Battery Operation
In an emergency, rechargeable batteries are used to operate the electrical drive
system independently of the mains supply. This guarantees that all electrical
adjustments can be carried out during a power outage.
Emergency operation
-
When the bed is occupied by a patient of normal weight (approx. 80 kg),
adjustments can be made for approx. 6 to 10 minutes if the battery is new and
fully charged.
-
Under emergency conditions, if the battery capacity is depleted, an alarm will
sound as a warning during adjustment.
If the battery charge drops below 10%, all adjustment functions are
locked in order to prevent the batteries from discharging their entire
charge, as this could shorten the battery’s life.
In this case, take the following action to optimise the battery life:
-
Plug the bed into the mains power supply as soon as possible to
recharge the battery
-
If the bed is not plugged into a mains electricity socket, avoid
attempting repeated motorized adjustments that would discharge
the battery even more
Charging the batteries (charging time)
-
The batteries are fully charged when the bed has been connected to the
mains supply for at least 8-10 hours. See Chapters 4.2.5 and 4.2.6.
-
It is impossible to overcharge the battery.
-
During the charging process, the bed can be adjusted using the handset or the
control box.
-
The batteries have a limited service life. In normal use, this service life is approx.
five years. The batteries need to be replaced when operation cycles become
very short. For safety reasons, at least one more height adjustment (up + down)
should always be possible under normal load. Otherwise, the batteries must be
replaced.
-
In this case, contact Stiegelmeyer’s customer service. We will replace the
rechargeable batteries and dispose of the old batteries properly (see page 61
for the address).
