Note:
UNIPOWER, LLC CEMF Cells do not typically provide an alarm output. They do
provide a fuse alarm that can be connected to the spare fuse (
SP
) alarm input to
provide some measure of direct monitoring if desired.
2.6.4.2
Fuse Alarm inputs require a battery input. Five Fuse alarm inputs are provided to
divide these alarms into charge (
CH
), discharge (
DIS
), battery (
BAT
), sense/control
(
S/C
), and a spare input (
SP
) that can be used as desired (see 2.6.4.1). Refer to the
Datasheet for the required connections. Route and terminate these connections
carefully due to their battery potential when alarmed.
Note:
Plant Ground (
PGND
) and (
GRD
) must be connected to the grounded terminal of the
batteries for the fuse alarms to function properly. See PN drawing for typical
connections.
2.6.4.3
The Low Voltage Disconnect alarm input requires a ground closure input. Verify the
LVD to be monitored can provide this type of output before proceeding. The alarm
lead is connected to the
(
LVD
) input terminal. Refer to the Datasheet for the
required connections.
2.6.4.4
The Rectifier Fail alarm inputs require a ground closure input. Verify the Rectifiers
to be monitored can provide this type of output before proceeding. The SAGEON
PSMC I can monitor up to 16 individual Rectifier fail alarm leads that are connected
in sequence to the
(
RFA
) input terminals. Refer to the Datasheet for the required
connections. Make sure the Datasheet clearly shows which rectifier is connected to
each input.
2.6.4.5
The Control Inhibit (
INH
) input requires a ground closure input. The Control Inhibit
(
INH
) input relinquishes control functions from the SAGEON PSMC I. When
triggered the Control Inhibit will disable the Rectifier ReStart (
RS
), Equalize (
EQ
),
and High Voltage Shut Down (
HVSD
) control output relays. The SAGEON PSMC I
will continue to monitor all input channels and provide alarm condition relay outputs
when Control Inhibit is active. See section 2.6.5 for information about the control
relays.
This completes the Binary input connections. Stop and verify these connections and update the
Datasheet if necessary. See Enabling Channels section after the installation wiring is complete.
2.6.5 Control Relays
The SAGEON PSMC I provides three rectifier control outputs: Equalize (
EQ
), High Voltage
Shutdown (
HVSD
), and Restart (
RS
). These Form A, normally open, relay outputs share a
common control connection to
CTRL RET
. This connection must be tied to the appropriate
potential, either plant ground or battery. Most applications will require a ground closure. In
either case, all three outputs MUST utilize the same common output potential or the user
must decide which outputs he can use appropriately.
2.6.5.1
The Equalize (
EQ
) output provides an operator initiated manual timer or a voltage
initiated automatic timer. 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
EQ
output. See Fig. 6 of PN
drawing and Setting Up Equalize section in this manual.
