Terminal 69 extends from electron plate 14.
Then, it is DC but non-constant low-tension current distributes to current rectifier 71 along the direction of arrow 74.
" low pressure " refers to the voltage lower than 100 volts.
Rectifier 71 is suitable for AC voltage being converted into D/C voltage.
During software configuration, rectifier 71 rectifies without changing it D/C voltage.
After rectification, electric current flows to filter condenser 72 along the direction of arrow 75.
Capacitor 72, which is suitable for filtering output voltage signal, keeps constant voltage signal power supply, but for matching
Operation is set, transmits voltage signal with not being changed.Therefore, electric current reaches microprocessor 73 along the direction of arrow 76.
Microprocessor 73 is suitable for measuring and decoding voltage signal, and according to the sequence received, setting is normal for electrodynamic pump
The correct software configuration used.
For power supply, microprocessor 73 is measured close to constant D/C voltage, and is interpreted simply as power supply.
On the other hand, for configuration, microprocessor 73 measures the non-uniform D/C voltage gradually increased, and is construed as
Configure signal.
For configuration, the initial initiating sequence for continuing 200 milliseconds applied according to following table:
| Time [millisecond] | 0 | 50 | 100 | 150 |
| Voltage [volt] | 30 | 40 | 40 | 50 |
Then apply the sequence for depending on the configuration to be arranged.
Configuration sequence is for example made of eight periods.
Possible sequence only gradually increases voltage, in this way, withouts waiting for any electric discharge of DC route.
In this example, there are 164 possible sequences.
Each sequence is described by hexadecimal number, wherein every two voltage values represented between 60V and 90V.Binary number
00 corresponding 60V, and the corresponding 90V of binary number 11.Highest two of the binary number of sequence are described, i.e., it is two leftmost,
Represent the first voltage applied.Minimum two of the binary number of sequence, i.e. the two of rightmost are described, the last of application is represented
Voltage.
For example, hexadecimal number 01BF, is equivalent to binary number 0000000110111111, correspond to 60-60-60-70-
The sequence of 80-90-90-90, unit are volt.
Once configuration sequence terminates, electrodynamic pump 10 is powered by the AC voltage (such as 230V) for using, and is tested
Continue.
