This component is designed for use in industrial control applications, providing a reliable electrical contact for pushbutton operators. Please read this manual thoroughly before proceeding with any procedures.

2. Safety Information

Always adhere to the following safety guidelines to prevent personal injury or damage to equipment:

• Disconnect Power: Ensure all power to the equipment is disconnected and locked out before installation, wiring, or maintenance.
• Qualified Personnel: Installation and servicing should only be performed by qualified electrical personnel familiar with local electrical codes and safety practices.
• Proper Wiring: Use appropriate wire gauges and insulation for the specified voltage and current ratings. Ensure all connections are secure.
• Environmental Conditions: Do not expose the contact block to conditions outside its specified operating environment (e.g., excessive moisture, extreme temperatures, corrosive atmospheres).
• Intended Use: Use this product only for its intended purpose as an electrical contact block for compatible pushbutton operators.

3. Product Overview

The Allen Bradley 800E-2X01 is a 22.5mm latch mount contact block, designed to provide a Normally Closed (NC) contact function within an industrial control circuit. It features screw terminals for secure wiring connections and is compatible with various Allen Bradley 22.5mm pushbutton operators.

5. Installation and Setup

Follow these steps for proper installation of the contact block:

1. Power Disconnection: Ensure all power to the control panel or machine is completely disconnected and verified de-energized.
2. Mounting: The 800E-2X01 contact block is designed for latch mounting onto a compatible Allen Bradley 22.5mm pushbutton operator. Align the contact block with the mounting mechanism on the pushbutton operator and secure it firmly until it latches into place.
3. Wiring: Connect the control circuit wires to the screw terminals on the contact block. Refer to the electrical schematic of your system. Ensure that the wire insulation is stripped to the correct length and that the wires are securely fastened under the screw terminals to prevent loose connections. Observe the voltage and current ratings specified on the contact block (refer to Figure 3).
4. Verification: After wiring, double-check all connections for tightness and correct routing. Ensure no bare wires are exposed that could cause a short circuit.
5. Power Restoration: Once installation is complete and verified, restore power to the system.

6. Operation

The 800E-2X01 is a Normally Closed (NC) contact block. In its unactuated state (when the associated pushbutton is not pressed), the electrical circuit through the contact block is closed, allowing current to flow. When the pushbutton operator is pressed, the plunger on the contact block is depressed, causing the internal contacts to open, thereby breaking the electrical circuit. Releasing the pushbutton returns the contact block to its normally closed state.

7. Maintenance

The Allen Bradley 800E-2X01 contact block is designed for long-term reliability with minimal maintenance. However, periodic inspection is recommended:

• Visual Inspection: Periodically inspect the contact block for any signs of physical damage, discoloration, or excessive wear.
• Connection Check: Ensure all screw terminals remain tight and that wiring connections are secure. Loose connections can lead to overheating or intermittent operation.
• Cleaning: If necessary, gently clean the exterior of the contact block with a dry, lint-free cloth. Avoid using solvents or abrasive cleaners.

8. Troubleshooting

Troubleshooting for a contact block is generally straightforward:

• No Circuit Change: If the circuit does not open when the pushbutton is pressed, or does not close when released, first check the mechanical connection between the pushbutton operator and the contact block. Ensure the plunger is being fully actuated.
• Intermittent Operation: Check for loose wiring connections at the screw terminals.
• Continuity Test: With power disconnected, use a multimeter to test the continuity of the contact block. In its unactuated state, an NC contact should show continuity (low resistance). When actuated, it should show open circuit (high resistance).
• Replacement: If the contact block fails continuity tests or shows significant physical damage, it should be replaced with an identical Allen Bradley 800E-2X01 unit.

9. Warranty and Support

For warranty information, technical support, or to obtain replacement parts, please contact your authorized Allen Bradley distributor or visit the official Rockwell Automation website. Ensure you have the model number (800E-2X01) available when seeking support.
