Is wiring correct?
Is wiring correct?
Connect the AC adaptor and the I/O
cable correctly.
Use a power supply that is within
specification.
To use a 24 VDC power supply, use a
DC power supply with enough capacity.
Turn on static elimination by following
the instructions of "Starting and
Stopping Static Elimination" (page 5).
Perform maintenance on the electrode
needles or replace the electrode unit.
"Performing Maintenance on the
Electrode Needles" (page 7).
Cancel the static elimination stop input
of the SJ-F031/036.
Check the electrode unit for any
conductive substances (e.g. oil droplets).
Keep the Static Elimination Blower away from
conductors or other Static Elimination Blowers.
Refer to "Adjusting Blow Rate of the
Static Elimination Blower" (page 5).
Clean the clogging duct and refuse off
the filter.
"Performing Maintenance on the Air
Filter" (page 7).
Perform maintenance on the electrode
needles or replace the electrode unit.
Keep the conductive objects away from the area
within 50 mm in front of the electrode needles.
Keep the Static Elimination Blower away from
conductors or other Static Elimination Blowers.
Perform maintenance on the electrode
needles or replace the electrode unit
Refer to "During an alarm
(levels 1, 2)" (page 9).
Check the output circuit and wiring,
and connect correctly.
Check the input circuit and wiring, and
connect correctly.
6-2 Table of Indicated States
This appendix describes the various indicated states of the SJ-F031/036.
■ Indicated states when the power is turned ON
■ Indicated states during setting change, confirmation and operation
(excluding when the power is turned ON)
Lit State Description
After the center LED of the monitor lit in red, the
state that was active before the power was turned
OFF is displayed. (charge monitor, ion level
monitor or blow rate setup monitor)
After the center LED of the monitor lights in red,
static elimination is performed with the display of
the state that was active before the power was
turned off, such as the charge monitor, ion level
monitor or blow rate setup monitor.
Two monitor LEDs on the + side and - side,
respectively, and the ion level indicator light in red.
One monitor LED and the blow rate indicator light in red.
Ion level monitor display
This displays the amount of ions that are being
emitted by the SJ-F031/036.
This displays the setting value of the blow rate of
the Static Elimination Blower.
The center LED of the monitor lights in red. Static elimination stop input (I/O terminal section)
The center LED of the monitor lights in red when
static elimination is turned off by shorting the static
elimination stop input wire and the 0 V wire.
Static elimination stop input (Operation panel)
The center LED of the monitor lights in red when
static elimination is stopped by pressing for
about two seconds.
One monitor LED and the ion balance indicator
light in red.
Charge monitor display
This displays the charged level of the target
object. When there is a plus charged object, the
LED on the + side lights, and when there is a
minus charged object, the LED on the - side lights
to indicate the charged level.
Lit State Description
6-2 Table of Indicated States
Lit State Description
Ion balance manual setup
In ion balance manual setup, press and hold or
000 to set the zero point.
The position of the LED that is lit up moves with
the cursor to light up the center LED.
Refer to "Adjusting Ion Balance" (page 5) for
details about how to start ion balance manual
setup.
One of the monitor LEDs lights.
Ion level alarm indicator blinks in red.
Ion level alarm
The ion level alarm indicator blinks in red when the
ion level decreases lower than the setting value.
Ion balance indicator blinks in red.
Ion balance manual setup start
Pressing and holding for about two seconds
while the ion balance indicator lights up starts ion
balance manual setup, when the ion balance
indicator starts blinking in red.
Condition alarm indicator blinks in red. Condition alarm
The condition alarm indicator blinks in red when
the ion balance is unstable due to influence of the
installation environment.
The state (charge monitor, ion level monitor or
blow rate setup monitor) that was active before
static elimination was turned OFF is displayed.
Static elimination stop input canceling
(Operation/Display section)
Pressing and holding for about two seconds
after static elimination is turned off using
cancels the static elimination stop input. The state
(charge monitor, ion level monitor or blow rate
setup monitor) that was active before the static
elimination was stopped is restored.
Note that when an alarm condition occurs, the
LED blinks to indicate the cause of the alarm.
Refer to "During an alarm (levels 1, 2)"
(page 9) for indicated states during an alarm.
