Step 6 Use the procedure outlined under "Acceptance Tests, Control Outputs" to actuate selected
output contacts (V01 through V05), and actually trip or close the connected field device (circuit
breaker, lockout, etc.). Use the same procedure to verify that operation of the alarm output relay
(V0A) initiates the appropriate alarm response.
Virtual Selector Switches (If not used, skip to Virtual Control Switch)
Purpose: To verify the operation, labels, and logic settings of the 43 switches.
Reference Commands: SN-43, SL-43, RG-43STAT, RG-STAT, CS/CO-43
Step 1 Transmit the SN-43 command to verify the virtual selector switch 43 name, TRUE label, and
FALSE label. This information is reported using the format SN-x43=name,TRUE label,FALSE
label.
Step 2 Repeat Step 1 for virtual selector switches 143 through 743. Use the number of a switch in the
SN-43 command to retrieve name and label information for that switch.
Step 3 Use the SL-x43 command to obtain the logic setting of virtual switches 43 through 743. Logic
settings for virtual switches can also be obtained by using the SL command or by viewing
optional HMI screens \CTRL\43\43 through \CTRL\43\743. Verify that the desired virtual selector
switch setting matches the reported setting.
Step 4 Transmit the RG-43STAT command to obtain the position of the eight virtual selector switches.
Alternately, the virtual selector switch positions can be obtained through the RG-STAT command
or optional HMI screens \CTRL\43\43 through \CTRL\43\743.
Step 5 Obtain write access to the relay by using the ACCESS= command. For each virtual selector
switch enabled in your logic scheme, change the switch position by entering CS-x43 = 1 (TRUE),
0 (FALSE), or P (Pulse) followed by CO-x43=1,0, or P. The syntax of the CS-x43 and CO-x43
commands must match or the CO-x43 command won't be executed.
Step 6 Verify each switch position change by using the CO-x43 command or through optional HMI
screens \CTRL\43\43 through \CTRL\43\743.
Step 7 Return each virtual selector switch to the original position by repeating Step 7.
Step 8 Verify the 43 switch activity by viewing the sequence of events reports with the RS-###
command.
Virtual Control Switch (If not used, skip to Protection and Control Function Verification)
Purpose: To verify the operation, label, and logic setting for the 101 switch.
Reference Commands: SB-LOGIC, SL-101, RG-101STAT, RG-STAT, CS/CO-101
Step 1 Verify the breaker label and breaker-closed logic expression with the SB-LOGIC command.
Step 2 Use the SL-101 command to read the logic mode of the 101 switch. The switch is either
enabled (1) or disabled (0).
Step 3 Obtain the virtual control switch status by using the RG-101STAT or RG-STAT commands.
Step 4 Transmit the command ACCESS= to obtain write access to the relay. Change the switch
position by entering CS-101=T (Trip) or C (Close) followed by CO-101=T (Trip) or C (Close).
The syntax of the CS-101 and CO-101 commands must match or the CO-101 command won't
be executed.
Step 5 Confirm the switch position change with the RG-101STAT or RG-STAT commands.
Step 6 Repeat Step 4 to return the 101 switch to the desired position for your application.
Step 7 Verify the 101 switch activity by viewing the sequence of events reports with the RS-###
command.
Protection and Control Function Verification
Before placing the relay in service, the user should ensure that all system ac and dc connections are correct,
that the relay functions as intended with user settings applied, and that all equipment external to the relay
operates as intended. All connected or monitored inputs and outputs, and polarity and phase rotation of ac
connections should be tested. Verify that:
