Observe the following precautions when troubleshooting the unit:
• Stop the unit using either the Stop input or Function Loss input.
• Disconnect, tag, and lockout AC power before working on the unit.
• Verify that there is no voltage present at AC input terminals R/L1, S/L2, and T/L3.
Refer to Figure 5.2 for the location of the terminals.
• Wait five minutes and verify that the DC bus has discharged to zero volts. See
Figure 5.2 for the location of the DC bus test points.
11.1 Fault Codes and Corrective Actions
The following table describes normal operational faults that may be corrected by the
user. For standard units, the corrective action assumes that a Reset pushbutton is wired
between control terminals 15 and 13, as described in Section 7.8.
If a fault occurs, do the following:
1. Try to clear the fault first by pressing the Reset pushbutton (or key on local
operator control units). If the fault reoccurs, continue with Step 2.
2. Refer to Table 11.1 to identify the fault code and the possible causes.
3. Perform the corrective action(s).
4. Clear the fault by pressing the Reset pushbutton (or key).
