I Preface
Thank you for your using of CAM888 cam controller, here after is called controller, which is
produced by DUCH automatic technology CO., Ltd. The controller adopts the newest
technology. And our company has the completely independent intellectual property. Besides, it is
the national invention patent product. The characteristics are as following:
zLeading technology
☆It uses the high speed microprocessor, the large-scale field programmable chip and the
entire digital high accuracy high speed control.
☆Gear change system: Intelligent calculate of stopping at top dead end.
☆It is dynamic indicating for cam angle setting, which is more human nature.
zHigh performance
☆The displayed precision of angle measurement may amount to ±0.1°.
☆braking test has 2 channels outputs . programmable scissors cam has 6
channels outputs. Production value has 1channel output.system normal
indication has 1 channel output. Totally 16 channels output.
Before using the controller please read the manual carefully Make sure it is used correctly
and then it will display its high performance. Moreover, this manual is an appendix which is sent
with the controller. Please take care of it after you have used it. So that it will work when you
repair and maintain the controller.
1.1 Notices when open the cases
When open the case, please confirm the following items carefully.
◇If there is any damage during the delivery.
◇Check if the rating value on name plate is the same with your requirement. Make sure the
accessories are whole.
◇Any question please contact us or the supplier.
1.2 Install environment
◇The height is no more than1000m；When it is over1000m, it will reduce the capability of
the controller because of the thin air.
◇Environment temperature：-10℃～+40℃Environment humidity：No more than 50% at
40℃. No more than 90% below 20℃.
◇When the installation base allowable vibration is 10～150HZ, its maximum vibration
acceleration should be no more than 5m/s².
◇Power supply：DC24V1A.

DCH Users Manual U
◇Install a circuit breaker or protecting instrument in the exterior circuit. For safety, the
controller should be fixedly mounted, and the cable should be put in the pipe.
1.3 Warning of installment
◇Never install it on combustible devices. Never put the combustible things beside it. Never
install it in the surrounding which has volatile gas, dust, point-blank sunshine, high
temperature or humidity. Never drop any metal into the controller.
◇Do not disassemble or install the present control by yourself, please reach for the
professional engineer.
◇Please make sure the power line in well condition. If it is damaged or pressed by heavier
goods, it might cause electricity leakage or fire accident.
◇Please make sure the controller is fixedly mounted in the assembly hole to prevent
damage.
◇Keep the control a suitable distance from other instrument.
◇Install a masking means to isolate static electricity, noise signals, magnetic field or
radiation to prevent operation failure.
1.4 Attention of connection design
◇We suggest that you use the DC24V/1A power source. Separate the input & output power
supply from system power supply.
◇Do not put the controller to earth at the same point with motor and transducer. You should
put it in another line. Please ensure that the controller and the press are well earthed.
◇Please install filters at heavy load terminal and inductive terminal to avoid the controller
from being jammed. Please add resistance and capacitance devices to AC contactor and
solenoid valve. The resistance takes 22Ω/2W, the capacitance takes 0.1μF/3KV. Install the
absorb equipment at the side near the contactor coil or the valve coil.
◇The controller cable should as short as possible. Do not put it together with the high
pressure electricity. If it is difficult for you please use metal hose to separate them and put
the AC and DC to earth dividually.
Attention: Putting the sensor wire to earth is extremely important. Please ensure that the
shielded wire of sensor connect wire is well earthed.
