Introduction
TXL830/850/870 (Extra
Loads)
The TXL830, TXL850 and TXL870 Extra Loads comprise resistive loads. They can be used together with
TORKEL Load Units to increase loading capability. The
TXL Extra Loads can not provide regulatation by themselves but TORKEL measures total current from the
battery and regulates the load characteristic. When
TORKEL is stopped it sends a stop signal to the TXL
Extra Load.
The three models have different maximum voltage
ratings:
TXL830 28 V
TXL850 56 V
TXL870 280 V
TORKEL Win software (optional)
The TORKEL Win program, which runs on a PC under
Windows®, builds up a voltage curve on the screen in
real time and displays the current, voltage and capacity readings. You can also use TORKEL Win to control
TORKEL during the test . The program stores the
results in a text file, and it can generate reports
General
This manual explains how to use TORKEL 820, TORKEL
840 and TORKEL 860 Battery Load Units, and it also
covers the TXL830, TXL850 and TXL870 Extra Loads.
Although performance differs from one model to
the next, all models are used in the same way. Unless
otherwise specified, what is set forth in this manual
applies to all models.
TORKEL 820/840/860
These Battery Load Units are sophisticated instruments designed mainly for capacity tests. All three
units can be programmed to test a battery bank at
constant current, constant power, or using a user-defined load profile. TORKEL can also be used for testing
battery chargers and other electrical equipment that
require resistive load testing.
The three models have different maximum voltage
ratings:
TORKEL 820 60 V DC
TORKEL 840 288 V DC
TORKEL 860 480 V DC
TORKEL has a number of functions that facilitate its
use. Examples include:
Warning and automatic stop functions for
time, discharged capacity and low battery
voltage.
9 memories where settings can be stored.
Voltage curve can be stored for later transfer
to a PC using the TORKEL Win program.
Discharging can be started/stopped from external equipment.
Testing can be carried out without disconnecting the regular load.

Safety instructions
Warning
The electrical voltage and current used in battery
testing is potentially lethal.
Ensure that the AC supply is isolated and any battery under test is disconnected before attempting
any cleaning or maintenance of TORKEL.
Do not connect or disconnect any of the cables
unless the circuit breaker F1 is in the lower (OFF)
position.
Connection and disconnection procedures are extremely important. Be sure to follow the instructions
faithfully.
Do not touch conducting parts of the clamps on the
current cables or the voltage sensing cables when
they are connected to TORKEL.
Explosion risk when using Torkel and TXL (all models)
When a lead acid battery is charged or discharged
i.e. when there is a current flow through the battery
it is always a risk that the battery can explode.
For new open (vented) batteries the risk is medium
to low but in old VRLA (sealed) batteries the risk is
medium to high.
If there is a bad connection inside the battery and
there is a current flow - the connection will burn off
and there will be an arc, which will ignite the oxyhydrogen gas in the battery.
To minimize the risk for personnel injuries:
Always place Torkel/TXL as far away from the battery as possible - use long current cables and/or
remote start/stop.Never stand close to a battery
during charge/discharge.
Too high discharge current applied on a battery can
cause the battery to explode or get over-heated. Be
sure to not set too high current.
If the external current measurement is interrupted
or giving false values during the test, the current will
rise to a higher level than the set value before the
test is shut down. If the battery is too small for this
current or in a bad condition - it may explode.

When using the external current measurement function:
1. Check that the CT is connected in the right current direction.
2 Always replace the CT internal battery before a
test.
3 Set the correct current ratio in the external current
measurement menu.
Never use the TORKEL/TXL Extra Load in an explosive environment. Never put the TORKEL/TXL Extra
Load where it can be reached by battery gas.
Improperly connected cables carrying high current
can cause fire. Make sure that the cables are not
twisted in such a way that could cause them to turn
and come loose from the connector.
Position TORKEL/TXL Extra Load where air flow is
unobstructed and where it does not come into contact with any flammable or heat-sensitive material.
Keep a free distance of 1.5 m (5 ft) to the vertical sides of TORKEL/TXL and 2.0 m (6.5 ft) above
TORKEL/TXL.
Do not place TORKEL a) near another TORKEL, a TXL
Extra Load or any other heat source or b) where the
cooling airflow can be blocked. TORKEL will overheat if there is insufficient cooling.
External current shunt may not be used above
300 V DC
Important!
Make sure that the clamp-on ammeter is properly
connected and that its battery lasts throughout
the entire test. If external current measurement
malfunctions, TORKEL might provide a higher load
current than intended.
Do not use liquid detergents or aero-sols when
cleaning TORKEL or TXL units. Use a damp cloth.
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.

Testing at constant
power / resistance
Constant power
TORKEL can be used to conduct a discharge test at
constant power instead of constant current. All procedures are the same except that you must set TORKEL
differently before starting – you set the power instead
of the current.
Warning
See the chapter "Conducting a test" for
safety precautions and how to prepare
the test.
Important
When testing at constant power, the current will increase as the voltage decreases.
Calculate the current at the end of the
test (W / V = A). Then make sure that the
total current does not exceed 2999 A.
Also make sure that the TORKEL and TXL
units can provide the required current
load troughout the test.
Configuring TORKEL for
constant power

External current
measurement
Applications
• External current measurement must be used when
TORKEL is working together with TXL Extra Loads.
• Testing without disconnecting the regular load.
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.
TORKEL used together with TXL Extra Load
Constant current, regular load connected.
• Two or more TORKEL and TXL units ca be used for
discharging at up to 2 999 A.
General
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 ammeter (optional accessory) has to
be used for this measurement. It can be applied at
one of the battery terminals or at an inter-cell connector. The clamp-on ammeter 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 conected to the
negative side of the battery.
Warning
External current shunt may not be used
above 300 V DC
Important
The current shunt must be connected on
the negative side of the battery.
Tip
For tests where it is important to obtain
the desired current within a few seconds
or less it is better to use internal current
measurement since it provides faster
regulation.

batteries if the DC clamp-on ammeter
were to malfunction.
Connections
Warning
Make sure the polarity is correct.
Connect the clamp-on ammeter to the EXTERNAL
CURRENT MEASUREMENT input. Best results are
obtained if the cables running from the clamp-on
ammeter are twisted.
Apply the clamp-on ammeter to the conductor.
See the figures in the section headed “Applications”.
Note: The arrow on the clamp-on ammeter must
point in the same direction as the current flow.
Note: The clamp-on ammeter must always be applied in such a way that current through TORKEL is
included in the measurement.
Turn on the power switch on the clamp-on ammeter.

Troubleshooting
If the following message appears when you start the
test:
Error:
External I
Check that the clamp-on ammeter is properly
connected to TORKEL. Also check the polarity.
Check that the clamp-on ammeter is switched
on.
Check that the clamp-on ammeter has fresh batteries.
Make sure that the clamp-on ammeter is
clamped in the correct direction. A DC clamp-on
ammeter normally has an arrow which should
point in the direction which current flows through
the conductor.
Check the folowing settings in “Basic setting”
submenu:
• “I measurement” must be set to “External”.
• The mV/A ratio must match the ratio that appears on the clamp-on ammeter itself.

TORKEL Win
program
The TORKEL Win program builds up a voltage curve
on the screen while the test is running and presents
the current, voltage and capacity values in a scrollable table. Moreover, you can control TORKEL from
TORKEL Win during the test, print out a report and
store the measured values in a text file, which can be
imported easily into Microsoft® EXCEL.
Because TORKEL always stores the total voltage curve
during the test (one curve can be stored), you can also

Calculating current
General
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. TORKEL regulates current by lowering its internal resistance as the voltage
drops. However, the resistance elements built into
TORKEL impose a limit beneath which further lowering
is impossible.

P r o g r a mm a E l e ct r i c A B
Z P - B S0 6 E R 1 01
Imax
Check that the desired current load is not greater than
the Imax for the TORKEL unit in question (column 2 in
the tables above).
Max power
For the 10 – 480 V range on TORKEL 860, you must
also check to see that current multiplied by maximum
voltage does not exceed the 15 kW power limit.
Final voltage
If the final voltage is lower than the value set forth in
column 4 (in the table above), the internal TORKEL
resistance will limit the current so that it will be impossible to reach Imax (column 2 in the table above). In
such case, you can calculate the current that will be
obtained at the final voltage as follows:
Add the TORKEL internal resistance (column
3) to the cable resistance (which is 1.5 mΩ for
TORKEL 820 and 4 mΩ for TORKEL 840/860 if you
are using standard cables).
Subtract 2.2 V from the final voltage and divide by the resistance you obtained in step one
(above).
Example: The final voltage is 10.8 V, and you want
to find the maximum possible current at this voltage if
you are using a TORKEL 840 and the voltage range is
10 – 27.6 V.
Calculate the resistance as follows:
0.165 Ω + 0.004 Ω = 0.169 Ω .
Calculate the maximum current as follows:
(10.8 V – 2.2 V) / 0.169 Ω = 50.9 A.

When a single
TORKEL isn’t
enough
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.
When two or more TORKELs are connected into a single system, you will normally use the “External current
measurement” function. But in situations where it is
important for current to be regulated to the correct
value within a second or so, it is better to use two or
more TORKEL units set for internal current measurement and no TXL Extra Loads since these latter must
be started manually. To obtain the total current, you
must then add the current values (amperages) shown
on all TORKEL units. The TORKEL units can be started
and stopped synchronously via the START/STOP input.
TXL Extra Loads connected
to TORKEL
TXLs are resistive loads which are unable to provide
any sort of regulation. Regulation is provided by
TORKEL which measures the total current and keeps
it constant. See the chapter headed “External current measurement” which shows how to connect the
TXL(s) and TORKEL(s).
When TXL Extra Loads are connected to TORKEL, you
must check:
That the current flowing through the TXLs
when the test is started is not higher than
intended.
That TORKEL has enough regulation capability a) to compensate for the drop in current
through the TXLs at the end of the test and
b) to set the current to the correct value at
the beginning of the test.
•
•
•
•
•
Calculating how many
TORKELs and TXLs are
needed
1. Number of TXLs – Current flowing through TXL(s) at beginning of
a test
At the beginning of the test, as high a percentage as
possible of the current must flow through the TXLs,
thereby providing the TORKEL(s) with as much reserve
regulation capability as possible. However, the current
through the TXLs must not, of course, exceed, the
desired current value (A).
Note Remember that the internal resistances of
the TXLs can be set manually. For accurate
calculation, add the cable resistance to
the internal resistance.
A. The current in an individual TXL can be obtained by
dividing the voltage at the beginning of the test by
the internal resistance of the TXL in question (see
tables below).
B. Calculate the number of TXLs that you can connect
without exceeding the desired total current.
2. Current flowing through TXL(s)
at final voltage
A. Multiply the total current through the TXL(s) which
you obtained in step 1 above by the final voltage,
and then divide by the voltage at the beginning of
the test.
3. Number of TORKELs – for the
current regulation
The TORKEL or TORKELs in the system must regulate
the current to the desired value and compensate for
the drop in current through the TXL(s) that occurs at
the final voltage.
A. The amount of regulation needed can be obtained
by subtracting the current value (A) obtained in step
2 above from the desired current.
B. Calculate the number of TORKELs required for the
current regulation.
4. Are all of the TXLs needed?
If the total load-providing capability of the TORKEL(s)
exceeds the amount of regulation needed by a wide
margin (as set fort in step 3 above), you can perhaps
conduct the test with fewer TXLs. If this margin is
wider than the current through one of the TXLs at the
final voltage, this TXL is not needed.

Example
A lead-acid battery with 54 cells has to be tested at
250 A.
Voltage at the beginning of the test (Vstart) is:
116.1 V (54 x 2.15 V)
Voltage at end of the test (Vend) is:
97.2 V (54 x 1.80 V)
Since the current is so high, you must use TXLs . A
TXL870 is suitable since it is rated for the voltage in
question.
1 – Number of TXLs – Current flowing
through TXL(s) at beginning of a test.
The current through a TXL870 set for a resistance of
2.48 Ω is 46.8 A, and current through a TXL870 with
a resistance of 1.24 Ω is 93.6 A. If two TXLs are set to
1.24 Ω and one TXL is set to 2.48 Ω the current will
be 234 A, and they can be connected without having
the current exceed 250 A.
2 – Current flowing through TXL(s) at final
voltage.
234 A x 97.2 V / 116.1 V = 196 A
3 – Number of TORKELs – for the current
regulation.
250 A – 196 A = 54 A. A single TORKEL 840 is
enough for this.
4 – Are all of the TXLs needed?
The loading capability of the TORKEL unit is 110 A at
the final voltage. This exceeds the amount needed by
110 A – 54 A = 56 A. This unused margin is perhaps
wide enough to eliminate the need for one TXL. At
the end of the test, the current through the TXL that
is set to 2.48 Ω is 97.2 V / 2.48 Ω = 39 A. Since the
unused TORKEL margin is wider than 39 A, this TXL is
not needed.

Test conducted
using a system
comprising TORKEL
and TXL units
One of the TORKEL units (we shall call it TORKEL No.
1) is to measure the entire battery current. TORKEL
No. 2 measures all current except the current through
TORKEL No. 1. TORKEL No. 3 measures all current except the currents through TORKEL No. 2 and TORKEL
No. 1 (and so forth). The last TORKEL measures only
the current through itself and the TXLs.
Example of a system comprising TORKEL and TXL units.
Hookup and settings
Warning
The chapter headed “Conducting a test”
presents safety precautions and explains
how to prepare for testing. Be sure to
comply with what is set forth in this chapter.
Apply the clamp-on ammeters as illustrated
above.
1]
Set the desired total current (same value) on all
TORKEL units.
As a result, the maximum regulation capability of
all TORKEL units will be used. You do not need to
pay any attention to the message reading “Cannot regulate” as long as it does not appear on
TORKEL No. 1.
Set warning limits only on TORKEL No. 1.
Set the stop limits. The voltage and test period
(time) can be set on each individual TORKEL. Stopping after a certain capacity (Ah) is reached can
only be activated on TORKEL No. 1.
Note Only TORKEL No. 1 is to control the TXLs.
Only TORKEL No. 1 is to be connected to
the PC.
Starting discharge
Set switch <F1> to the upper (ON) position on the
TXLs.
Then start the TORKEL that has the highest
number (when numbered as set forth above).
Now start the TORKEL with the second highest
number, then the third highest, etc. Finally, start
TORKEL No. 1. Starting the TORKELs in this order
prevents the current from being higher than
desired at the beginning of the test.

Troubleshooting
When you first connect a higher
voltage to TORKEL and then a
lower voltage, you may have to
wait for some time.
•
“Error: Connection”
TORKEL has indicated that the battery voltage has
disappeared.
Check the connection to the battery.
•
“CHECK F1”
This message appears if the current is 0 A when current should be flowing.
Check that circuit breaker F1 is
switched on.
•
“CHECK F1 Input voltage “
Check that circuit breaker F1 is
switched on, that the battery is
properly connected and that the
battery voltage is not less than
10 V.
•
“Unable to regulate”
The message appears when TORKEL can not regulate
the current (or power or resistance) to the desired
value.
The TORKEL-unit can not regulate because it can not
decrease its resistance further.
You must decrease the current
or connect more TORKEL or TXL
units.
•
This is not a fault-situation if the
actual TORKEL is operating in a
system of several TORKEL units
and another TORKEL (TORKEL nr 1)
takes care of the total regulation.
•
"Error: External I”
The measured external current is less than the internal current
See also chapter headed “External Current Measurement”.
Display on TORKEL is dark.
Check that the mains cable is properly plugged in.
•
Check the mains voltage•
Impossible to switch on the circuit breaker
F1.
It is only possible to switch on F1 in the “Test battery”
submenu. Furthermore, you must:
Connect the battery to TORKEL
Set the current
Wait for message reading “Switch on
F1”.
Push the lever of F1 to the ON position a second time if it does not latch
directly.

You responded to the “Switch on F1” message by
pressing <ENTER> without switching on F1.
You have accidentally switched off F1 manually.
TXL connected to TORKEL
When a TXL and TORKEL are connected via the signal cable
connected to the ”Control In” input, the following can happen:
Impossible to switch on the circuit breaker
F1 on the TXL-unit.
You have not received the message “Switch on F1” on
TORKEL.
You have not connected the input CONTROL IN properly to TORKEL.
The TXL have no mains power. If the fans are not

Call for service.•
“Overcurrent”
The current through TORKEL is higher than allowed
because of a fault in TORKEL´s internal current limitation.
“Input voltage too high”.
The battery voltage is higher than specified for your
TORKEL.
“Input voltage > 27.6 V”
“Input voltage > 55.2 V”
“Input voltage > 144 V”
“Input voltage > 288 V”
“Input voltage > 480 V”
When you connect the battery, TORKEL will automatically select the voltage range and arrange the internal
resistors for highest possible current.
If one of the messages above appears, TORKEL has
stopped because the input voltage has increased and
exceeded the range. You can continue the test but
TORKEL will choose a higher voltage range and rearrange the internal resistors.
Note: The current rating for the new range is probably lower than the previous range (see chapter
headed “Specifications”).
“Input voltage too low”
The battery voltage is too low (less than 10 V, which
is frequent on defective batteries) for safe operation
with TORKEL.

Calibration
procedure
TORKEL has four circuits used for testing that require
calibration:
Internal current
Internal voltage
External voltage
External current
The calibration procedure has four main steps:
Calibrating zero levels
Calibrating internal current (Int I)
Calibrating internal and external voltage (V)
Calibrating external current (Ext +I)
For main steps 2, 3 and 4 you can decide whether or
not to perform them.
Note Calibrate once a year to maintain proper
accuracy.
Stable voltage and current sources (which vary
less than 1% per second) and accurate reference
instruments must be used. The current source
must be able to supply high current at a voltage
between 10 and 30 V. One or two 12 V batteries
can be used here.

Resetting TORKEL
General
This procedure has two purposes:
• To set the calibration values to calculated
standardized values (useful if the calibration has
become invalid or is lost).
• To restore the contents of the control memory
after a message reading “Checksum error” has
appeared.
Resetting TORKEL can never be fully equivalent with
regular calibration carried out using accurate and
traceable reference instruments. However, it provides
you with a quick and simple way to deal with a situation in which no calibration values at all are available.
The result of the reset procedure is about 1 to 3%
accurate except for the external current measurement
where the accuracy will be poorer. Resetting must
always be followed by calibration of the zero levels,
which is a part of the regular calibration procedure. A
complete calibration procedure should be conducted
as soon as possible however.
It is possible to combine resetting and calibration. First
perform a reset and then calibrate the measurement
ranges for which required sources are available. Answer “No” for the ranges that cannot be calibrated.
Standard calibration values will then be used for these
ranges.
Note When a reset is performed on TORKEL the
settings will be changed to the factory
(default) settings.
Performing a reset
Press the <ESC> key and the arrow up () key
simultaneously while switching on TORKEL.
Press <ENTER> to confirm the reset as promted
on the display.
