PRECAUTIONS IN USING THE TIMERS
7. Operating environment
1) Use the timer within the ambient tem-
perature range from –10°C to +50°C
+14°F to +122°F
LT4H series) and at ambient humidity of
85% RH maximum.
2) Avoid using the timer in a location
where inflammable or corrosive gas is
generated, the timer is exposed to much
dust and other foreign matter water or oil
is splashed on the timer or vibrations or
shocks are given to the timer.
3) The timer cover (case), the knobs,
and the dials are made of polycarbonat-
ed resin. Therefore, prevent the timer
from being exposed to organic solvents
such as methyl alcohol, benzine, and
thinner, strong acid substances such as
12
(+55°C
+131°F
for the
caustic soda, and ammonia and avoid
using the timer in atmosphere containing
any of those substances.
4) If the timer is used where noises are
emitted frequently, separate the input
signal elements (such as a sensor), the
wiring for the input signal line, and the
timer as far as possible from the noise
source and the high power line contain-
ing noises.
8. Checking the actual load
In order to increase the reliability in the
actual use, check the quality of the timer
in the actual usage.
9. Others
1) If the timer is used exceeding the rat-
ings (operation voltage and control
capacity), the contact life, or any other
specified limit, abnormal heat, smoke, or
ignition may occur.
2) If any malfunction of the timer is likely
to affect human life and properties, give
allowance to the rated values and perfor-
mance values. In addition, take appro-
priate safety measures such as a duplex
circuit from the viewpoint of product lia-
bilities.
