Turn the 120Vac power off then gate opens automatically. Note: All devices wired to the DC2000™ MUST be dedicated to it alone. Normal operation will be controlled by separate devices wired to the OmniControl™ board and surge suppressor. Typical Auto Mode Example: If the DC2000 is "automatically opening" the gate due to a power failure (auto mode), any manual command such as "One-Button", "Three Push Button", "Key Switch", "Photoelectric Sensor" or "Edge Sensor" will cancel the automatic mode of the DC2000™. After such cancellation, the DC2000™ will continue to operate in "manual mode" until 120Vac power is restored.
