Nexen ROP 964538 - Manual (Page 4)

INTRODUCTION
The Nexen RSTC Operator Panel (ROP) is a simple compact operator station for making adjustments to the RSTC Tension
Controller. From the ROP, operators can make changes to operation and job settings of the RSTC. The ROP features a
multi-line alphanumeric display that provides: information critical to the job currently in operation, single function push-
buttons, and a rotary knob for tension setpoint adjustment.
The ROP was designed with the machine builder in mind. With its small footprint and shallow depth, the ROP can be
mounted in already crowded control stations. It features one cable that connects directly to the RSTC and thus does
not require additional power supplies or control signals. There are two methods of mounting the ROP, it can be mounted
through a cutout in the control station or using the included bracket it can be mounted vertically on top of a machine
surface.
The ROP was designed with the operator in mind. It is simple to understand and use. All push-buttons are single function,
making it easy for operators to learn their function. An alphanumeric display has only two screens to convey information
without using cryptic codes and the screens switch back and forth automatically without operator intervention. A tension
setpoint adjustment knob located in the center of the ROP makes changes to web tension quick and easy.
The ROP only allows modifications of basic operations/parameters such as automatic/manual mode, output on/off
selections, web tension settings, and taper tension setpoint settings. There are no ROP functions for making changes to
the RSTC’s setup or tuning parameters, which prevents tampering by unauthorized personnel.
A ROP will only work with one RSTC controller equipped with a Modbus RS-485 communications port. Therefore, in
applications where there is more than one RSTC in use, each RSTC will require its own ROP.
