LXC706 small generator controller design which protection fu
LXC706 Generator controller LIXISE independent research and development of new products, is currently on the market the most small size of the controller,Suitable for small generator sets, especially for small gasoline intelligent control of the unit.And there are manyperformanceCharacteristics of high reliability, the product once listed, loved by customers at home and abroad.On the performance and characteristics we just have to introduce a lot of detailed to introduce the below we are doing it on the protection design.
LXC706 small generator controller main design the following protection functions:
1, low oil pressure: security after the delay starting test for 5 seconds after the alarm stop.
2, high temperature: security after the delay starting test for 10 seconds after the alarm stop.
3, low fuel level warning: when the fuel level for lower than the preset value of 10 seconds, a low fuel level signals, this value is only warning non-stop.
4, speeding: starting test when the phone is switched on for overspeed alarm stop after 2 seconds.
5, less speed: after the idle time delay starting test for 15 seconds after a low speed outage warning signals.
6, the starting failure: at the end of the default starting times, starting is not successful, alarm downtime.
7, stop failure: at the end of the outage time delay, if not stopped the outage failure warnings, not latch.
8, and high battery voltage: when the battery voltage over the preset value for 20 seconds, a high voltage battery warning signals, non-stop.
9, low battery voltage: continue when the battery voltage is lower than the preset value for 20 seconds, a low battery voltage warning signals, non-stop.
10, emergency stop: when the emergency stop input is valid, to immediately stop the output, at the same time cut off fuel, preheating and starting signal, signal emergency stop alarm.
11, the generator voltage is too high: when the continuous sampling voltage higher than the preset value, at the end of the abnormal delay, signal generator voltage is too high, outage alarm at the same time.
12, the generator voltage is too low: when the sample voltage is lower than the preset value continuously, at the end of the abnormal delay signal generator voltage is too low, outage alarm at the same time.
13, power frequency is too high: when the sampling frequency for 10 seconds, the signal generator frequency is too high, outage alarm at the same time.
14, power frequency is too low: when the sampling frequency for 2 seconds after the signal generator frequency is too low, outage alarm at the same time.
15 and public alarm: when a speeding, less speed, high temperature, low oil pressure, emergency stop, start failure, stop failure alarm, battery voltage is too high, the battery voltage is too low, public warning lights flashing, public alarm output.
