SmartPAC 2 with WPC 2000 Integration User Manual
2-24
Installation
•
Light curtain manufacturer
•
Light curtain model number
•
WPC model (i.e., WPC 2000)
•
WPC 2000 firmware version number (located on A or B microprocessor chip label)
•
Wiring diagram from the light curtain manufacturer’s manual
If your WPC 2000 does not have the firmware that allows Foot or One-Hand control and/or
muting of a light curtain on the upstroke, you can connect the light curtain’s dry contact
outputs directly in series with WPC 2000’s E-stop string.
Installing the Resolver
Because the resolver must provide WPC 2000 with the exact position of the crankshaft at
every degree of the stroke (see
, page 1-6), the device must be
driven smoothly at a 1:1 ratio with the crankshaft. Design a method of driving the resolver
directly from the crankshaft, using a chain or timing belt (not a V belt) and sprockets. Use
either an idler sprocket or a spring-loaded resolver base to compensate for slack or stretch.
The drive method you choose must also allow for adjustment of the resolver to its zero
position at top dead center. All sprockets must be keyed or pinned. The resolver shaft has a
standard key. Wintriss stocks a spring-loaded base with a hole pattern to match the resolver.
When designing the drive for the resolver, observe the following precautions:
•
Do not use a chain more than three feet in length
•
Do not use gears, right-angle joints, or shafts with universal joints, which will develop
either too much backlash or too much play
RESOLVER OUT OF SYNCH WITH CRANKSHAFT
Retain the sprockets on the crankshaft and resolver shaft mechanically so they cannot shift or
move out of radial alignment. Be sure that the key on the resolver shaft retains the resolver
sprocket. Use a pin or other method to fix the position of the sprocket on the crankshaft.
Failure to comply with these instructions will result in death or serious injury.
DAMAGE TO RESOLVER
Be sure that the sprocket or gear driving the resolver chain or timing belt is mounted so it is
centered on the crankshaft. If the gear or sprocket is mounted off-center, the resulting loads on
the resolver shaft may cause the unit to fail.
Failure to comply with these instructions could result in property damage.
NOTICE
RAM MUST BE AT TDC BEFORE INSTALLING RESOLVER
The ram must be at top dead center (TDC) before you install the resolver. Use a dial indicator on
the face of the ram if necessary. Set the ram to 0
° ±
2
°
