Step 4 Apply and remove positive or polarity PSV to Input1, terminal B1. Verity that OUT1 closes and
remains closed.
Step 5
Power down the relay and verify that OUT1 opens. Wait 10 seconds and power up the relay. Verify
that OUT1 closes. This verifies that 86 position is stored in non-volatile memory.
Step 6 Apply and remove positive or polarity PSV to Input2, terminal B3. Verity that OUT1 opens and
remains open.
Step 7 Repeat steps 1 through 6 for the 186 virtual lockout.
Logic Timer
Purpose: To verify the operation of the 62/162 timer elements.
Reference Commands: SL-62/162, S<g>-62/162, RS-LGC
NOTE
In these tests, the relay's virtual switches (x43) are used to initiate the 62/162 timers. See
Section 4,
Protection and Control, Virtual Switches for detailed information about x43 switch
operation.
Mode 1 - Pickup/Dropout
Step 1
Prepare the 62 timer for Mode 1 testing by transmitting the commands in Table 13-88 to the relay.
Table 13-88. x62 Mode 1 Test Commands
Command
Purpose
A=
Gain write access
SL-N=NONE
Zero out custom logic settings. Overwrite with
logic=none settings.
Y
Confirm overwrite
SL-N=T62
Sets T62 as custom logic name
SL-43=2
Enables 43 switch ON/OFF mode
SN-43=62_INI,PU,DO
Name switch to make SER report easier to read.
SL-62=1,43
Enables 62 PU/DO mode, 43 initiate, no blocking
EXIT;Y
Exit and save settings.
Step 2 Transmit the commands in Table 13-89 to set the 62 function pickup and dropout time.
Table 13-89. x62 Mode 1 Pickup and Dropout Settings
Command
Purpose
A=
Gain write access
S#-62=400m,2000m
Sets 62 pickup at 400 milliseconds,
dropout at 2,000 milliseconds
EXIT;Y
Exit and save settings.
Step 3 Transmit the commands in Table 13-90 to the relay. These commands will initiate the 62 timer by
changing the 43 switch state to closed (logic 1). Once initiated, the 62 timer will force an output
based on the 400 millisecond pickup time setting.
