Step 4: Repeat Steps 2 and 3 for all of the current and time dial settings for your current sensing type.
Step 5: (Optional.) Repeat Steps 2 through 4 for phase B (Terminals D3 and D4) and phase C
(Terminals D5 and D6).
Step 6: (Optional.) Using ASCII commands, substitute 151 for any 51 logic or setting commands in each
test.
Pickup and Dropout Verification
Purpose: To verify the pickup accuracy of the 51P, 51N, 151P, 151N, and 51Q elements.
Reference Commands: SL-51P, SL-151P, SL-51N, SL-51Q, SL-151N, SL-GROUP, SL-VO
Step 1: Connect a current source to Terminals D1 and D2 (A-phase). Refer to Figure 12-3 for
terminal locations. An ohmmeter or continuity tester may be used to monitor output contact
status.
Step 2: To prepare the 51P, 51N, and 51Q elements for testing, transmit the commands in Table 13-26
to the relay. Reset targets.
Table 13-26. 51P/51N/51Q Pickup Test Commands
Command Purpose
A= Gains write access.
SL-N=NONE
Zero out custom logic settings. Overwrite with LOGIC=NONE
settings.
Y Confirm overwrite.
SL-N=PU51 Sets PU51 as custom logic name.
SL-51P=1,0 Enables 51P and disables blocking.
SL-51N=1,0 Enables 51N and disables blocking.
SL-51Q=1,0 Enables 51Q and disables blocking.
