We have a JZ20-R31 that displays the following message on power up: WDT ERR @ 22. The 24VDC power supply for the Jazz died recently and was just replaced. On powering up the PLC the screen was blank for a few minutes and then the WDT ERR message is displayed on the screen.
Can any suggest what this indicates and how to remedy?
