Figure 13-18. x62 Mode 2 (One-Shot Nonretriggerable) Timing Example
Mode 3 – One Shot Retriggerable
Step 1. Prepare for mode 3 logic timer verification testing by sending the commands in Table 13-74 to
the relay.
Table 13-74. 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-343=3 Enables 343 switch pulse mode
SN-343=62_INI,INI,NORMAL Name switch to make SER easier to read
SL-62=3,343,0 Enables 62 1-shot, re-triggerable mode, 343
initiate, no blocking
S0-62=15s,20s Sets 62 delay at 15 seconds, 62 dropout at 20
seconds
EXIT Exit
Y Save settings
Step 2. Send the commands in Table 13-75 to the relay. These commands supply the 62 timer with a
momentary initiate input by pulsing the 343 switch from a FALSE state to a TRUE state and
then back to a FALSE state. You may view the state changes of the 343 switch at front panel
interface \CTRL\43\343, screen 2.1.4.
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.
