Output Contact And Input Circuit Verification Test - ABB REL 301 Instruction Leaflet

The significant quantities to review are:
Using the same test connection, as above, the system should not trip at any of the following an-
gles of I
A
• All angles between +3° and +177°
• Or +90° ± 87°, where +90° could be referred to as the zero torque angle
5.1.7 Output Contact and Input Circuit Verification Test
STEP 11
The purpose of this test is to check the hardware connections, output relay contact operation,
and input circuit verification.
To perform these tests, jumper #5 (JP5) on the microprocessor module, must be in place. (Refer
to paragraph entitled "Acceptance Test" at the beginning of this chapter for details.) Jumper #3
(JP3) is a spare jumper which is moved to the JP5 position for this test. Upon test completion,
if front panel output contact operation is not desired, remove JP5 and return it to the JP3 posi-
tion.
Press the S
read "STATUS" "0" indicating the self-checking/startup/initialization routine was completed
successfully and the system is continuously passing the self-checking routine. Press the R
push-button and scroll to contact output to be tested. All contact outputs can be tested. See the
"CONNECTION SPECIFICATION CHART" in Section 4.3 and "Relay Output Test" in Section
4.4.2.1 for contact listing and terminal references.
After scrolling to the contact output to be tested, for example "Trip" "Relay", pressing the EN-
TER push-button will cause the trip relay to operate and hence the trip contacts to close. A sim-
ilar procedure is used to test any contact output.
NOTE:
In the "TEST" mode verification of the LEDs functioning is accomplished by scrolling to the
"LEDs" "Protection" display and pressing the E
light in the following sequence and remain lit while the E

Testing of the trip contacts generates a target which is reported as simply
"Test" in the display. Trip contact testing is the only contact test which gener-
