Setting the warning thresholds for the warning bit

Setting the warning thresholds for the warning bit 1:

Adjustable warnings

The adjustable warning thresholds can be used to set application-specific limits above which an overvoltage, overcurrent or too low voltage is to be detected at the output and a warning of too high a temperature in the device is to be issued. The warnings can thus be individually adapted to the system.

While the warning bit (0x6000:01) only indicates the warning state, the detailed warning messages can be read in the TwinCAT EventLogger and the Diag History.

Please note that if the absolute, device-specific overvoltage, overcurrent and overtemperature limits are exceeded, the power supply switches to error mode (see 0x6000:02 "Error").

The warning thresholds are set in the CoE Online tab under 0x8000 and 0xF814 "PSU Settings":

Setting the warning thresholds for the warning bit 2:Fig.122: Set values for warning thresholds e.g. 0x8000:14 "Overvoltage warn threshold" using the PS2001-2420-1001 as an example
1. Double-click on the corresponding warning threshold. The "Set Value Dialog" dialog box opens.
2. Enter the corresponding threshold value under "Float" and close the dialog box with "OK"
