What to do if master gate closes first and the slave gate stops on PowerTech PC170 Control Panel?

If, on your PowerTech Control Panel, the master gate closes completely before the slave gate stops, and the flashing light blinks rapidly for five seconds, try this: cut off both the AC input power and the battery output. Manually release both the master and slave gates. Then, by hand, fully open the master gate and fully close the slave gate. Finally, restore power to the unit by reconnecting the AC and battery terminals.
