4. Setup agus Stàladh
Proper installation is crucial for the accurate and reliable operation of the MC701 controller.
4.1 Stàladh
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 Ceanglaichean Uèiridh
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. Stiùireadh Obrachaidh
5.1 Taisbeanadh thairisview
The MC701 features a dual display:
- PV (Process Value): Displays the current measured temperature.
- SV (Set Value): Displays the desired target temperature.
Solais comharra:
- OUT: Indicates output status (heating/cooling).
- AT: Auto-tuning indicator.
- ALM1, ALM2: Alarm indicators.
5.2 Gnìomhan Putan
- 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)
- Brùth an SET brùth air a’ phutan aon uair. Tòisichidh taisbeanadh SV a’ priobadh.
- Cleachd an ^ agus V putanan gus an teòthachd a tha thu ag iarraidh atharrachadh.
- Cleachd an < button to shift the cursor for faster adjustment.
- Brùth 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.
- Cleachd ^ agus V gus seòladh tro pharaimearan.
- Brùth SET gu view or edit a parameter's value.
- Atharraich an luach a 'cleachdadh ^, V, agus <.
- Brùth 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. Cumail suas
Regular maintenance ensures the longevity and optimal performance of your MC701 controller.
- Cleaning: Wipe the display and casinle clò bog, tioram. Na cleachd innealan-glanaidh sgrìobach no fuasglaidhean.
- 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. A ’dèanamh trioblaid
| Trioblaid | Adhbhar a dh’fhaodadh a bhith ann | Fuasgladh |
|---|---|---|
| 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. |
| Bidh an teòthachd ag atharrachadh gu farsaing | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| No display/Power issue | Gun solar cumhachd; uèirleadh ceàrr. | Check power connections (terminals 8 & 9). Verify power source is active. |
