4.4.6 Directions for Detecting the Correct Error Code
1. Take the error code displayed at the matrix location VH 90 and divide it by 16. The digit(s) before the decimal
point represent the error code associated with the temperature channel.
Table 17:
Temperature Error
Bit: 0010
xxxx
Temperature <-15°C
Temperature >+40°C
Output on CH.2 less than 4 mA
Output on CH.2 greater than 20 mA
2. To calculate the moisture error code, take the remainder of the previous division (the digit(s) after the decimal
point) and multiply it by 16.
Table 18:
Moisture Error
Bit: 0111
xxxx
RH <0%
RH >100%
Output on CH.1 less than 4 mA
Output on CH.1 greater than 20 mA
3. Use Table 4-3 on the next page to convert both numbers into their respective bit codes.
Note: Every “1” corresponds to an error. See the example below Table 4-3 for help when calculating. Please refer to
“Troubleshooting” on page 27, for further information.
