2 Safety

1. When using the external current measurement

function:

▪ Always replace the CT internal battery before a

test or use the 9 V DC out from TORKEL.
▪ Set the correct current ratio in the external current
measurement menu.
2. Do not use liquid detergents or aero-sols when
cleaning TORKEL or TXL units. Use a damp
cloth.
3. If TORKEL has been stored below freezing for
an extended period of time, you must allow 3
hours for it to adapt to room temperature.
4. At high ambient temperatures and high loads,
TORKEL will employ a heat reduction discharge
scheme that under certain circumstances might
induce a high frequency audible noise. This is
normal, but can be taken as an indication that
TORKEL is working close to its temperature
limits.

Protection system
The unit has built-in protection system against over-
heating and malfunctioning cooling fans. A built-in
circuit breaker is an important component in the
safety system. If the temperature will be too high and/
or the cooling fans malfunction, the circuit breaker
will trip. There is also a melting fuse connected in
series with the circuit breaker.
Always follow the safety instructions in section 2.2.

If there is a long interconnection in a battery string the
voltage drop during a discharge test will affect the cell
voltage value. This voltage drop can be cancelled by
connecting a BVM on each side of the interconnec-

For tests where it is important to obtain
External current measurement must be used when: the desired current within a few seconds

measurement since it provides faster
▪ Testing without disconnecting the regular load.
regulation.
Since total current is measured, TORKEL can compensate
for changes attributable to the regular load. The total
current from the battery is then kept at a constant value.
This ensures accurate test results.
The external current measurement function enables
TORKEL to measure the total current in an external
path and base regulation on this measurement.
A DC clamp-on current probe (optional accessory) has
to be used for this measurement. It can be applied at
one of the battery terminals or at an inter-cell con-
nector. The DC clamp-on current probe must measure
the total current, including that which passes through
TORKEL.
A current shunt can also be used, but this requires
opening the current path and connecting the shunt
in series. The current shunt must be connected to the
negative side of the battery.

WARNING
External current shunt may not be used
above 300 V DC

Important
Always activate the warning and stop
limit functions when using external cur-
rent measurement. This will protect your
batteries if the DC clamp-on current probe
will malfunction.

Important
If a current shunt is used it must be con-
nected on the negative side of the bat-
tery.

Voltage to ground must not exceed 250 V.

The following events can cause an alarm to

be issued
▪ Warning level is passed.
▪ Discharging is stopped because a stop level is reached.
▪ TORKEL can not regulate the current to the desired level.
▪ Thermal protection device trips or a fan does not rotate as
expected.
▪ The connection to the battery is broken.
▪ Other fault situations such as battery voltage too high or
too low or excessive current through TORKEL.

Note TORKEL will safely interrupt the discharge and

issue an alarm if any of the internal tempera-
tures should exceed the safe operating limits.

Resetting the alarm

You can reset the alarm by pressing the information

▪ You must make some simple calculations before starting

a test to find out whether or not TORKEL will be able to
provide the desired load current.
▪ You must also make certain that TORKEL will be able to
sustain this current until the test ends.
When a single TORKEL cannot provide the current you
need, you can:

▪ Connect one or more TXL Extra Loads to TORKEL.

▪ Connect two or more TORKELs in parallel.
▪ Connect two or more TORKELs and two or more TXL
Extra Loads into a single system.

9.2 BVM - Battery Voltage Monitor

The BVM (Battery Voltage Monitor) is a battery voltage measurement device that is used for monitoring of cell
voltages and battery blocks in battery banks commonly found in electrical power sub-stations, telecom facilities
and computer data center UPS systems. In conjunction the TORKEL unit, and test data management software,
such as PowerDB or TORKEL Win, the BVM enables a completely automated battery bank capacity test to be
performed.

BVM is available in three kits:

▪ BVM150 with 16 BVM units

▪ BVM300 with 31 BVM units
▪ BVM600 with 61 BVM units

chained in a single battery bank under test.
The included dolphin-style battery clamp can be easily
removed and exchanged with different styles of stand-
ard banana plug clamps and/or extension cables to
accommodate any battery connection requirement.
There is an Activity LED on the BVM that flashes when-
ever an individual BVM transmits data back to the data
acquisition host computer. This LED activity is useful for
indicating that the device is functioning properly.

Note The BVM readings are continuously ongoing.

A typical reading from a battery bank is
around 30 seconds. Depending on the num-
ber of cells/BVM’s connected.

Test with BVM and TORKEL

WARNING
See the chapter "Safety" for safety pre-
cautions.

1] Connect the BVM units as shown in the con-

nection diagram, see below.
Each BVM is identical and can be connected
in any battery test position. Up to 120 BVMs
can be daisy-chained in a single battery bank
under test.
If you need more than 120 BVMs they must
be connected in two loops, see connection
diagram on next page.

Note The BVM units must be connected following

the battery cell sequence order. The BVM
connected to the “To 1:st BVM unit” port of
the Power and Signal connector must be con-
nected to the most Negative pole of the bat-
tery. The red dolphin clip shall be connected
to the most Positive pole of the battery. The
connection is the same regardless of the cell
numbering selected in TORKEL.
Power up the BVM system after completion of
all the BVM connections.

Fig.9.1 The BVM units must be connected following the

battery cell sequence order. The red dolphin clip shall be
connected to the most Positive pole of the battery.

Connect the first loop to the BVM1 connector on TORKEL and the second loop to the BVM2 connector on TORKEL.
