5 PERIODIC TESTS
This test is used to check all outputs of the relay. It is a convenient way to determine proper system connec-
tions and verify the operation of all relay contacts, without having to apply currents and voltages to simulate
faults.
If DGP-Link is used to perform this test, the outputs will not operate unless jumper J1 on the
MMI module is removed. Refer to Figure 3–4: DGP MMI MODULE on page 3–5 .
NOTE
1. Connect the relay as shown in Figure 4–3: DIGITAL OUTPUT TEST CONNECTIONS on page 4–12.
2. Enter the Control Level password.
3. Press the [ACT] key and then select DIG OUT TEST. Press the [ENT] key.
4. Select the output to test. Use the arrow keys to scroll to the desired output, such as 94G, and press the
[ENT] key.
Before the contact is allowed to close, you will be prompted to turn protection off during the test. The
prompt is: DISABLE PROT?. Press the [1/Y] key followed by the [ENT] key to turn protection off. Protec-
tion will remain off until the test mode is ended.
Verify that the output under test has closed, using an ohmmeter or other suitable device.
5. After the output is tested, scroll to the next output to test, then press the [ENT] key. This output will close
and the previously selected output will open. Continue in this fashion until all outputs are tested.
6. End the test mode by scrolling to the END TEST MODE selection, then press the [ENT] key. Alternatively,
[END] followed by the [ENT] can be pressed to end the test and re-enable protection.
