5.2 Bedradingsdiagram
Refer to the wiring diagram below for correct electrical connections. Ensure all connections are secure and comply with local electrical codes. The controller operates on 110VAC.
Figure 5.3: Wiring diagram for the MTC-5060 controller. Terminals 1-2 for power, 3-5 for sensors, 6-9 for output loads (cooling and defrosting).
- Kragtoevoer: Connect 110VAC to terminals 1 and 2.
- Sensorverbindings: Connect the NTC sensor(s) to the designated terminals (e.g., 3, 4, 5). The MTC-5060 supports two sensors for storage temperature and defrosting temperature.
- Uitsetladings: Connect cooling and defrosting loads to the respective relay output terminals (e.g., 7-8 for cooling, 8-9 for defrosting). The relay output contact capacity is 3A/110VAC.
6. Bedryfsinstruksies
The MTC-5060 features a user-friendly interface with dedicated buttons for common functions and parameter settings.
6.1 Vertoon en aanwysers
The controller has two digital displays:
- Boonste skerm: Toon die huidige kamertemperatuur.
- Onderste skerm: Toon die ingestelde temperatuur.
Indicator lights provide visual feedback on the operating mode (e.g., cooling, defrosting).
6.2 Stel temperatuur
- Druk die Stel knoppie om view die huidige ingestelde temperatuur.
- While the set temperature is displayed, use the Up en Af arrow buttons to adjust the desired temperature value.
- Druk die Stel button again to confirm and save the new setting.
6.3 Defrosting Control
The MTC-5060 supports automatic and manual defrosting.
- Outomatiese ontdooiing: Configured through parameters (defrost cycle, defrost time). Refer to the detailed parameter settings section (if available in full manual) for adjustment.
- Handmatige ontdooiing: Druk die Forced Def. button to initiate a manual defrost cycle.
Figure 6.1: Illustrates the "Forced Def." button for manual defrost initiation.
6.4 Parameterinstellings
Advanced parameters such as compressor delay, defrost cycle, defrost time, and temperature calibration can be accessed and adjusted. Consult the full product manual for a complete list of parameters and their functions.
Note: Incorrect parameter settings can affect the performance and safety of your refrigeration system. Proceed with caution when adjusting advanced settings.

9. Probleemoplossing
This section provides solutions to common issues you might encounter with your MTC-5060 controller.
| Probleem | Moontlike oorsaak | Oplossing |
|---|---|---|
| Beheerder skakel nie aan nie. | Geen kragtoevoer of verkeerde bedrading. | Check power connections (terminals 1 & 2) and ensure 110VAC supply. Verify wiring against diagram. |
| Temperature display is inaccurate or shows "EE". | Sensor error or faulty sensor. | Check sensor connections. Ensure the sensor is not damaged. Replace sensor if necessary. Perform temperature calibration if readings are consistently off. |
| Cooling/Defrosting not activating. | Incorrect set temperature, parameter settings, or faulty output relay. | Verify set temperature and differential. Check relevant parameters (e.g., compressor delay, defrost cycle). Inspect wiring to the cooling/defrosting load. |
| High/Low temperature alarm triggers frequently. | Alarm limits set too close to operating temperature or actual temperature fluctuation. | Adjust high/low temperature alarm limits. Investigate the cause of temperature fluctuations in the controlled environment. |
If the problem persists after attempting these solutions, please contact Elitech customer support for further assistance.
