recommend a first time use of the C151 with a high power load resistor (at least 10W rating) as TEC load and Laser Diode load. These load should connected to the corresponding pins of J1. Such a set-up will enable a system check before connecting to the laser temperature controller system and risking potential damages.
