5-2 Troubleshooting
Responding to WPC 2000 Faults
Whenever WPC 2000 detects a problem with the clutch/brake control, the press, or peripheral
equipment, it sends a Stop command to the press and generates a fault on the WPC 2000
display. Most of these faults are shown as a three-character alphanumeric code in the digital
LED readout (see Figure 5-1). The initial letter, E, F, or H, indicates how to clear the fault
after it has been corrected and, in the case of F and H faults, specifies the processor (WPC
2000 has two processors) that reported the problem, as shown in Table 5-1.
The two-digit number following the initial letter identifies the specific WPC 2000 fault. For
example, fault code F11, which is shown in Figure 5-1, indicates that the ram moved when the
DSV was de-energized. All E, F, and H faults are documented in numerical order starting on
page 5-5.
To respond to a fault, do the following:
1. Correct the problem that caused the fault.
