SENS MicroGenius S2/S4 Technical Manual
1 IMPORTANT SAFETY INSTRUCTIONS FOR INSTALLER AND OPERATOR
1.1. SAVE THESE INSTRUCTIONS – This manual contains important safety and operating instructions for
MicroGenius
1.2. Before using battery charger, read all instructions and cautionary markings on battery charger, battery, and
product using battery.
1.3. Do not expose charger to rain or snow.
1.4. Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of
fire, electric shock, or injury to persons.
1.5. This charger is intended for commercial and industrial use. ONLY TRAINED AND QUALIFIED PERSONNEL
MAY INSTALL AND SERVICE THIS UNIT.
1.6. Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way;
shut off power at the branch circuit protectors and have the unit serviced or replaced by qualified
personnel.
1.7. To reduce risk of electric shock, disconnect the branch circuit feeding the charger before attempting any
maintenance or cleaning. Turning off controls will not reduce this risk.
® S2 and S4 battery chargers.
1.8. WARNING – RISK OF EXPLOSIVE GASES
1.8.1. WORKING IN THE VICINITY OF A LEAD-ACID OR NICKEL-CADMIUM BATTERY IS DANGEROUS.
STORAGE BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR
THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU READ THIS MANUAL AND FOLLOW THE
INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
1.8.2. To reduce the risk of battery explosion, follow these instructions and those published by the battery
manufacturer and the manufacturer of any equipment you intend to use in the vicinity of a battery.
Review cautionary markings on these products and on the engine.
1.9. PERSONAL PRECAUTIONS
1.9.1. Someone should be within range of your voice or close enough to come to your aid when you work
near a storage battery.
1.9.2. Have plenty of fresh water and soap nearby in case battery electrolyte contacts skin, clothing, or
eyes.
1.9.3. Wear complete eye protection and clothing protection. Avoid touching eyes while working near a
storage battery.
1.9.4. If battery electrolyte contacts skin or clothing, wash immediately with soap and water. If electrolyte
enters eye, immediately flood the eye with running cold water for at least 10 minutes and get
medical attention immediately.
1.9.5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
1.9.6. Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark or short
circuit the battery or another electrical part that may cause explosion. Using insulated tools reduces
this risk, but will not eliminate it.
1.9.7. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
storage battery. A storage battery can produce a short circuit current high enough to weld a ring or
the like to metal, causing a severe burn.
1.9.8. When charging batteries, charge 6 and 12 cell LEAD-ACID or 10 and 20 cell LIQUID ELECTROLYTE

SENS MicroGenius S2/S4 Technical Manual
NICKEL-CADMIUM batteries only, with rated capacity of 30 to 1100 Ampere hours. Charger
certified for fire pump and emergency generator applications. For a 24 hour recharge time do not
exceed 220 Ampere hours of capacity per 12A charger output current. Do not use this battery
charger to supply power to an extra-low voltage electrical system or to charge any type of nonrechargeable, dry cell, alkaline, lithium, nickel-metal-hydride, or sealed nickel-cadmium batteries
that are commonly used with home appliances. These batteries may burst and cause injuries to
persons and damage to property.
1.9.9. NEVER charge a frozen battery.
1.9.10. The charger contains a DC output fuse for internal fault protection, but this will not protect the DC
wiring from fault currents available from the battery. Consult national and local ordinances to
determine if additional battery fault protection is necessary in your installation.
1.10. Preparing Battery For Charge
1.10.1. Be sure area around battery is well ventilated while battery is being charged.
1.10.2. Ensure battery terminals are clean and properly tightened. Be careful to keep corrosion from
coming in contact with eyes.
1.10.3. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer.
Do not overfill. For a battery without removable cell caps, such as valve regulated lead acid
batteries, carefully follow manufacturer’s recharging instructions.
1.10.4. Study all battery manufacturer specific precautions such as removing or not removing cell caps
while charging and recommended rate of charge. The recommended charge current range must
include the rated output current of the charger.
1.11. Charger Location
1.11.1. Locate the charger as far away from the battery as DC cables permit.
1.11.2. Never place the charger directly above or below the battery being charged; gases from the battery
will corrode and damage charger.
1.11.3. Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling
battery.
1.11.4. Do not operate charger in a closed-in area or restrict ventilation in any way.
1.11.5. Do not set anything on top of the charger.

The above lengths consider the resistance of the battery and cables only and do not take into account any
additional interconnects. The above lengths are for operation at 25°C/77°F. For high temperature installations
(40°C/104°F) increase wire gauge by 10%.
6.2. Grounding Instructions and Connection
6.2.1. Charger must be grounded to reduce risk of electric shock. The charger must be connected to a
grounded, metal, permanent wiring system, or an equipment-grounding conductor (earthing
conductor) must be run with the circuit conductors and connected to equipment-grounding
terminal on charger.
6.2.2. Connect the equipment grounding conductor to the ground lug in the charger (see Figures 1-3).
This lug is marked with the ground symbol. This should always be the first wire connected and the
last wire disconnected.
6.3. DC Connection
Ensure that any battery disconnect devices in the system, if used, are opened (batteries disconnected
from DC bus). Connect the DC output conductors to the DC output terminal block/breaker in the charger
(see Figures 1-3). Chargers with multiple outputs share a common negative connection (see Figure 4).
Always observe proper polarity of the DC output leads. Always connect the output leads in the following
order – charger output to ungrounded battery terminal, followed by charger output to grounded battery
terminal. If the battery must be disconnected for service, remove the output wiring in the reverse order.
Tighten connections to torque specified in Table 3. Route DC wiring at least ¼ inch (6 mm) away from AC
wiring, alarm wiring, and the circuit board.

6.6. Remote Temperature Sensor Connection—Optional
The charger includes local temperature compensation using internal on-board sensors. Alternately, the
charger will use remote temperature compensation based on the temperature of the batteries when an
optional external sensor is located at the batteries and connected to the remote temperature sensor
terminal block in the charger (see Figures 1-3). Chargers with multiple output terminals also include
multiple remote temperature sensor terminal blocks (connect one sensor for each output). Remote
temperature compensation is highly recommended in all applications and is required for ultracapacitor
charging. It is most critical in applications where battery and charger are located in different ambient
conditions and in NFPA-20 fire pump and NFPA-110 emergency power system installations in order to
return 100% of the battery’s ampere-hour rating within 24 hours without causing damage to the battery.
The remote temperature sensor is not polarized; it does not matter which lead connects to each
terminal. Route sensor wiring at least ¼ inch (6 mm) away from DC wiring, AC wiring, and the circuit
board. Locate the remote sensor where it will accurately detect the battery temperature by connecting it
19
to a grounded battery terminal or the battery case. When securing to the battery case, use an

Temperature compensation is disabled by connecting a short across the remote temperature sensor
terminal block or by setting the temperature compensation slope to zero using the keypad or SENS Setup
Utility. See section 9.12
for further information regarding temperature compensation. A 50-foot remote
temperature sensor is available to order separately (SENS p/n 209481).
6.7. SAE J1939 Communications Setup (CANbus)
Every charger includes SAE J1939 (CANbus) communications. The J1939 interface provides a highly
reliable, low cost method of delivering to the genset controller all information that NFPA 110 requires
the battery charger to deliver. To be operational, the genset controller must support the charger J1939
connection. Contact your genset supplier to determine if your genset supports a J1939-connected
charger. See section 10
for further information on J1939 operation and registers.
J1939 communications are disabled by default and until the BCH address is configured (see section
6.7.1). Connect J1939 communications using a twisted pair cable at the RJ-45 connector on the
alarm/communications circuit board located on the inside front cover (see Figures 1-3 for location in
charger and Figure 7 for detail). Two RJ-45 ports are provided. The ports are in parallel and either port
may be used. See Table 10 for connector pinout. Communications are non-isolated and referenced to
negative battery terminal. An adapter from RJ-45 to an 8-position terminal block may be connected to
the RJ-45 connector and is available to order separately (SENS p/n 208026).

Table 10 – Connector Pinout
*Main circuit PCA only, used for interconnect between SENS devices
6.7.1. Battery Charger (BCH) J1939 Address
Configure the J1939 address using the front panel keypad (J9139 communications are disabled
until this address is configured). J1939 supports two chargers per network cable. Set to address 1
for main charger or address 2 for auxiliary charger. The charger is set to address 1 by default.
For multiple output chargers, J1939 address 1 (main charger) is assigned to charger output A and
address 2 (auxiliary charger) is assigned to output B by default. Use the keypad or the SENS Setup
Utility to configure J1939 addresses to any desired charger output.
6.7.2. Termination
For proper J1939 operation, a 120-ohm terminator is required at the ends of the J1939 bus. If
multiple devices are on the bus, only the devices on the ends of the network bus need
20
termination resistors. Figure 9 shows an example of how to terminate the network. The charger is
not equipped with terminators. Termination may be provided as part of the network cabling or
120-ohm termination plugs for the RJ-45 communications connector on the charger are available
to order separately (SENS p/n 803707).
6.8. Modbus Communications Setup
Every charger includes Modbus communications over RS-485 using RTU or ASCII mode. Modbus over
TCP/IP is optional. Modbus is an application layer messaging protocol used for client/server
communication and is implemented according to specifications provided by Modbus Organization
(http://www.modbus.org/specs.php). See section 11
configuration.
6.8.1. Modbus RS-485
Connect RS-485 Modbus communications using a twisted pair cable at the RJ-45 connector on the
alarm/communications circuit board located on the inside front cover (see Figures 1-3 for location
in charger and Figure 7 for detail). Two RJ-45 ports are provided. The ports are in parallel and
either port may be used. See Table 10 for connector pinout. Communications are non-isolated
and referenced to negative battery terminal. An adapter from RJ-45 to an 8-position terminal
block may be connected to the RJ-45 connector and is available to order separately (SENS p/n
208026). Modbus communications settings may be configured using the keypad or SENS Setup
Utility prior to initiating.
SENS MicroGenius S2/S4 Technical Manual

for further information on Modbus operation and
6.8.1.1. Termination
For proper Modbus RS-485 operation, a 120-ohm terminator is required at the ends of the RS-485
bus. If multiple devices are on the bus, only the devices on the ends of the network bus need
termination resistors. Figure 10 shows an example of how to terminate the network. The charger
is not equipped with terminators. Termination may be provided as part of the network cabling or
120-ohm termination plugs for the RJ-45 communications connector on the charger are available

6.8.2. Modbus TCP/IP—Optional
Connect TCP/IP Modbus communications using a twisted pair cable at the RJ-45 connector on the
optional TCP/IP circuit board located on the inside front cover and separate from the
alarm/communications circuit board (see Figures 1-3 for location in charger). TCP/IP Modbus
communications settings must be configured using the DeviceInstaller Software provided by
Lantronix Inc. (see section 11.1
6.9. Load Share Connection—Optional
Multiple chargers may be connected in parallel to provide charger redundancy and increased charging
current. Connect a network cable from one charger to another using the SENSbus RJ-45 ports on each
charger to automatically initiate load sharing. Two SENSbus RJ-45 ports are provided on the inside panel
between the AC and DC connections (see Figures 11-12). The ports are in parallel and either port may be
used for the load share connection.
SENS MicroGenius S2/S4 Technical Manual
for further instructions).

cable to either port
Use of this sharing cable is essential to synchronizing operation of the Dynamic Boost and HELIX modes,
and helps insure that current is shared within +10% between chargers. Chargers intended for load
sharing must be configured with the same output settings in order to load share. Corresponding outputs
must be configured with the same output settings for chargers with multiple outputs. Load sharing
operates independently on each output for chargers with multiple outputs. Connect corresponding
outputs of load sharing chargers in parallel (i.e. connect output A to output A). Load sharing will not
occur if non-corresponding outputs are connected (e.g. do not connect output A to output B). See
section
9.13 for further information.

SENS MicroGenius S2/S4 Technical Manual
6.9.1. Load Share Termination
For proper load share operation, a 120-ohm terminator is required at the ends of the bus.
Termination is provided with the charger using the already installed terminator plug (see Figures
11-12).
6.10. Remote Alarm/Communications Panel Accessory Connection—Optional
The optional remote alarm/communications panel accessory provides the ability to adjust and
communicate with multiple chargers using one external device. The remote panel accessory may be
configured with different alarm relay assignments than the alarm relays native to the charger. Connect
remote accessories to the charger using a network cable connected to the SENSbus RJ-45 port. Two
SENSbus RJ-45 ports are provided on the inside panel between the AC and DC connections (see Figures
11-12). Connect a network cable from the remote accessory to one port and leave the factory installed
120-ohm terminator in the second port. Connect the other end of the network cable to the RJ-45
splitter connected to the RJ-45 port on the remote accessory circuit board.
For proper operation, a 120-ohm terminator is required at both ends of the communications bus.
Remote accessories are provided with a terminator installed in the 2-position RJ-45 splitter connected
to the RJ-45 port located on the remote accessory circuit board. Remove the terminator on the splitter
only if the remote accessory is not at the end of the communications bus.
The remote accessory may be connected to multiple chargers. In this case, the remote accessory,
chargers or other equipment may be located at the ends of the communications bus. Ensure a
terminator is located at both ends of the communications bus.
6.11. Verify Connections
6.11.1. Verify that all connections are secure and in the proper locations. Tighten all unused screws on
terminal blocks to secure them against vibration.
6.11.2. Ensure all wires are routed in a way that the cover or other objects will not pinch or damage
them.

7.2.3. Configuration Code
The Configuration Code indicates charging algorithm and alarm setpoints configured at the
factory. See sections 8 and 9 for further information.
7.3. Apply AC Input Voltage
Verify the AC input is the correct value (90-265 VAC, 47-63 Hz) and apply AC to charger.
Depending on the state of charge of the batteries and the load on the DC bus, the charger may go into
current limit at this time, in which case the output voltage will be reduced as the charger operates in
constant current mode. Eventually as the battery is charged, the charging current demand should taper
to a value below the current limit setpoint of the charger, and the charger should revert to constant
voltage output. Chargers configured to use boost may be in boost for up to 24 hours depending on state
of charge of the batteries.
7.4. Power Off
Power charger off as necessary by disconnecting both AC and DC in any order.

9.1. Charging Algorithms
The charger uses charging algorithms appropriate for different battery types. The charging algorithm for
each battery type includes various combinations of Float mode, Dynamic Boost™ mode, and HELIX mode,
as described in Table 17. See following sections for descriptions of each charging mode.

9.1.1. Recharging Batteries
After a battery has been discharged, the charger will enter Dynamic Boost mode if this mode is
enabled (see section 9.3
increases to the boost voltage value (see section 9.3). If the battery is deeply discharged, DC
voltage will remain below the boost voltage setpoint until the charger’s output current drops
below its rated maximum. Charging in the boost mode continues until the Dynamic Boost control
system ends the boost mode or the boost time limit expires (boost time limit set to 24 hours by
default). After operating in boost mode the charger switches to Float mode (see section

inside cover label for original factory configuration float value.

*Configuration Code displayed on charger label.
9.3. Dynamic Boost™ Mode
Dynamic Boost mode utilizes a higher voltage charge to quickly recharge batteries and ensure that all
battery cells in a battery string are charged to the same level. Dynamic Boost mode automatically adjusts
how long the charger remains in boost mode every recharge cycle. Dynamic Boost automatically adjusts
for differing battery sizes, depths of discharge, varying load, battery age and other variables. Dynamic
Boost mode safely maximizes recharge performance while cutting risks of both overcharging and
undercharging associated with manual or automatic boost timers or earlier generation automatic boost
control systems.
Dynamic Boost is automatically used by the charger depending on battery type selected. See the inside
cover label for original factory configuration boost value. Flooded lead-acid, absorbed glass mat (AGM)
and nickel-cadmium batteries are automatically charged using Dynamic Boost mode when the battery
requires it. Charging in boost mode continues until the Dynamic Boost control system ends boost mode
or the boost time limit expires. The boost time limit is set to 24 hours by default. Since boost charging is
discouraged by most manufacturers of valve-regulated lead-acid (VRLA) batteries used in stationary
applications Dynamic Boost mode is disabled when the charger battery type is VRLA. Boost is also
disabled when the battery type is set to ultracapacitor.
Relatively high boost voltages are appropriate in applications where rapid charge recovery is essential or
required for strict NFPA-20 fire pump or NFPA-110 emergency power system installations. Order
chargers from the factory configured for fire pump/emergency power system installations or configure
the charger appropriately using the keypad or SENS Setup Utility. Use of the optional remote
temperature compensation probe is highly recommended to maximize charging performance and
optimize battery life.

9.4. HELIX Mode
HELIX (High Efficiency, LIfe-eXtending) mode significantly increases the life of flooded lead-acid starting
batteries. Battery engineers confirm that continuous flooded SLI (starting batteries) are all designed for
vehicle use where they are NOT continuously float charged. Continuous float charging
batteries causes these batteries’ polyethylene battery separators to oxidize much sooner than would
occur in vehicles, where charging is intermittent. Premature separator failure in turn causes earlier
failure of the battery than would occur in a vehicle application. Because HELIX allows battery separators
to last their entire design life, HELIX also substantially reduces the risk of catastrophic failure of flooded
lead-acid batteries.

GEN

*Configuration Code displayed on charger label.
flooded SLI
HELIX is active when the charger is set at the factory for flooded lead-acid battery type with
configuration code “GEN” (see inside cover label for configuration code). HELIX operates automatically
and no configuration is required by the operator. HELIX mode can be enabled/disabled using the keypad,
the SENS Setup Utility, or by selecting a different battery type.
HELIX mode adds two DC output voltage settings to the traditional Boost and Float voltages. These are
called Eco-Float and Refresh. The Eco-Float voltage is just above battery open circuit voltage, below
traditional float. Refresh voltage is approximately halfway between Float and Boost voltage.
When HELIX is operating, the charger spends more than 90% of its operating hours in the Eco-Float
mode. In this mode the charger uses less energy and substantially reduces the rate at which water is lost
from the battery. If there are no power outages or other battery discharge events the charger
periodically transitions from Eco-Float mode to Refresh mode to ensure that the battery remains fully
charged. After operating in Refresh mode the charger reverts to Eco-Float mode.
9.5. Ultracapacitor Mode
Ultracapacitor mode is used to charge ultracapacitors rather than batteries. The AC LED will flash green
to indicate ultracapacitor mode. The charger output voltage in ultracapacitor mode is 15V for 12V
ultracapacitors and 25.4V for 24V ultracapacitors. Dynamic Boost mode is disabled for operation with
ultracapacitors.
9.6. Charging Low or Zero-volt Batteries
The charger will initially charge/commission zero-volt or fully discharged batteries without special user
intervention. The charger will charge for approximately 5 minutes to determine if the battery voltage will
begin to rise. If the voltage rises properly the charger will continue to charge the battery normally using

system). After correcting a mismatched condition, cycle AC and DC power to reset the charger and begin
operation.
9.7. Commissioning Batteries
Initially charge/commission zero charge batteries with configurable output voltage and current by
activating Commissioning Mode from the keypad or SENS Setup Utility. Using the keypad, navigate to the
“Battery Set-up” menu to enable commissioning and configure commissioning voltage, current and
duration. Select the appropriate output for chargers with multiple outputs. Each output is configured
independently. Commissioning is not available for VRLA, AGM, power supply and ultracapacitor battery
types. During commissioning the Over Voltage Shutdown alarm occurs at approximately 102% of the

completes, the charger will automatically revert to the settings configured for normal charging, including
temperature compensation and the Over Voltage Shutdown alarm.
9.8. Battery Check
Run a Battery Check test to determine if a battery can support a load. Battery Check will reduce charger
output voltage to a configurable backstop level to permit the battery to support the load. Activate a
Battery Check using the keypad or SENS Setup Utility. Using the keypad, navigate to the “Battery Check”
menu to enable a Battery Check and configure battery check minimum voltage and duration. Select the
appropriate output for chargers with multiple outputs. Each output is configured independently. Upon
completion of the test, the LCD will display whether the test passed or failed for ten seconds or until the
“Enter” key is pressed. If the audible alarm is enabled, a single beep occurs when the battery check
results are displayed. Schedule a Battery Check to run automatically by setting the Scheduled Battery
Check interval in the “Battery Check” menu. An in-progress Battery Check activates a fast flashing green
DC LED. Battery Check failure activates a fast flashing yellow DC LED. Alarm/communications circuit
board BATTERY CHECK relay contacts change to Fail state after delay when alarm is assigned to relay
contacts. Clear a failed Battery Check alarm using the keypad by scrolling to the “Alarms & Settings”
menu then selecting the “Battery Check” option and pressing the UP arrow.

9.11. Configuration with SENS Setup Utility
Use the SENS Setup Utility to program the charger with custom settings rather than using the keypad.
Custom configuration is typically completed by OEMs, qualified dealers/distributors, and packagers. The
setup utility allows configuration of all charger settings including alarm relay assignments.

models, J1939 address 2 (auxiliary charger) is

9.11.1. Connect SENSbus Adapter
Communication between a computer and the charger using the SENS Setup Utility requires
connection of the SENSbus Adapter (shipped with SENS Setup Utility kit). Models with the
optional TCP/IP circuit board include an internal SENSbus Adapter and do not require connection
of a separate device. Connect the provided USB cable from the USB port on a PC to the SENSbus
Adapter port labeled “USB.” Connect the provided network cable from the SENSbus Adapter RJ45 port labeled “SENSbus” to the RJ-45 port on the charger. Two SENSbus RJ-45 ports are
provided on the inside panel between the AC and DC connections (see Figures 1-3 for location in
charger). The ports are in parallel and either port may be used for the SENSbus Adapter
connection. See the SENS Setup Utility user manual for information on configuring the charger.
9.12. Temperature Compensation
The charger is temperature compensated to match the negative temperature coefficient of the battery.
When temperature compensation is active, the output voltage will increase slightly as temperature
decreases, decrease as temperature increases, and is clamped at 0°C (32°F) and +40°C (122°F) to protect
against extremely high or low output voltage (see Figure 16).
The charger automatically includes local temperature compensation using internal on-board sensors.
Remote temperature compensation is enabled when an optional external sensor is located at the
batteries and connected to the remote temperature sensor terminal block in the charger (see
section 6.6
for connections). Chargers with multiple output terminals include multiple remote
temperature sensor terminal blocks (connect one sensor for each output). Remote temperature
compensation is required for ultracapacitor charging and should be used in applications where battery
and charger are located in different ambient conditions. Temperature Compensation is set to a slope of
-0.18% per °C by default for operation with batteries. The temperature Compensation slope for
ultracapacitors is set by the factory and is not adjustable. Temperature compensation is disabled by
connecting a short across the remote temperature sensor terminal block(s), using the keypad or by
setting the temperature compensation slope to zero using the SENS Setup Utility. The temperature
present at a sensor (local or remote) is displayed on the front panel LCD. Actual battery temperature is
only displayed if the optional remote temperature sensor is connected to the charger and placed at the
batteries.

9.13. Load Share Charger Operation
Multiple chargers may be connected in parallel to provide charger redundancy and increased charging
current. Load sharing chargers are fault tolerant; one charger failure will not cause failures in paralleled
chargers.
SENS MicroGenius S2/S4 Technical Manual
9.13.1. Load Sharing and Synchronization
Connection of a network cable between chargers using the SENSbus RJ-45 connectors (see
section 6.9
) automatically initiates load sharing synchronization of operating modes. Chargers will
share the current load within +10%. For proper load share operation, a 120-ohm terminator is
required at the ends of the bus. Chargers intended for load sharing must be configured with the
same output settings in order to load share properly. A charger in a multi-charger load sharing
system with different output settings will not load share properly. Corresponding outputs must be
configured with the same output settings for chargers with multiple outputs. Load sharing
operates independently on each output for chargers with multiple outputs. Connect
corresponding outputs of load sharing chargers in parallel (i.e. connect output A to output A).
Load sharing will not occur if non-corresponding outputs are connected (e.g. do not connect
output A to output B).The LOAD SHARE FAIL alarm will occur any time a charger is unable to load
share. If a charger in a multi-charger load sharing system fails or is disconnected the remaining
chargers will still load share and ignore the faulted charger. Each load sharing charger will alarm
independently using individually configured alarm setpoints.
The output voltage and current of each individual charger will be shown on the front panel LCD. If
an optional remote alarm/communications panel accessory (not included internal to charger) is
connected it will display only the system output voltage and current. An alarm/communications
circuit board that is configured for an individual charger can be set to show system information by
using the SENS Setup Utility.
Chargers connected in parallel without the load sharing network cable will operate but without
synchronization. Current is not shared between chargers, Boost and HELIX modes are not
synchronized and the system voltage is not displayed on the LCD. The chargers must be set for the
same voltage range (12V or 24V) and Float voltage. When load sharing is disabled, boost mode
should also be disabled on all but one charger to avoid conflicts between chargers. As a result,
redundancy of Boost output voltage is not included when load sharing is not employed.

9.14. Remote Alarm/Communications Panel Accessory
The optional remote alarm/communications panel accessory provides additional alarm relay contacts
and the ability to adjust and communicate with multiple chargers using one external device. Connection
of a network cable between the accessory and charger(s) using the SENSbus RJ-45 connectors (see
section 6.10
) automatically initiates communication. For proper operation, a 120-ohm terminator is
required at the ends of the bus. Adjust configuration and view status using the remote panel keypad
and display. See section
9.10 for keypad operation.
10 J1939 COMMUNICATIONS
See data messages below for read-only information available using J1939. Each charger automatically
broadcasts a data message once per second after it has joined the J1939 network. Charger operation
parameters may not be configured using J1939 communications.
In most cases, charger default J1939 settings are sufficient to automatically begin using J1939
communications after connecting the charger to the network. Use the SENS Setup Utility to adjust J1939
settings (e.g. baud rate, vehicle system instance, etc.) if required.

presumed that a module has failed, has lost
SENSbus data communication, or has an incorrect

Too few charger modules operating. The combined
output rating of all modules operating on this
