CB6S Phased-out products | 62 CB6S is part of the LINAK OpenBus™ product range - that provides more flexible solutions no matter which actuator concept is preferred. Mounting of CB6S – article no. 9271233 Apart from LA27 and LA40, it is not possible to mount CB6S onto LINAK actuators. In such case you need a CB6 mounting bracket which can be welded or likewise to the application. This bracket is shown below: 28.25 22 6.8 17 13.15 17.8 80 11.5 6.8 40 35.8 12 14 85 128.3 Warnings Thermal protection - OBF only The CB is equipped with a thermal protection to avoid thermal overload of the FET transistors used to control the acuators. When triggering the thermal protection all movement of the actuators will stop and the buzzer will sound for 5 seconds constantly. The 5 second alarm will be reinitiated each time the handset/ACP or similar is activated until the CB is cooled down enough to allow a movement again. The thermal monitoring system monitors a temperature rise and not an absolute temperature. The monitoring system has been designed to operate up to an ambient temperature of 40 degrees. If the CB is exposed to a temperature higher than 40 degrees for several hours while powered it will adapt to this temperature. In this case there is a risk of damaging the FET transistors without triggering the thermal protection. At first power up, after programming a new SW into the CB, the ‘temperature reference value’, used by the thermal monitoring system, will be automatically initialised. If this is done in a cold area the temperature reference value will be set accordingly and a too early temperature warning could occur (warning signal is temperature hoot = constant beep)! After the first power up, the temperature reference value will adapt over time to the surrounding temperature and the adaptation routine happens every 5 hours (provided the CB is unused and connected to mains). The 5 hour counter (used by the temperature adaptation routine) will be reinitiated every time a handset/control panel is activated. We therefore recommend that the CB is resting for min. 5 hours to adapt temperature wise to a ‘normal operating’ temperature, i.e. in the environment for intended use.

Phased-out products | 63 NOTE - HOT PLUGGING Removing or adding any OpenBus™ cables is not allowed when the CB is powered by mains supply! If needed anyway, follow the below procedure: 1. Remove mains and wait 5 sec. 2. Mount or dismount the required cables If this procedure is NOT followed, it may result in a damaged OpenBus driver circuit. The risk of a damaged circuit increases if the accessory has a high start current (in rush current). OBF - hot-plugging protected from January 2016. Battery operation OBL and OBF: • If the battery voltage is at ‘low level’ a battery alarm beeps constantly (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%). • The CB6S with battery back-up 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 24 for 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 CB6S is powered by mains voltage: At no operation of the HB the backlight in the HB is dimmed. 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. • When CB6S is powered by battery: At no operation of the HB there is no backlight in the HB. If a HB button is activated the backlight illuminates fully. When the HB button is released the backlight turns off. 1ST FAILURE SAFE MONITORING: OBF More information about ‘OpenBus™ SW guidance’, please contact your local LINAK department. Mounting of LA27/LA40 on OBF is not recommended because of the big toroidal transformer used.
