Part didn't come in till 430pm. Arrived onsite at 5pm. Installed CPI card and gate malfunctioning even more. By adding the client card we added a device drawing voltage. Took device off and issue went away to normal operation. Tested 3 phase incoming power and we have 206VAC. Tested the 24VAC terminals going into the board from the transformer and had a resting 22VAC and under load it has 20.7VAC. This indicates a pre-existing bad transformer that is now on the edge of supplying enough power to motor. Thus the intermittent failure in both up and down motor directions. The devices added to make gate automated for cars don't draw enough power to normally affect the motor operation. The transformer output should normally be about 27VAC. We will need to order the transformer and disconnect power while doing so. No service disconnect so the breaker must be turned off while working. We HIGHLY recommend having a 3 phase service disconnect on the wall installed before the motor. This is not
