SIGNAL WORD

Product description

The RolMotion/D+ M-868 is a radio-controlled electronic tubular drive for roller shutters. During operation it executes radial movements.

• An elero assembly cable is not required to start up the RolMotion/D+ 868. The elero assembly cable merely serves to delete end positions or restore the delivery condition. Commissioning of the RolMotion/D+ 868 to configure various functions is performed with the elero assembly cable or an elero radio transmitter.
• The RolMotion/D+ 868 requires fixed attachment points at the top and bottom. A prerequisite is the use of rigid shaft connectors and limit stops or angular bars/concealed stops. There is a relief function for both anchor points.
• If an obstacle is detected, the load is relieved by approx. 1 motor revolution (blind protection with free travel).
• If the same force cut-off occurs after three consecutive uninterrupted movements, the end positions are set (self-learning).
• Cyclical reference runs compensate for changes in the winding behaviour of the roller shutter slats.
• In addition to the usual travel profile (standard mode travel profile), the RolMotion/D+ M-868 drive also has a reduced-speed travel profile (quiet mode travel profile).
• Slow travel when placing the roller shutter slats.
• Slow travel with timed and light-triggered release.

Product contents

Damage to RolMotion/D+ M-868 due to ingress of moisture

• On devices with protection class IP 44, the ends of all cables or plugs will need to be protected from ingress of moisture. This measure needs to be implemented immediately after removing the RolMotion/D+ M-868 from the original packaging.
• The drive must be installed so that it cannot get wet.

Important

In its delivery condition (factory setting), the RolMotion/D+ M-868 will be in commissioning mode.

• The end positions will need to be set (see section 5.6). This action is self-programmed.

Optimal use of the radio signal.

• Extend the antenna as far as possible. If reception is poor, adjust the antenna.
• Do not kink, shorten or extend the antenna.
• Do not position the two radio drives closer than the minimum distance of 15 cm.

Mechanical fastening

Important preliminary consideration:

The working area around the installed drive is usually very small. For this reason, obtain an overview of how the electrical connection has been implemented prior to the mechanical installation (see section 5.2) and make the necessary changes beforehand.

ATTENTION

Crushing or tension will damage the electrical cables.

• Install all electrical cabling so that it is not subject to any crushing or tensile load
• Observe the bending radii of cables (at minimum 50 mm).
• Route connecting cables in a downward loop to prevent water running into the drive.
