5.7.6.4 Test digital inputs
Digital inputs are tested using Diagnostic menu. In submenu Digital I/O all digital inputs and outputs are presented. By
triggering digital input with external source the corresponding DI on the LCD is marked. In order to pass the test each
digital input should be tested.
1.) Connect digital inputs according to scheme on Figure 5.7 for current measuring inputs or Figure 5.8 for voltage
measuring inputs to external DC power supply.
2.) Trigger each digital input with rated DC voltage.
3.) Monitor triggered digital inputs through LCD Digital I/O menu.
Test is successful if each digital input can be triggered and monitored.
In case of input being connected to control
function or even circuit breaker control
during testing imminent danger is
presented.
5.7.6.5 Analog measuring test
Never open the secondary circuits of CT
when the current transformer is energized.
Before disconnecting the current circuits,
always short circuit the CT secondary
circuits. Omitting that instruction can
result in lethal hazard and equipment
insulation deterioration due to high
voltage inductions!
Tests with currents exceeding
4 times the nominal device
current cause an overload of
the input circuits.
Short circuit secondary circuit of CT.
Disconnect CT secondary circuits from device.
Connect generator to testing analog input.
Turn on the generator.
Inject the CT secondary rated current (1 A or 5 A).
Read HMI measurements or MiQen software to check that device measures approximately the same RMS value.
Repeat the test for all analog inputs.
5.7.6.6 Key sound test
Key sound is tested by turning it on or off in User interface submenu of the device setting menu. When turned on each
press on HMI key triggers a sound. When turned off pressing HMI key does not trigger a sound.
Test is passed if key sound can be turned on and off.
5.7.6.7 Communication via USB
Connect device to computer with installed MiQen software through front USB port.
