Due to its internal construction, the housing fullfills an essenti-
al requirements for the installation of the drives. Especially the
easy assembly/dismounting of the battery and electronic by sta-
ble holding sheets characterize this dual drive. The dual drive can
be combined with any ILCON motors. The dual drive disposes of
a mains isolation and an emergency lowering device.
4.2.2 The mains isolation
The integrated ILCON-mains isolation in the mains plug provi-
des, besides a high safety guarantee, many practical advantages
when in use. In the net free mode, the mains isolation prevents
any magnetic and electric AC fields in the bed. The mains isola-
tion is self-contained and requires no additional transformer for
its stand-by. With the drive working in disconnected mode, no
energy is consumed and a switching sound in the relay serves
as indicator of the correct operation. The mains isolation is com-
patible with superordinate mains isolation.
The ILCON-mains isolation in the mains plug can be activated
at the touch of the button on the hand control. A direct current
loaded capacitor in the drive conducts current to the double-
pole relay in the mains connection and activates the transformer
whilst the drive is in use. In this process, the capacitor is being
reloaded in order to be ready for the next actuation. Everytime
the hand control button is being let go, the mains is discon-
nected from both poles by the relay. A switching sound indicates
the performance of this function.
The 9-volt battery for the emergency actuation which is a stan-
dard installation in the control, buffers the capacitor of the mains
isolation for the case of need, if it has not been used for a lon-
ger period and has,therefore, lost its voltage. Should the capa-
citor and the 9-volt
buffering battery be used up, it just takes a touch on the green
button so that the mains isolation starts working as usual again.

Once a year the 9 Volt bat-
tery of the motor should
be tested and if necessary
exchanged. Furthermore
regular visual inspections
should be done.
