Page 9: Overview
Chapter Overview Hardware Features The Guard Locking Proximity (GLP) inputs special-purpose safety relay is designed to use proximity sensors to detect the safe speed of a machine. The GLP safety relay issues lock or unlock commands to a guard locking interlock based on the speed of the signals that are received from the proximity sensors. -
Page 10: Logic Functions
Chapter 1 Overview The optical communication bus is on the sides of the housing. The GLP safety relay operates with the catalog number 440R-ENETR EtherNet/IP™ network interface to transmit its status to the machine control system over an EtherNet/IP network. The GLP safety relay can be operated with other safety relays in the GSR family by use of the single wire safety (SWS) connection. -
Page 11: Logic Setting 3 - Safe Limited Slow Speed, Logic In Off
Overview Chapter 1 outputs and powers the guard locking interlock through 51 and L61 to unlock the gate. TIP If the SWS input turns back ON or if the Reset button is pressed within the Frequency Measuring Time, the GLP safety relay turns the Y32 auxiliary output back ON. -
Page 12: Logic Setting 5
Chapter 1 Overview Logic Setting 5…8 - Guard Locking with Delayed Unlock and Automatic Reset The GLP safety relay uses two timers to delay the turning ON of the safety outputs and unlocking the gate. When the proximity sensor speed falls below SLS1, the GLP safety relay starts the Frequency Measurement timer. -
Page 13: Installation
Chapter Installation This chapter explains the mounting and terminal removal procedures. It also provides information to select the proper enclosure and help prevent overheating. Mounting Dimensions Figure 2 - Dimensions [mm (in.)] 22.5 (0.88) 113.6 (4.47) 119.14 (4.69) DIN Rail Mounting and The GLP safety relay mounts onto 35 mm DIN rail: 35 x 7.5 x 1 mm (EN 50022 - 35 x 7.5). -
Page 14: Removal
Chapter 2 Installation Removal To remove the GLP safety relay, use a screwdriver to pry the DIN rail latch downwards until it is in the unlatched position. Then, swing the module up. Spacing The GLP safety relay can be mounted directly next to other GSR safety relays. When the catalog number 440R-ENETR EtherNet/IP network interface is used, the GSR must be mounted within 10 mm (0.4 in.) of adjacent modules to maintain effective communication. -
Page 15: Preventing Excessive Heat
Installation Chapter 2 This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that are present and appropriately designed to help prevent personal injury as a result of accessibility to live parts. The enclosure must have suitable flame-retardant properties to help prevent or minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. - Page 16 Chapter 2 Installation Notes: Rockwell Automation Publication 440R-UM012E-EN-P - November 2018...

Page 23: Lock Outputs
Power, Ground, and Wire Chapter 3 Lock Outputs Terminals 51 and L61 perform the solenoid lock command. There are various connection possibilities, and the GLP safety relay detects the type of connection during configuration. TLS3-GD2 Connections Figure 14 shows a connection from a GLP safety relay to one TLS3-GD2 guard locking switch. -
Page 24: Multiple Guard Locking Devices And Power To Lock
Chapter 3 Power, Ground, and Wire Multiple Guard Locking Devices and Power to Lock When multiple guard locking devices must be connected to one GLP safety relay, an interposing relay or interposing relays may be required; the connection depends on the lock signal/coil characteristics. The solenoids would be driven by the contacts of the interposing relays. -
Page 25: No Guard Locking
Power, Ground, and Wire Chapter 3 No Guard Locking If no guard locking is required for Stop Cat 1 or SLS functions, then 51 and L61 can be left open. The safety inputs S12 and S22 must be connected to 24V DC. -

Page 31: Status Indicators During Power-Up
Chapter Diagnostic Status Indicators and Troubleshooting The GLP safety relay has five status indicators to provide operating status and diagnostic information. Status Indicators During During power-up, the status indicators turn ON and OFF during their self- check process. The self-check takes about 5 seconds for Status Only Logic and Power-up 10 seconds for all other Logic Settings. -
Page 32: Status Indicators During Diagnostics
Chapter 5 Diagnostic Status Indicators and Troubleshooting Status Indicators During The flashing of the status indicators indicate diagnostics. The PWR/Fault indicator shows the major fault. The IN1 indicator shows more detail. Diagnostics The flashing rate pauses and then repeats itself. IMPORTANT For accurate diagnostics, always start counting after the first pause. -
Page 33: Introduction To Pulse Testing
Chapter Pulse Testing Functions Introduction to Pulse Testing The test pulses are used by the GLP safety relay to detect three short-circuit conditions: • Between the input terminals and +24V • Between the input terminals and 24V common • Between the two input terminals. The outputs have built in redundancy, as shown in Figure 24. -
Page 34: Pulse Testing For Inputs
Chapter 6 Pulse Testing Functions Pulse Testing for Inputs When configuration starts with Logic Switch setting 9 and goes to a setting from 1 to 4, X14 and X24 terminals generate quick pulses that are used to test for short circuit conditions. This configuration is ideal for guard locking interlocks with mechanical contacts. -
Page 35: Webpage
Chapter Ethernet Communication The GLP safety relay is equipped with optical communication via optical link. With the optical link, diagnostic data can be read from the GLP safety relay and transferred to other devices over an EtherNet/IP network. Figure 28 - Arrangement of EtherNet/IP Network Interface and GSR Relays The catalog number 440R-ENETR EtherNet/IP network interface must be in the left-most position. -
