Product Overview

The GE IC697ACC720 Blank Slot Filler is a mechanical protection component used in compatible GE industrial control and PLC rack assemblies. Its primary function is to cover an unused module position in a control rack, helping maintain a clean and protected rack configuration while preventing accidental exposure of an unused slot.

Blank slot fillers are useful in industrial automation systems because unused rack positions can otherwise leave openings that expose internal areas to dust, foreign objects, accidental contact, and mechanical damage. A properly fitted filler also helps maintain consistent cabinet organization and can improve the overall serviceability of the PLC installation.

The supplied dimensions of the GE IC697ACC720 are 120 × 60 × 40 mm, with a listed weight of 0.3 kg. Its compact mechanical design allows it to occupy an unused rack position without requiring an active electrical function.

Product Identification

Technical Specifications

What Is a Blank Slot Filler?

A blank slot filler is a non-functional mechanical component installed in an unused rack position.

A PLC rack may contain several module positions, but not every position needs to be populated in every system configuration.

For example:

PLC Rack

• CPU Module
• Power Supply
• Communication Module
• Digital I/O Module
• Unused Slot → IC697ACC720
• Analog I/O Module

The filler occupies the unused position and provides a finished mechanical surface.

It does not replace an active PLC module and should not be treated as an electrical I/O component.

Main Functions

Unused Slot Protection

Covers an empty rack position and helps prevent accidental access to exposed internal areas.

Mechanical Protection

Reduces the possibility of foreign objects entering through an unused module opening.

Cabinet Organization

Maintains a consistent and professional rack arrangement.

Maintenance Safety

A covered unused position reduces the chance of accidental contact with internal rack areas during routine cabinet maintenance.

Typical Industrial Applications

The GE IC697ACC720 can be useful in industrial control systems where the rack configuration contains unused module positions.

Installation Guide

1. Verify the Rack Configuration

Before installation, identify the unused rack position.

Confirm:

• Correct rack
• Correct slot
• No active module is required in that position
• Filler dimensions are suitable
• Mechanical mounting arrangement is compatible

2. Shut Down the Equipment

Although the filler itself has no electrical function, installation should normally be performed during an appropriate maintenance shutdown.

Before working on the rack:

1. Stop the controlled process.
2. Follow plant safety procedures.
3. Isolate power when required.
4. Verify the equipment is safe to access.

3. Inspect the Empty Slot

Inspect the unused slot for:

• Dust
• Foreign objects
• Mechanical damage
• Bent mounting components
• Damaged rack surfaces

Clean the area if necessary using an appropriate maintenance procedure.

4. Inspect the Blank Slot Filler

Before installation inspect the IC697ACC720 for:

• Cracks
• Deformation
• Damaged mounting points
• Loose hardware
• Contamination

Do not install a damaged filler.

5. Install the Filler

Align the filler with the unused rack position.

Carefully insert or mount it according to the compatible rack arrangement.

Verify:

• Correct orientation
• Full engagement
• Secure mounting
• No interference with adjacent modules

The supplied dimensions are:

120 × 60 × 40 mm

The supplied weight is:

0.3 kg

6. Check Adjacent Modules

After installation, verify that the filler does not interfere with:

• Adjacent module handles
• Wiring
• Ventilation paths
• Rack mounting hardware
• Cabinet doors

7. Restore the System

After completing installation:

1. Perform a visual inspection.
2. Confirm all modules are secure.
3. Restore system power where applicable.
4. Monitor the controller for normal operation.

Because the filler is a passive mechanical component, it should not introduce an electrical configuration change by itself.

8. Verify the Completed Rack

Confirm:

• Unused slot is fully covered
• Filler is secure
• Adjacent modules remain properly seated
• No cables are obstructed
• Cabinet airflow remains appropriate

Troubleshooting Guide

Blank Slot Filler Does Not Fit

Possible causes include:

• Incorrect model
• Incorrect orientation
• Rack mismatch
• Damaged mounting points
• Foreign material inside the slot

Verify the filler model and rack configuration before applying force.

Filler Is Loose

Possible causes include:

• Improper installation
• Damaged mounting hardware
• Worn rack mounting point
• Incorrect positioning

Remove and reinstall the filler, then inspect the mounting mechanism.

Filler Falls Out During Maintenance

Possible causes include:

• Insufficient mechanical retention
• Damaged mounting components
• Excessive cabinet vibration
• Incorrect installation

Inspect the rack and filler before reinstalling.

Visible Cracks or Deformation

A damaged filler may no longer adequately protect the unused rack position.

Replace it if:

• Housing is cracked
• Mounting points are broken
• Component is significantly deformed
• It cannot remain securely installed

Dust Accumulation Around the Slot

Possible causes include:

• Poor cabinet sealing
• Excessive dust
• Damaged cabinet enclosure
• Open or improperly covered rack position

Clean the cabinet and address the environmental cause rather than relying solely on the filler.

Cabinet Temperature Increases

The filler itself is not an active cooling device. If cabinet temperature increases after installation, inspect:

• Cabinet ventilation
• Cooling fans
• Air filters
• Adjacent equipment
• Internal airflow

Do not modify the filler to create openings unless specifically required by the system design.

Preventive Maintenance

Monthly Inspection

Check:

• Filler position
• Mechanical condition
• Cabinet cleanliness
• Adjacent module condition

Quarterly Inspection

Inspect:

• Mounting security
• Rack condition
• Dust accumulation
• Cabinet vibration

Annual Maintenance

Perform:

• Complete rack inspection
• Cabinet cleaning
• Mechanical mounting inspection
• Environmental condition review

Why use a blank slot filler?

It helps protect an unused rack position from dust, foreign objects, accidental contact, and unnecessary exposure.

Can the filler be installed in any unused PLC slot?

Not necessarily. The filler should be mechanically compatible with the specific rack and slot arrangement.

Can a filler replace an active PLC module?

No. A blank slot filler does not provide processing, I/O, communication, or power functions.

Does the filler affect PLC configuration?

Because it is a passive mechanical component, it does not provide an active electrical function. However, the rack configuration should still be checked to ensure the unused slot is intentionally unpopulated.
