Appendix 4-4-1 Self-diagnosis mode 1
Function of self-diagnosis is same as NP1L-RS1/2/4. However, LED name is different.
(1) LED lighting check
Of the external LEDs of the module, the lighting condition of those operated by general purpose communication module
are checked. When the mode selection switch is set to “7,” “TS1,” “TS2,” “CH2 ALM” and “CH1 ALM” LEDs light up in this
order.
Appendix 4-4-2 Self-diagnosis mode 2
(1) RS-485 data check
The general purpose communication modules sends 16 bytes of data once and checks the looped back data received.
When both CH1 and CH2 are normal, “CH1 ALM” lights up; proceeds to step (2).
If CH1 is abnormal, “CH1 ALM” blinks (at 0.5-second intervals) and “ERR” turns ON after 10 seconds; proceeds to step 2.
If CH2 is abnormal, “CH2 ALM” blinks (at 0.5-second intervals) and “ERR” turns ON after 10 seconds; proceeds to step 2.
(2) Preservation of the result of the check
After 10 seconds of displaying the results from (1) above, the module returns to step (1). Here, if the setting of the mode
selection switch has been changed, Self-diagnosis Mode 2 is ended to enter the designated mode.
