4.2 Hononga Waea

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. Nga Tohutohu Whakahaere

5.1 Whakaatu i rungaview

The MC701 features a dual display:

• PV (Process Value): Displays the current measured temperature.
• SV (Set Value): Displays the desired target temperature.

Nga rama tohu:

• OUT: Indicates output status (heating/cooling).
• AT: Auto-tuning indicator.
• ALM1, ALM2: Alarm indicators.

5.2 Nga Mahi Patene

• 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)

1. Pehia te SET button once. The SV display will start flashing.
2. Whakamahia te ^ a V pātene hei whakatika i te pāmahana e hiahiatia ana.
3. Whakamahia te < button to shift the cursor for faster adjustment.
4. Perehi 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.

• Whakamahi ^ a V to navigate through parameters.
• Perehi SET ki view whakatika rānei i te uara o tētahi tawhā.
• Whakaritea te uara ma te whakamahi ^, V, a <.
• Perehi 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. Tiaki

Regular maintenance ensures the longevity and optimal performance of your MC701 controller.

• Cleaning: Wipe the display and casing me te kakahu ngohengohe, maroke. Kaua e whakamahi i nga kai horoi me nga whakarewa.
• 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.
