Pressing the servo center icon will initiate the servo centering operation for web guiding applications. This
operation can be performed only when the SCU5 controller is in manual mode. Pressing this momentary
switch will initiate the servo centering operation which would toggle the icon to green. When the controller
is in servo centering mode, the actuator connected to the SCU5 controller will move towards the home
position or center position which is provided by the servo center sensor, typically an inductive proximity
switch. As soon as the actuator reaches the home or the center position, the actuator will stop and the state
of the momentary switch will change from Servo-centering (Green) to Default/normal state (Red).
The servo center feature allows the guide to be centered quickly to facilitate threading of the web during
changeover.
WARNING:
Servo centering operation results in a change in the web guide position causing process upset.
Caution must be exercised when performing this function and should be done by those who completely
understand the consequence of this change.
WARNING:
Servo centering can be performed only when the web guiding system is in manual mode.
Pressing the servo center icon during automatic operation will perform a different function.
WARNING:
This is an automatic procedure of the web guiding system. No personnel should be performing
manual work on or around the guide during the servo-centering procedure. Failure to follow this warning
could result in crushing of body parts at pinch points around and within the web guiding system.
NOTE:
This functionality has no meaning for sensing application. However, some custom applications with
custom firmware may use the functionality.
Jog-left/Jog-right Icon
Jog-left OFF
Jog-right OFF
Jog-left ON
Jog-right ON
The Jog-left/Jog-right icons allow the operator to manually move an actuator connected to the SCU5
controller in either direction. These operations can be performed only when the controller is in manual
mode. Both these icons act as a momentary switch that will turn ON (Green) when pressed and turn OFF
(Red) when released.
The Jog operation will continue as long as the button is pressed and will stop as soon as the button is
released. This operation can only be performed when the guide is in manual setting.
