The CB6S MK2 is part of the LINAK OpenBus™ product range that provides more flexible
solutions no matter which actuator concept is preferred.
It is a powerful control box with Switch Mode Power Supply (SMPS) which is typically used
for applications like hospital beds, couches/tables for treatment and examination and other
medical applications.

Low power consumption
If there is no activity for 2 minutes, the CB6S MK2 will shut down and thereby turn off the lights in all accessories. If any accessories or other devices
activate power request, the CB6S MK2 will wake up again. See the state and transitions diagram of the CB6S MK2 below.
Mains operation:
Mains is connected and full operation is possible. If the CB6S MK2 is charging the battery,
it will stay in this state. All indicators will turn off after 2 minutes, except the charging
indicator.
Mains low power:
Mains is connected, but the CB6S MK2 is shut down to save as much power as possible.
Battery operation:
Mains is disconnected and the CB6S MK2 operates on battery. Full operation is possible
as long as the battery voltage is above approx. 22 V.
Battery low power:
Mains is disconnected and the CB6S MK2 is shut down to save as much battery power
as possible.
The diagram below shows the state and transitions of the CB6S MK2.
Possible combinations
If a mains cable with pigtail is applied, CLASS I is obtained – however the CB label will indicate CLASS II. Eventually, the OEM applying for an
application approval must clarify if such a solution is accepted by the used test house.
Battery operation (standard functionality)
BATTERY LEVELS:
BATTERY HIGH: > 19.6 V - normal
BATTERY MEDIUM: 17.5 - 19.6 V - alarm
BATTERY LOW: < 17.5 V - critical
• If the battery voltage is at ‘medium level’, a battery alarm beeps constantly when activating the hand control/ACx.
(Medium level means that battery charging is necessary to maintain the best possible lifetime.
The medium level battery limit corresponds to approx. 17.5-19.6 V (+/- 5%).
• If the battery voltage is at ‘low level’ (< 17.5 V), 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 the end of stroke.
Crashing the actuator could be a result. The critical level limit corresponds to approx. < 17.5 V (+/- 5%).
• If a battery back-up is applied, it only starts 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 the first use of LINAK batteries, please make sure that they are charged for 24 hours in order to reach
proper function and prolong the battery lifetime.
• The longest lifetime is obtained when the battery is fully charged.
