2. Application Worksite Checklist

Engineered with corrosion-resistant housing and sealed internal core, to withstand harsh hydraulic system conditions:

• Hydraulic Pressure Monitoring: Provides accurate pressure on/off signal to machine controller for hydraulic system control.
• Heavy Earthmoving & Quarry Operations: Wear-resistant housing resists hydraulic oil corrosion, dust and vibration under continuous heavy-load operation.
• Long-Hour Mining & Loading Work: Stable switch action prevents hydraulic system fault codes during multi-shift operation.
• Hydraulic System Protection: Reliable pressure trigger signal helps protect hydraulic pumps and valves from overload damage.

3. Pressure Switch Troubleshooting & Diagnostic Guide

If your PC200-8 machinery hydraulic system is exhibiting switch-related failure, consult the diagnostic guide below:

• Fault 1: No Pressure Signal on Machine Dashboard
  Root Cause: Failed or intermittent pressure switch — Controller receives no pressure trigger signal.
  Solution: Replace with new PC200-8 pressure switch and inspect connector pins.
• Fault 2: Hydraulic Power Loss & Unstable Operation
  Root Cause: Incorrect pressure signal makes controller misjudge hydraulic system status.
  Solution: Install new PC200-8 pressure switch and check wiring connector.
• Fault 3: Hydraulic System Related Fault Code
  Root Cause: Open circuit, short circuit or corroded switch connector.
  Solution: Replace PC200-8 pressure switch and clean connector terminals; clear DTC with diagnostic scanner.
• Fault 4: Machine Hydraulic Function Not Responding
  Root Cause: Missing pressure signal leads controller to miscontrol hydraulic components.
  Solution: Replace the PC200-8 pressure switch before pursuing expensive hydraulic system repairs.
• Fault 5: Switch Internal Damage from High Vibration
  Root Cause: Long time heavy vibration causes internal switch element damage.
  Solution: Replace switch, check mounting bracket and tighten fixing bolts properly.
