Gardner Denver Electra Saver Error Code G006

Gardner Denver Compressor Critical Safety

Model: Electra Saver | Code: G006

Applicable Systems
Electra Saver

Symptoms

Emergency stop circuit has been broken. The red E-stop button is pressed, a guard door is open, or a safety interlock switch has failed open. All operations stop immediately.

Possible Causes

  • Operator or maintenance personnel pressed the emergency stop button
  • Belt guard or electrical cabinet door open, breaking the safety chain
  • Safety interlock switch contact failed open due to mechanical wear or broken actuator
  • Safety relay coil failure or wiring break in the control circuit

Troubleshooting Steps

  1. Step 1: Visually inspect all E-stop buttons and verify none are in the pressed/latched position
    Twist-release all mushroom buttons and confirm they spring back to the run position
  2. Step 2: Check all guard doors and access panels - ensure they are fully closed and latched
    Listen for the interlock switch click when each door is closed. Adjust actuator if no click is heard
  3. Step 3: Use a multimeter in continuity mode to test the safety chain from the first E-stop to the safety relay
    Isolate the break by sectioning the circuit at terminal blocks. Replace any failed switch or repair broken wiring
  4. Step 4: Test the safety relay by measuring coil voltage when the chain is complete
    Replace the relay if coil energizes but output contacts do not close

How to Reset

Reset: Release all E-stops, close all guards, and verify safety chain continuity. Press the green Start button. The compressor performs a 5-second pre-lube before loading.

Common Replacement Parts

  • GD-1050: Emergency stop button, twist-release (Red mushroom, 40 mm, NC contact, IP65)
  • GD-1051: Guard door interlock switch (Key-operated, NC, with actuator and bracket)
  • GD-1052: Safety relay, dual-channel (Force-guided contacts, 24V DC coil, ISO 13849 Category 3)

Frequently Asked Questions

  • Q: Why does the alarm return immediately after I press Start?

    This means the safety chain is still open. Common causes: a door not fully latched, a failed interlock switch, or a wire off a terminal. Trace the chain with a multimeter.

  • Q: Can I bypass the safety relay to test?

    Only for diagnostic multimeter testing. Never run the compressor with a bypassed safety circuit. It is a violation of OSHA lockout/tagout rules and factory safety policy.
