3. Setup and Installation

The XPS-AT Safety Relay is designed for straightforward integration into existing control circuits. Refer to the wiring diagram provided on the device itself for specific connection points.

Figure 3.1: Front view of the Aoleaby XPS-AT Safety Relay, showing the detailed wiring diagram on the left panel and the time delay adjustment dial on the right panel. Key terminals such as B1, S11, S21, A1/A2, S12, S22, Y1-Y5, and output contacts (13, 23, 33, 14, 24, 34, 41, 57, 67, 42, 58, 68, PE, A2) are clearly labeled. The time dial allows setting delays from 0.5 to 30 seconds.

3.1. Wiring Connections

1. Power Supply (A1/A2): Connect the main power supply to terminals A1 and A2. Ensure the voltage matches the relay's specifications.
2. Inputs (S11, S12, S21, S22, B1): Connect safety devices such as emergency stop buttons, light curtains, or safety gates to the designated input terminals (e.g., S11, S12, S21, S22). The B1 terminal is typically used for reset or monitoring functions.
3. Outputs (13, 14, 23, 24, 33, 34, 41, 42, 57, 58, 67, 68): Connect the controlled load or subsequent safety circuits to the output contacts. The diagram indicates both normally open (NO) and normally closed (NC) contacts.
4. Auxiliary Outputs (Y1-Y5): These terminals provide additional signaling or monitoring capabilities.
5. Protective Earth (PE): Ensure proper grounding by connecting the protective earth to the PE terminal.

3.2. Mounting

Mount the safety relay securely on a DIN rail or suitable panel within an enclosure to protect it from environmental factors and unauthorized access. Ensure adequate ventilation around the device.

4. Operating Instructions

Once properly installed and wired, the XPS-AT Safety Relay operates by continuously monitoring the connected safety circuits. Its primary function is to ensure that machinery or processes are safely shut down or prevented from starting if a hazardous condition is detected.

4.1. Time Delay Adjustment

The right panel of the relay features a rotary dial for adjusting the time delay, labeled "Time [s]". This allows for configurable delays in certain safety functions, typically for controlled stops or delayed activation.

• Use a small flat-head screwdriver to carefully turn the dial to the desired time setting.
• Available settings range from 0.5 seconds to 30 seconds.
• Refer to your system's safety requirements for the appropriate time delay setting.

4.2. Status Indicators

The relay may include LED indicators (e.g., "Fuse", "Input A S12", "Input B S22", "Output Stop") to provide visual feedback on its operational status and the state of connected inputs/outputs. Consult the specific model's documentation for detailed indicator meanings.

4.3. Reset Function

After a safety function has been triggered and the hazardous condition resolved, the relay typically requires a manual or automatic reset to restore normal operation. Refer to the wiring diagram for the specific reset input (e.g., B1 or a dedicated reset button connected to a specific input).

5. Maintenance

The Aoleaby XPS-AT Safety Relay is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended to ensure continued safety and performance.

• Visual Inspection: Regularly inspect the relay and its wiring for any signs of damage, loose connections, or overheating.
• Functionality Test: Periodically test the safety functions connected to the relay (e.g., activate emergency stop, open safety gate) to confirm the relay responds correctly.
• Cleaning: Keep the relay free from dust and debris. Use a soft, dry cloth for cleaning. Do not use solvents or abrasive cleaners.
• Firmware Updates: This device typically does not require firmware updates. If applicable for future models, follow manufacturer guidelines.

Always disconnect power before performing any maintenance or cleaning procedures.
