What This Guide Helps With

Error: PLUGS MAINS indicating battery voltage below 19V, preventing normal table operation due to insufficient power.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• If the table is in use, safely stop movement and ensure the patient is stable
• If positioning is limited, transfer the patient to another table if needed

Verify the Reported Error and Behavior

• Power on the table and confirm “PLUGS MAINS” is displayed
• Observe when the error appears (startup or during movement)
• Check if table functions are limited or disabled
• Review battery indicator status if available

Connect Table to Mains Power

• Plug into a known working wall outlet
• Ensure power cord is fully seated at both ends
• Verify outlet functionality using another device
• Confirm power switch is ON and indicator is green

Inspect Power Cord and Connections

• Check for fraying, cuts, or bent prongs
• Ensure connections are secure and not loose
• Reseat the power cord firmly

Allow Battery to Charge and Recheck

• Leave the unit plugged in for several minutes
• Observe if the error clears after charging begins
• Test basic table movement after partial charge

Check Power Indicator Behavior

• Confirm steady green light when plugged in
• Note if the light is off, flickering, or abnormal

If the Problem Persists

If external causes such as outlet, cord, and charging time have been ruled out, the issue likely involves internal power components.

• Remove the device from service
• Label the unit Out of Service
• Send for repair or bench evaluation

Clinical Use Tip

Never troubleshoot a surgical table while a patient is on it. Always transfer the patient to a safe, functioning device before addressing power-related issues.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Unit displaying PLUGS MAINS error and unable to perform full positioning functions."

Cause

What was observed during troubleshooting.

Example:
"Battery voltage below operational threshold; table not connected to mains power or battery discharged."

Resolution

What action was taken.

Example:
"Connected unit to verified outlet, confirmed power indicator, allowed charging, and restored normal operation."

Helpful Details to Include (If Known)

• Alarm behavior
• Accessories swapped
• Power behavior
• Environmental factors
• Indicator lights
• Final device status

Final Thought

Low battery voltage errors are often caused by simple external power issues. Always verify power sources first before escalating. If charging does not resolve the issue, internal components may require service.

That is successful troubleshooting.
