- Disconnect power before making any wiring connections or performing maintenance.
- Do not operate the controller in environments with excessive moisture, dust, or corrosive gases.
- Garantire una ventilazione adeguata per evitare il surriscaldamento.
- This device is not intended for life-support systems or applications where malfunction could lead to severe injury or property damage.
4. Configurazione e installazione
Proper installation is crucial for the accurate and reliable operation of the MC701 controller.
4.1 Montaggio
The MC701 is designed for panel mounting. Ensure adequate space for ventilation and wiring connections.

Figure 4.1: MC701 controller shown with its included mounting clips for panel installation.
4.2 Collegamenti di cablaggio
Refer to the wiring diagram on the side of the unit and the instructions below for correct connections. Use appropriate gauge wires for all connections.

Figure 4.2: Detailed wiring diagram on the side of the MC701 unit, showing connections for power, sensor input, SSR, and relay outputs.
- Power Supply (85-265VAC): Connect to terminals 8 and 9.
- SSR Output (OUT): Connect to terminals 10 (+) and 11 (-).
- Relay Output (RELAY): Connect to terminals 13 (NO - Normally Open) and 14 (NC - Normally Closed). Terminal 12 is the common (COM).
- RTD Input (PT100): Connect to terminals 4 (A), 5 (B), and 6 (B).
- Thermocouple Input (TC): Connect to terminals 5 (+) and 6 (-).
- Alarm Outputs (AL1, AL2): Connect to terminals 1, 2, and 3.
5. Istruzioni per l'uso
5.1 Fine displayview
The MC701 features a dual display:
- PV (Process Value): Displays the current measured temperature.
- SV (Set Value): Displays the desired target temperature.
Spie luminose:
- OUT: Indicates output status (heating/cooling).
- AT: Auto-tuning indicator.
- ALM1, ALM2: Alarm indicators.
5.2 Funzioni dei pulsanti
- SET: Enters parameter setting mode or confirms a setting.
- < (R/S): Shifts cursor during setting, or resets alarm.
- V (Down Arrow): Decreases value during setting.
- ^ (Up Arrow): Increases value during setting.
5.3 Setting the Target Temperature (SV)
- Premere il tasto IMPOSTATO button once. The SV display will start flashing.
- Utilizzare il ^ E V pulsanti per regolare la temperatura desiderata.
- Utilizzare il < pulsante per spostare il cursore e ottenere una regolazione più rapida.
- Premere IMPOSTATO again to confirm the new SV and exit the setting mode.
5.4 Impostazioni avanzate dei parametri
To access advanced parameters (e.g., PID parameters, alarm settings, input type, temperature unit), press and hold the IMPOSTATO button for several seconds until the first parameter code appears on the PV display.
- Utilizzo ^ E V to navigate through parameters.
- Premere IMPOSTATO A view or edit a parameter's value.
- Regolare il valore utilizzando ^, V, E <.
- Premere IMPOSTATO to save the value and return to the parameter list.
- To exit advanced settings, press and hold IMPOSTATO again, or wait for a timeout.
6. Manutenzione
Regular maintenance ensures the longevity and optimal performance of your MC701 controller.
- Cleaning: Wipe the display and casing con un panno morbido e asciutto. Non utilizzare detergenti abrasivi o solventi.
- Ventilation: Ensure the ventilation slots on the sides of the unit are not obstructed to prevent overheating.
- Connections: Periodically check all wiring connections for tightness and signs of wear or corrosion.
- Storage: If storing the unit, keep it in a dry, dust-free environment within its specified operating temperature range.
7. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il display mostra "HHHH" o "LLLL" | Sensor open circuit or short circuit; temperature exceeds range. | Check sensor wiring and connection. Verify sensor type matches setting. Ensure temperature is within range. |
| Il controller non riscalda/raffredda | Output wiring incorrect; SV not set correctly; PID parameters need tuning. | Check output wiring (SSR/Relay). Confirm SV is set to desired temperature. Perform auto-tuning if necessary. |
| La temperatura oscilla ampiamente | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| No display/Power issue | Nessuna alimentazione; cablaggio errato. | Check power connections (terminals 8 & 9). Verify power source is active. |
