5. Opsette
5.1 Montage
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 Bedrading
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. Bedriuwsinstruksjes
6.1 Display oerview
The meter features a dual display:
- PV (Proseswearde): The upper red display shows the current measured temperature/humidity.
- SV (Ynstelde wearde): The lower green display shows the desired set point.
- OUT-yndikator: Illuminates when the main output is active.
- AT-yndikator: Illuminates when the auto-tuning function is active.
- AL1/AL2 Indicators: Illuminate when Alarm 1 or Alarm 2 conditions are met.
6.2 Knop Funksjes
- SET knop: Brûkt om de parameterynstellingsmodus yn te gean en seleksjes te befêstigjen.
- < / 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 knop ien kear yndrukke. It SV-display sil begjinne te knipperjen.
- Brûk de ▲ (Omheech) en ▼ (Down) buttons to adjust the SV to your desired value. Use the < / R/S button to shift the cursor for faster adjustment.
- Druk op de SET button again to confirm the new SV and exit the setting mode.
6.4 Avansearre parameterynstellingen
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 ▲ (Omheech) en ▼ (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. Underhâld
- Reiniging: Wiskje it skerm ôf en casinmei in sêfte, droege doek. Brûk gjin abrasive reinigingsmiddels of oplosmiddels.
- Ynspeksje: Kontrolearje de bedrading periodyk op losheid of korrosje.
- Opslach: 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. Probleemoplossing
| Probleem | Mooglike oarsaak | Oplossing |
|---|---|---|
| Display is leech | No power supply; Incorrect wiring; Device fault. | Kontrolearje stroomferbiningen en folumetage; Verify wiring according to diagram; Contact support if problem persists. |
| PV-display lit 'HHHH' of 'LLLL' sjen | 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. |
| Útfier wurdt net aktivearre | SV not reached; Control mode incorrect; Output wiring issue. | Adjust SV; Check control mode (e.g., heating/cooling); Verify output wiring. |
