BE1-CDS220 Testing And Maintenance 13-63
Logic Timer Verification (62/162)
Mode 1 - Pickup/Dropout
Purpose : To verify the operation of the 62 timer elements.
Reference Commands : SL-62/162, S<g>-62/162
Step 1. Prepare for mode 1 logic timer verification testing by sending the commands in Table 13-69 to
the relay.
Table 13-69. 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_INITIATE,PU,DO Name switch to make SER easier to read
SL-62=1,43 Enables 62 PU/DO mode, 43 initiate, no block
S# -62=400m,2000m Sets 62 pickup = 400 ms, dropout = 2,000 ms
EXIT Exit
Y Save settings
Step 2. Send the commands in Table 13-70 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.
Table 13-70. x62 Mode 1 Timer Initiate Commands
Command Purpose
A= Gain write access
CS-43=1 Selects 43 for close operation
CO-43=1 Executes 43 for close operation
Step 3. Send the commands in Table 13-71 to the relay. These commands will remove the initiate
input from the 62 timer by changing the 43 switch state to open (logic 0). It is not necessary to
gain access for the following steps unless access times out.
Table 13-71. x62 Mode 1 Timer Initiate Clear Commands
Command Purpose
CS-43=0 Selects 43 for open operation
CO-43=0 Executes 43 for open operation
Step 4. Use the RS-LGC command to retrieve logic variable data from the SER. Verify that the 43
switch change to a closed state, was logged, and approximately 400 milliseconds later, the 62
timer picked up. Then, some time later, the 43 switch changed to an open state, was logged,
and the 62 timer dropped out approximately 2,000 milliseconds later. The state of the 43
switches in the SER report use the programmable name parameters applied to the switch.
Figure 13-17 illustrates the timing relationship of the 43 switch and 62 timer.
