SC8207 improved nature wind and sleep wind mode except hold the traditional fan functions, and improved two groups of swing control and light control function. SC8206 cooperate with SC5104 encode IC, implement the remote control of the fan. “OFF” key: It used to shut down the power of motor, fan stop operating. And the control circuit resume static state, and stored the operate mode of power on. When started next time, it is activated into the operation mode stored in the operation memory (Timer and sleep wind mode will not be stored). “ON/SPEED” key: It start fan if pressed when fan is off. It turn on the fan with middle wind for increase start moment. After three second, it resume low wind mode, or the operation mode stored in the operating memory. This key set the operate mode when fan is on, if successive pressing of ON/SPEED key, it will operate as low wind, middle wind, strong wind, low wind, middle wind … … .go along with cycle. “ON/OFF” key (extension K) It start fan if pressed when fan is off. It turn on the fan with middle wind for increase start moment. After three second, it resume low wind mode, or the operation mode stored in the operating memory. It turn off the power when fan is on, fan stopped, control circuit resume static state, and stored the operate mode into memory. When the fan turn on next time, it start in the operate mode in the memory (timer and sleep mode will not be stored). “SPEED” key (extension K) SPEED key is used to turn on the fan change speed of the fan. When successive pressing of SPEED key, fan will operate as follows: low wind, middle wind, strong wind, low wind… … go along with cycle. “MODE” key: It used to select the operating mode. If pressed successively when fan is on, it will operate as follows: normally wind, nature wind, sleep wind, normally, nature wind … … go along with cycle. a) Ordinary wind: the he wind speed is set by SPEED key and does not change as time passes. b) Nature wind: it is set in program, and operate with “SPEED” key, can produce strong nature wind, c) Sleep wind: In sleep wind mode, the wind speed steps down automatically one level every interval, until middle nature wind, low nature wind, simulate the really nature wind. it reaches low wind level. Where is the rule of down: 1) If fan set in strong wind mode at first, it operate in strong nature wind for half an hour, then switch into middle nature wind, after half an hour switch into low nature wind, until the preset time end or turn off fan. 2) If fan set in middle wind mode at first, it operates in middle nature wind for half an hour, then switch into low nature wind, until the preset time end or turn off fan. 3) If fan set in low nature wind at first, it operates in low nature wind, until the preset time end or turn off. HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2004.08.03 Page 4 of 9 SC8207 Series “TIMER” key: This key used to set the preset off time. Type mark with “A4”mean have four section time output (0.5, 1, 2, 4hour) accumulated. Type mark with “N3”means have three section time output (1, 2, 4 hour) non-accumulated. When fan is in the time mode, LED will indicate the remain time, means the fan will stop after the display time. “LEVEL SWING” key: If pressed when fan is in the operate mode, it can control the fan swing, it is invalid when fan stopped. “VERTICAL SWING” key: N3: If pressed when fan is in the operate mode, it can control the fan vertical swing, it is invalid when fan stopped. A4: If pressed when fan is in the operate mode, it can control the fan vertical swing. If continue pressed, fan up to down swing. When release the key, swing stopped. “COLD WIND” key: If pressed when fan is in the operate mode, it can control the fan cold-wind switch, it is invalid when fan stopped. “LIGHT” key: It is used to control light, is independent of the operate mode. Buzzer output: a) Turn on send out “Bi-Bi” b) Turn off send out “Bi-“ c) Other available operate (include key press and remote controller receive) send out “Bi” CONTROL PANEL HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2004.08.03 Page 5 of 9 SC8207 Series TYPICAL APPLICATION CIRCUIT Power circuit M M M Controller unit COMPONENTS LIST Symbol FUSE value Symbol 1A, 250V C4 value 0.1µF, R1 2x180Ω/2W C5 R2 200kΩ/0.5W C6, C7 100pF R3 2x47Ω/0.25W D1, D2 1N4007 R4~R9, R16 10KΩ, 0.25W D3 5.1V, 1W R10~R15 470Ω, 0.25W XL 455KHz R17~R19 120Ω, 0.25W BUZ ϕ27 R20, R21 560Ω, 0.25W LED ϕ3x12 C1 1.2µF, 400VAC C2 C3 47µF, 10V D4, D5 1N4148 470µF, 16V KEY 6mmX7 470µF, 10V T1~T6 HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn Z00607MA, MAC97A6 REV:1.0 2004.08.03 Page 6 of 9 SC8207 Series SC5104 transmitter controller unit HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2004.08.03 Page 7 of 9 SC8207 Series PACKAGE OUTLINE 3.00MIN 4.36MAX 7.62TYP 0.25±0.10 UNIT: mm 6.60±0.25 DIP-20-300-2.54 SDIP-22-300-2.54 HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn UNIT: mm REV:1.0 2004.08.03 Page 8 of 9 SC8207 Series HANDLING MOS DEVICES: Electrostatic charges can exist in many things. All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken: • Persons at a work bench should be earthed via a wrist strap. • Equipment cases should be earthed. • All tools used during assembly, including soldering tools and solder baths, must be earthed. • MOS devices should be packed for dispatch in antistatic/conductive containers.
