GuardPLC 1800 Controllers Important User Information Solid-state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices.
GuardPLC 1800 Controllers 3 About the Controller The GuardPLC 1800 controller is a programmable electronic system featuring 24 digital inputs, 8 digital outputs, 2 counters, 8 analog inputs, and 4 connections for GuardPLC Ethernet communication.
GuardPLC 1800 Controllers Environment and Enclosure ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11.
GuardPLC 1800 Controllers 5 Mount the Controller IMPORTANT For effective cooling, mount the controller following these guidelines • • • • Mount the controller horizontally. Provide a gap of at least 100 mm (3.94 in.) above and below the controller. Select a location where air flows freely or use an additional fan. Do not mount the controller over a heating device. The controller cannot be panel-mounted. Mount the controller to a DIN rail by following these steps. 1.
GuardPLC 1800 Controllers Wire the Controller The following section describe how to connect the voltage supply and wire the controller’s digital inputs and outputs. Connect the Voltage Supply The 24V DC voltage supply must feature galvanic isolation (in accordance with EN 60950 or UL 1950) since inputs and outputs are not electrically isolated from the processor.
GuardPLC 1800 Controllers 7 Safety-Related Digital Inputs The controller has 24 digital inputs whose status is indicated via status indicators when the controller is in RUN mode. LS+ is a voltage source that provides 24V DC for a group of eight dry contact inputs. There are three groups on the GuardPLC 1800 controller.
GuardPLC 1800 Controllers The safe state of an input is indicated by a 0 signal being passed to the user program logic. If the test routines detect a fault in the digital inputs, a 0 signal is processed in the user program for the defective channel. When a fault occurs, the inputs are switched off (0). Follow the closed-circuit principle for external wiring when connecting sensors. To create a safe state in the event of a fault, the input signals revert to the de-energized state (0).

GuardPLC 1800 Controllers OPC Server The GuardPLC 1800 controller is an OPC client. An OPC server, catalog number 1753-OPC, is available from Rockwell Automation and lets computer applications read and write data to and from the GuardPLC controller. MAC Address The media access control (MAC) address of the controller can be found on the label positioned over both lower RJ45 connections.
GuardPLC 1800 Controllers 17 Reset Push Button The controller is equipped with a reset push button. Reset via the push button is necessary under the following conditions. • You forget the password to go online via the programming software. • You are unable to determine the IP address and SRS of the controller. The push button is accessible through a small round hole at the top of the housing, approximately 4…5 cm (1.6…2.0 in.) from the left rim and recessed approximately 9.5 mm (0.375 in.).
