5.1 HSF-325 - Troubleshooting

Introduction

The toolholder’s bore and the cutting tool must be thoroughly cleaned (use a cleaning cloth/rag to clean) to prevent the cutting tool from getting stuck.

During the heating procedure, if alarms E1, E2, E3, E4, or E5 appear on the LCD Display Window see the Symptom Table below for more information.

NOTE: This induction shrink fit machine generates heat during use, and must be operated in a well ventilated area. The machine should be placed in a clean, dry location, and protected from strong hits. DO NOT attempt to service your machine! If you are experiencing issues, contact your local HFO for service.

NOTE: For safety purposes, keep flammable materials away from this machine while in use.

Symptom Table

Symptom Possible Cause Corrective Action
Error Code E1 Machine Heating Error Machine heating error.
Check the heating head connection.
Error Code E2 Heating Head Over Temperature Heating head over temperature. Allow a longer cooling period between heating tools.
The Heating Head Heat Sensor Failed Verify that the Heating Head isnt damaged. See the Heating Head Section below.
Error Code E3 3-Phase Power Supply Error 3-Phase incoming power is incorrect. Check incoming power wiring and phasing.
Error Code E4 No Toolholder in Heating Head No toolholder in heating head. Install a tool holder and lower the heating head to the correct height.
The CT2 Current Sensor 2 has failed. See the CT2 Current Sensor 2 section below.
The heating head height is not correct. See the HSF-325 Operation for more information.
Error Code E5 Machine Power Module Over Temperature Machine’s power module is over temperature. Allow a longer cooling period between heating toolholders.
CF1 Cooling Fan is not running. Check that the CF1 Cooling Fan runs when powered on.
Heating period too long. Only heat the tool long enough to install or remove and extend the cooling period if needed.
The IGBT Overheat Detect PCB failed. Verify that the IGBT Overheat Detect PCB isnt damaged. See IGBT Overheat Detect PCB section below.
Error Code E1 in Auto Mode and E4 in Manual Mode. The CT2 Sensor, GTS9000-4 PCB, or heating head failed. Verify a toolholder is installed. Check that the heating head is connected correctly. Check that the heating head height is set correctly. Verify that the CT2 Current Sensor 2 isnt damaged. If Error Codes continue to generate, replace CT2 - Current Sensor 2 with PN: 93-3340. If the Error Codes continue, replace 93-3568 GTS9000-4 PCB. Order PN: 93-3733 THERMAL PAD 4.8X2.4 RoHS W/4 MNTNG HOL when replacing GTS9000-4 PCB. If Error Codes continue to generate, replace the Heating Head assembly with PN: 93-3346.

GTS9000-5 PCB - IGBT OVERHEAT DETECT PCB Replacement

If the Error Code E5 is generated at power up. Troubleshoot that the GTS9000-4 PCB WITH IGBT MODULE is functioning. Install a toolholder and lower the heating head to the correct height. Navigate to Manual Function and press the manual heating button on the heating head to see if the GTS9000-4 PCB WITH IGBT MODULE functions. If the toolholder is heated then the GTS9000-5 PCB needs to be inspected. This is the IGBT Overheat Detection and may have failed.

Use a xacto knife to cut the hot glue on the ferrite filter and unplug the cable[1] from GTS9000-5 PCB to the GTS9000-2 PCB.

Use a xacto knife to cut the hot glue on the connector[2] on GTS9000-5 PCB and unplug the cable.

Remove the standoff nut[3] and replace the PCB. Transfer the ferrite filter from the failed PCB to the replacement PCB.

Apply hot glue to the ferrite filter to secure it in place and the connector on GTS9000-5 PCB.

CT2 - Current Sensor 2 Replacement

If the Error Code E4 is generated when a tool is heated. Verify a toolholder is installed. Check that the heating head height is set correctly. Verify that the CT2 Current Sensor 2 isnt damaged. If Error Code E4 continues to generate, replace CT2 - Current Sensor 2 with PN: 93-3340.

Remove the zipties from the ferrite filter[1], cable harness[2], and current sensor[3].

Unplug the cable[4] from GTS9000-1 PCB - PANEL CONTROL PCB WITH LCD MODULE.

Remove the ferrite filter from the cable harness[1].

Remove the cable[2] from the BD - 3 PHASE RECTIFIER.

Use a pick to remove the red and orange cable from the connector[3].

Insert the red and yellow cable from the replacement CT2 - Current Sensor into the connector in the correct pinout[4].

Feed the cable through the CT2 - Current Sensor and secure to the BD - 3 PHASE RECTIFIER.

Reinstall the ferrite filter to the cable harness.

Replace the zipties to secure the ferrite filter, cable harness and CT2 - Current Sensor 2.

Heating Head Replacement

If the Error Code E2 is generated when selecting Auto Mode or without heating the tool. Error code E1 in auto mode and E4 in manual mode and the CT2 Sensor and GTS9000-4 IGBT Module has been replaced. Troubleshoot and visually inspect that the Heating Head Overheat Sensor has not failed or is damaged. Replace the failed Heat Head with PN: 93-3346.

Disconnect the heating head cables and air line and remove the heating head from the guide rail.

Install the heating head assembly and connect the heating head cables and air line.

GTS9000-4 PCB Replacement

If Error Code E1 is generated when the tool is heated in Automatic Mode or Error Code E4 is generated when a tool is heated in Manual Mode. Verify a toolholder is installed. Check that the heating head is connected correctly. Check that the heating head height is set correctly. Verify that the CT2 Current Sensor 2 isnt damaged. If Error Codes continue to generate, replace CT2 - Current Sensor 2 with PN: 93-3340. If the Error Codes continue, replace 93-3568 GTS9000-4 PCB. Order PN: 93-3733 THERMAL PAD 4.8X2.4 RoHS W/4 MNTNG HOL when replacing GTS9000-4 PCB. If Error Codes continue to generate, replace the Heating Head assembly with PN: 93-3346.
