With the help of the external circuit, the AC 50/60Hz clock signal can be extracted to be used as timer clock source. ● DISC Timer chain Button sampling circuit ● Button is tied to RELAY pin, once ON, once OFF. Pressing button ON/OFF to turn on/off relay and start/reset internal timer. RELAY is active when the button is pressed at first time. DISC is active when the button is pressed at second time. DISC outputs Low when relay is ON. For PT8A2526/2536 two buttons (ON, OFF) Button tied to DISC pin is for ON, Button tied to RELAY pin is for OFF. Pressing button ON to turn on relay and start internal timer. Pressing button OFF to turn off relay and reset internal timer. RELAY is active when button ON is pressed. DISC is active when button OFF is pressed. DISC will output a narrow pulse each 8ms when relay is ON. Buzzer For PT8A2524/25/34/35/44/45, a buzzer will make 0.5s sound with a frequency of 4KHz every 1s for 6 times after internal timer times out. Pin DISC will output 4KHz with 25% duty for 0.5s to let the buzzer work, then output 32KHz with 25% duty for 0.5s, after the output 6 times 4KHz, DISC will keep output 32KHz. RELAY driving circuit RELAY driving signal is special, anytime, first 8ms is always high following output pulse signal with about 32KHZ and 25% duty cycle. DISC is used to limit the voltage of external high voltage capacitor by discharging it with a NPN transistor. After power on, DISC should be active during first 1s before RELAY in order to charge the external high voltage capacitor. RELAY is active to output first 8ms high following 32KHz with 25% duty cycle. When relay is OFF, RELAY will output a narrow pulse each 8ms, while, DISC is active to output 32KHz with 25% duty cycle. 8ms For PT8A2525/2535 one button (ON/OFF) Button sampling circuit senses button’s operation 3 times per 8ms. System will sample the button’s operation during first 100ms after power on, if buttons are pressed during this period, then system will start 3s timer to check if the chip will enter into quick test mode (see test mode section). If the related button is pressed over 3s just after power on, chip will enter quick test mode as soon as the button is released. If buttons are not pressed during first 100ms, system will operate normally. 8ms Driving signals of RELAY and DISC With external buttons, ON/OFF/RESET function can be realized. User can select one button with once ON, once OFF or two buttons to turn ON or OFF separately, also use one button to restart timer. ● 8ms RELAY is active Internal RC oscillator circuit Timer chain can be used to generate various timer including 15/30/45/60/90/120/240/480min. ● 8ms RELAY It is employed to create pulse driving signal for RELAY, it is a completely internal RC oscillator with frequency of about 128KHZ. ● 8ms 32KHz with 25% duty ● Quick Test Mode(QTM) In order to make the manufacturer’s test convenient, quick test mode is designed to speed up the test. QTM can be accessed by pressing button (ON or RESET) over 3s (option 2s) once power on. It can exit automatically after quick test timer is expired, system needs to power on again to come back normal operation after quick test mode. Any button operations will be ignored in QTM. For PT8A2524/2534 one button (RESET) Button is tied to RELAY pin. Pressing button RESET to turn on relay and restart internal timer. RELAY is active once the button is released. DISC will output low when relay is ON. Note: For PT8A2526/2536, the button to be pressed over 3s to enter into QTM is OFF.
