operating output “RUN OUT” does not turn ON during
programming. The operation output turns ON with the timing shown in
the
diagram, but it remains OFF when an error occurs. Thus, you can use the output as a timing signal
during operation, including
test
runs.

After
turning on the power
, it takes approximately two seconds until

operation,
When
the ON angle and OFF angle are the same value, no output

Handling
Turn the operation power on or off instantaneously via a contact
such as a switch or relay.
A
void operation in the following environments:
1.
An ambient temperature below –10
°
C or above 55
°C.
2. Very dusty locations.
3. V
ery humid locations.
4.
Locations where corrosive gasses are generated.
5.
Locations with heavy vibrations or shock.
6.
Locations prone to water or oil.
7.
Locations with direct sunlight.
For
operation in environments
with excessive electrical noise gen
-
eration,
separate the
Encoder cords and the main unit of the H8PS
from high-power cables that have noise or noise-generating
sources.
The
external finish of the main unit is prone to organic solvents (thin
-
ner
, benzene, etc.), strong alkali (ammonia, sodium hydroxide), and
strong
acid. Please avoid contact with theses chemicals.
Store the devices between –25°C and 65°C. For storage below
–10°C,
power the unit up after letting it stand at room temperature
for three hours.
To perform dielectric testing, impulse-voltage testing, and insula-
tion-resistance measuring between the electrical circuitry and the
uncharged
metal parts when the unit is
mounted in a control panel,
first disconnect the wiring of the unit from the circuitry. (This pre-
vents degradation of damage of internal circuitry in the event that
part
of the control-panel equipment has faulty voltage resistance or
faulty
insulation. The test voltage might
go to the power-supply ter
-
minals
of the main unit.)
The
Encoder consists
of precision parts. Exercise care in handling,
and
make sure no excessive shock or pressure
is applied to the En
-
coder.
Especially make sure that the Encoder
’
s rotating shaft is not
subjected to excessive force.
The
connections for the main unit connectors should have no undue
stress
applied. Wire cables accordingly
.
Angle Data Table
The
H8PS uses an absolute Encoder with 256 divisions per revolu
-
tion.
T
o assist with programming, displays and settings may be done
by conversion to 360 degrees by a switch on the front panel. The
following
table shows the conversions.

WARNING
1. The
H8PS has a built-in lithium battery
.
Be sure to dispose of
the old H8PS properly, as lithium batteries are likely to
explode
if incinerated.
2. Electrical shock hazard
Never
touch the input terminals of any H8PS Cam Positioner
when
power is being applied to the Cam Positioner
.

Rotary Encoder
Make
sure that the E6CP Encoder is not subjected to oil or water
. If
oil or water enters the interior, malfunctions may occur. For use in
environments
subject to water drops or oil, use the E6F
.
Rotary
Encoders consist of precision parts. Their
operation may be
damaged
if the Encoder is dropped. Be very careful with handling.
When joining to a chain, timing belt, or gears, interpose a coupling
and
bearings before the Encoder
.
Large
mounting deviations (eccentric centers or
angles) may cause
an excessive load on the Encoder’s shaft, resulting in damage or
drastically reduced life expectancy. Take care not to place exces-
sive
loads on the shaft.
Keep the tightening torque around 5 kg S cm when fastening the
rotary
Encoder
.
Do
not pull the wiring at a force greater than 3 kg when the main unit
is
fastened and wired.
If
you insert a coupling on the shaft, do not hammer on the coupling
or
otherwise subject it to shock.
Mounting Procedure
1. Place
a coupling on the shaft.
Do not screw the coupling and shaft tight.
2.
Fasten the Encoder
.
Do not insert the shaft to the coupling more than the length
shown
