Intelligent Motor Control Units (discontinued itm)

230 V, for flush-mounting

The intelligent motor control units allow for automatic or manual control of 230 V drives of shadings or windows. For that purpose, the devices have got inputs for central control and for push buttons.
The push button input for unlocked buttons is equipped with an automatic key timer, that differentiates between brief and longe button pressure (step mode, autohold). The push button input of the IMSG 230 is designed for 230 V AC, the MSG1-UP for 8...28 V.
The up/down central command input of the IMSG 230 expects 230 V AC, for example of switches, timers or of control systems like Solexa, Arexa, WS1 or WS1000. Signals at the central command input have got priority.
The central command input of the MSG1-UP works with voltages between 8...28 V. This input, too, is suitable for timers, push buttons or controls. It can be set to deadman or autohold modes. The relay of the MSG1-UP motor output is a low wear zero voltage switch.

Motor control unit IMSG 230 V:

  • Use as a central, group and single controller
  • Central input up/down 230 V (with priority) e.g. for switches, Solexa control system, Arexa control system, WS1000 conservatory control systems
  • Manual operation by connecting an unlocked double push-button.
    Push-button timer automatic: Inching mode (press for less than 1 second): Drive inches, for example for positioning slats on shutters.
    Drive mode (press for longer than 1 second): Drive travels automatically to the final position
  • Storing a drive position using the manual switch, can be recalled by pressing the down button for a longer period (3-6 seconds). A position of a shutter or a partially opened window that is often required can thus be set quickly with no effort
  • Direction change pause 1 second

Motor control unit MSG1-UP:

  • For a 230 V drive (Up/Down)
  • Input for central control
  • Input for manual operation
  • Setting the central control unit to "Dead man" or "Lock". As long as voltage is present at the central input, the manual operation is blocked
  • Direction change pause 1 second
