1. Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of the SOBOUR ETR4-69-A DIN Rail Multi-Function Timer Relay. This device is designed for industrial and automation applications requiring precise timing control within a voltage range of 24 to 240V AC/DC. It features a Single Pole Double Throw (SPDT) contact configuration and a wide timing range from 0.05 seconds to 100 hours.

2. Safety Information

Please read and understand all safety instructions before installing or operating this device. Failure to comply with these instructions may result in electric shock, fire, or serious injury.

• Electrical Hazard: Installation and maintenance should only be performed by qualified personnel.
• Power Disconnection: Always disconnect power to the circuit before installing, wiring, or servicing the relay.
• Voltage Compatibility: Ensure the supply voltage matches the relay's specified operating voltage range (24-240V AC/DC).
• Proper Wiring: Use appropriate wire gauges and ensure all connections are secure to prevent overheating or short circuits.
• Environmental Conditions: Do not expose the device to excessive moisture, dust, or extreme temperatures outside its specified operating range.

3. Product Overview

The SOBOUR ETR4-69-A is a compact, DIN rail mountable multi-function timer relay. It features intuitive controls for setting time range, specific time, and operating function.

Figure 1: SOBOUR ETR4-69-A DIN Rail Multi-Function Timer Relay. This image shows the front and side view of the timer relay, highlighting the input terminals at the top, the three adjustment dials labeled 'Range', 'Time', and 'Function', and the output terminals at the bottom. The model number 'ETR4-69-A' is visible on the front panel.

Key Components:

• Input Terminals (1-4, 15, B1): For power supply and control signals.
• Output Terminals: For connecting to the controlled load (SPDT contacts).
• "Range" Dial: Selects the overall time range (e.g., seconds, minutes, hours).
• "Time" Dial: Adjusts the specific time value within the selected range.
• "Function" Dial: Selects the desired operating mode (e.g., ON-delay, OFF-delay, Flasher).
• "Rel" Indicator: Status LED for relay output.
• "Power" Indicator: Status LED for power supply.

4. Setup and Installation

4.1 Mounting

The ETR4-69-A is designed for DIN rail mounting. Ensure the DIN rail is securely fastened within an enclosure that provides adequate ventilation and protection from environmental factors.

1. Align the relay's mounting clip with the DIN rail.
2. Press the relay firmly onto the rail until it clicks into place.
3. Verify that the relay is securely attached and does not wobble.

4.2 Wiring

Refer to the wiring diagram provided on the side of the relay or in the product documentation for specific connection details. The relay supports a wide operating voltage range of 24 to 240V AC/DC.

• Power Supply: Connect the appropriate voltage (24-240V AC/DC) to the designated power terminals. Observe polarity for DC connections.
• Control Input: If applicable, connect control signals to the specified input terminals.
• Load Connection: Connect the load to the SPDT output terminals. The SPDT configuration provides one common (COM), one normally open (NO), and one normally closed (NC) contact.
• Terminal Tightening: Ensure all terminal screws are tightened to the recommended torque to prevent loose connections.

5. Operating Instructions

The ETR4-69-A offers multiple timing functions and a broad time range, adjustable via the three front-panel dials.

1. Select Function: Rotate the "Function" dial to choose the desired operating mode (e.g., ON-delay, OFF-delay, interval, flasher). Refer to the product's specific function codes for detailed descriptions.
2. Select Time Range: Rotate the "Range" dial to set the appropriate time scale (e.g., 0.05s-1s, 1s-10s, 1m-10m, 1h-10h, up to 100h).
3. Set Time Value: Rotate the "Time" dial to precisely set the required time duration within the selected range. This dial typically represents a percentage or multiplier of the chosen range.
4. Power On: Apply power to the relay. The "Power" LED should illuminate.
5. Monitor Operation: Observe the "Rel" LED to confirm the relay's output status changes according to the selected function and set time.

Note: Specific function descriptions and their corresponding dial positions are usually printed on the device or provided in supplementary documentation.

6. Maintenance

The SOBOUR ETR4-69-A is designed for reliable, long-term operation with minimal maintenance. However, periodic checks can help ensure optimal performance.

• Cleaning: Keep the relay clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Connection Check: Periodically inspect all wiring connections to ensure they remain tight and free from corrosion.
• Environmental Inspection: Ensure the operating environment remains within the specified temperature and humidity limits.
• Visual Inspection: Check for any signs of physical damage, discoloration, or overheating.

7. Troubleshooting
