The MC800 is an electronic control unit designed for automating swing gates. It is specifically configured for connection to devices within the Opera System and Bluebus system. Additionally, it supports accessories that utilize an "SM" connector.
Function Description
The control unit manages the operation of two 120/230 V~ 50/60 Hz gearmotors, facilitating both opening and closing movements of swing gates. It incorporates various inputs for command devices (step-by-step, open, close), safety devices (stop, photocells, sensitive edges), and limit switches. The control unit also provides outputs for a warning light, electric lock, and an "Open Gate Indicator."
Key functions include:
- Automatic Closing: After an opening maneuver, the gate automatically closes after a set pause time (default 30 seconds).
- Close after Photo: If photocells are triggered during an opening or closing maneuver, the pause time is reduced to 5 seconds.
- Always Close: In the event of a power outage, the control unit detects an open gate 10 seconds after power is restored and initiates a closing maneuver, preceded by 5 seconds of pre-flashing.
- Ramming Function: A brief closing maneuver is triggered before opening to facilitate unlocking of an electric lock.
- Warning/Courtesy Light: The warning light output can be configured to function as a courtesy light.
- Pre-flashing: The warning light can flash 3 seconds before a maneuver starts to signal a dangerous situation.
- "Close" becomes "Partial Open 1": The "Close" input can be reconfigured to trigger a partial opening.
- Pressure Maintenance: For hydraulic motors, a brief closing maneuver is triggered every 4 hours (if the gate has been permanently closed) to reload hydraulic circuit pressure.
- Move Anyway Function: Allows operation of the automation even if some safety devices are malfunctioning, by holding down the control command.
- Maintenance Notice Function: Signals to the user when maintenance is due via a lamp connected to the "OGI" output.

Usage Features
The MC800 offers flexible programming through two levels:
- Level 1 (ON-OFF): Allows enabling or disabling of core functions like automatic closing, close after photo, always close, ramming function, warning/courtesy light, pre-flashing, "Close" becomes "Partial Open 1," and pressure maintenance.
- Level 2 (Adjustable Parameters): Provides fine-tuning for parameters such as pause time (5 to 180 seconds), step-by-step function sequence (Open-Stop-Close-Stop, Open-Stop-Close-Open, Open-Close-Open-Close, Condominium modes, Hold-to-Run), opening delay (0% to 50% of work time), closing delay (0% to 50% of work time), balancing (0% to 100% closing duration adjustment), motor force (25% to 100%), start-up time (0s to 3s), and pedestrian/partial opening levels (1/4, 1/2, 3/4, full opening of M2 leaf, or 1/4, 1/2, 3/4 of minimum opening level for both leaves).
Learning procedures for mechanical stop positions can be automatic, manual, or mixed. The control unit automatically recognizes connected Bluebus devices and devices on the "Stop" input.
Maintenance Features
As an electronic part, the control unit itself does not require special maintenance. However, the overall automation system should be regularly checked (at least every 6 months) to ensure efficient operation. This includes verifying the proper functioning of safety devices (photocells, sensitive edges) and checking for any installation or adjustment defects. The "Maintenance notice" function can alert users when service is due. Only qualified personnel are authorized to perform checks, maintenance, and repairs. Before any maintenance, the motor must be manually unlocked to prevent accidental gate movement.
