1.8. Prohibited items on fire and smoking. Absolutely avoid use of a encoder beyond its rated range becouse doing so may couse a fire. If misuse or abnormal use may result in conditions in whith the encoder is used out of its rated rang. Take proper measures such as current interruption using a protective circuit.
The grade of non flame ability for resin used in encoders is “94HB”.Which is based on UL94.
Standards(flame ability test for plastic materials). prohibit use in a location where a spreading fire may be generated or are pore against a spreading fire.
2.9. For use in equipment for which safty requested.
Although care is taken to ensure encoder quality.
inferior characieristlcs. short circuits.
open circulis are some problems lhat might be generated.
To design a set which places maximam emphasis on safety. Review the offect of any single foult of o encoder in advance and perform virtually fail safe design to ensure maxlmum safety by:
•preparing a protective circuit of a protective device to improve system safety and
•preparing a redundant circuit to improve system safety so that the single fault of emcoder dose not cause a dangerous situation.
3.Reliability
The item designed mainly corresponds to JIS(Japan Industry Standard) on the reliability conditions.
4.Software treatment
This product composes that when the only center switch turned on. SW E may turn on and when two leaning switches and the center switch turned on. SW A-D may turn on.
But this product may respond as fellows. Please make software-control so as not to cause problems for use.
(1)When making push operation with the knob leaned. SW-A-D may turn on.
(2)When a shaft is leaned to 45° direction against X-Y direction. Only one leaning switch or three adjoining switches may turn on.
(3)As with switching operations in relation to other operational directions. Use it with the conditions free from problems after confirming response sing our company.
5.ESD solution:
Connecting the terminal 7 with GND for ESD solution.
6. This production is not dust proof type.
Please consider the dust proof at your application design.
7. Please avoid adding the drop impact directly to this product.
