Description of operation

When power is supplied to the control units, the relays are off; consequently, both motor wires are connected to the same power supply terminal.

It is possible to send a command to an individual motor via inputs 1 and 2.

Multiple units can be grouped together by connecting all inputs 3 and 4 to one another (see diagram). Each control unit can send commands to the others via this BUS; furthermore, the group can be controlled by adding 2 push-buttons (see diagram).

Link multiple groups together by connecting inputs 5 and 6 of a control unit in each group. Each control unit can send commands to the others via this BUS; additionally, the group can be controlled by adding two extra push-buttons (see diagram). 

Operation of the Up/Down buttons

• Short command while the motor is stopped: a brief press of the local Up/Down button triggers the full movement of the motor until it reaches its limit switch or the maximum set time (default is 30 seconds).
• Short command with the engine running: a brief press of either of the 2 buttons stops the engine.
• Extended operation with the motor off: moves the motor until the button is released
• .Extended command while the motor is running: if it is in the same direction, it has no effect. If it is in the opposite direction, it stops the motor and then restarts it in the opposite direction.
• Stop all motors: pressing the Up/Down buttons simultaneously stops all motors, regardless of how they are grouped or at what level they are positioned.
• Operating all motors in the group: By pressing both the Up and Down buttons simultaneously and then releasing the button for the UNWANTED direction, you will send a command to all motors in the group. If you continue to hold the button down for an additional 3 seconds, the motors on the level above will also be activated.

Group button

• Controls for all motors in a group: a short press triggers the full movement of all motors in the group, continuing until they reach their limit or the maximum allotted time (30 seconds).
• Stop all motors: pressing the Up and Down buttons simultaneously stops all grouped motors.
• Controlling the motors of all groups: By pressing both the Up and Down buttons simultaneously and then releasing the button for the UNWANTED direction, you can send a command to all motors in the group immediately, without having to wait for the 3-second delay.

Programming the maximum movement time

1. Position the motor at its limit—either 'Up' or 'Down'.
2. Pressing and holding the Up and Down controls simultaneously for at least 6 seconds enters programming mode, which is indicated by a short, chirping signal from the LEDs that show BUS activity.
3. Releasing the button for the unintended direction initiates movement, and the BUS indicator LEDs begin to flash once per second; for the first 2 seconds, only one of the two LEDs flashes, indicating that the duration is too short. From the third second onwards, both LEDs flash.
4. Releasing the button—or pressing the other one—exits the programming mode, and the movement time is permanently stored, even in the event of a power loss.

NB: Agendo sui pulsanti locali si imposta il tempo del singolo motore. Agendo invece sui comandi di gruppo, si imposta il tempo per tutti i motori del gruppo. Utilizzando i comandi di raggruppamento totale, si programma il tempo su tutti i motori Su/Giù.
