4. Setup and Installation

4.1 Unpacking

1. Carefully remove the controller from its packaging.
2. Inspect the unit for any signs of damage during transit. If damage is found, do not install and contact your supplier.
3. Verify that all components listed in the packing slip are present.

4.2 Mounting

The E5CC-QX2ASM-800 is designed for 1/16 DIN panel mounting. Ensure adequate space for ventilation and access to wiring terminals. Refer to the product's dimensional drawings for precise panel cutout requirements.

4.3 Wiring

All wiring should be performed by a qualified electrician in accordance with local and national electrical codes. Ensure power is disconnected before making any connections.

• Power Supply: Connect the 100-240 VAC, 50/60 HZ power supply to the designated terminals.
• Input Sensor: Connect the temperature sensor (e.g., thermocouple, RTD) to the input terminals. Ensure correct polarity for thermocouples.
• Control Output: Connect the control output (e.g., relay, voltage, current) to the heating or cooling element as required by your application.
• Alarm Outputs: If utilized, connect alarm outputs to external alarm devices.

5. Operating Instructions

5.1 Powering On

After completing all wiring and mounting, apply power to the controller. The display will illuminate, typically showing the current process value (PV) and the set value (SV).

5.2 Basic Operation

The controller continuously monitors the process value from the input sensor and adjusts the output to maintain the set value. The large digital display shows the current temperature (PV) and the desired temperature (SV).

5.3 Parameter Settings

The E5CC-QX2ASM-800 features various parameters for fine-tuning control, alarm settings, and input types. Accessing and modifying these parameters typically involves pressing specific buttons (e.g., Mode, Up, Down) in a sequence. Refer to the detailed programming guide (usually a separate document or advanced section of the manual) for specific parameter codes and adjustment procedures.

6. Maintenance

6.1 Cleaning

To clean the controller, gently wipe the front panel with a soft, dry cloth. For stubborn dirt, use a cloth lightly dampened with water or a mild, non-abrasive cleaner. Do not use solvents, alcohol, or abrasive materials, as these can damage the display or casing.

6.2 Inspection

Periodically inspect the wiring connections for tightness and signs of corrosion. Ensure the controller's ventilation openings are clear of obstructions. Check for any unusual noises or odors coming from the unit, which could indicate a malfunction.

7. Troubleshooting

This section provides solutions to common issues. For problems not listed here, or if the issue persists, contact Omron technical support.

• No Power: Check power supply connections and ensure the circuit breaker is not tripped. Verify input voltage is within the 100-240 VAC range.
• Incorrect Temperature Reading: Verify the sensor type setting matches the connected sensor. Check sensor wiring for breaks or short circuits. Ensure the sensor is correctly placed in the process.
• Output Not Activating: Check the set value (SV) and process value (PV). Verify control mode settings (e.g., heating/cooling). Inspect output wiring and the connected load.
• Alarm Not Triggering: Check alarm setpoints and hysteresis settings. Verify alarm output wiring.
