Alarm circuit is not used for SR versions.
AC Power—Connect a grounding wire to the grounding screw provided in
the switch. This is important for safety as well as noise. Power only with the
AC voltage level indicated on the inner cover label. Orientation of AC power
to terminals 1 and 2 is not important.
Shutdown Circuit—The internal shutdown switch circuit is designed to be
wired in series with the external shutdown circuit i.e.; motor starter, relay,
contactor, etc.
Remote Reset—Shielded wire is required. To avoid creating ground loops,
the N.C. remote switch contacts should be electrically isolated from other
circuits or grounds.
Remote reset is disabled if push-button reset option is selected.
Lockout (Optional)—Terminal 7 will be labeled “Lockout”. Shielded wire is
recommended. To avoid the possibility of ground loops, the remote N.O.
lockout switch contacts should be electrically isolated from other external
circuitry or grounds.
4-20 mA Analog Output—To avoid the possibility of ground loops, the 4-20
mA remote meter terminals should be electrically isolated from external grounds.
Shielded wire is recommended to protect against damage due to long wire runs
and the possibility of high induced voltage spikes from storms, etc. The 4-20
mA output is self-powered and therefore requires no external power source.
Alarm Circuits—The internal single pole solid state switch between terminals
13 and 14 is designed to be wired in series with the external alarm circuit e.g.;
annunciator, lamp, relay, etc.
