Detailed wiring diagram for JOCCOS XMTD-2201

Figure 5.2: Detailed wiring diagram for the JOCCOS XMTD-2201. This diagram illustrates the connections for the thermocouple (terminals 1 and 2, with 1 being positive and 2 negative), power supply (terminals 11 and 12 for 220V), and the relay output (terminals 7, 8, 9 for common, normally closed, and normally open contacts respectively). It also includes a basic working principle block diagram.

Wiring Key:

Terminals 1 & 2: Thermocouple input (1: Positive, 2: Negative). Ensure correct polarity for PT100 sensor.
Terminals 11 & 12: 220V AC Power Supply input.
Terminals 7, 8, 9: Relay Output. These are typically used for controlling external heating or cooling elements.
- Terminal 7: Common (C)
- Terminal 8: Normally Closed (NC)
- Terminal 9: Normally Open (NO)
Terminal 10: Ground connection.

Warning: Incorrect wiring can damage the device or cause electrical hazards. Always consult a qualified electrician.

6. Operation

6.1 Powering On

After completing all wiring, apply 220V AC power to terminals 11 and 12. The digital display will illuminate, showing the current measured temperature.

6.2 Setting Temperature Limits

The XMTD-2201 features rotary potentiometers for setting upper and lower temperature limits. These are typically adjusted using a small screwdriver.

Upper Limit Setting: Rotate the potentiometer labeled "上限设定" (Upper Limit Setting) to adjust the maximum desired temperature. The display will show the set value as you adjust.
Lower Limit Setting: Rotate the potentiometer labeled "下限设定" (Lower Limit Setting) to adjust the minimum desired temperature. The display will show the set value as you adjust.

The controller will activate or deactivate the relay output based on the measured temperature relative to these set limits, maintaining the temperature within the defined range.

6.3 Display Indicators

Digital Display: Shows the current measured temperature.
ON/OFF Indicator: Indicates the status of the control output (e.g., relay active/inactive).

7. Maintenance

Cleaning: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
Inspection: Regularly inspect wiring connections for looseness or signs of damage. Tighten connections as needed.
Environmental Check: Ensure the operating environment remains within specified conditions (temperature, humidity, absence of corrosive gases).
Sensor Check: Verify the PT100 sensor is free from damage and properly installed. A faulty sensor can lead to inaccurate readings.

Caution: Always disconnect power before performing any maintenance.

8. Troubleshooting

Problem	Possible Cause	Solution
No display/No power	No power supply Incorrect wiring Blown fuse (internal/external)	Check 220V AC power supply. Verify wiring to terminals 11 & 12. Inspect and replace fuse if necessary (by qualified personnel).
Inaccurate temperature reading	Faulty sensor Incorrect sensor type Loose sensor connection Sensor not properly placed	Replace sensor. Ensure PT100 sensor is used. Check connections to terminals 1 & 2. Relocate sensor to a representative measurement point.
Control output not activating	Temperature within deadband Incorrect set limits Faulty relay Incorrect output wiring	Adjust set limits or observe temperature trend. Verify upper and lower limit settings. Test relay (by qualified personnel). Check wiring to terminals 7, 8, 9.
