ABB REL300 Instruction Manual page 104

For the opto-input hardware check, apply a rated dc voltage to any opto-input terminals. When
OPTI in function field is selected on the test mode, a non-zero HEX value will be shown in the
value field and is identified as follows:
Bit 0
Bit 1
Bit 2
Bit 3
Bit 4
Bit 5
Bit 6
If the input terminals of Pilot (Bit 2), RX1 (Bit 0) and 52b (Bit 5) with a rated voltage applied, the
display will show "OPTI 25", e.g., it is equivalent to a binary number of 00100101. See Section
1.1.1.14, page A-16).
4.6 JUMPER CONTROLS
The following jumpers are set at the factory; the customer normally does not need to move the
jumpers. Refer to Table 4-4 (page 4-22) for the recommended jumper positions.
4.6.1 Backplane Module
An external jumper should be wired to the right side 2FT-14 switch #13 (term. #2) and #14 (term
#4). See Figure 4-3.
When FT switch #13 or #14 is opened, the BFI and RI output relays are disabled to prevent BFI
and RI contact closures during system function test.
4.6.2 Interconnect Module
The factory sets jumpers (JMP1 through JMP6 and JMP13) for 48 Vdc or 125 Vdc input source.
JMP7 & 9 are used for Stub Bus Protection (SBP). If SBP is not used, move JMP7 & 9 to 8 &
10 position for the second set of AL2-2 use.
NOTE: If the customer intends to use a voltage other than 48 Vdc or 125 Vdc, check jumper
position on Interconnect module.
4.6.3 Microprocessor Module
The following jumpers are normally set during factory calibration:
• JMP1, JMP8,
JMP9
• JMP2
• JMP3
• JMP4
Channel receive contact closure input #1, RX1
Channel receive contact closure input #2, RX2
Pilot enable contact closure input, PILOT
Stub bus contact closure input, SBP
52a contact closure input, 52
52b contact closure input, 52b
External reset contact closure, EXTRST
for EEPROM and RAM circuitries, and are normally set to
position 1-2. JMP 1, 8, 9 are removed for Module Sub 5 and higher.
normally set to position 1-2 for three pole trip or programmable
output contact logic. Set position 2-3 for single-pole trip logic
only.
Phase rotation; "OUT" for ABC, "IN" for ACB
set to "IN" for trip contact with dropout time delay.
