Description

 

🔹 Product Introduction

The OMNI FLOW COMPUTERS 68-6002 is an operator interface/front panel assembly associated with Omni Flow Computers flow measurement and flow computer equipment. Available industrial spare-part references identify 68-6002 as an Operator Interface and also as a Front Screen Board / NCI-3 Front Panel Screen Board.

The unit is designed to provide the operator-facing interface for compatible Omni Flow equipment, allowing personnel to view operating information and interact with the flow computer system.

The 68-6002 is a legacy industrial instrumentation component. It should be treated as a system-specific replacement part rather than a universal HMI panel. Compatibility should be confirmed against the complete Omni Flow Computer model, board revision, connectors, and installed front-panel configuration before replacement.

🔍 Compare the front-panel layout.

🔍 Check connector locations.

🔍 Compare mounting points.

🔍 Check PCB revision and markings.

🔍 Verify any attached interface boards.

3. Shut Down the Equipment

Place the flow computer in the approved maintenance condition. If the equipment is controlling or monitoring an operating process, follow the site’s process-instrumentation shutdown procedure.

4. Remove the Existing Panel

Disconnect power and interface wiring only after confirming that the equipment is electrically safe.

Record connector positions before removing the original front panel.

5. Install the 68-6002

Mount the replacement panel in the original position. Secure the assembly without applying excessive mechanical force to the PCB or display.

6. Reconnect Interfaces

Reconnect cables according to the original configuration. Check that connectors are fully seated.

7. Restore Power

Apply power according to the host Omni Flow Computer’s approved startup procedure.

8. Verify Operation

Check the display, operator controls, system status, flow values, alarms, and communication with the flow computer.

 

⚡ Power-On Sequence

1. 🔒 Place the flow computer in a safe maintenance state.
2. 🔍 Verify the 68-6002 installation.
3. 🔌 Check all front-panel connectors.
4. 🔍 Confirm correct wiring and grounding.
5. ⚡ Apply the specified system power.
6. 🖥️ Allow the flow computer and front interface to initialize.
7. 🔍 Check the display for abnormal indications.
8. ⌨️ Test available operator controls.
9. 📊 Verify displayed flow and process values.
10. ⚠️ Check alarm/status indications.
11. 🌐 Verify communication with associated instrumentation where applicable.
12. ✅ Return the system to service after successful testing.

 

🔌 Power-Off Sequence

1. 🛑 Place the flow computer in the approved maintenance condition.
2. 📢 Notify the responsible operations/instrumentation personnel.
3. 💾 Record required configuration and process information.
4. 📴 Shut down the host flow computer normally where applicable.
5. ⚡ Isolate the electrical supply.
6. 🔍 Verify the panel is de-energized.
7. 🔧 Disconnect the front-panel cables.
8. 🛡️ Use ESD protection when handling the PCB.

⚠️ Do not remove the front-panel assembly from energized equipment unless the manufacturer’s service procedure specifically allows it.

 

📖 Product Usage Instructions

The 68-6002 is intended to operate as part of a compatible Omni Flow Computer system.

It should not be treated like a standalone PLC HMI. The panel’s operation depends on the host flow computer, internal electronics, firmware, interface boards, and installed instrumentation configuration.

During replacement, preserve the original cable arrangement and configuration. Photograph the existing panel before removal and record all connector positions.

After startup, verify that the front panel correctly displays the process values generated by the flow computer. Check alarm and status information before returning the equipment to normal operation.

The 68-6002 is also referenced in the market as 21129-002D, so this number may be useful when cross-checking an existing assembly or spare-parts record.

 

🔍 Inspection & Maintenance

Before installation:

• Verify the model number 68-6002.

• Check the front-panel face for cracks or damage.

• Inspect the display/window for scratches or clouding.

• Check buttons, keys, switches, or controls for mechanical damage.

• Inspect PCB connectors for oxidation.

• Check the PCB for corrosion or burned components.

• Compare the replacement board revision with the original.

• Check all cables before reconnection.

• Confirm compatibility with the host Omni Flow Computer.

• Perform a functional test after installation.
