Duty cycle
The maximum duty cycle of the electrical couch functions is indicated on the type plate and in the technical data
(see 1.6 Type plate and 9.4 Technical data).
NOTE
10 % 2 min. / 18 min. means that each electrical adjustment may be operated continuously for a
maximum of 2 minutes and then a pause of 18 minutes is required (overheating protection).
TIP
The couch is equipped with a self-resetting thermal protection device, which prevents an overload
of the control unit or the adjustment drives. The couch is automatically switched off in the event
of overloading.
If the maximum duty cycle of two minutes is exceeded several times or for an extended period of
time, the electrical adjustment functions are temporarily unavailable.
The couch has been adjusted again once it has cooled down sufficiently.

Battery mode
The couch can also be equipped with a battery (lead gel) for shock position (Trendelenburg position). This means
that in the event of a mains failure or if the couch is disconnected from the mains, the patient can be quickly
brought into the shock position independently of the mains supply.
The battery is not intended as a replacement for mains operation.
Notes on handling the battery
TIP
Charge the battery for at least 24 hours before first use.
The battery is then available for emergency operation without restriction.
It is not possible to overcharge the battery.
The couch can be adjusted during the charging process.
NOTE
Proper handling increases the service life of the battery.
Avoid deep discharge of the battery.
Deeply discharged batteries can be damaged to such an extent that premature replacement is
necessary.
In order to guarantee the electrical functionality at all times or the longest battery life, the couch
should be connected to the mains at all times.
Fully charged batteries should not be stored for longer than 3 months without recharging. The
battery must be fully charged or replaced with a fully charged battery every 3 months at the lat-
est, otherwise it will be damaged due to self-discharge.
The battery (accessory) in the control unit is a wearing part and must be replaced after 4 years at
the latest, or even earlier, depending on the intensity of use.
Frequent and fast discharges reduce the service life of the batteries.
The control unit distinguishes between three charging levels:
Charge level high:
> 20 V
- Normal
Charge level medium: 18-20 V - Alarm
Charge level low:
< 18 V
- Critical
If the charge level falls to the medium voltage (18-20 V), a permanent alarm sounds as soon as any key of the
hand control is pressed. The battery should be charged immediately to ensure the best possible service life.
When the charge level reaches the critical level (< 18 V), the control unit immediately deactivates all movements.
If you still try to move the couch by pressing a button on the hand control, the battery can be deeply discharged.
There is a danger that the initiated movement cannot be finished or that the processor in the control unit can no
longer detect the position of the drives. The longest life span is achieved when the battery is fully charged.
