2. Safety Information

Please read and understand all instructions before operating the FRM01 module. Failure to follow these instructions may result in electric shock, fire, or damage to the product or connected equipment.

• Electrical Safety: Ensure all power connections are made correctly and securely. Disconnect power before making or changing any wiring connections.
• Voltage and Current Ratings: Do not exceed the specified voltage (DC 12V service voltage, AC 0-250V / DC 0-30V max. 10A control voltage) and current ratings for the module and its relay contacts.
• Installation Environment: Install the module in a dry, clean environment, away from moisture, dust, and extreme temperatures.
• Professional Installation: If you are unfamiliar with electrical wiring, seek assistance from a qualified electrician.
• Component Handling: Handle the module with care to avoid damaging sensitive electronic components.

4. Setup and Wiring

Proper wiring is essential for the correct and safe operation of the FRM01 module. Refer to the diagrams below for connection details.

4.1 Power Supply Connection

Connect the DC 12V service voltage to the module's power input terminals. Ensure correct polarity (DC+ and DC-).

4.2 Load Connection

The module features a single-pole double-throw (SPDT) relay with Normally Open (NO), Normally Closed (NC), and Common (COM) contacts. Connect your load (e.g., light, motor) to these terminals based on your application's requirements:

• Normally Open (NO): The circuit is open (disconnected) when the relay is de-energized and closes (connects) when the relay is energized.
• Normally Closed (NC): The circuit is closed (connected) when the relay is de-energized and opens (disconnects) when the relay is energized.
• Common (COM): This is the shared terminal for both NO and NC contacts.

4.3 Input Signal Connection (CH1)

The CH1 interface accepts a high-level pulse signal (DC 3V-30V) to trigger or reset various functions depending on the selected operating mode.

5. Operating Modes

The FRM01 module supports several operating modes, each with distinct timing and triggering behaviors. The specific mode is selected during programming.

5.1 Timing Pick/Off Mode

In this mode, after the module is powered on, the relay will energize (pull) for a set duration T1. After T1 expires, the relay de-energizes. A high-level pulse on the CH1 interface will restart this function.

5.2 Timing Pull Off Again Mode

Upon power-up, the relay remains de-energized. After a delay of T1, the relay energizes. It then remains energized for a duration of T2 before de-energizing again. A high-level pulse on the CH1 interface will restart this sequence.

5.3 Infinite Loop Timing Mode 1/2

After power-up, the relay remains de-energized. After a delay of T1, the relay energizes. It then remains energized for a duration of T2 before de-energizing. This cycle (T1 delay, T2 energized) repeats indefinitely. A high-level pulse on the CH1 interface can restart the entire loop.

5.4 Latching/Relay Modes

A high-level pulse on the CH1 interface will energize the relay. A subsequent high-level pulse on CH1 will de-energize the relay. This mode acts as a toggle switch.

5.5 Pull/The Timing Mode

When the module is powered, the relay remains de-energized. A high-level pulse on the CH1 interface will energize the relay for a duration of T1. After T1 expires, the relay de-energizes. Subsequent high-level pulses on CH1 will repeat this function.

6. Programming and Configuration

The FRM01 module is configured using the onboard buttons: SET, SWI, NUM+, and NUM-. The display shows the current mode and timing parameters (T1, T2).

6.1 Button Functions:

• SET: Enters programming mode, confirms selections, and saves settings.
• SWI: Switches between different parameters (e.g., T1, T2, operating mode) within programming mode.
• NUM+: Increases the value of the currently selected parameter.
• NUM-: Decreases the value of the currently selected parameter.

6.2 General Programming Steps:

1. Enter Programming Mode: Press and hold the SET button for a few seconds until the display changes, indicating entry into programming mode.
2. Select Operating Mode: Use NUM+ or NUM- to cycle through the available operating modes. The display will typically show a code representing the mode (e.g., P-1, P-2, etc.). Refer to the product documentation for specific mode codes.
3. Confirm Mode: Press SET to confirm the desired operating mode.
4. Adjust Timing Parameters (T1, T2): After selecting the mode, the display will show T1. Use NUM+ and NUM- to adjust its value. Press SWI to switch to T2 (if applicable for the selected mode) and adjust its value.
5. Set Time Unit: Some modes may allow setting the time unit (seconds, minutes, hours). Use SWI to cycle through units and NUM+/NUM- to select.
6. Save and Exit: Press and hold SET again to save all settings and exit programming mode. The module will then operate according to the new configuration.

Note: Specific mode codes and parameter sequences may vary. It is recommended to refer to the detailed programming guide provided with the product for precise instructions.

7. Maintenance

The FRM01 module is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:

• Keep Clean: Periodically clean the module with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or solvents.
• Environmental Protection: Ensure the module is protected from excessive moisture, corrosive gases, and extreme temperatures.
• Connection Integrity: Periodically check all wiring connections to ensure they remain secure and free from corrosion.
• Avoid Physical Stress: Do not subject the module to excessive vibration or mechanical shock.
