• When mounting the Timer to a panel, tighten the two mounting
screws alternately, a little at a time, so as to keep them at an equal
tightness. If the panel screws are tightened unequally, water may
enter the panel.
• Store the Timer at the specified temperature.
If the Time has been stored at a temperature of less than -10°C,
allow the Timer to stand at room temperatu
re for at least 3 hours
before use.
• Mounting the Timer side-by-side may redu
ce the life expectancies
of internal components.
•
Use the Timer within the specified ranges for the ambient operating
temperature and humidity.
• Do n
ot use in the following locations:
• Locations subject to sudden or extreme changes in temperature.
• Locations subject to oil.
• Locations where high humidity may result in condensation.
• Locations prone to icing.
• Locations with excessive vibr
ation or shock.
• Locations subject to exposur
e chemicals.
•
Locations subject to water.
• Locations subject to bugs and small animals.
• Do not use this Timer in dusty envir
onments, in locations where
corrosive gasses are p
resent, or in locations subject to direct
sunlight.
• Install the Timer well away from any sources of static electr
icity,
such as pipes transporting
molding materials, powders, or liquids.
• Internal elements may be destroyed if a voltage outside the rated
voltage range is applied.
• Be sure tha
t polarity is correct when wiring the terminals.
• Separate the Timer from sources of noise, such as devices with
input signa
ls from power lines carrying noise, and wiring for
I/O
signals.
• Do not connect more than two crimp terminals to the same
ter
minal.
• Up to
two wires of the same size and type can be inserted into a
single ter
minals.
•
Use the specified wires for wiring.
Applicable Wires: AWG 18 to AWG 22, solid or
twisted, copper
Stripping length: 5 to 6 mm (recommended)
• Install a switch
or circuit breaker that allows the operator to
immedia
tely turn OFF the power, and label it to clearly indicate its
function.
• When the Timer is operated with no-voltage input (NPN input) for
models other th
an the H5CC-A11F, appro
ximately 14 V is output
from the input terminals. Use a sensor that contains a diode.
• Use a switch, relay, or other contact so that the rated power supply
voltage will be reached within
0.1 seconds. If the power supply
voltage is not reached quickly enough, the Timer may malfunction
or outputs may be unstable.
• Use a switch, relay, or other contact to turn the power supply OFF
instantaneously. Outputs may malfunction and memory error
s may
occur if the power supply voltage is decreased gradually.
H5CC-A@/-L@:
• When changing the set value during a timing operation, the output
will turn ON if the set value is changed as follow
s because of the
use of a constant read-
in system:
Elapsed time (UP) mode: Present value ≥ Set value
Remaining time (DOWN) mode: Elapsed time ≥
Set value (T
he
present value is set to 0.)
When in the remaining time mode, the amount the set value is
changed is added to or subtracted from the present
value.
Operation with a set value of 0 will vary with the output mode. Refer
to the timing charts.
H
5CC-AWSD:
• When changing the set value during a timing operation, the output
will turn ON if the set value is changed as follow
s because of the
use of a constant read-
in system:
1. Forecast Value Setting
When the present value ≥ the set value, OUT
2 (control output)
turns ON
. When the present value ≥ the forecast value (forecast
value = set value - forecast set value), OUT1 (forecast output)
turns ON.
2. Absolute Value Setting
When the present value ≥ set value 2, OUT2 (control output 2)
turns ON. When t
he present value ≥ the forecast value 1, OUT1
(control output 1) turns ON
. When the set value is 0, the output
turns ON the moment the signal is input. The reset operation
turns OFF the output. Refer to the timing charts.
• Do not use organic solvents (such as paint thinners or benzine),
strong alkali, or strong acids. They will damage th
e external finish.
• Confirm that indications are working normally, including the
backlight LED and LCD. The indicato
r LEDs, LCD, and resin parts
may deteriorate more quickly depending on the application
environment, preventing normal indications. Periodic inspection
and replacement are required.
• The waterproof packing may deteriorate, shrink, or harden
depending on the ap
plication environment. P
eriodic inspection and
replacement are required.
Precautions for Safe Use
It is recommended that the
space between the screw
head and the Adapter be 0.5
to 1 mm.
