Cabin Interface Module (CCIM)

            

The Model6206 CAN Angle and Length Module is designed as a small all-in-one unit for measuring angle and length in industrial lifting applications. The unit has been designed to fit onto the outside or inside of a telescopic boom. With its small footprint, low profile and M12 screw lock connector system; makes it easy to install. The CALM uses unique quadrature encoding for the length measurement and solid state accelerometers for angle determination; making the unit fully digital and self calibrating. The boom length input is required by the load/rating processor to determine the boom position (in order to calculate the load and rated capacity). The internal recoil spring is protected against reverse recoil in the event of trace cable breakage via an internal clutch mechanism.

The boom angle sensor is used to measure the machines boom angle with respect to gravity. The input of the sensor is required by the load/rating processor unit (to determine if the safety cut-out needs to be activated).

The boom stow position is measured to aid logic analysis of the sensor state for advanced mechanical fault detection. Low power detection saves the current length data in two separate EEPROM locations (in both normal and inverted formats). This length data is used to recover the boom length at next machine start up. If the low power input incorrectly triggers or fails, it will force the processor to be held in reset (producing an off-line fault in the NPU).

Model6381 CAN Dual Inclinometer Module (CDIM)

The Model6381 CAN Dual Inclinometer Module is a multi functional sensor/system used for determination of relative angles with respect to gravity. The CDIM can be used as a sensor with the EQSS SFPL and Gen3 product range, or as a stand alone system in applications such as chassis level or man basket level (maximum angle alarm or cut-out requirements). The CDIM uses state of the art solid state dual axis inclinometers that provide high accuracy in all operational environments. This sensor is factory configured to suit the application as either a system sensor or an angle limiting system where audio and electronic outputs are required. The CDIM is enclosed in a durable IP67 rated enclosure and electrical connections are made via a durable M12 screw lock connector system.

Model 6231 CAN Light Tower Module (CLTM)

1. The system is constructed with established and proven methods of design, construction, material selection and QA validation. In accordance with the Analogue and Digital Measurements QA programme. All system components/nodes are designed and constructed for the specific application and environmental conditions for use with EWP's and industrial lifting equipment.
   
2. All components produced are designed for their specific application and environmental conditions. During design, all foreseeable failure points are considered and eliminated taking into account variables such as stress strain and mechanical ware.
   
3. Other manufacturers components that are integrated into the component/nodes of the system are designed in (based on their specification and quality levels). Each component that is integrated, is operated in accordance to the manufacturers specification.
   
4. All digital output controls are designed to be fail to safe; such that when in the de-energized state, the safety function is active. All digital input channels also use the de-energized principle such that in the event of a failure, the digital input is sensed as high.
   
5. Limitation of the generation and/or transmission of force and similar parameters. This is considered in all mechanical system components.
   
1. for example: the length transducer incorporates an internal clutch such than in the event of a drawer wire breakage, the inertia caused by the spring recoil will not damage the recoil spring.
   
6. The SFPL is designed to operate from -20 to +85 degrees C. This is made possible by the correct selection of electronic components.
   
7. In the event of an unsafe condition, system(s) failure or system(s) fault the SFPL will activate the safety cut-out within 750ms.
   
8. All electronic nodes have built in reset controllers such that each node starts up at the same time. The system does not store energy and can not continue to operate for greater than 5ms without power.
   
9. The system is designed to be modular with the least number of system nodes and I/O signals required (thus reducing complexity and increasing reliability).
   
10. All components are well protected against environmental exposure. For example the display module is encased in an IP69 enclosure.  

1. All components and materials used in the Model6277 SFPL are selected to enable the system to operate with its maximum operational specifications and to insure long life and integrity of the system.
   
2. All critical components used within the system have known failure modes as detailed within the device component data sheets.
   
3. All mechanical and electronic components are designed to operate above the system design specifications.
   
4. All electro mechanical, and mechanical systems are held a safe operational position, non reliant on frictional forces
