despite a second 143 FALSE to TRUE initiate signal while the duration timer was active. Figure
13-4 illustrates the timing relationship of the 143 switch and x62 timer.
Mode 3 - One-Shot Retriggerable
Step 1 Prepare the 62 timer for Mode 3 testing by transmitting the commands in Table 13-94.
Table 13-94. x62 Mode 3 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-62=3,343,0
Enables 62 1-shot, retriggerable mode, 343 initiate, no blocking
SL-343=3
Enables 343 switch momentary Pulse mode
SN-343=62_INI,INI,NORMAL
Name switch 343 to make SER easier to read.
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.
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.
