What to do if Shimax MAC6A Controller shows scale over in upper limit?
- AagarciaAug 13, 2025
If the Shimax Controller displays a scale over in the upper limit, it could be due to a few reasons: 1. There might be a wire break in the thermocouple input. Check the thermocouple input wiring and consider replacing the thermocouple. 2. There might be a wire break in the resistance bulb input A. Check the wiring of resistance bulb A and consider replacing it. 3. The input might be exceeding the upper limit of the measuring range by 10%. Verify the input voltage and current values, and ensure that the input transmitter and controller specifications match.
