Fuse alarms are battery voltage inputs. Inline fuse protection is recommended if these
connections must utilize overhead cable runs. Determine best cable routing, connection
requirements and add this information to the Datasheet.
Note:
Do not use inline resistors for protection on fuse alarms as SAGEON PSMC I
internal sensing circuits will be adversely affected and may fail to register fuse
alarms; fuses must be used instead.
2.4.8 Two ground closure true inputs are provided for CEMF Cell alarm inputs (
CEMF1
&
CEMF2
). If a CEMF Cell is included verify it provides the proper input. No inline
protection is required for ground closure type inputs. Determine the best cable routing,
connection requirements and add this information to the Datasheet.
2.4.9 A ground closure true input is provided for a Low Voltage Disconnect (
LVD
) alarm. If a
Low Voltage Disconnect is included, verify it provides the proper input. No inline protection
is required for ground closure type inputs. Determine the best cable routing, connection
requirements, and add this information to the Datasheet.
2.4.10 If Ambient (
AMB
)
and battery temperature (
TS1
&
TS2
) sensors are included, determine the
mounting locations. The ambient sensor should be bolted to a large thermal mass, such as the
rack itself, to limit response to short term changes.
Two battery temperature sensor inputs are provided for up to two battery strings. Sensors are
designed with lead plated ring lugs to be connected with battery strap hardware. Sensor
detection circuits are isolated from battery potential. Sensors come with 30 ft. leads, which
can be extended with butt splices if necessary.
Cable runs in excess of 100 ft. may degrade temperature readings due to voltage drops. No
inline protection is required for temperature sensors. Determine best cable routing,
connection requirements and add this information to the Datasheet.
2.4.11 The alarm output relays are the last consideration. The user must determine the local
requirements such as the presence of a central alarm monitor or separate audible or visual
alarm panels. All the output relays are normally de-energized except the Major alarm, which
is energized for fail safe operation. All relays are rated at 60W, 62.5VA.
All alarm output relays are Form C, and can provide either normally open or normally closed
connections. Ground closure alarms can utilize the Plant Ground screw terminals for jumpers
to the common connection on the output relays. Determine best cable routing, connection
requirements, and add this information to the Datasheet.
2.5 INSTALLATION GUIDELINES
The following topics provide guidelines and suggestions to facilitate wiring the SAGEON PSMC I
in a fast and efficient manner, producing a quality installation that looks professional and limits
potential problems.
2.5.1 Sketch out the wire routing from the SAGEON PSMC I on paper to determine the best
routing that allows the maximum number of wires to be bundled together from the SAGEON
PSMC I to the furthermost possible connection point. Creating wiring bundles facilitates
routing and provides protection to individual wires.
