I am currently troubleshooting an odd issue with a set of actuators on a small CRAH unit. After thorough investigating my problem points to a device issue but I find it nearly impossible that all 3 of the actuators have the same exact issue. The model numbers in use are, AFRB24-SR and AFB24-SR-S. I am currently sending 2 volts to the control side and receiving 4 volts back. There doesn't appear to be an issue with the 24v power supply and this has me scratching my head. Has anyone seen a problem like this?
