Rockwell Automation Allen-Bradley Guardmaster 440G-LZS21SP Series Operation & User’s Manual

Chapter 7 Application Examples Figure 16 - CR30 Configuration in CCW Wiring to 1734 Guard Point I/O The 440G-LZ safety switch can be connected to a 1734 Guard Point I/O. The cordset (catalog number 889D-F8NB) has 24 AWG wires, which allows three wires to be connected to one terminal. Figure 17 on page 44 shows a wiring example of a Power-to-Lock switch with a Door Status auxiliary signal. The PLC logic checks to see if the door is closed before issuing a lock command. The schematic for this example is shown in Figure 22 on page 47 ...

Chapter 7 Application Examples Figure 23 - Studio 5000® Example Logic Program Wiring to 1732 ArmorBlock Guard I/O The 440G-LZ can be connected to a 1732ES or 1732DS ArmorBlock by using an 871A-TS5-DM1 field attachable connector. The cordset 889D-F8NB has 24 AWG wires; which allows three wires connected to one pin. An example schematic is shown in Figure 24 on page 49. ...

15 Installation Chapter 3 Verify that two fasteners are used with at least one fastener that is fitted close to the actuator bracket bend. The following drawings show mounting possibilities when attaching to extruded aluminum profile and flat surface guard doors. IMPORTANT The performance of the switch can only be guaranteed if the provided actuator mounting bracket is used. Mounting the actuator without the supplied bracket can result in the reduction of performance. ...

Chapter 7 Application Examples Figure 14 - DG with 440G-LZ Safety Switch Schematic Wiring to CR30 Relay The CR30 is a software configurable relay that can easily interface with the 440G-LZ guard locking safety switch. Version 10 and later of Connected Components Workbench™ has a locking function that is useful for guard locking applications. Figure 15 on page 43 shows an example schematic. The CR30 monitors the motor running signal from the PowerFlex® 525. When the motor is not running, the safety gate can be unlocked, and the ...

7 Chapter 1 General Description Guardmaster 440G-LZ Safety Switch Overview This Guardmaster® 440G-LZ guard lock safety switch functions by extending a locking bolt from the switch through a hole in the actuator, which prohibits the opening of a guard. The locking bolt drive mechanism and logic confirm that the locking bolt is allowed to extend only when the corresponding actuator is detected within range. RFID technology enables high precision operation while meeting the requirements to prohibit actuator substitution as described in ...

Chapter 7 Application Examples Figure 19 - 1734-IB8S Module Properties – Input Configuration Figure 20 on page 46 shows the Test Output tab of the 1734-IB8S Module Properties. In this example, Points 0 and 1 are set to Pulse Test as these points help check the integrity of the contactors K1 and K2, to be sure they are off before the logic program energizes the contactors. Points 2 and 3 are set to Standard. Point 2 is the LOCK command. Point 3 applies power to the safety switch, as well as, supplies power to the OSSD inputs. By ...
