power cord.
21. Ground Terminal Connect Ground terminal to the earth ground.
22. Remote I/O Control Remote I/O output joint point:
Test signal: Two test holes has to be shorted when
getting into test mode by pressing Start
key, and it won’t return to open status
until the test result of PASS or FAIL
comes available, or the RESET key is
pressed.
PASS signal: At the time when the test result comes
out to be PASS, two PASS holes has to
be shorted, and return to open until the
RESET key is pressed.
FAIL signal: At the time when the test result comes
out to be FAIL, two FAIL holes has to
be shorted, and return to open until the
RESET key is pressed.
RESET: The function is same as the RESET key on
the front panel.
START: The function is same as the START key on
the front panel.
23. Current Monitor The cutoff current can be directly monitored by
disconnecting the shorting bar from these terminals
and connecting a milliammeter (DC/AC) between
them. The milliammeter should be capable of
measuring the cutoff current. Be sure to connect the
shorting bar when no milliammeter is connected
between these terminals.
