Cb6S Mk2 - Linak Inline LA20 User Manual

5. CB6S MK2 (MEDLINE CARELINE
®
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 .
