2. Safety Instructions

WARNING: Risk of electric shock. Installation and maintenance must be performed by qualified personnel only. Disconnect power before working on the device.

• Ensure all local and national electrical codes are followed during installation.
• Verify that the power supply voltage matches the device's specifications.
• Do not operate the device if it appears damaged.
• Protect the device from moisture, dust, and extreme temperatures.

3. Product Overview

The ABB 1SVR730700R2200 is a compact temperature monitoring relay designed for DIN rail mounting. It provides continuous monitoring of temperature and activates its output contacts upon detecting deviations from set thresholds.

Figure 3.1: Front view of the ABB 1SVR730700R2200 Temperature Monitoring Relay. The image shows the device with terminal connections labeled A1, 11, 21, A3, T2, T1, 24, 22, S1, and 14. The model number CM-MSS 23S and 1SVR730700R2200 are visible on the side label, along with various certifications and electrical ratings. The front panel includes a 'Reset' button and indicators for 'U' (supply voltage) and 'F' (fault).

Key Components:

• Terminals: For power supply, sensor input, and output contacts (e.g., A1, A3 for supply; T1, T2 for sensor; 11, 14, 21, 22, 24 for contacts).
• Indicators: LEDs for status indication (e.g., 'U' for supply voltage, 'F' for fault).
• Reset Button: To clear fault conditions.
• Settings (if applicable): Dials or switches for threshold adjustment.

4. Installation and Setup

4.1 Mounting

The relay is designed for mounting on a standard 35mm DIN rail. Ensure sufficient space around the device for ventilation and access to terminals.

1. Hook the top edge of the relay onto the DIN rail.
2. Press the bottom edge of the relay firmly until it clicks into place.
3. Verify that the relay is securely fastened to the DIN rail.

4.2 Wiring

Refer to the wiring diagram on the side of the device and the following instructions for correct connections. Use appropriate wire gauges for the current and voltage ratings.

• Power Supply (A1, A3): Connect the appropriate AC voltage (110-130Vac or 220-240Vac) to terminals A1 and A3. Ensure the voltage matches the device's rating.
• Sensor Input (T1, T2): Connect the temperature sensor (e.g., PTC thermistor) to terminals T1 and T2.
• Output Contacts (11, 14, 21, 22, 24): The relay features two changeover (SPDT) contacts.
  • Contact 1: Common (11), Normally Open (14).
  • Contact 2: Common (21), Normally Closed (22), Normally Open (24).
  Connect the controlled circuit to these terminals as required by your application.

Note: The image shows terminals 11, 21, A1, A3, T2, T1 on the top, and 24, 22, S1, 14 on the bottom. The internal diagram shows 11-14 (NO), 21-22 (NC), 21-24 (NO).

5. Operating Instructions

5.1 Initial Power-Up

1. After completing all wiring, apply power to the A1 and A3 terminals.
2. The 'U' (supply voltage) indicator LED should illuminate, indicating that the device is powered.
3. The relay will perform a self-test. If the temperature is within the normal operating range and no fault is detected, the output contacts will be in their normal state.

5.2 Monitoring and Fault Indication

The relay continuously monitors the temperature via the connected sensor. If the temperature exceeds or falls below the configured thresholds (internal or external to the sensor type), a fault condition will be triggered.

• When a fault occurs, the 'F' (fault) indicator LED will illuminate.
• The output contacts will change state according to the configured relay function (e.g., normally open contacts close, normally closed contacts open).

5.3 Resetting the Relay

After a fault condition has been resolved, the relay can be reset.

• Manual Reset: Press the 'Reset' button on the front panel.
• Automatic Reset: Some configurations may allow for automatic reset once the temperature returns to the normal range. Refer to the specific product variant documentation for details on automatic reset functionality.

6. Maintenance

The ABB 1SVR730700R2200 is designed for maintenance-free operation under normal conditions. However, periodic checks are recommended to ensure optimal performance and longevity.

• Cleaning: Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Terminal Connections: Periodically check all terminal connections for tightness to prevent loose contacts, which can lead to overheating or intermittent operation.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges.
