3.20.4 Emergency button to retract the i-Drive
The emergency button for lifting the driven castor serves as a safety feature in situations where, for example, the
standard button for lifting stops functioning or the I-Drive battery is fully discharged. The button is in the middle of the
control unit fixed on a holder. The cable runs from the emergency button directly to the driven castor server.
Emergency retraction of i-Drive Power:
1. Press any GO button on the bed.
2. Deactivate the driven castor using the main off switch.
3. Press the emergency castor retraction button.
NOTE: Only use the emergency castor retraction button if the battery is fully discharged or if there is a castor error in
order to push the bed manually to a safe place without use of the driven castor.
3.20.5 i-Drive control unit
The control unit is used to control a special direct current motor (300W, 36V/60uH/0.8Ohm), one servo of the driven
castor (36V, 3A max.), and an electromagnetic brake. It is equipped with an input for a 36V rechargeable battery, an
AC charging source, an input for the "Braked Bed" magnetic switch , and an analogue motor temperature sensor
input.
When the bed is plugged into the mains, the rechargeable battery is charged and the travel functions of the bed are
blocked. After the bed is disconnected from the mains, all the drive functions are available if the rechargeable battery
has been sufficiently charged. If no command is given in battery mode within approximately 3 minutes, the electronics
are then automatically disconnected and minimum energy consumption mode starts. Restart is automatic after
pressing the ON button on the ON/OFF activation panel.
3.20.6 i-Drive power box
The i-Drive Power driven castor is charged from an AC power source . The power box is next the main power box
on the bed's undercarriage frame. The power is supplied by a 3-core cable from the main power box to the i-Drive
Power box. The i-Drive Power box transforms the voltage to approximately 36 V AC (depending on the mains voltage)
and is protected by a current fuse . The power box is then connected to the control unit by a power cable terminated
with a Lumberg connector.
