WPC 2000 User Manual 1128500
Introduction 1-5
•
Crank-angle clock–A circular series of LEDs that displays dynamically the approximate
angular position of the crankshaft whether the press is running or idle. Each LED in the
clock represents approximately 11°.
•
Reset/Select Button–Allows you to select indicator segments for display (see previous
item) and clear, or reset, fault conditions that appear on the digital LED display.
•
WPC Settings Key Switch–When turned to “+” (i.e., counterclockwise), increments the
value displayed in the LED readout; when turned to “–” (i.e., clockwise), decrements the
displayed value.
•
Brake Warning LED–An amber LED that flashes when the stopping time of the press
increases to within 10 milliseconds of the preset Stop-time Limit, alerting the operator that
it is time to schedule maintenance on the brake. The LED can be turned off only by
powering down WPC 2000, then powering the unit back up.
•
Interrupted Stroke LED–A red LED that flashes when an Interrupted Stroke (see
Standard Features, below) occurs.
•
Mute Lamp–A lamp that illuminates when the light curtain is muted during the upstroke.
Requires installation of a light curtain and optional light curtain firmware.
Standard Features
WPC 2000 provides the following standard features:
•
Interrupted Stroke–An Interrupted Stroke occurs when the press is Emergency-stopped
before the completion of a stroke by either the operator or an automatic device for
personnel or equipment protection. When this happens, the Interrupted Stroke LED
flashes, and WPC 2000 switches to “Two-hand Maintained Single-stroke” mode. (If WPC
2000 was set to Inch mode, the press stays in Inch mode.) To clear the Interrupted Stroke,
the operator pushes both Run/Inch buttons simultaneously and holds them until the press
reaches the top of the stroke. At this point, the Interrupted Stroke LED turns off, and WPC
2000 automatically reverts to the original operating mode.
•
Customized Status Codes–WPC 2000 provides nine user inputs that allow you to monitor
auxiliary press functions, such as lubrication systems. When one of these functions issues a
Stop command, a unique status code is displayed on the digital LED readout to identify
why the press stopped. Two of the inputs are cross-checked pairs, which you can use for
safety interlocks. If you install the optional Option 1 board, you can connect up to 20
additional non-control-reliable inputs and up to 4 additional control-reliable, cross-checked
input pairs (see Appendix C).
•
Brake Monitor–WPC 2000’s Top-stop brake monitor checks the press’s braking
performance every time a Top-stop command is initiated or when the press completes a
stroke at Top-stop. When the press’s stopping time is within ten milliseconds of the preset
Stop-time Limit, the Brake Warning LED flashes. When the stopping time exceeds the
Stop-time Limit, WPC 2000 issues a Stop command to the press and prevents the press
from being restarted until the brake has been serviced.
•
90° Stop-Time Test–This standard feature is required in order to set the correct safety
distance for personnel-guarding devices including light curtains, two-hand controls, and
type-B movable barriers. The test is performed at 90°, the press’s most critical stopping
