2 SAFETY
10. 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.
11.
if the external current measurement is inter-
rupted 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.
12.
Never use the TORKEL/TXL Extra Load in an explo-
sive environment. Never put the TORKEL/TXL Extra
Load where it can be reached by battery gas.
13. improperly connected cables carrying high cur-
rent 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.
14. Make sure that there is no dust or dirt in or
around the cooling fans before starting a
discharge test. After starting a discharge test,
check that the fans are running properly and
that the airflow is good. Make sure no hair or
clothing is sucked into the fans.
15.
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.
16.
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.
17. External current shunt may not be used above
300 V DC
18.
Do not use any other equipment other than
what is provided or specified.
Important
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.
