The NX-REG controller has all the required I/Os to interface efficiently on any printing or converting machine. Fast switching optical or magnetic sensors are used to track the relative position between a print or a tool cylinder and register marks printed on the material. A time based output activates the correction motor on the unit to keep the register position precisely at its set point. The controller accepts push-button and switches signals from machine console and can be operated either from the console's buttons, from its communication port or from both at the same time.
The dual switched output controls advance or retard motion on a unit by utilising the proper type of output solid state relays. The relays directly activate the correction motor installed on the unit's gearbox or compensator or sends a time based signal to a servo or a stepper drive. For most retrofit applications the relays simply connect in parallel with the existing advance and retard controls of the unit.
Minimal installation requires only
one push-button and one switch to
operate the controllerStandard industrial sensors are
used to track the register positionExternal solid state relays of the proper
type activate the correction motor
The controller comes with documentation on CD-ROM which also includes the NX-SGUI service interface program for Windows(TM). This program allows to connect a laptop to a single controller or to a network of controllers, it is used to configure controllers in the field, to test and operate a control system.

NETWORKABLE
The flexibility of the NX-REG controller allows to size projects from a single unit application operated by one push-button and one switch only to a multi-units distributed control system with RS-485 networking and graphical operator interface. The communication and commands protocol is also included in the documentation allowing to develop a custom interface on a host control system.
A DISTRIBUTED CONTROL SOLUTION FOR AUTOMATIC REGISTER APPLICATIONS
OPERATOR INTERFACES
Two models of operator interfaces are available: the NX-OP72 is a small footprint device with LCD screen and keypad for single unit applications and the NX-DGUI is a graphical operator interface with touch screen which can control up to 16 networked units.
