- Page 4 ELECTRONIC PRESSURE SENSOR WORKING DIRECTIONS The electronic pressure sensor, through the use of a microprocessor, controls the pump's speed to obtain the needed flow rate, with the following advantages: - Noise reduction during operation - The optimization of current consumption - A strong reduction of electrical noise, thanks to the slow speed ramp up and ramp down of the motor.
- Page 5 With fast flashing red LED, the pump is being overloaded (due to viscous liquids or gears overheating). While the pump is running, the speed is reduced to keep the current up to the nominal value for 30 seconds, period after which the circuit tries to release again the motor to its normal operating speed.
