Because of the structural nature of the B type, the temperature around the spear lowers earlier than that of the manifold when
the manifold and body heaters are stopped simultaneously, possibly causing breakage of the spear (tip bending).
Therefore, it is necessary to lower the manifold temperature first and then lower the body temperature. The delay off function
automatically conducts that operation.
(1) The manifold output is stopped and the body temperature remains at the heat-retention temperature.
(2) The temperature of all the manifold lowers below 100°C, or all heaters stop output when 30 minutes pass.

supply to the controller, and then remove the cover from the controller, otherwise an electric shock or
fire will result.
REFERENCE
MAINTENANCE
It is recommended to make a note of the connection destination and installation position in order to prevent incorrect wiring or
installation.
Air filter cleaning
The filter can be removed for cleaning.
≆ WARNING
When the controller with a clogged filter is used, the temperature inside the controller will rise, not only preventing the controller
from delivering its performance sufficiently but also causing breakage of the controller or fire.
Washing air filter with water
When the filter cannot be cleaned by a vacuum cleaner, it is possible to remove it and wash it with water. When the filter is
washed with water, drain the water sufficiently and dry the filter before installing it again.
Water remaining on the filter will cause trouble.
IMPORTANT
Clean the filter frequently when used in a dusty environment.
It is necessary to clean the air filter at the suction port at least every year.

Replacement of backlight of LCD touch panel
When the LCD touch panel blacks out and the LED in the lower left section of the LCD touch panel
comes on in orange (green when normal), the backlight has burned out.
When the LED comes on in
orange, the backlight has burned
out.
IMPORTANT
When the backlight burns out, the screen blacks out and the display becomes invisible. Since input on the touch panel is valid,
however, improper touch panel operation may result when the touch panel is touched confusing the situation with the backlight
off state.
REFERENCE
When the LED is lit in green while the backlight is off, the function that protects the display element of the LCD touch panel is
activated.
The backlight will go out automatically when the touch panel is not operated for five minutes.
The life of the backlight is approx. five years when used normally.
When the backlight burns out, it must be replaced with a new one. The type is PS300-BU00 (digital).

Cause
Correction
Imperfect contact of sensor connector
㨂㧼‒
Remove the junction cable from the controller, and check to see if the
connector pin has receded, causing imperfect contact.
Disconnection of sensor
Disconnection of junction cable
Measure the resistance on the junction cable side (mold side) with an
ohmmeter of a tester. When the needle points at infinity, the sensor,
junction cable, or connector box is out of order. Check it. (The
normal resistance is from several tens of Ω to several kΩ.)
Imperfect contact of spear sensor
When the condition is normal after inspection for “imperfect contact”
and “disconnection of sensor and junction cable,” it is possible that
disconnection sometimes occurs depending on the body temperature.

AHC controller is designed to sufficiently withstand the electromagnetic
noise within the industrial standard. When there is some equipment
generating noise in excess of the standard, measures are necessary to
cope with the noise of the equipment.

(1) If the manifold is short-circuited, select Manifold soft start to supply
power to the heater. When Manifold soft start is selected, power
is supplied at first with small output, and the situation will improve
in some cases.
(2) If the earth leakage breaker still trips after the procedure (1),
measure the insulation resistance of the heater, set (Disable) for
the manifold and probe with small resistance, and heat up the
damp heater.
(3) If the earth leakage breaker still trips after the procedure (2),
remove the fuse from the manifold and probe circuits with small
resistance, and heat up the damp heater, because the earth
leakage breaker may be tripped by the leakage current of the
SSR.
(4) If the problem is not solved after the procedure (3), dry the heater
with a dryer and then supply power to the heater.
