NET Web Guide Control System

Installation
The MICRO 4000 NET system has been tested, calibrated, and run at the factory in a
closed-loop configuration. After installation, most systems may be started up and operated
without further adjustment. Refer to the connection and wiring diagrams on page 139 for cable
installation information.
OEMs: If shipping clamps and spreaders are removed, make sure that they are re-installed
prior to forwarding to the final destination. Verify that all mechanical and electronic
components are secured for shipment.
1. Linear Actuator and Guide
Install the web guide and linear actuator into the machine. Refer to the guide and actuator
application drawings on page 139 for installation information. Once the web guide is installed,
it must be trammed to the rest of the machine.
Note: Make sure the actuator is in the servo-center position before tramming the web guide.
This may not be possible until after step 5, below.
Important: Special attention must be given to the actuator mounting. Any mechanical
compliance or backlash in the actuator mounting will seriously affect guiding accuracy.
Deflections of a few thousandths of an inch will reduce the performance of the system. Also,
an anti-rotation bracket is required for most applications. The actuator must be allowed to
gimbal slightly on the ball rod ends to accommodate minor actuator mounting misalignment.
Note: Motor contains no temperature-sensing device to protect motor from excessive
temperature due to failure-to-start or overload. Motor should be protected by other means in
accordance with the NEC and local code requirements.
2. Sensor (Edge Detector or Digital Line Guide)
Install the sensor (edge detector or digital line guide). Refer to the guide and sensor
application drawings on page 139 for installation information. Use of the AccuWeb edge
detector mounting bracket simplifies installation and adjustment.
The sensor cable should be long enough so that the sensor may be repositioned if the web
width or web path changes. The standard cable length is 12 feet. Longer cables are available
upon request.
Note: The cables supplied with the system have been chosen for specific shielding and
capacitance properties. DO NOT splice or replace these cables with any other style or
configuration of cable. This can cause serious degradation or complete loss of system
performance. DO NOT SPLICE CABLES. Longer cables are available upon request.
3. Control Enclosure
Install the control enclosure on a rigid mount such as a wall or secure framework. Do not
install the control enclosure on the side of a dryer or in other high temperature areas. Also, do
not install the control enclosure on a moving winder structure.
