Emergency lowering function: (optional)
Emergency lowering is meant for lowering the bed if a power failure occurs and the bed needs to be driven down into
horizontal position.
The internal motors in the TD3 and all external motors connected can run in a random order depending on which button
is activated on the handset. When the synchronous drive/reset button on the handset is activated, the system will run in a
sequence running the internal motors first and then the external motors. The default sequence of the emergency lowering
is backrest => leg rest => headrest. If more external motors are connected, they will not run by activating the synchronous
drive/reset button, but only if the belonging button on the handset is activated. If the system does not work as described
above, the setup is not standard.
Please observe that all motors will be driven singularly.
Emergency lowering after 2 hours (disconnection of mains):
If a power failure or a disconnection of the mains continues for more than 2 hours, the TD3 will go into a hibernation mode.
When the TD3 is in hibernation mode, the bed can only be activated by activating the reset button (see page 15) on the TD3.
Keep the button pressed or use the handset to drive to horizontal position.
Mounting of the accessories:
All 3 types can either be mounted on the bed using screws OR simply slide the unit(s) onto the groove on the TD3. The
mounting screws must be fastened with a max. torque of 1 Nm.
For mounting on the bedframe: use wood screws (M4) with a maximum head diameter of 8 mm, and a suitable length.
If several units are used in a system, they can be stacked/mounted on top of each other, taking up a minimum of space.
Please observe that the HC20RF is delivered without batteries. Batteries can be ordered as a separately article number
0063018 (4 x AAA).
