Alarm 1000 fires when the NGC control detects chip auger motor overload, proximity sensor timeout indicating no rotation, or loss of feedback from the auger drive circuit. The control monitors auger operation through parameter 800 (AUGER ENABLE) and related I/O signals to prevent motor or gearbox damage.

Haas Alarm 1000 - Chip Auger Error
Chip Auger
This alarm is triggered when the chip auger motor fails to start, overloads during operation, or the auger jam detection circuit signals excessive current draw to the IOCON board. The control monitors auger motor current and feedback signals to prevent damage to the auger gearbox and motor. On machines with auger enable input, this alarm can also occur if the chip cart is not in position or the interlock switch is open.
Root Cause Summary
Alarm 1000 fires when the NGC control detects chip auger motor overload, proximity sensor timeout indicating no rotation, or loss of feedback from the auger drive circuit. The control monitors auger operation through parameter 800 (AUGER ENABLE) and related I/O signals to prevent motor or gearbox damage.
Safety
Chips may accumulate
Causes and Fixes
1
Check Auger Housing
Navigate to CURRENT COMMANDS > MDI and jog machine to access auger. Visually inspect auger housing and discharge chute for chip jams or debris buildup.
Ensure spindle is stopped and machine is in E-STOP before inspection
2
Clear Obstruction
Remove any visible chip buildup or foreign objects from auger housing. Use shop air to blow out accumulated chips from auger flights and discharge area.
Check for long stringy chips that commonly wrap around auger flights
3
Test Auger Operation
Press CHIP FWD button on control panel to test auger rotation. Monitor for smooth operation and proper chip discharge.
Listen for unusual grinding or binding noises during operation
4
Reset Alarm
Press RESET button and verify alarm 1000 clears. If alarm persists, check parameter 800 (AUGER ENABLE) is set to 1.
Do not repeatedly attempt to run auger if alarm continues to occur
1
Locate Motor Overload Relay
Open electrical cabinet and locate the auger motor overload relay, typically mounted near the motor starter contactor.
Turn off main power and follow LOTO procedures before opening electrical cabinet
2
Check Relay Status
Examine overload relay for tripped condition (red button popped out or trip indicator visible). Check relay settings match motor nameplate amperage.
Overload relays should be set to 110-115% of motor nameplate current
3
Reset Overload Relay
Allow motor to cool for 10-15 minutes, then manually reset the overload relay by pressing the reset button until it clicks.
If relay trips immediately upon reset, do not continue - motor or circuit fault exists
4
Test and Monitor
Restore power and test auger operation using CHIP FWD button. Monitor motor current draw and listen for abnormal operation.
Use clamp-on ammeter to verify actual motor current is within nameplate specifications
1
Access Diagnostics
Navigate to SETTINGS > DIAGNOSTICS > INPUTS and locate the auger proximity sensor input (typically INPUT 20-25 range).
Sensor input should toggle ON/OFF when auger rotates manually
2
Check Sensor Signal
Manually rotate auger shaft while observing sensor input status on diagnostics screen. Input should toggle consistently with each auger flight passing the sensor.
Ensure auger motor is disconnected before manual rotation
3
Inspect Sensor Mounting
Check proximity sensor mounting bracket for looseness, proper gap (typically 1-3mm), and alignment with auger target or magnet.
Use feeler gauge to verify sensor gap - too close or too far will cause erratic operation
4
Test Sensor Continuity
With power off, check sensor wiring continuity from sensor to I/O board connection. Replace sensor if wiring is good but no signal present.
Use only Haas-approved proximity sensors to ensure proper voltage and timing specifications
1
Check Contactor Operation
Navigate to SETTINGS > DIAGNOSTICS > OUTPUTS and activate auger output while observing motor contactor. Contactor should pull in with audible click.
Observe contactor operation with electrical cabinet door open - follow electrical safety procedures
2
Verify Control Voltage
Measure 24VDC at contactor coil terminals when auger output is activated. Check for proper voltage and clean connections.
Voltage drop below 20VDC indicates wiring issues or control power supply problems
3
Test Motor Power
With contactor pulled in, measure 3-phase voltage at motor terminals. Should read line voltage (typically 230V or 460V) across all phases.
Use proper PPE and voltage-rated test equipment when measuring motor voltages
4
Replace Faulty Components
Replace contactor if coil energizes but contacts don't close, or if contact resistance is high. Check motor windings if contactor operation is normal.
Always replace contactor coil suppression diode when replacing contactor to prevent control damage
1
Verify Auger Parameters
Navigate to SETTINGS > PARAMETERS and check parameter 800 (AUGER ENABLE) is set to 1, and related timing parameters are within specification.
Parameter 801 (AUGER DELAY) should typically be set to 2-5 seconds
2
Check I/O Configuration
Verify auger-related inputs and outputs are properly configured in SETTINGS > DIAGNOSTICS. Compare with machine-specific I/O documentation.
Incorrect I/O mapping can cause control to monitor wrong signals
3
Review Alarm History
Check ALARMS > ALARM HISTORY for pattern of alarm 1000 occurrences. Note timing and frequency to identify intermittent issues.
Frequent alarms at startup may indicate timing parameter issues
4
Reset to Defaults
If parameters appear corrupted, restore auger-related parameters to factory defaults and reconfigure per machine specifications.
Document current parameter values before resetting in case restoration is needed
