It specs the reposition resolution.
Honeywell M7284, M7285 & M7294 Modutrol IV™ Series 2 Motors
Astounding, isn’t it, that a primary performance characteristic of an actuator motor, output resolution of the actuator shaft, is a closely guarded secret? You can also find answers to some common questions on our FAQ page. Cross Reference Honeywell, Inc.
I do not see the pots the manual talks about on it. Quick-connect terminals are standard; screw terminal adapter is available. Order Quantity Unit Price 1 – 5 Call for pricing. Images and descriptions may not accurately represent the product.
Adapter bracket for matching shaft height of older motors is available. Honeywell has a higher torque motor, the Herculine series, in a different class. I have a new M in my office and will see how it reacts with different VR3 settings.

The honneywell link I gave was a scanned pdf, whose document number has no other hits on the web. Models available with factory installed transformer, or a field added internal transformer.

This has helped, but not as much as a working valve would! Honeywepl complaint was hunting, where the controller couldn’t maintain setpoint on a belt oven. Fixed torque throughout the entire voltage range.
All models have dual shafts slotted and tapped on both ends. The fast motors were geared lower for speed, the two trade-offs being – the higher the speed, stop to stop, the lower the torque.
I was never able to clarify why the apparent fewer reposition steps. Honeywekl have seen that with pneumatic actuators. Product Data Sheet Coming Soon.

I am going to switch the motors out. Being scanned indicates that maybe it was a draft, most probably is no longer current and is obsolete? The ideal cotnrol position was in between motor reposition-steps. But I’ve seen first hand the effect of an acuator that can not resolve sufficient positions to control a gas valve. I tend to m77284 for Kromschroder GT motors, GT31 usually and GT50 for bigger valves, they do a good range of different supply voltages and travel times and the end of goneywell and signalling limit switches are easy to adjust.
Usually Ships in 1 – 3 Weeks. Ill let everyone know how much more accurate it is.
We’ll keep you connected! So it follows that your motor doesn’t have the adjustment. There are 4 ‘enhanced’ Modutrol IV models, all of which are mA proportional motors, each of which has more than 55 repositions.
It took 3 calls to find someone willing to research this. The current web page for the Mx motors is http: Integral auxiliary switches are available factory mounted, or can be field hlneywell.
