1 Troubleshooting

This appendix describes problems that may occur during use of the SJ-M Series and how to remedy

them. Check the following table before sending in your SJ-M Series for repair.

Symptom Check Item Remedy

No indication on ion

monitor

Is the power cable connected

properly?

Connect the power cable correctly.

Is a power supply within

specification being used?

Use a power supply that is within

specification.

Static elimination is

not performed.

Is the electrode probe worn or dirty?

Perform maintenance on the electrode probe

or replace the Electrode Unit.

Is high temperature use set?

When the power is turned ON for the first

time, or a different model of Static Elimination

Head is installed, perform the “High

temperature use setting.”

"High temperature use setting" (page 8)

Is static elimination stop currently

set?

Cancel static elimination stop input on the

SJ-M Series.

Is the abnormal discharge detection

function operating?

Check the Electrode Unit for any conductive

substances (e.g. oil droplets).

Static elimination is

not performed

properly.

Are conductors or other static

eliminators located near this Static

Eliminator?

Move the Static Eliminator away from

conductors or other static eliminators nearby.

The ion level alarm is

output/indicated.

Is the electrode probe worn or dirty?

Perform maintenance on the electrode

probes or replace the Electrode Unit.

Are conductive objects located in

the surrounding area?

Check the installation location.

"Installation site" (page 5)

The condition alarm is

output/indicated.

Are static elimination target objects

having a very high charged level

located near the Static Eliminators?

Increase the number of connected static

eliminators.

Is the electrode probe worn or dirty?

Perform maintenance on the electrode

probes or replace the Electrode Unit.

The alarm indicator

lights.

–

Check “During an alarm (levels 1, 2)”

( page 15) in this Instruction Manual.

Control output is not

output correctly.

Is output wired correctly?

Check the output circuit and wiring, and

Check "Table of Indicated States" ( page

14) in this Instruction Manual.

2 Table of Indicated States

This appendix describes the various indicated states of the SJ-M Series.

■ Indicated state when the power is turned ON

■ Indicated states when the power is turned ON for the first time or when a

different model Static Elimination Head is connected

Lit State Description

The state (charged level indication or ion

level indication) that was active before the

power was turned OFF is displayed.

At the same time, the alarm indicator, ion

level alarm indicator, and condition alarm

indicator light (red).

The ion monitor LEDs fluctuate upward

and downward.

When the power is turned ON, the indicated state (charged level

indication or ion level indication) that was active before the

power was turned OFF is displayed. Also, the alarm indicator,

ion level alarm indicator and condition alarm indicator light (red)

at the same time. After this indication state continues for about

two seconds, the ion monitor LEDs fluctuate upward and

downward, and static elimination is then started. After static

elimination starts, the charged level or ion level is indicated.

Lit State Description

When the power is turned ON for the first time after purchase,

the SJ-M Series starts up at the “High temperature use setting”

in the Setup mode. At this time, static elimination is not

performed.

For details on setting items and how to set up setting items, see

the following:

"High temperature use setting" (page 8)

Make the settings match the actual operat-

ing environment. Incorrect settings may

cause accidents or malfunction.

Blink alternately at high speed
