Before applying the input voltages, check the jumper positions on the Inter-connect
module for the rated voltage selections and check JMP7 and JMP9 for the STUB
(SBP) input test. On the Microprocessor module, remove JMP12 (spare) and place
it in the JMP5 position.
Change the LED mode to "TEST" and select the function field to OPTI. Apply a rat-
ed voltage to TB5 appropriate terminals and a non-zero HEX value should be
shown on the right-hand side display as follows:
Term
(TB5)
7(+), 8 *
11(+), 12 *
9(+), 10 *
13(+), 14
1(+), 2 *
3(+), 4
5(+), 6
* Optional
This Completes the OPTO Input Hardware Check.
The purpose of this test is to check the hardware connections and relay contacts.
It is designed for a bench test only. Remove JMP12 (spare on the Microprocessor
PC Board) and place it in the JMP 5 position.
Change the LED mode to "TEST" and select the tripping function field and the de-
sired contact in the value field. Push the ENTER button; the ENTER LED should
be "ON". The corresponding relay should operate when the ENTER button is
pressed. The following contacts can be tested:
• TRIP
• BFI
• RI1 (optional)
• RI2
• RB
• AL1 (with 3 balanced voltages)
• AL2
• GS
• SEND (optional)
