MP130-24M Actuators Always giving 10 Volt Feedback.

Hi,

 

I have 10 + MP130-24M Actuators installed on a project. All are giving ten volt feed back no mater what the signal is. The feed back only modulates (10 volts- 0 Volts-10 -Volts) When the reset button is pushed. All cables and signals have been proven. I thought it may have been a faulty one at first but each successive actuator has the same issue. MP500 and MP300 installed all work perfectly.

 

Any ideas on a fix would be greatly appreciated. 

 

Thanks

Re: MP130-24M Actuators Always giving 10 Volt Feedback.

the MP130 actuator with feedback is the MP130-24MP

P for position feedback.

 

You need to first ensure the actuator is mounted on the valve, powered and calibrated. Output X is not correct until the actuator is calibrated.

You may need to reset the actuator for it to re-calibrate, and this reset is recommended if the manual override is ever operated.

There is a small push button on the PCBA next to the Dip-switches that re-sets the actuator.

Hi,

 

Looking at the install sheet, these don't have feedback....unless I've missed something!

 

24Vac

Y = 0-10V or 0(4)-20mA control signal

Common

Re: MP130-24M Actuators Always giving 10 Volt Feedback.

Thanks for the feedback.

 

It looks like what the issue is, I was commissioning the plant before the chilled water was running. Once a pressure was in the pipes and a reset/power cycle was done on the actuator, the valves stroked and started giving the correct feedback. 

 

I am a bit worried that with intermittent loss off chilled water pressure which happens often during the commissioning phases of construction, I may have to run around site and reset this model.
