Product Overview
The ICM Controls ICM203F is a versatile delay-on-break timer designed for various electrical applications. It features an adjustable time delay range from 0.03 to 10 minutes and is compatible with universal 18-240 VAC input. This device helps protect equipment by ensuring a delay before restarting after a power interruption, allowing for pressure equalization in systems like air conditioning compressors.

Setup and Installation
Safety First: Before beginning any installation, ensure that the power supply to the circuit is completely disconnected at the breaker or fuse box. Failure to do so can result in electrical shock, injury, or death.
- Identify Wiring: The ICM203F comes with six lead wires. Refer to the wiring diagram provided with your specific equipment or consult a qualified electrician for proper connection.
- Voltage Selection: The unit is designed for 18-240 VAC. If your application requires 120 VAC or 240 VAC, follow the instructions on the unit to 'CUT WIRE FOR 120/240 VAC' as indicated on the product label. This typically involves cutting a specific wire loop to configure the timer for the desired voltage.
- Connect Load: Connect the timer in series with the load you intend to protect. Ensure the load's current draw does not exceed 1.5 AM MAX.
- Secure Mounting: Mount the timer in a secure location, away from excessive heat, moisture, or vibration.
- Verify Connections: Double-check all wiring connections for tightness and correctness before restoring power.
Note: Incorrect wiring can damage the timer or the connected equipment. If you are unsure about any step, seek professional assistance.
Operating Instructions
The ICM203F is a delay-on-break timer, meaning it initiates a delay period when the power to the controlled circuit is interrupted and then restored. This prevents rapid cycling of equipment.
- Adjusting Time Delay: The red knob on the top of the unit allows you to set the delay time. Rotate the knob to select a delay period between 0.03 minutes (approximately 1.8 seconds) and 10 minutes. The markings around the knob provide a general guide for setting the desired delay.
- Functionality: When power to the timer is interrupted (e.g., a brief power outage), the timer will begin its delay countdown once power is restored. The connected equipment will not energize until the set delay period has elapsed. This protects sensitive equipment, such as air conditioning compressors, from short-cycling or attempting to restart against high head pressure.
Example: If set to 5 minutes, and power is lost and then restored, the connected equipment will remain off for 5 minutes before turning back on.
Maintenance
The ICM203F Delay On Break Timer is designed for maintenance-free operation. However, periodic inspection is recommended to ensure optimal performance and safety.
- Visual Inspection: Annually inspect the timer and its wiring for any signs of physical damage, corrosion, or loose connections.
- Cleaning: If necessary, gently wipe the exterior of the unit with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Environmental Conditions: Ensure the operating environment remains within the recommended temperature and humidity ranges to prevent premature failure.
Warning: Do not attempt to open the timer housing. There are no user-serviceable parts inside.
Troubleshooting
If the ICM203F timer is not functioning as expected, consider the following common issues and solutions:
- Timer Not Delaying:
- Verify the power supply to the timer is stable and within the 18-240 VAC range.
- Check if the time delay knob is set to a measurable delay (not at the absolute minimum if a delay is expected).
- Ensure the wiring is correct according to the installation instructions.
- Equipment Not Turning On After Delay:
- Confirm the load's current draw does not exceed 1.5 AM MAX. An overload could prevent activation.
- Check the connections to the load for looseness or corrosion.
- Test the connected equipment directly (bypassing the timer, if safe to do so) to rule out issues with the equipment itself.
- Timer Appears Dead:
- Check the main power supply to the circuit.
- Inspect all wiring connections for continuity and proper voltage.
- If the unit was configured for 120/240 VAC by cutting a wire, ensure this was done correctly for your voltage.
If troubleshooting steps do not resolve the issue, contact ICM Controls customer support or a qualified technician.
