13-68 Testing And Maintenance BE1-CDS220
Step 4. (Optional) Repeat the 62 timer tests for Modes 1, 2, 3, and 5 for setting groups 1, 2, and 3.
Mode 6 – Latch Timer
Step 1. Prepare for mode 6 logic timer verification testing by sending the commands in Table 13-78 to
the relay.
Table 13-78. x62 Mode 6 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=3 Enables 43 switch pulse mode
SL-143=3 Enables 143 switch pulse mode
SN-43=62_LATCH,INI,NORMAL Name switch to make SER easier to read
SN-143=62_RESET,RESET,NORMAL Name switch to make SER easier to read
SL-62=6,43,143 Enables 62 latch mode, 43 initiate, 143 block
(reset latch)
S0-62=30s Sets T1 at 30 seconds, T2 time not applicable
EXIT Exit
Y Save settings
Step 2. Sent the commands in Table 13-79 to the relay. These commands supply a latch input to the
62 timer by changing the 43 switch state to TRUE and a reset command by changing the BLK
input (143 switch) to TRUE.
NOTE
The CS and CO commands of Table 13-79 are performed two times. Follow the timing
sequence to illustrate timer mode action. The time delay settings may be increased if
difficulty is encountered with repeating the 43 and 143 switch actions.
Table 13-79. x62 Mode 6 Timer Initiate Commands
Command Purpose
A= Gain write access
CS-43=P Selects 43 for pulse operation
CO-43=P Executes 43 for pulse operation (initiates 62 timing)
Execute the following commands in less than 30 seconds
CS-43=P Selects 43 for pulse operation
CO-43=P Executes 43 for pulse operation (no effect)
Wait at least 30 seconds (total elapsed time) to initiate the latch reset (block) command (this
allows timer T1 to time out (output goes TRUE) and latch until the BLK input goes TRUE)
CS-143=P Selects 143 for pulse operation
CO-143=P Executes 143 for pulse operation (applies BLK input)
E Exit
Step 3. Use the RS-LGC command to obtain an SER report and verify that the following actions were
logged. These events are illustrated in the timing diagram of Figure 13-21.
Timer T1 continued to time out after the first 43 switch action (TRUE).
