Installing the Position Sensor (Optional)
The position sensor is an optional SmartPAC 2 feature that allows operation of the resolver to
be checked on every stroke. This feature consists of a magnet, which is usually mounted on
the crankshaft, and a magnetic switch, which is usually mounted on a stationary part of the
press past which the magnet passes as the crankshaft turns. The magnetic switch must be
mounted so that it senses the magnetic field at the same point on every stroke.
As the magnet rotates with the crankshaft, the magnetic switch senses the presence of a
magnetic field each time the magnet passes and sends this information to SmartPAC 2. Since
the magnetic switch senses the magnet at the same point on every stroke, SmartPAC 2 can
compare the timing of this signal with the angle of the resolver. If the resolver angle changes

MISALIGNMENT OF RESOLVER AND CRANKSHAFT
If you have installed the position sensor, enable it during initialization and leave it enabled even
though it is optional for SmartPAC 2 operation. If you disable the position sensor to clear an error
message, misalignment between the resolver and crankshaft will go undetected.
Failure to comply with these instructions could result in property damage.
USE CORRECT INSTRUCTIONS WITH SMARTPAC 2/WPC 2000 INTEGRATION
If you are installing the overrun limit switch for the SmartPAC 2 with WPC 2000 integration, you
must follow the instructions in the Setting the Top Stop “On” Angle and Installing the Overrun
Magnet section in Chapter 2 of the SmartPAC 2 with WPC 2000 user manual (Wintriss Part no.
1128600). The overrun limit switch feature is required when WPC 2000 is integrated with
SmartPAC 2. Do not refer to the steps below if you are installing the overrun limit switch.
