Instruction Manual

1. Product Overview

The Aramox Normally Open Time Relay Module is a versatile and robust timing control device designed for various applications requiring precise time-based switching. Featuring a large LCD screen for easy monitoring, this module offers multiple operating modes and parameters that can be independently stored. It includes essential safety features such as reverse connection protection.

Key Features:

• Large LCD Screen: Provides clear and easy monitoring of running status, enhancing convenience and saving time.
• Reverse Connection Protection: Equipped with a key stop function (STOPKey) and protection against reverse polarity, ensuring the module is not damaged if connected incorrectly.
• Sleep Mode: Automatically enters sleep mode after 5 minutes of inactivity, turning off the display to conserve power. Can be reactivated with a single key press.
• Wide Measuring Range: Supports timing from 0 to 999 seconds (S), 0 to 999 minutes (min), and 0 to 999 hours (h).
• Durable ABS Material: Constructed from premium ABS material, offering scratch resistance, wear resistance, and overall robustness for a long lifespan.
• Independent Parameter Storage: Allows for independent storage of OP, CL, and LOP parameters.

3. Setup and Wiring

Before connecting the module, ensure the power source matches the module's voltage (DC24V for this model). Always disconnect power before making any connections to prevent electrical shock or damage to the device.

Wiring Diagram:

The module features a terminal block for power input and relay output. Refer to the diagram below for proper connections.

Figure 2: Close-up view of the blue terminal block on the module, showing screw terminals for wiring connections. Typically, these include power input (VCC, GND) and relay output (NO, COM).

1. Power Connection: Connect the DC24V power supply to the designated input terminals (usually marked VCC/+ and GND/-). Ensure correct polarity to utilize the reverse connection protection.
2. Load Connection: Connect the device or circuit you wish to control to the relay output terminals. This module has a normally open (NO) relay output. This means the relay contacts are open (no connection) when the relay is de-energized and close (make connection) when the relay is energized. The output is passive, meaning it does not supply power to the load; it acts as a switch within your circuit.
3. Mounting: Secure the module in a suitable enclosure or panel using its integrated mounting tabs.

Warning: Ensure all connections are secure and insulated to prevent short circuits. Incorrect wiring can damage the module or connected devices.

4. Operating Instructions

The module features an LCD display and four control buttons: UP (▲), DOWN (▼), SET (S), and RESET/RUN (R).

4.1. Parameter Setting Mode:

Press and hold the SET (S) button for 2 seconds to enter the parameter setting mode. The display will show "P-X" (where X is the program number) and then cycle through the parameters: OP, CL, LOP, and time unit selection.

• OP (On-time): The duration for which the relay remains closed (active).
• CL (Off-time): The duration for which the relay remains open (inactive).
• LOP (Loop Count): The number of times the OP-CL cycle will repeat. "---" indicates infinite loop.

Setting Parameters:

1. In parameter setting mode, use the UP (▲) and DOWN (▼) buttons to adjust the value of the currently displayed parameter (OP, CL, or LOP).
2. Press the SET (S) button briefly to move to the next parameter.
3. After setting LOP, the module will display the time unit selection. Use UP (▲) and DOWN (▼) to select:
   • d.d.d: Seconds (0.00 to 99.9 seconds)
   • d.d: Minutes (0.0 to 99.9 minutes)
   • d: Hours (0 to 999 hours)
4. Press and hold SET (S) again for 2 seconds to save the settings and exit parameter mode.

4.2. Operating Modes (P-X):

The module supports various operating modes, typically selected by a short press of the SET (S) button when not in parameter setting mode. The specific modes (P-1 to P-4 or similar) define how OP, CL, and LOP are used.

• P-1: Single Trigger Mode:
  • P-1.1: Trigger ON, then OFF after OP time.
  • P-1.2: Trigger ON, then OFF after OP time, then wait for CL time before next trigger.
  • P-1.3: Trigger ON, then OFF after OP time, then wait for CL time, then repeat LOP times.
• P-2: Cycle Mode:
  • P-2.1: Continuous cycle of OP ON and CL OFF for LOP times.
• P-3: Delay ON/OFF Mode:
  • P-3.1: Power ON, wait CL time, then OP ON.
  • P-3.2: Power ON, wait CL time, then OP ON, then repeat LOP times.

Note: Specific mode behaviors may vary slightly. Refer to the detailed mode descriptions in the full product documentation if available.

4.3. Start/Stop Function:

The RESET/RUN (R) button serves as a start/stop switch. A short press will toggle the module's operation (start/pause/reset the current timing cycle).

4.4. Sleep Mode:

If no button is pressed for 5 minutes, the module will automatically enter sleep mode, turning off the display. Press any button to wake it up.

4.5. Restore Factory Settings:

To restore the module to its factory default settings, press and hold the SET (S) key while powering on the module. This will reset all parameters to their original values.

5. Maintenance

To ensure the longevity and optimal performance of your Aramox Time Relay Module, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the module's exterior. Avoid using abrasive cleaners, solvents, or excessive moisture, which can damage the ABS material or internal components.
• Environment: Operate and store the module in a clean, dry environment, away from direct sunlight, extreme temperatures, high humidity, and corrosive gases.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Avoid Physical Impact: Protect the module from drops or strong impacts, as this can damage the internal circuitry or the LCD screen.
