Hydraulic Pressure Alarm: Safe Diagnosis Notes

A hydraulic pressure alarm should be handled by qualified personnel because it may involve pressure demand, oil condition, oil temperature, filter condition, leakage, pump response, valve behavior, or movement load. The safe first step is to record where in the sequence the alarm appears.

Quick Answer

Record the alarm text, movement step, oil temperature or visible condition if available, and recent maintenance work. Do not continue production or adjust hydraulic components without qualified review.

What You May See

• The controller reports hydraulic pressure, oil pressure, or pressure-related alarm.
• Clamping, injection, table movement, or ejection stops under load.
• Movement becomes slow, weak, noisy, or inconsistent.
• Oil temperature, leakage, or visible contamination is suspected.
• The issue appears after maintenance, oil change, filter work, mold change, or parameter adjustment.

Likely Cause Areas

• Oil level, oil condition, oil temperature, or contamination may affect pressure response.
• Filter condition or flow restriction may affect hydraulic supply.
• Leakage, hose condition, seal condition, or connection issues may reduce pressure stability.
• Pump, valve, or control response may need qualified inspection.
• A movement step may require more force because of obstruction, mold setup, or mechanical resistance.
• Recent maintenance or setup changes may have introduced air, restriction, or incorrect condition.

Safe Checks Before Adjustment

Stop automatic operation if movement, alarm, guarding, or operator safety is uncertain. Do not place hands in the mold, table, injection, or guarded area while movement is possible. Use photos, controller screenshots, cycle logs, and safe observation before changing several settings.

Diagnosis Path

1. Stop automatic operation if movement or pressure behavior is abnormal.
2. Record the alarm screen, movement step, machine state, and time.
3. Check for visible leakage, unusual sound, oil temperature warning, or maintenance notes from a safe position.
4. Identify whether the alarm occurs during clamping, injection, table movement, ejection, or idle state.
5. Review recent oil, filter, hose, valve, mold, or maintenance work.
6. Ask qualified personnel to inspect oil condition, filter state, pressure response, and hydraulic components.
7. Compare the pressure alarm with part defects, cycle instability, or movement abnormalities.
8. Contact support if the alarm repeats or the cause is not visible after basic evidence collection.

Evidence to Collect

Check	Why It Matters	Evidence to Collect
Alarm timing	The movement step helps identify load and system demand	Alarm screenshot and sequence note
Oil and maintenance condition	Hydraulic behavior depends on oil and service state	Oil service record, filter notes, visible condition
Leakage or sound	Visible or audible symptoms may indicate mechanical review need	Safe photos and observations
Movement affected	Clamp, injection, table, and ejection alarms point to different loads	Cycle notes and safe video if available
Recent changes	Maintenance or mold changes often explain new alarms	Maintenance and setup records

What Not to Change Too Quickly

• Do not inspect pressurized hydraulic components unless qualified.
• Do not continue production if pressure behavior is abnormal.
• Do not treat a hydraulic alarm as only a controller reset issue.
• Do not ignore oil temperature, leakage, or unusual sound.

When to Contact Deboge

Contact Deboge when hydraulic pressure alarms repeat, affect movement, or appear after maintenance or mold change. Send alarm screenshots, movement step, oil and maintenance records, machine model, and safe video or photos if available.
