Safety Isolation System ElectroGuard Overview Status Communication Capability to a Remote PLC • Optional Remote I/O via Flex modules. Communication can be via the DeviceNet communication platform or the Remote I/O communication platform. Available from 23-1200 Amperes. Specifications Approvals CULUS Standards The ElectroGuard Safety Isolation System is used in place of a disconnect switch for Lockout and Tagout (LOTO). It uses power contactors and Remote Lockout Stations to accomplish LOTO. Isolating the electrical energy usually involves calling an electrician to turn “Off ” the main disconnecting means. The electrician would then perform LOTO of the disconnecting means operating handle. This same procedure is required to perform cleaning, maintenance, setup, lubrication or adjustment. Machines or processes with multiple access points may require operator/maintenance intervention several times a shift (perhaps as often as 60 times per shift). To perform these activities, the operator/maintenance person may be required to place part of his or her body into an area not accessed during normal operation. This may cause serious or fatal injury if LOTO procedures are not followed. The ElectroGuard Safety Isolation System allows the machine operator to safely and quickly accomplish LOTO with dramatically reduced downtime. Provides Energy Isolation • Power isolation accomplished by means of contactors rather than disconnect switches. • Uses redundant, independent and self-monitoring circuits to detect a system fault. • Prevents accumulation of faults in order to maintain the integrity of the safety system. • Tamper-resistant design. Convenient Remote Lockout Station • Allows remote isolation of the electrical power to the machine or process—machine operator simply turns “Off ” a Remote Lockout Station. • A light on the Remote Lockout Station indicates that the threephase power source to the machine or process has been isolated. No Light Means No Entry. • If a fault occurs in the Safety Isolation System, the “System Isolated” light on the Remote Lockout Stations will not illuminate. • Easy Lockout/Tagout. Certified by TUV to meet requirements of Category 4 • Certified by TUV to meet Category 4, the most stringent safety category defined within International Standard EN 954-1/ISO 13849-1. • Subjected by TUV to rigorous third party testing and verification of the Failure Mode & Effect Analysis (FMEA).

X2 GC Voltage Decay Relays (VDR) 2IC To Motor Controllers To Loads After using the normal stopping method of the machine or process, the machine operator turns a Remote Lockout Station handle from the “On” to “Off ” position. The station signals the isolation contactors (1IC and 2IC) to drop out and isolate the supply voltage from the loads (see Control Circuit). When system residual voltage decays to pre-determined levels, the grounding contactor (GC) is energized, connecting the load to ground (see Power Circuit). The grounding contactor (GC) is electrically and mechanically interlocked with the isolation contactors (1IC and 2IC). The “System Isolated” Light will now illuminate on the Remote Lockout Station to indicate the system is isolated. The machine operator then Locks-Out and Tags-Out the station in the “Off ” position.

The wire length from RLS # 8 to the Control Module will be 750ft. 14AWG wire will be used to connect the RLS to the Control Module (see illustration below). 152m (500ft) 304m (1000ft) 259m (850ft) 228m (750ft) Designates field connection points Remote Lockout Station(s) Wire Length Considerations ATTENTION: It is important not to exceed the maximum wire length values shown in this section. If the maximum values are exceeded, this may result in an unreliable signal to the Safety Isolation System. Consider using an Expansion Module if wire lengths greater than those shown for the Remote Lockout Stations are needed. Each Remote Lockout Station is connected to the Control Module in the Power Panel of the Safety Isolation System. The total length of the wire used to connect the Remote Lockout Stations to the Control Module should not exceed the maximum values shown in the following tables. Calculate the total wire length as follows: 1. Determine the distance in feet or meters from each Remote Lockout Station to the Control Module (located inside the Safety Isolation System Power Panel). 2. Sum the distances for all of the Remote Lockout Stations. 3. Double this value. 4. Compare this doubled value with the maximum values for total wire length shown in the table below: Total Wire Length for Remote Lockout Stations For North America Wire Gauge 14AWG 16AWG 18AWG Max.

Since this installation will require eight (8) RLS, an optional 4 port Expansion Module will also be used. The Expansion Module will be wired to the Control Module and will take the place of one of the original six RLS. We will, therefore, plan to wire five (5) of the RLS directly to the Control Module and three (3) of the RLS to the Expansion Module. Since the Expansion Module allows greater wire lengths than the Control Module, we will plan to wire the RLS to be installed furthest away from the Power Panel to the Expansion Module. For RLS # 1: wire length = 50ft x 2 = 100ft For RLS # 2: wire length = 200ft x 2 = 400ft For RLS # 3: wire length = 100ft x 2 = 200ft For RLS # 4: wire length = 300ft x 2 = 600ft For RLS # 5: wire length = 500ft x 2 = 1000ft If the application requires a total wire length greater than those shown in the table, one or more Expansion Modules should be used. The maximum wire length for the Expansion Modules is shown in the following table: 12-18 Safety Isolation System ElectroGuard Wire Length Considerations/Ordering Instructions The total wire length for the 5 RLS to be wired to the Control Module will be: 100ft + 400ft + 200ft + 600ft + 1,000ft = 2,300ft Per the table entitled Total Wire Length for Remote Lockout Stations on page 12-18, the maximum allowable wire length for 14AWG wire is 4,600ft for the RLS to be wired to the Control Module. This portion of the installation will be within the maximum wire length permitted. Next, we need to check the wire length calculation for the RLS to be wired to the Expansion Module. For RLS # 6: wire length = 1000ft x 2 = 200ft For RLS # 7: wire length = 850ft x 2 = 1700ft For RLS # 8: wire length = 750ft x 2 = 1500ft The total wire length for the 3 RLS to be wired to the Expansion Module will be: 2000ft + 1700ft + 1500ft = 5,200ft Per the table entitled Total Wire Length for Expansion Modules on page 12-18, the maximum allowable wire length for 14AWG wire is 40,000ft for the RLS to be wired to the Expansion Module. This portion of the installation will also be within the maximum wire length permitted. b. Sum the full-load currents of all the motor loads to be connected to the Safety Isolation System. To this value add the current values of all resistive loads to be connected to the Safety Isolation System. This value is the “combined load full-load current.” c. Find the horsepower or kilowatt rating of a single motor with a full-load current value greater than or equal to the “combined load full-load current” value determined in Step “b”. d. Select the Safety Isolation System that meets or exceeds this horsepower or kilowatt rating at the required voltage and frequency. e. Sum the locked-rotor currents of all the motor loads to be connected to the Safety Isolation System. To this value add the current values of all resistive loads to be connected to the Safety Isolation System. This value is the “combined load locked-rotor current”. f. Find the horsepower or kilowatt rating of a single motor with a locked-rotor current value greater than or equal to the “combined load locked-rotor current” value determined in Step “e”. g. Select the Safety Isolation System that meets or exceeds this horsepower or kilowatt rating at the required voltage and frequency. h. Compare the ratings of the Safety Isolation Systems selected in Steps “d” and “g”. Select the larger of the two systems for your application. Determine how many Remote Lockout Stations are required for the application. Determine how many Expansion Modules (if any) are required for the application. Pick suitable enclosure type(s) for the Safety Isolation System Power Panel, Remote Lockout Stations and enclosed modules (e.g., Expansion Modules, Pneumatic Isolation Module). Determine what, if any, factory installed options are required for the application (e.g. Pneumatic Isolation, Status Communication to remote PLC, metering). Ordering Instructions 1. Determine the Catalogue Number of the Safety Isolation System based on the rating of the load(s) to which it will be connected as follows: If the Safety Isolation System is connected to a single motor load, the horsepower or kilowatt rating of the system should be determined as follows: a. Select the Safety Isolation System that meets or exceeds the horsepower or kilowatt rating of the load at the required voltage and frequency. If the Safety Isolation System is connected to two or more motors or one or more motors in combination with other loads, the horsepower or kilowatt rating of the system should be determined as follows: a. Identify the types of loads (i.e. motor, resistive) and the values of the currents of each of the loads (i.e. steady-state current for resistive loads, full-load and locked-rotor currents for motor loads) to be connected to the Safety Isolation System. 2. 3. 4. 5. 12-19
