    Integrating Some TAC/Invensys Actuators

    I have a few AHU's with MP-5413 actuators on the HW and CHW. Doing some research and they are stated at 2-15vdc. I only have 0-10vdc. So I was looking into some dc to dc transmitters. Then I came across some info, that the actuators only stroke from 6-9vdc.

    What's the deal?

    Thanks for the info.

    So do I understand this right......the range is 3vdc. The starting point(approximate) is 6vdc.....but is fixed. But also states, that the starting point is adjustable. And requires 2-15vdc.

    Now I'm even more confused.

    I threw a commissioning tool on a valve today. It does only seem to stroke between about 6-9vdc.

    I also monitored the existing controllers that are controlling the Ahu's. They were feeding 4vdc at 0% and 9vdc at 100%. The system is a old Tracer 100.

    So I'm just going to set up my new controllers at 6-9vdc.
