LCA331A Adjustable Tilt Switch for Crane and Lifting Platform Safety

WORKING PRINCIPLE

Above figure is the working principle diagram of the dual-axis , the output is high-low level signal, in this figure, when the tilt reaches the preset value of the positive X direction, X side output high-low level, R1 is lit, when reach the preset value of the Y direction, R2 lit...
Note: Logic level output type sensor, which port drive capacity is limited so it can not drive a big load, if the device less than 500mA power then the switch can directly drive, if over 500mA then can connect to motors, solenoids, relays, etc.for drive ,if need set the relative angle , For setting the relative angle, short circuit the clearing A line with clearing B line in two seconds.

PRODUCT DEBUGGING SOFTWARE
If you want to change the alarm thresholds, can communicate with computer and use the serial debugging assistant software to change .
Your can download the common public serial port debugging assistant software on line, Rion’s products supporting debugging software can connect the inclinometer by itself on computer and display the angle , also can download the public serial port debugging software on line !

Debug process:

1. Open software;
2. Select the corresponding COM port, refer to 2”.
3. Other settings are default setting , no need to set. "
4. Click to open the serial port button, refer to 2 "
5. This data will display in the return data area, refer to 3”
6. If you want to set the alarm threshold, please input setting alarm threshold command in input area, refer to 4" . ( For command please refer to the specification of communication protocol .)
7. When the return data area display " command +Okay" proved successful setting. Refer to 5”

Common problem analysis of connection failure:

• A ) Check power: check positive & negative, whether it is DC?
• B ) Exchange RXD and TXD two data lines re-debugging;
• C ) COM occupancy, close other COM port testing device;
• D ) The black line no connection with the fifth pin of COM port.
• E ) If use RS232 converter, please check if the converter can work properly, whether the driver is installed;
• F ) Please use multimeter to measure the sensor current, if lower than 20mA or bigger than 60mA can judge the sensor was damaged.

TECHNICAL DATA

ORDERING INFORMATION

E.g: LCA331A-P005 : single axis/1 way output/positive output/0.5deg alarm note:

1. Please place order according to the order description;
2. The factory default alarm threshold value is +-2deg, if other value required, please order refer to the order information;
3. The positive ,negative direction expla nation : (positive direction) usually does not alarm, exceed the alarm threshold will output alarm signal ;(negative direction) usually output alarm signal, exceeding the alarm threshold will stop alarm ;
