5. Setup
5.1 Mounting
The MC101-611 is designed for panel mounting. Cut an appropriate opening in your control panel and insert the meter. Secure it from the rear using the provided mounting bracket. Ensure a snug fit to prevent vibration.
5.2 Wiring
Refer to the wiring diagram on the side of the unit and Figure 5.1 for correct connections. Ensure all connections are secure and insulated. Incorrect wiring can damage the device or pose a safety hazard.
- Terminals 1 & 2: AC Power Supply (85-265V AC, 50/60Hz)
- Terminals 3 & 4: Main Output (OUT) - Normally Open (NO) and Normally Closed (NC) contacts for Relay output.
- Terminals 6 & 7: Alarm Output (ALM) - Relay contacts for alarm.
- Terminals 8, 9, 10: Sensor Input (RTD/TC) - Connect your temperature sensor here. Refer to the sensor's manual for correct polarity/connection type.
- Terminals 11 & 12: SSR Output - For connecting to a Solid State Relay.

6. Operating Instructions
6.1 Display Overview
The meter features a dual display:
- PV (Process Value): The upper red display shows the current measured temperature/humidity.
- SV (Set Value): The lower green display shows the desired set point.
- OUT Indicator: Illuminates when the main output is active.
- AT Indicator: Illuminates when the auto-tuning function is active.
- AL1/AL2 Indicators: Illuminate when Alarm 1 or Alarm 2 conditions are met.
6.2 Button Functions
- SET Button: Used to enter parameter setting mode and confirm selections.
- < / R/S Button: Used to shift digits during setting or to reset alarms.
- ▼ (Down) Button: Decreases the value of a parameter or set point.
- ▲ (Up) Button: Increases the value of a parameter or set point.
6.3 Setting the Temperature/Humidity Set Point (SV)
- In normal operating mode, press the SET button once. The SV display will begin to flash.
- Use the ▲ (Up) and ▼ (Down) buttons to adjust the SV to your desired value. Use the < / R/S button to shift the cursor for faster adjustment.
- Press the SET button again to confirm the new SV and exit the setting mode.
6.4 Advanced Parameter Settings
To access advanced parameters (e.g., input type, control mode, alarm settings, PID parameters), press and hold the SET button for approximately 3-5 seconds until the first parameter code appears on the PV display. Use the ▲ (Up) and ▼ (Down) buttons to navigate through parameters and the SET button to enter and confirm values. Refer to the detailed parameter list in the full technical manual for specific codes and their functions.
7. Maintenance
- Cleaning: Wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check wiring connections for looseness or corrosion.
- Storage: If storing the device for an extended period, ensure it is kept in a dry, dust-free environment within its specified storage temperature range.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; Incorrect wiring; Device fault. | Check power connections and voltage; Verify wiring according to diagram; Contact support if problem persists. |
| PV display shows 'HHHH' or 'LLLL' | Sensor open circuit (HHHH) or short circuit (LLLL); Sensor not connected; Incorrect sensor type setting. | Check sensor wiring; Ensure sensor is connected; Verify sensor type setting in parameters matches connected sensor. |
| Output not activating | SV not reached; Control mode incorrect; Output wiring issue. | Adjust SV; Check control mode (e.g., heating/cooling); Verify output wiring. |
| Temperature reading is inaccurate | Sensor calibration needed; Sensor damaged; External interference. | Perform sensor calibration (if supported); Replace sensor; Relocate device away from interference sources. |
