7.2.9 Power Maintenance Page
The Diagnostics 1 page (see Figure 7-2) consists of readouts that monitor the
unit’s internal environment and the unit’s power measurements for reference.
Any of these items that are outside normal operating limits will post an on-screen
error by way of the systems built-in-test processes.
Figure 7-2: Internal Diagnostics 1
Note: On ST3400 with Mod-A, the following differences should be noted:
• The power supply monitor list is slightly different than shown above;
• Any power supply out-of-tolerance will change from green to red.
• If inverter inputs are floating they will read 1.3V not 0.0V. When
grounded they will read 0.0 V
