N otee: Setting the S2 switch of the MET Tester to the
"CALIBRATE" position for more than three seconds
[with the MET Tester in the OPEN state] will
cause the Interrupter Malfunction diagnostic to
become active. The control CLOSED and LOCKOUT
LEDs will alternately blink with the OPEN LED. If
the Interrupter Malfunction alarm is configured,
the ALARM LED will also blink. The Interrupter
Malfunction diagnostic state is kept in non-volatile
memory, so it is not cleared when the control
is rebooted. In order to reset the Interrupter
Malfunction diagnostic, go to Reset Targets under
the Counters menu and press the ENTER button two
times to reset targets.
N otee: When using the MET electronic recloser control
tester, cable part number KSPRC-145-15 must be
used with the SPEAR Single-Phase Recloser Control
to ensure proper testing and control operation.
