Had some good weather this weekend so I was able to get the Numatics E22 hooked up to the big Numatics air spring. I thought we had a problem the first time I started it up:
Turns out it needs a command signal (verifying with Numatics) anytime the unit is on (probably will make that computer-controlled with a SSR).
Once I applied the command signal it was very responsive with no weight. Didn’t get a chance to load it up yet though.
One other item that I contacted Numatics about was this 1/8″ (?) FNPT port on the back of the unit (side opposite of the readout panel). It leaks air proportionate to the pressure setting. I think it might be for an analog gauge but I wanted to make sure before I plug it.
