2.6.5.2
The High Voltage Shutdown (
HVSD
) output provides a triggered output from the
user settable
HVSD
threshold. If this control feature is desired, determine if the
rectifiers support this function and what type of input is required. The
CTRL RET
terminals are common to one another and must be jumpered to the proper potential.
Multiple rectifiers can be daisy chained with a lead from the
HV
output. See Fig. 6
of PN drawing and Setting Up HVSD & Restart section in this manual.
2.6.5.3
The Restart (
RS
) output provides a triggered output from the user settable low voltage
LV
threshold. If this control feature is desired, determine if the rectifiers support this
function and what type of input is required. The
CTRL RET
terminals are common
to one another and must be jumpered to the proper potential. Multiple rectifiers can
be daisy chained with a lead from the
RS
output. See Fig. 6 of PN drawing and
Setting Up HVSD & Restart section in this manual.
This completes the Control Output connections. Stop and verify these connections and update the
Datasheet if necessary. See Setting Thresholds section after the installation wiring is complete.
2.6.6 Output Relays
The output relays all provide Form C relay contacts supporting normally open or normally
closed connections. Two sets of Major and Minor contacts are provided for separate remote
monitoring and local annunciation panels. The Major alarm relay is normally energized for
fail safe operation. All other relays are normally de-energized. An Auxiliary relay is user
programmable. See Programming the Auxiliary Relay section of this manual. The relays
requiring ground closures should have been jumpered to
PLANT GRD
at the beginning of
the wiring process based on the Datasheet requirements. Refer to the Datasheet and PN
drawing figures for assistance in wiring the output relays.
The SAGEON PSMC I also supports an internal audible alarm that can be user programmed
to trigger from various alarm outputs. Refer to Setting Up The Audible Alarm section of this
manual for programming instructions.
2.6.6.1
Verify ground closure jumpers to common (
C
) terminals on designated output relays
against Datasheet and modify connections if necessary. Ground closure relays
should be jumpered to PLANT GND and can be daisy chained as necessary.
2.6.6.2
The two
Major
output relays are normally energized. These outputs are triggered by
an
FA, VLVA, LVD, HVSD, WD, OC (over-current)
, or any two
RFA’s, TA,
CEMF, LVA or HV
alarms. Connections to powered annunciation panels should be
kept separate from remote alarm connections. Make the required connection to the
normally open (
NO
) or normally closed (
NC
) terminals as required. If necessary the
Aux relay can be configured as another Major output relay. Refer to the Datasheet
for required connections.
Note:
The labels for ALL output relays are provided in the de-energized state. e.g. The NO
labeled contact of the Major alarm relay will be closed during regular operation (no-
alarm/relay energized); likewise, the NC labeled contact of the Major alarm relay will
be open.
2.6.6.3
The two
Minor
output relays are normally de-energized. These outputs are triggered
by a single
RFA, CEMF, LV, HV,
or
TA
alarm. Connections to powered
annunciation panels should be kept separate from remote alarm connections. If
necessary, the Aux relay can be configured as another Minor output relay. Make the
