Voltage and Current Warnings
UNITOUR monitors the input voltages of all 3 input phases and the neutral. You can set
voltage limits that will protect the connected loads by switching off the relevant outputs and
activating an alarm if the input voltages are outside of the set limits. Voltages outside the limits
are shown in red.
UNITOUR monitors the input currents of all 3 input phases and the neutral. You can set a
current warning alarm for each input phase and the neutral. An alarm is activated if a warning
level is reached. Currents above the warning levels are shown in yellow.
See section 3.19
Hint: You can also set load and leakage current warning alarms for each output channel. See
section 3.8.1
