10.6.6 Test the Binary Inputs
The purpose of this test is to check whether the connection of binary input circuit is correct. During
the test, the voltage applied to the binary input terminal must be within the allowable operating
range.
Each binary input status can be checked by the device LCD panel, and the status "1" indicates that
the binary input has been applied with an input voltage, and the opening status becomes "0" when
the input voltage disappears.

10.6.7 Test the Binary Outputs
The purpose of this test is to check whether the binary output circuit connection is correct.
According to the protection logic of the device and various kinds of signal output logic, stimulate a
fault condition. The corresponding relay contact of the device shall be operated with the
corresponding action or alarm signal.
10.6.8 Protection Function Checks
The purpose of this experiment is to verify the correctness of the protection logic. Protection
function tests generally include the following types:
• Impedance protection test
• Current protection test
• Voltage protection test
• Frequency protection test
• Secondary system supervision function test
For details on how to implement the protection logic function, refer to "Operation Theory"
10.6.9 Printing Function Checks
Check the printer cable is connected properly before printing, printing paper is complete. Printing
method can be set to "automatic" or "manual". When set to automatic printing, the device will print
protection action event, self- checking information and other records initiatively in real time.
10.6.10 On-load Checks
The objectives of the on-load checks are:
• Confirm the external wiring to the current and voltage inputs is correct.
