Product description

The IMSG-UC-4H motor control unit allows four 230V drives to be controlled. The unit
offers the possibility of operating the connected motors via integrated buttons or
manually via up/down hand switches.

Functions:

• For four 230V drives (Up/Down)

• With key pad (manual operation) and status LEDs

• 4 hand switch connections (extension inputs) for unlocked double button

(manual operation on the spot, can be set to Standard or Comfort mode)

• Central and extension inputs with variable voltage (6…80 V DC, 6…240 V AC)

• Setting the central control unit to “Deadman” or “Latch”

• Commands at the central and button inputs have the same priority

• Storing one movement position per drive

• Pause to reverse direction 1 second, motor runtime 240 seconds

• Connect through clamps

• Potential-free relays

Central operation

The central input of the IMSG-UC-4H allows, for example, an automatic control unit, a
timeswitch or a normal, unlocked double button (Up/Down) to be connected. The central
command (continuous voltage) always has priority over a movement command from the
extension inputs.

LED signals during central control (continuous voltage):

During movement: Channel LEDs in the direction of movement flash every 2 seconds

Runtime reached: Channel LEDs in the direction of movement continue to flash

every 2 seconds

If there are “Up” and “Down” movement commands at the central input at the same
time, the drive moves up (secure position).

The central control unit can be set to the operating modes “Latch” (default) or
“Deadman”. You can switch between the operating modes using the following buttons
integrated on the device:

Press the

button of channel 1 and the button

of channel 2 for 5 seconds at the same time

If the Latch mode is active, the Network LED is on. If the Deadman mode is active,
the Network LED flashes every second. Change the operating mode by pressing
(channel 1) and

(channel 2) again.

Individual operation

Manual individual operation of the drives can take place via the integrated Up/Down
buttons at the device or via unlocked double buttons (extension inputs). The movement
mode can be stopped via both buttons (

Manual operation can be set to “Standard mode” or “Comfort mode”:

Standard mode (default)

• If a button is pressed for less than 1 second, the drive will move in a step-by-step

fashion. This allows, for example, slats to be positioned precisely.

• If a button is held for longer than 1 second, the drive moves to its final position

(switching off after 240 seconds of maximum runtime)

This is how you set the Standard mode:

• Press the

button on the channel to be set for 5 seconds and then additionally the

button for longer than 1 second

• To confirm the On LED on the channel flashes 5 times

Comfort mode:

• If a button is held for less than 0.3 seconds, the drive moves to its final position

(switching off after 240 seconds of maximum runtime)

• If a button is held for longer than 0.3 seconds, but less than 2 seconds, the drive

moves only while the button is pressed and stops immediately when it is released
(deadman function)

• If a button is held for longer than 2 seconds, the drive moves to its final position

(switching off after 240 seconds of maximum runtime)

This is how you set the Comfort mode:

• Press the

button on the channel to be set for 5 seconds and then additionally the

button for longer than 1 second

• To confirm the Off LED on the channel flashes 5 times

Individual movement position

The IMSG-UC-4H can store one movement position for each connected drive. This allows
fast and uncomplicated movement to a position that is needed often (e.g. a shutter
position or the partial opening of a window).
