Definitely need the packing kits for these actuators. They are leaking like a sieve!
M2d is installed. From the factory they come set for 0 to +10 VDC with the closed position at +5 VDC – I had to change the DIP switches after I had it installed (note for future installations) to work with -10 VDC to +10VDC so that 0 VDC is our closed position. One question is whether or not that 0 VDC can be “floating” for short periods of time.
I didn’t have any weight on the platform (only 380 pounds) but because of the leaking I couldn’t continue with the tests. However, when the pressure in the actuator exceeded 30 PSI or so the seal “locked” and it was quite strong – all my might I couldn’t get it to budge (which is really promising).
