I just purchased a sms122 and ma957 regulator. my problem is that if i plug the power plug for the controller on to a power strip with anything else on it the solenoid will switch on when the sms122 turns it on(lite blinking) but when it shuts off the solenoid does not release.(meaning my co2 keeps running) If i plug it directly to the wall outlet it works ok. kinda weird. I called milwaukee and left an email any ideas? Am I doing something wrong?
