The CB6 OBMe is a powerful control box with switch mode power supply typically used for
applications like hospital beds, couches/tables for treatment and examination and other medical
applications. The universal input voltage makes the control box adaptable to the world-wide market
irrespective of the input voltage.
Approvals:
CB6 OBMe is approved according to UL60601-1 and EN60601-1.
Possible combinations.
CB6 OBMe is meant for use with:
LA27 std. motor (cable type ‘B’),
LA27 std. motor (cable type “A” = encoded) with / without Hall
LA31 std. / fast motor with / without Hall,
LA34 std. / small / fast motor with / without Hall (fast motor not max. load),
LA44 std. / fast motor with / without Hall (fast motor not max. load),
BL1 (only with +35% transformer type) with / without Hall,
HB7x, HL7x, HB8x, FSE/FSL, FS2, MJB, DJB, ACO, ACC, ACK.
CB6 OBMe – with transformer has been approved for CLASS I operation incl. CLASS I cables
(without pigtail for earth).
CB6 OBMe – with SMPS is not approved for CLASS I operation, basically because of the design of
the housing. However the PCB contains 2 x fuses (phase, neutral) as required for CLASS I operation.
If a mains cable with pig tail is applied CLASS I is obtained – however the CB label will indicate
CLASS II! At the end of the day the OEM user applying for an application approval must clarify if
such a solution is accepted by the used testhouse.
Recommendations:
Battery Operation:
• If the battery voltage is at ‘low level’ a battery alarm beeps constantly by activating the HB/ACx.
Low level means that battery charging is necessary to maintain the best possible lifetime.
Low level battery limit corresponds to approx. 19 V (+/- 5%).
• If the battery voltage is at ‘critical level’ the battery alarm function shuts down all operation immediately.
If trying to operate the system anyway, the battery could become deeply drained or the actuator system could be damaged.
When at critical battery level there is a risk that the processor will incorrectly monitor end of stroke. Crashing the actuator could be a result.
Critical level limit corresponds to approx. 17.5 V (+/- 5%).
• If battery back-up is applied it only commences battery charging when it is connected to the mains.
• A battery stored at 25° C has to be recharged every 6 - 7 months.
• Prior to first use of LINAK batteries, please make sure that they are charged for 24 hours in order to reach proper function and prolong
the lifetime of the batteries.
• The longest lifetime is obtained when the battery is fully charged.
If Backlight supported HB is used:
• When CB6 OBMe is powered by mains voltage:
- If an HB button is activated the backlight illuminates fully. When the HB button is released the light is dimmed again after approx. 10 - 15 sec.
Backlight turns completely off after 2 min.
Exception: While charging the HB backlight will stay on dimmed until charging is finished.
• When CB6 OBMe is powered by battery:
- If a HB button is activated the backlight illuminates fully. When the HB button is released the light is dimmed again after approx. 10 - 15 sec.
Backlight turns completely off after 2 min.

Failure safe monitoring
Is made in two ways on the OBMe platform. It may be difficult to observe the LED status (hardware) if CB6 OBMe is placed under
a bed, therefore it is now monitored by software as well.
• CB6 OBMe is equipped with a 1
st
Failure safe indication controlled by HW (power request). At normal operation (no failure observed) the power
LED turns yellow when a HB button is activated.
