Table 8. Serial String Format (Continued)

5 - 7 ON-TIME CNT Power-On Time (In Hex) in 10-Minute Increments 00 - 01FFFF

8 - 9 COLD START CNT Cold Start Power-On Count 00 - FFFF

10-11 ICE CNT Ice Events 00 - FFFF

12 - FAIL CNT Total Failures Encountered. This number is incremented each

time the ice detector transitions from OK to fail.

00 - FF

13 - FAIL DTL 1 7 - 4 MSO Frequency Fail Count 0 - F

3 - 0 Heater Fail Count 0 - F

14 - FAIL DTL 2 7 - 4 Not Used Not Used

3 - 0 Not Used Not Used

15 - LAST ERR 1 See ERRSTAT1 Above

16 - LAST ERR 2 See ERRSTAT2 Above

17 - 2ND LAST ERR 1 See ERRSTAT1 Above

18 - 2ND LAST ERR 2 See ERRSTAT2 Above

19 - PERM ERR 1 See ERRSTAT1 Above

20 - PERM ERR 2 See ERRSTAT2 Above

21 - Software Version 7 - 0 Software Version per VDD/SC1 0 - FF

22 - Correlation Count 7-0 0.01" ice accretion increments since power-on 0 - FF

23 - CHECKSUM Summation (1-byte wide) of bytes 0 - 22 0 - FF

10 Electrostatic Discharge (ESD) Consideration

The freezing rain sensor internal components are ESD sensitive, class 1, so proper ESD precautions must be observed

(wrist straps, conductive surfaces) when handling.
