4. Electrical Power
Note: Electrical power must be provided from a customer-supplied disconnect. Connections
must comply with NEC 590 and other local codes.
a) Verify that the power source is off and locked out.
b) Install the electrical power cord through the right-most cord grip.
c) Connect the cable to the terminal block located inside the enclosure.
d) Make sure the circuit board is free of metallic debris such as screws, lockwashers, and
wire strands.
e) If any of the cables have been removed, shortened, or modified in any way, make sure
the connections agree with the appropriate connection and wiring diagrams located on
page 139.
5. Static Test
a) Apply power to the system.
b) Press the MANUAL button.
c) Press the IN and OUT buttons several times. The actuator and web guide mechanism
should move freely and without hesitation.
d) Press and hold the IN button. When the guide mechanism gets near the In limit, release
the button.
e) Jog the IN button repeatedly until the actuator automatically stops at its end-of-travel
limit.
Caution: If the actuator or web guide mechanism hits a mechanical obstruction before
the actuator stops automatically at its end-of-travel limit, release the button immediately.
Continued activation will cause serious damage to the actuator motor and/or guide
mechanism.
f) Repeat the previous two steps using the OUT button in order to check the Out limit.
g) Press the SERVO-CENTER button and verify that the actuator drives to the center of its
stroke.
6. Dynamic Test
a) Press the SERVO-CENTER button and verify that the actuator drives to the center of its
stroke. This also places the web guide in its center (or tram) position.
b) Thread the web through the machine and put a slight tension on it so that the web is in its
normal operating position.
