SC200 System Controller
The SC200 system controller is an advanced control and monitoring solution which provides a
full suite of communications options, including built-in Ethernet interface, Web server, and
SNMP agent.
Alarm notifications may be by SNMP traps, SMS text messaging, dial-out to PowerManagerII
remote monitoring software, or relay contact closures.

The SC200 is supplied pre-configured with either a default configuration file, or with one
factory customized for a particular application. Some configuration file changes can be made
with the keypad, or all settings can be changed via a PC connected to the USB interface (see
details on page 17).
For connector pin-outs see details on page 101. See Troubleshooting on page 88 for details of
SC200 alarm LEDs.
Input/Output Board
The input/output (I/O) board provides the I/O interfaces and connections for the SC200
system controller.
The I/O board includes a range of sense inputs for dc power system control and monitoring. It
also allows real time data collection from building services and other external devices, and relay
outputs for alarm signals or control of external devices.

Battery Test
Battery Test is a preventative maintenance tool that monitors the discharge capabilities to
ensure that the condition of the battery has not deteriorated over time.
The SC200 temporarily reduces the output voltage of the rectifiers to just below the bus voltage
for a set duration. The battery then supplies power to the load. A battery test passes if the
battery voltage remains above a predetermined level for the duration of the test.
Battery Tests can be scheduled to occur at regular intervals, and/or can be started/stopped
manually, and/or can be started by an external relay contact or switch.

Battery Test does NOT function during a Fast Charge or Equalize, or during the lock-out period
after an ac supply failure.

System Operation
Load Based Rectifier Shutdown

Load Based Rectifier Shutdown is not available with APR48-3G, EPR48-3G, APR24-3G and
CR48-3G rectifiers.
If Load Based Rectifier Shutdown (LBRS) is enabled then the SC200 automatically shuts down
rectifiers when the total load current is significantly less than the total rectifier capacity.
This raises the average load on the remaining rectifiers which will then operate at a higher
efficiency. This results in a decrease in system power consumption.
The run time of all rectifiers is recorded and balanced to ensure even aging.
The SC200 will progressively restart rectifiers if the load increases.


Rectifiers shut down by LBRS will have the yellow LED on.

The SC200 will automatically restart all rectifiers if ac supply has failed, or more than one rectifier
has failed, or the bus voltage is below the Low Load threshold, or Battery Test / Equalize / Fast
Charge are active.
At least two rectifiers will always be on to maintain N+1 rectifier redundancy. Therefore, LBRS
has no effect in dc power systems with only one or two rectifiers.
► To enable Load Based Rectifier Shutdown

Use the SC200 keypad to go to: Control Processes > Load Based Rectifier Shutdown.


Or, in DCTools/Web go to: Rectifiers > Load Based Rectifier Shutdown
Ensure that Rectifier Start Up Delay is less than 30 seconds. See information on page 29. LBRS
will not function correctly if the start up delay is more than 30 seconds.

Low Voltage Disconnect (LVD)
Low Voltage Disconnects may be connected either as load disconnect or battery disconnect
depending on the dc power system model. They have two purposes:

to protect a VRLA battery from deep discharge and premature failure, and/or

to reduce the load on a battery under discharge so that high priority equipment operates
for a longer time after an ac supply failure.
The SC200 has 16 independent LVD control channels (LVD 1 to LVD 16). Each channel can
control one or more of up to 16 contactors, with coil voltages from 12V to 48V nominal.

There are two contactor connectors on an IOBGP input/output board. Additional contactors are
controlled by additional IOBGP-01 input/output boards. If required, refer to the dc power system
Installation and Operation Guide for details on how to connect additional IOBGP-01 input/output
boards to the SC200.
LVD Disconnect Modes
The LVD control channels can have any combination of the following modes of operation:
1
Voltage Based Disconnect: The LVD control channel will disconnect its contactor(s) based
on the bus voltage.
2
AC Timer Based Disconnect: The LVD control channel will disconnect its contactor(s) after
a specified period of ac supply failure.
3
Smart Alarm Disconnect: The LVD control channel will disconnect its contactor(s)
according to the state of a specified Smart Alarm. See Smart Alarm Disconnect on page 38.

32
CAUTION: An unnecessary LVD disconnection may occur if the Smart Alarm uses a sensor
or other input device which becomes faulty or disconnected.

System Operation
If Chained to Previous is enabled, the LVD control channel will only disconnect its contactor(s) if
one of its disconnect conditions is True, and the preceding control channel has been
disconnected for the Recognition Time.

Chained to Previous does not apply to LVD 1.
LVD Default and Custom Configuration
If factory-fitted in the dc power system, the LVD contactors will be characterized and the LVD
control channels will have default configuration settings for Voltage Based Disconnect. Custom
configuration will only be necessary if:

contactors are connected to the dc power system on site (see LVD Characterization on page
34 and LVD Setup on page 35)

different disconnect conditions are required (see LVD Configuration on page 37).
Typical LVD Arrangements
The simplest use of an LVD is a single battery disconnect contactor.
The following diagram shows a typical arrangement of two LVDs. This arrangement allows
lower priority loads to be disconnected first (contactor controlled by control channel LVD 1),
either at a specified battery voltage or a specified time interval after an ac supply failure. This
then prolongs battery power for the highest priority loads (contactor controlled by control
channel LVD 2). The battery will be disconnected when the battery voltage reaches its
minimum preset voltage.

Contactor controlled by
LVD 1 - low priority load

first).

Contactor controlled by
LVD 2 - battery

disconnects after LVD 1)

Connections to high
priority loads (for example
transmission equipment).

Connections to low


Connection to the SC200
system controller via the
I/O board.
More complex arrangements with up to 16 contactors and a selection of disconnection criteria,
are possible with the SC200 system controller. The exact arrangement(s) used in a particular
Eaton dc power system will be described in the Installation and Operation Guide.

Characterization
If auxiliary contacts are fitted to the LVD contactor(s)*, then the LVD Characterization process
determines the optimum operating voltages to suit the contactor(s) coil voltage. These values
are stored in the SC200 and on the I/O board.
An LVD Characterization Error alarm will be activated if the SC200 detects that the
characterization values stored in the SC200 and on the I/O board are different. This happens
when:

The SC200 is replaced. To clear the alarm, on the SC200 select Use IOB Values.

The I/O Board is replaced. To clear the alarm, on the SC200 select Use SC Values.

Both the SC200 and the I/O Board are replaced. In this case, re-characterize the
contactor(s).

When a contactor is re-characterized it will disconnect and re-connect several times. Refer to
Maintenance in the dc power system Installation and Operation Guide for full instructions.
Factory-fitted contactors will be characterized at the factory. If an existing contactor is replaced,
characterize the new contactor from the SC200.

In this case, there will be no LVD Characterization Error alarm.

Smart Alarms
Smart Alarms are a software simulation of logic gates to allow the logical combination of other
alarms, time schedules and/or system values. Up to 32 Smart Alarms can be configured.
A single Smart Alarm is the equivalent of a multi-input AND, OR or XOR logic gate. More
complex logic arrangements are created by using one Smart Alarm as an input into another. For
example:
Two input AND gate:
SAx = Sa AND Sb
Three input OR gate:
SAy = Sa OR Sb OR Sc
Multi-gate logic:
SAz = SAx OR NOT Sd

One input is Smart Alarm SAx (output
from another gate). The other input is
negated. This is available with Alarm
Sources only.
Key:
SAx, SAy, SAz are Smart Alarms (entered in the Smart Alarms table).
Sa, Sb, Sc, Sd are the Sources (entered in the Alarm Sources, Schedule Sources or System Value

Battery Mid-point Monitoring (MPM)
Battery Mid-point Monitoring provides a cost-effective method for the early detection of
internal battery faults. The voltages of the two halves of a battery string are measured and the
system controller generates an alarm signal if a voltage imbalance is detected.
A voltage imbalance is an indication that one or more cells has an internal fault. Further
investigation can then isolate the faulty cell(s) and action can be taken to correct the problem
and prevent a total battery failure.
To connect Battery Mid-point Monitoring see details in the dc power system installation guide.
If a String Fail alarm is generated see Troubleshooting on page 88.
To ensure reliable operation Mid-point Monitoring operates only when the battery is in float
charge and after a configurable lockout period since the last battery discharge, Fast Charge,
Equalize or Battery Test.

After the end of a discharge, Fast Charge or Equalize cycle, MPM does not start until the
end of the MPM Lockout Period, to ensure the system is in float charge.
2
At this point, the battery cell voltages are expected to be widely spread, so the alarm

Battery Time Remaining
The SC200 obtains characterization data from every full battery discharge, to a specified end
voltage.
During a battery discharge, the SC200 uses this characterization data to calculate an estimated
time until the battery will reach the specified end voltage.

If a battery disconnect LVD is fitted then the end voltage will usually be the voltage at which the
LVD disconnects the battery.

Battery Time Remaining is designed for a constant power load. The accuracy of the time
remaining calculation will be reduced if the dc power system is connected to a predominantly
resistive (constant current) load.

The time remaining calculation will not be correct if a non-essential load is disconnected during
the battery discharge.

It will take at least 10 hours to characterize a battery.

When a battery is characterized it is discharged. The bus voltage will gradually
reduce to the battery end voltage. Ensure that this will not affect the operation of
any equipment connected to the dc power system.
Use the following procedure to configure Battery Time Remaining for the first time, or if a
previously characterized battery is changed.

Battery Characterization is not necessary if a previously saved battery characterization data file is
available. Refer to Characterization Data Management on page 58. Only use characterization data
for an identical type and size of battery.
► To configure Battery Time Remaining

Generator Control Option
Generator Control is used to delay the start of standby ac generators until the batteries are
partially discharged (rather than immediately after the ac supply fails). This can save fuel by
preventing generators running during short ac supply failures. It can also be used to control a
generator in a hybrid power system (cyclic charge/discharge).
Generator Control uses a digital output (relay) which is connected in series with the generator
run signal of the generator controller. The relay is controlled by the Generator Enable alarm. The
relay contacts interrupt the generator run signal until the Generator Enable alarm is active.
The Generator Enable alarm is activated when the ac supply fails and either the Fast Charge or
Equalize control process starts (depending on the setting of the Generator Start Trigger).
The Generator Enable alarm stays active (and the generator running) until the ampere-hours
recharged is enough for the battery to be fully charged, or until the maximum fast charge
duration is reached.
A Generator Fail alarm is activated if the SC200 does not detect that the ac supply is present
(rectifiers have turned on) after the Generator Fail Alarm Recognition Period following Generator
Enable becoming active.

E
The SC200 uses mappings to allow it to associate internal functions, alarms and physical I/O
devices.

A default mapping is set at the factory before delivery. Usually this default mapping will not need
to be changed.
I/O Board Mapping
The serial numbers of an I/O board and SiteSure-3G modules, and the physical connectors on
the board/modules are mapped to logical numbers in the SC200. This allows the physical
inputs and outputs (including LVD contactors) to be recognized by the SC200.
I/O Board serial number mapping
Each I/O board serial number must be mapped to a logical IOB Number.
Usually, I/O board serial number mappings only need to be changed if:

The I/O board is changed or added. See details on page 92.

The SC200 is changed and/or a new configuration file is loaded into the SC200. See details
on page 92.

This mapping is not included in configuration files and must be set if an SC200 is changed or
loaded with a new configuration file. Input/output, sensors and most voltage control processes are
only available if this mapping is set.
► To map I/O boards
Either:

Use the SC200 keypad to go to: Settings > IOBs. The serial numbers of registered
input/output boards are displayed.

Select an unmapped Input/Output board (identified as New). Press Enter. Identity
information is displayed and the I/O board LED will flash.

Press Map and select an unused IOB Number (or one marked as Missing, if replacing an
I/O board). Press Enter.
Or:

In DCTools/Web go to: Configuration > RXP

Copy the I/O board serial number(s) from the RXP Devices table to the I/O Board to Serial
Number Mapping table to map an IOB Number to each I/O board (overwrite an existing
serial number if required).

If multiple SiteSure-3G modules are installed use the I/O board Identify function to physically
identify each board. See details on page 62.

I/O connector mapping
Each I/O connector (analog input, digital input and digital output) on an I/O board must be
mapped to a logical IOB Number and IOB AI, IOB DI or IOB DO Number.
► To map I/O connectors
See Analog Inputs on page 63, Digital Inputs on page 66 and Digital Outputs on page 67.
