Ok, those of you that know my posts know that I usually donít ask for much help. I mostly read and learn from you guys.
But there comes a time when you just have to ask for help and these are just one of these times.
Iíve been trying to get Belimo PWM LF 24 mft us, 150sec stroke, p2002 (60 units to be exact) actuators to work with INET 2K, MRAHU (asc device). Iíve been working with the air balancing company to finish this job but I canít get the m and b values correct.
The specs. call for p2003 actuators so I think they were pre ordered with a specific configuration.
Our guy who has all the look up tables and values is being a dik and will not give me his info.
(Personally he is scum and scared someone can do his job better than him, he does this to every one. He is management to boot).
So here I am left, to my own devices to find the answers. I ordered the Belimo hand held and computer software yesterday and it wonít be in until late next week.
I need to 1. pulse the actuator to full open and then close again based on ODA.
2. The AI pulses the actuator open but the close value must be wrong because I canít seem to get it to pulse in short enough pulses. The Belimo info states a .59 sec pulse to move closed but have you ever tried to time that? I know I canít, so with that in mind and the fact I set up a test ASC and using my laptop Iíve been working on getting the right values. The m and b values I have are limited and canít seem to get it right.
If any one can help I could really use it.
Thanks for your time.
