4.1. ERRORS SIGNALIZATION
When works ADA-401WP module, may signal a short sound for different types of errors like:
- errors of sensors searching,
- errors of reading temperature from sensors,
- errors in RS485 communication,
- errors of CRC sensors serial number,
- short circuit on 1-WIRE network,
- no sensor,
- no 1-WIRE network controller.
The reasons of those errors can be found in ADAUtil software, checking:
- RS485 interface Diagnosis,
- 1-WIRE interface Diagnostic,
- System Diagnostic,
- Measurement channels Diagnostic
5. CONFIGURATION
Configuration of ADA-401WP module should be made by the use of
ADAUtil software
– delivered whit the module.
To make configuration, connect ADA-401WP to a PC (according to point
CONNECTION TO COMPUTER)
and be the power. If after
power, on the front panel is not lit green LED PWR, check the power connection (polarity).
Once powered correctly, the module must be set to configuration mode by the use of the switch SW1, as shown in the table below.
