TECHNICAL REFERENCE MANUAL DEK TQ 04/2021 69

Each circuit breaker has two channels, measuring the voltage before and after the circuit breaker.

Each channel displays the minimum, maximum and nominal voltages since the machine was last

powered up or Refresh Values was selected. The channel is displayed in red if the voltage is cur-

rently out of tolerance, amber if the voltage has previously been out of tolerance or green if the

voltage is and has stayed within tolerance.

Selecting a circuit breaker on the screen displays more information on that breaker in the bottom

left of the screen.
