Command Purpose
S0-62=15s,20s Sets 62 delay at 15 seconds. Sets 62 dropout at 20 seconds.
EXIT;Y Exit and save settings.
Step 2: Transmit the commands of
Table 13-95 to the relay. These commands supply the 62 Timer with
a momentary initiate input by pulsing the 343 Switch from FALSE to TRUE and then back to
FALSE. You may view the state changes of the 343 Switch at Screen 1.5.4 of the front panel
HMI.
Table 13-95. x62 Mode 3 Timer Initiate Commands
Command Purpose
A= Gains write access.
CS-343=P Selects 343 for pulse F-T-F operation.
CO-343=P Executes 343 pulse F-T-F operation.
CS-343=P Selects 343 for pulse F-T-F operation.
CO-343=P Executes 343 pulse F-T-F operation.
Wait at least 15 seconds (but no longer than 35 seconds) to execute next commands.
CS-343=P Selects 343 for pulse F-T-F operation.
CO-343=P Executes 343 pulse F-T-F operation.
EXIT Exit select and operate mode.
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 13-7.
After a 343 FALSE-TRUE-FALSE pulse action was logged, the 62 Timer output did not go
TRUE because of a second FALSE to TRUE initiate signal action.
Approximately 15 seconds after the second 343 FALSE to TRUE initiate signal, the 62 Timer
output went TRUE. The timer output went FALSE when the third FALSE to TRUE initiate signal
forced the 62 Timer (T1) to restart.
Fifteen seconds after the third 343 FALSE to TRUE initiate signal, the 62 Timer output went
TRUE again and then went FALSE after the duration timer (T2) expired 20 seconds later.
NOTE
The 343 switch action is performed three times in this test. To illustrate the action
of the timer mode, the second 343 Switch action should be executed as quickly
as possible (within the 15 second duration of the pickup time delay). Perform the
third 343 Switch action after at least 15 seconds (the pickup timer setting) have
elapsed but before the 20-second dropout time delay expires. This will illustrate
the action of the timer mode. The time delay settings may be increased if
difficulty is encountered with repeating the 343 Switch actions.
