6.C Processor Boards
The 2522 gauge has two main internal boards, the LCD and the processor board. Both boards can be
replaced in the field if either component has failed. The HDI LCD display board can be replaced without
any requirements for calibration; however, if the processor board is replaced, full calibration is required.
For 2522 gauge systems purchased with the optional 4-20 mA output, the user will need to recalibrate
the PLC, slave gauge or any other interfacing components.
The HDI support team can assist in troubleshooting by phone or email to help identify possible issues.
