- Tout fil elektrik ta dwe fèt pa yon elektrisyen kalifye.
- Disconnect power before making any wiring connections or performing maintenance.
- Do not operate the controller in environments with excessive moisture, dust, or corrosive gases.
- Asire bon vantilasyon pou anpeche surchof.
- This device is not intended for life-support systems or applications where malfunction could lead to severe injury or property damage.
4. Enstalasyon ak Enstalasyon
Proper installation is crucial for the accurate and reliable operation of the MC701 controller.
4.1 Montaj
The MC701 is designed for panel mounting. Ensure adequate space for ventilation and wiring connections.

4.2 Koneksyon fil elektrik
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. Operasyon Enstriksyon
5.1 Ekspozisyon souview
The MC701 features a dual display:
- PV (Process Value): Displays the current measured temperature.
- SV (Set Value): Displays the desired target temperature.
Limyè endikatè:
- OUT: Indicates output status (heating/cooling).
- AT: Auto-tuning indicator.
- ALM1, ALM2: Alarm indicators.
5.2 Fonksyon bouton
- 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 Fikse Tanperati Sib la (SV)
- Peze a SET bouton an yon fwa. Ekran SV a ap kòmanse flache.
- Sèvi ak la ^ epi V bouton pou ajiste tanperati a vle.
- Sèvi ak la < button to shift the cursor for faster adjustment.
- Peze SET again to confirm the new SV and exit the setting mode.
5.4 Advanced Parameter Settings
To access advanced parameters (e.g., PID parameters, alarm settings, input type, temperature unit), press and hold the SET button for several seconds until the first parameter code appears on the PV display.
- Sèvi ak ^ epi V to navigate through parameters.
- Peze SET pou view or edit a parameter's value.
- Ajiste valè a lè l sèvi avèk ^, V, ak <.
- Peze SET to save the value and return to the parameter list.
- To exit advanced settings, press and hold SET again, or wait for a timeout.
6. Antretyen
Regular maintenance ensures the longevity and optimal performance of your MC701 controller.
- Cleaning: Wipe the display and casinSiye ak yon twal mou epi sèk. Pa sèvi ak pwodui netwayaj abrazif oswa solvan.
- 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.
NAN. Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Display shows "HHHH" or "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. |
| Controller not heating/cooling | 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. |
| Temperature fluctuates widely | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| Pa gen pwoblèm ekspozisyon/kouran | Pa gen kouran; fil elektrik ki pa kòrèk. | Check power connections (terminals 8 & 9). Verify power source is active. |
