2-22 Installation
1. Mount the resolver by bolting it to the press or other platform at the desired location.
2. Make sure the press is at TDC.
3. Rotate the resolver shaft so that the keyway is aligned with the arrow on the housing (see
Figure 2-11).
4. Keeping the keyway aligned with the arrow, attach the chain or drive mechanism.
Wiring the Resolver
To wire the resolver, perform the following steps:
1. If the resolver cable is not already connected to the resolver, locate the cable, plug the
molded connector into the resolver (it only goes one way), and twist the locknut so the
connection is tight.
2. Run the resolver cable through conduit from the resolver to one of the knockouts in the
bottom of the WPC 2000 enclosure.
3. Find the resolver terminal block, TB 106, on the WPC 2000 Main Processor board (see
Figure 2-12, page 2-23 or Figure 2-13, page 2-24), and remove the L-shaped connector.
4. Viewing the resolver from the shaft end, determine whether the shaft will turn clockwise
or counterclockwise when the press runs.
5. Measure and cut the resolver wires so they reach TB 106, then wire them to the L-shaped
connector, referring to Table 2-21, page 2-63, and Figure 2 at the end of the manual. Make
sure you connect the black and yellow wires correctly, based on the direction in which
your resolver will rotate–clockwise or counterclockwise. Refer to Connecting Wires to
Terminal Block Connectors, page 2-5 if you need help wiring the TB 106 connector.
6. Double-check connections when you are finished wiring.
7. Plug the L-shaped connector firmly into its base. It can plug in only one way.
It does not matter which direction the resolver turns when the press runs. You adjust for the
direction of rotation when you wire the unit (see Wiring the Resolver, next section).
You can run the resolver and overrun limit switch cables through the same conduit (see
Figure 2-1, page 2-4 for an example). If you do so, make sure not to cut the cable and
wires until both the resolver and the overrun limit switch are installed.
CONNECTOR WIRING
Before wiring, place the connector over its base the way it will plug in (it can plug in only
one way) and double-check pin assignments to make sure you wire correctly.
