was switched on, and it does it at a very high speed. You can now
exit from Func. mode.
4) If you wish to avoid injecting an excessive amount of current acci-
dentally while regulating your test current, use the
Ilim
function as
described in Protecting Your Relay.
5) Do the same with the
Tlim
function entering the longest time for
which you know it is safe to sustain the above specified current limit
through your relay while you are regulating the test current. Do not
forget to press to effectively activate this one and the
Ilim
protection (LED should toggle from slow to fast blinking). The speci-
fied time should be longer than the expected instantaneous opera-
tion time.
6) After you exit the Func. mode, the LEDs next to these three functions
should be steadily lit. Otherwise, back up to Func. mode, navigate
to the function and press to toggle its LED to fast blinking.
7) Do NOT press now. Switch the output and try to
reach the instantaneous setting for the current before the
Tlim
pro-
tection operates and the output is suspended.
8) Retry step 7) until you achieve the desired value for the instantane-
ous test setting in Display #2.
9) Press to zero the timer out and to set the unit to suspend
the output automatically upon relay’s operation.
10) Press to start the test. The relay should operate before the
time specified for
Tlim
elapses, and the injection will be automati-
cally suspended. The resulting operation time and current will be
shown by displays #1 and #2 respectively.
11) Check the relay’s consistency by repeating steps 9) and 10) a
couple of times and write the results down.
12) Repeat steps 7 thru 11 for each current value that you need to test.
