9.1 TXL830/850/865/870/890
(Extra Loads)
The TXL830, TXL850, TXL865, TXL870, and TXL890
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 regula-
tion 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.

Panel
The panels for the TXL models differ somewhat but
the functionality is the same.

1.
Selector switch
Switch used to set the desired voltage range and/
or resistance value.
WARNING
Do not exceed maximum voltage.
2. Control
CONTROL IN
input for control signal from TORKEL-unit. Gal-
vanically isolated.
CONTROL OUT
Output used for the control signal sent from
TORKEL to the adjacent TXL-unit. Galvanically
isolated.
3. Circuit breaker
F1
Voltage-controlled circuit breaker that connects
the resistors in the TXL Extra Load to the battery.
Note F1 will not latch or remain at upper (ON)
position unless the mains switch is turned on and
a control signal from TORKEL is present at the
“CONTROL iN” input..
WARNING
The circuit breaker F1 is an important com-
ponent in the safety system. If the tempera-
ture will be too high and/or the cooling fans
malfunction, the F1 will trip. It is important
to never operate the unit if there is any dam-
age or malfunction to the circuit breaker or
if any damage or malfunction is suspected.
4.
Mains inlet
MAINS
Connector used for mains supply, equipped with
ON/OFF switch.
5. Connection terminals for the battery
+ (Terminal)
Positive (+) current connection for battery or
other DC source, being tested.
– (Terminal)
Negative (-) current connection for battery or
other DC source, being tested.
insulation voltage to ground: 2200 V
Using the TXL
When an extra load is to be used, you must use
the external current measurement function (see the
chapter headed "6 External current measurement" on
page 28).
