To measure the fill level, we recommend the immersion tube sensor of the TGT or TGW series for
fuel and fresh water as well as the ultrasonic sensor UTV for faeces tanks and the flow rate sensor
DFS (fresh water only). For deep tanks up to 200 cm and a very precise measurement, the pressure
sensor TDS200 (water/diesel/faeces) or TDW200 (water/faeces).
However, these sensors are not included in the scope of delivery.
Sensors from other manufacturers can also be connected. The display is configured to the
connected sensors in SETUP. Furthermore, an adjustment to the tank geometry is possible in order
to correctly display the actual tank content.
Please note: only with the DFS
flow sensors is the litre display accurate, as litres are also measured here. With all
other sensors, this is only a conversion of the measured fill level and, depending on the
sensor accuracy, can never be accurate to the litre!

3. Assembly and installation
3.1 Monitor
Mount the battery monitor in a protected,
dry and clearly visible place so that it can be
read at any time. The required mounting cut-
out is 85x85 mm, the required minimum
depth is 35mm. On the rear side there is a 3-
pole terminal for the power supply of the
monitor and the communication line to the
shunt SHE and SHP. The tank sensors are
connected via the 9-pole terminal. A
potential-free relay contact is available via
the 2-pole terminal.
A software update can be loaded onto the
monitor via a micro-SD card on the back.
The power supply to the monitor can be interrupted at any time without losing battery status data,
as this is stored in the SHE 348 shunt.
Therefore, the shunt SHE 348 should be permanently connected to the battery. If the monitor is
switched off, the shunt SHE goes into sleep mode and the current consumption of the shunt drops
to 2 mA. This is not a particular load on the battery. However, if the battery system remains
without charge for more than 3 months, the shunt should also be disconnected from the battery.
The following figure gives an overview of the connection of the monitor and the shunt SHE 348.

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 5
The LIN bus connection between the monitor and the shunt is made via a 1-wire cable. This can
also be any or an existing cable. For mechanical reasons, the cable cross-section should be min.
1mm² and max. 1.5 mm².

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 6
3.2 Shunt SHE for battery monitoring
Mount the shunt SHE 348 in a protected, dry place as close as possible to the battery. The shunt
must be connected in the MINUS path of the battery.
Install the active shunt SHE 348 as close as possible to the service battery. However, avoid the
shunt making contact with the positive - terminal of the batteries. Connect the side of the shunt
marked B- to the negative terminal of the main battery using a short, thick cable (35-70 mm²).
Connect the negative terminal of up to two starter batteries to the side of the shunt marked V-.
Note: If the main battery consists of several batteries connected in parallel, their common negative
terminal must be connected to the side of the shunt marked B-. The negative cables of the starter
batteries are connected to the other side (V-) of the shunt. We recommend that all negative
connections of the consumers, charging devices and the negative terminals of the starter batteries
are combined on a ground busbar and that a short cable is laid from there to the V- connection of
the shunt.- Connect the measuring lead of the shunt to the positive terminal of the main battery
via an inline fuse holder (1A). This line measures the voltage of the main battery and
simultaneously supplies the shunt with current.
It is important that no other cables are connected between the B- terminal and the
battery MINUS terminal, otherwise not all currents will be detected and the battery
management system will not work. All cables of the vehicle electrical system
including the connection cable to the starter battery must be connected to the V
side of the shunt SHE 348.
After applying the operating voltage to pin +1, the shunt goes into operation and indicates the
operating status via the integrated LED:
- Rapid flashing during firmware update of the shunt SHX
- Flashing every 1 sec. Normal operation
- Flashing every 5 sec. Sleep mode (power saving mode) when monitor off
The following connections are available on the shunt at the 5-pin connector:
Consumers, charging sources, starter
batteries
Monitored battery group

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 7
1: Battery voltage measuring lead (+1) and at the same time power supply for shunt
This line is absolutely necessary for the function of the shunt and should only be disconnected
during winter storage to enable a complete recording of the battery capacity. Due to the very low
current consumption in sleep mode, the shunt does not place any additional load on the battery.
2: Voltage (+2) second battery group
Optional connection of a voltage measurement of a second battery group (starter battery), this is
then displayed as a second battery group on the monitor.
3: T-: Minus temperature sensor (brown wire) T+: Plus temperature sensor (blue wire)
Optional temperature sensor (Temp-BT) for recording the battery temperature. The temperature
sensor should be fixed to the outside of the battery housing. The temperature sensor has no active
influence on the capacity calculation or charging, but is only used for information.
4: LIN bus communication with display
The BLS monitor communicates with the SHE 348 shunt and the ACE charger via this line.
3.3 Shunt SHP for current measurement
Mount the optional shunt SHP for measuring the solar current or similar in a protected, dry
location as close as possible to the battery. The shunt must be connected in the MINUS path of the
solar system.
Connect the negative pole of the solar system to the side of the shunt marked V-.
The following connections are available on the shunt at the 5-pin connector:
1: Battery voltage measuring lead (+1) and at the same time power supply for shunt
This line is absolutely necessary for the function of the shunt and can be disconnected at any time
when the monitor is switched off.
4: LIN bus communication with display
The BTM2 monitor communicates with the SHP shunt via this line. This line can be realised with
any cable, preferably with 1 mm² cross-section.
3.4 Interface ACE-LIN (optional accessory)
To communicate the BTM2 monitor with an ACE series charger, an ACE-LIN interface must be
inserted into the ACE charger. For the models ACE 12/60 and ACE 24/30, the integrated monitor
must be removed and replaced with the interface ACE-LIN.

Inserting the rubber cable grommet Inserting the cover and the cable.
Inserting the interface board ACE-LIN
Make sure that the ACE charger is disconnected from the
AC mains before starting work.
After removing the front cover, the setting of the DIP switches must be adjusted for operation with
the CAE-LIN interface.
The ACE chargers are equipped with DIP switches to adjust the charging
characteristic individually to the batteries. Only if the DIP switches of the
charger are set to ABCD = "1111", the charging characteristic can be adjusted
from the monitor BLS. Then it is also possible to set a user-defined
characteristic curve. Otherwise, the characteristic curve set via the DIP switches
applies.
For the electrical connection of the interface board, the 16-pin connector of the ribbon cable must
be plugged into the matching red connector on the main board of the charger ACE.

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 9
The interface board is held in place by three plastic clips on the housing.
Wiring LIN line to monitor BLS / shunt SHE
The communication connection "LIN" of the interface ACE-LIN is connected to the connection "LIN"
of the shunt SHE 348 and the monitor BLS via a 1-wire connection cable. This can be decided
according to the local installation conditions. The order of the units on the "LIN" line is irrelevant.
Since the "LIN" connection on the ACE-LIN interface is duplicated, it is advisable to lay one LIN line
from the monitor to the charger and the other from the charger to the shunt. The ideal conductor
cross-section for the "LIN" cable is 1mm².
IMPORTANT: The monitor, the shunt and the charger must have the same negative potential, i.e.
be connected to a common negative point (battery negative).

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 10
3.5 Electrical connection tank sensor
Up to four tanks can be monitored
simultaneously.
However, if fewer tanks are monitored, the
first tank sensor is connected starting at
connection TG 1 (e.g. with 2 tank sensors,
only connections TG 1 and TG 2 are used).
Resistance sensor (e.g. TGT/TGW) and active
tank sensor (e.g. pressure probe TDS) can be
connected in mixed form.
The connection is made according to the
adjacent diagram
A flow sensor DFS can only be connected to
DFS (DFS + /Minus/DFS S)!
ATTENTION: If
the power supply (red line) of the ultrasonic
tank sensor is not via the BTM, but directly
via the DC on-board power supply, the supply
line must be protected with a 1A fuse!
The minus lines of the tank sensor must be
connected to the minus (-) terminal to avoid
incorrect measurements.

The setting "Threshold night mode" is used to calibrate the light sensor in automatic mode. For
calibration, the light sensor (left centre of the display) must be covered with the finger and the
value in brackets must be read. Add two to this value and enter it by pressing briefly. If the
measured value falls below the set value, the display is dimmed. If the measured value exceeds the
set threshold +10, the display is illuminated normally again.
4.3 Battery management
For proper function, the following data must be set during commissioning:
If the battery was not fully charged at that time, it is mandatory to fully charge it in order to
synchronise the display with the battery charge level.
- Name
- Nominal capacity of the battery (Chap. 5.3)
- Rated voltage of the battery group (Chap. 5.4)
- Battery type (chap. 5.6)
- Ah Efficiency factor (CEF) (Chap. 5.9)
- Peukert exponent (Chap. 5.10)
- Cycle depth (chap. 5.11)
- Shunt Info
- Name Battery 2 / 3
4.3.1 Name
This name is shown in the battery symbol of the display and is used for easier assignment.

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 13
4.3.2 Nominal capacity
The nominal capacity of the battery (1-9999Ah) is set here. To obtain a meaningful accuracy of the
remaining time function as well as the percentage charge display, the capacity of the battery to be
monitored must be set.
Please note that the battery capacity should only be adjusted when the batteries are 100%
charged, as this procedure sets the capacity indicator to 100% and all internal counters to 0.
If the battery was not fully charged at that time, this is mandatory to synchronise the display with
the battery charge level.
4.3.3 Rated voltage
Please set the nominal voltage 12 or 24V / 36V / 48V of the battery group so that the capacity
calculation can be done properly.
4.3.4 Battery type
To adjust the "battery empty" and "battery full" detection, the type of battery used [GEL, NASS,
AGM, Lithium, INDIV] must be entered.
4.3.5 Ah Efficiency (CEF)
Every battery has an Ah efficiency. This means that more ampere-hours must be loaded into the
battery than can be removed. The efficiencies of lead batteries are between 80% and 95%. If the
CEF deteriorates below 70% during operation, this basically means that the battery has reached
the end of its life and needs to be replaced. The factory default setting is 95%. The CEF is
automatically adjusted during operation by means of a sliding average over the last 4 cycles.
4.3.6 Cycle depth
The cycle depth indicates the % value by which a battery must be discharged and charged for a
charge cycle to be counted. For starter batteries a value between 10-20% should be set and for
GEL batteries up to 50% can be set. The value represents the cycle stability of the battery, i.e. how
much the battery can be discharged without reducing its life.
4.3.7 Peukert Factor
The capacity of lead-acid batteries is usually specified for a 20-hour discharge. This means, for
example, that a 100 ampere-hour battery can deliver 5 amps for 20 hours before the battery is
empty. If the discharge current is higher, for example 10 amps, the battery is not able to deliver
the full 100 ampere hours. In this case, the battery voltage drops below the lower limit of 10.8 V
for 12V batteries before the battery has delivered its rated capacity.
This relationship can be captured mathematically with the Peukert equation.
In the residual time function, this equation is used to adjust the residual time at high discharge
rates. Under normal circumstances, the Peukert exponent does not need to be changed.

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 14
Usually, the Peukert exponent is set to 1.27 for lead batteries, if no deviating values are available,
and to 1.02 for lithium systems.
4.3.8 Name2
This name is displayed in the battery symbol of the additional battery and is used for clear
assignment.
4.3.9 Name3
This name is displayed in the battery symbol of the additional battery and is used for clear
assignment.
4.3.10 Shunt type / software version / update
The type of the connected shunt and its software version are displayed. A firmware update can be
uploaded to the shunt via the item "Update software" if a corresponding file (PB99R1) is available
on the SD card. To do this, the shunt must be de-energised (disconnect the green plug on the
shunt) and then press the START button. Within 30 seconds, the shunt must be supplied with
power again (plug in the green connector on the shunt) so that the update process is started. The
successful process is then displayed on the screen.
4.4 Charger
The following settings can be made:
- Charging characteristic
- Charge Control (control of the charging process by the charger or the battery monitor)
- Info on which charger is connected (ACExx) and its software version
- Software version of the ACE-LIN interface
The current charging parameters of the set characteristic curve can be read in the 4 following
fields. If the individual charging characteristic is selected, these settings can be edited:
- Maximum charging voltage (boost)
- Max. Boost duration
- Float charge voltage (float)
- Current threshold in % of the maximum power for switching to trickle charge

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 15
If no philippi ACE series charger is connected or the charger is not supplied with mains voltage, no
settings can be made.
4.5 Alarm
A tank alarm is always indicated by the associated tank symbol flashing. A battery alarm is always
displayed in the battery symbol. In addition, the alarm can be issued/configured as follows:
- optical Display illumination flashes
- Audible internal buzzer
- Relay contact potential-free relay (max. 1A)
The optical and acoustic alarm can always be acknowledged in advance by touching the screen or
can switch off automatically after a definable time.
Alarm options:
Tank alarms:
An alarm threshold can be set individually for each of the 4 tanks. The following settings are
possible:
0 %Alarm off1
..50 %. Empty alarm: if the fill level falls below the set value,
alarm is triggered. The alarm triggering is delayed by 15s.
51... 99 % Full alarm: if the fill level rises above the set value,
the alarm is triggered. The alarm is delayed by 15s.
The alarm is automatically cancelled as soon as the value has changed by 5%.
By briefly pressing the respective line, the acoustic alarm can be switched on or off. By pressing
and holding (> 2s), the respective threshold value can be edited.

Battery/Tank Monitor BTM2
REV 1A - FEB 2022 - Software Version 1.xPage 16
Battery capacity alarms
A message appears on the monitor to charge the battery (battery appears red) if the battery falls
below the set capacity threshold.
The alarm for the alarm capacity is preset to 50%. For an average application, this value is usually
fine; however, the alarm can be adjusted according to the application's requirements.
If the state of charge drops further, 2 different thresholds take effect: Battery reserve (20%) and
battery deep discharge (0%). An alarm is triggered here depending on the configuration.
Battery voltage alarms
If there is a voltage >1V at the shunt on the terminal (+2) for the 2nd battery voltage, this is
reported as another battery. If the battery voltage drops or exceeds the set threshold value for 30
s, an alarm can be generated.
The following settings are possible in the alarm menu:
- Visual alarmLighting flickers (on / off)
- Alarm auto off0-255 sec (Attention 0 = always on)
- Relay auto off 0-255 sec (Attention 0 = always on)
The potential-free relay and the buzzer can be configured for individual alarms. Depending on the
configuration, the alarm switches on for the following alarm states and remains on until all
pending alarms have been cancelled. If an alarm has been acknowledged and a new alarm is
added, the buzzer is activated again.

250). The calibration is carried out in the TRIM menu, where the corresponding current
measurement values can now be entered or determined for the levels 0, 25, 50, 75 and 100%.
4.6.3.8 SENSOR TYPE DFS -
For this setting you need a philippi DFS flow sensor. The connection is only possible to DFS S. The
following symbol appears under the respective tank in the main menu:
Since this sensor cannot detect whether the tank is being filled, you must enter the fill level
manually. Pressing the assigned button takes you directly to the tank menu where you can set the
fill level accordingly. If water
flows through the flow sensor DFS, this is indicated by the rotating symbol. The DFS with arrow
pointing downwards empties the corresponding tank in the display.
4.6.3.9 SENSOR TYPE DFS +
See 4.6.3.8 - Differently, this setting fills the associated tank. This is useful to record the amount of
fresh water produced when using a watermaker.
A maximum of one (1!) DFS can be connected to the BTM!
4.6.3.10 SENSOR TYPE TRS/RSW/DSW:
For this setting you need a philippi TRS float switch (mounted on top of the tank) or philippi
RSW/DSW (mounted on the side). The tank display remains at 0% until the float switch switches
through - the display then goes to 100%. No series resistor is necessary!
4.6.3.11 SENSOR TYPE GOBIUS4
The voltage output of the Gobius control unit must be connected to a tank input. The level is
displayed in 4 steps. The internal settings of the Gobius system cannot be changed from the BTM.
They must be adjusted via the Gobius display.
4.6.4 Adaptation
To adapt the level indicator to a non-rectangular tank geometry,
you have the option of adjusting the characteristic curve. The

respective default settings from the selected sensor type can be adapted to the individual
conditions. This is mandatory for the tank types User R, User U, TDS:
Method 1 (tank is filled step by step):
the probe is in the empty tank. In the Setup menu, go to the setting value for 0% and read the
measured value in the middle at the bottom and enter it in the Level 0% field. Then fill the tank to
25% and enter it in the Level 25% field. Proceed in the same way with the values 50%, 75%, 100%.
This method has the advantage that even with an unusual tank shape, the content is reproduced
correctly.
Method 2 (installation e.g. TDS200 with full fuel tank):
the probe is outside the tank. In the setup, go to the setting value for 0% and read the measured
value in the middle at the bottom and enter it in the Level 0% field.
Then install the probe and read the reading in the middle at the bottom and enter it in the Level
100% field. To get the values for 25%, 50% and 75%, you must first divide the difference between
the values 0% and 100% by 4. Add this value to the value at 0% - this way you get the input value
for 25%. By adding correspondingly more, you get the values for 50% and 75%.
You can enter these values at the setting values for 25%, 50% and 75%.
Method 3:
You know the values for 0%, 25%, 50%, 75% and 100%? Then enter these values directly in the
corresponding settings.
4.7 Energy source
The current and the landed capacity are displayed in the lower left part of the main screen. The
following settings are available.
4.7.1 Name
This battery symbol is displayed on the main screen and is used for clear assignment.
4.7.2 Reset counter
The capacity counter can be set to zero again.
4.7.3 Shunt type / software version / update
The software version of the SHP shunt is displayed. A firmware update can be uploaded to the
shunt via the item "Update software" if a corresponding file (PB99R1) is available on the SD card.
To do this, the shunt must be de-energised (disconnect the green plug on the shunt) and then
press the START button. The shunt must then be restarted within 30 seconds (plug in the green
connector at the shunt) so that the update process is started. The successful process is then
displayed on the screen.
