Abnormal detection distinction at DEMO indicator (LED_red)
It has a case that need to Power OFF immediately after detected an abnormal condition without display any error indication due to safety matter. In such case, a trouble point can be judged by a distinction indication at DEMO indicator which current is being supplied during Power off.
Basically, it is decided to be distinguished which input port of the system microcomputer was detected or which communication information was detected. Moreover, two kinds of over-voltage and drop-voltage are decided to be distinguished, and contents of indication are decided to be changed when it is detected in the range of the A/D value in the A/D input port, for example the over-voltage, the normality voltage, the drop-voltage of the power supply line are being monitored.
DEMO indicator Distinction Display Format
A lighting period (or flashing period) and a lights-off period are controlled as the bottom figure after the abnormal detection and the Power off transition. It will repeat and control 1 frame of the bottom figure. (A lighting period or flash period is mentioned on the "H" side.) 1 frame is set up as 2 sec lighting period in every 3 sec or flashing period, repeat m time, and then the last period only (m+1) should turn off the lights. (To recognize the head position.)
m is 2 m 10, it can be set up in every model freely as long as "‘Distinction No.’ and the Abnormal Detection Table” mentioned in two clauses are protected.
A flashing period is set to one place only of No. 1 - No. m, and others are lighting period. The ‘Error Distinction No.’ is made at which part is flashing. In other words, it is set as the ‘Distinction No.’ by looking at which number is flashing from the head of 1 frame.
Note: It can set up freely in every model the repetition period 3sec, the lighting or flash period 2sec, a flashing periodic 500ms etc. as long as it can be recognized.
