Figur 3.1: Frontpanel
This image displays the front panel of the MC901-611. It features two digital displays: PV (Process Value) in red, showing the current temperature, and SV (Set Value) in green, showing the target temperature. Below the displays are indicator lights for OUT (Output), AT (Auto-tuning), ALM1 (Alarm 1), and ALM2 (Alarm 2). The control buttons include SET, R/S (Run/Stop), Down arrow, and Up arrow.

Figure 3.2: Side Panel with Specifications Label
This image shows the side of the MC901-611, highlighting the product label. The label provides crucial information such as Model (MC901-611), Input type (K, default setting), Temperature Range (0-1300°C), Temperature Unit (Celsius/Fahrenheit), Output type (Relay/SSR), Alarm (ALM1), Accuracy Class (0.5), and Power Supply (100-240V AC, 50/60Hz).

Figure 3.3: Rear Panel with Terminal Block
This image displays the rear of the MC901-611, featuring the terminal block for electrical connections. The terminals are clearly numbered, indicating where to connect power, sensor inputs, and control outputs. Proper wiring according to the provided diagram is essential for safe and correct operation.
The MC901-611 is designed for panel mounting. Ensure the cutout dimensions in your panel match the device's specifications.

Figur 4.1: Monteringsbeslag
This image shows the two mounting brackets included with the MC901-611. These brackets are used to secure the temperature controller firmly within a panel cutout, ensuring stable installation.
Refer to the wiring diagram on the side of the unit or in the detailed manual for correct connections. Ensure all connections are secure and insulated.
Note: A detailed wiring diagram is typically provided on the physical unit or in a separate wiring guide. Always consult the specific diagram for your model.
Once wired correctly, apply power to the unit. The PV display will show the current temperature, and the SV display will show the last set temperature.
To access advanced parameter settings (e.g., input type, control mode, alarm settings):
Consult the full product manual for a complete list of parameter codes and their functions.
Auto-tuning helps the controller optimize its PID parameters for stable and accurate temperature control. This process is recommended after initial setup or if control performance is unsatisfactory.
Regular maintenance ensures the longevity and optimal performance of your MC901-611 temperature controller.
This section addresses common issues you might encounter with your MC901-611 temperature controller.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen visning/Slukning | Ingen strømforsyning; Løse ledninger; Sprunget sikring. | Check power connection; Verify wiring; Replace fuse if necessary (by qualified personnel). |
| PV display shows "HHHH" or "LLLL" | Sensor open circuit (HHHH); Sensor short circuit or reverse connection (LLLL); Sensor type mismatch. | Check sensor wiring and connections; Ensure correct sensor type is selected in parameters. |
| Temperature not controlled accurately | Incorrect PID parameters; Sensor not properly installed; Load capacity mismatch. | Perform auto-tuning; Ensure sensor is in good thermal contact with the process; Verify output capacity matches load. |
| Output indicator (OUT) not lighting up | SV is equal to PV (no control action needed); Output wiring issue; Internal fault. | Check SV and PV values; Inspect output wiring; If problem persists, contact support. |
Hvis problemet fortsætter efter at have forsøgt disse løsninger, bedes du kontakte kundesupport.
