What This Guide Helps With
Error: VOLTAGE PEAK indicating battery voltage exceeding 31V, creating an overvoltage condition that can lead to electrical instability, unpredictable table behavior, or system shutdown.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Immediately remove the table from active patient use
- If in a procedure, safely transfer the patient to another stable surface
- Ensure no movement functions are actively engaged
2. Verify the Reported Error and Behavior
- Power on the table and confirm “VOLTAGE PEAK” is displayed
- Observe when the error occurs (startup, charging, or operation)
- Attempt basic table functions if safe
3. Check Power Source and Charging Conditions
- Verify the table is connected to a known good outlet
- Inspect the power cord for damage or loose connections
- Disconnect from mains and operate briefly on battery (if safe)
4. Inspect Battery Condition (External Only)
- Check for swelling, heat, or leakage
- Listen for unusual sounds
- Check for burning odor
5. Power Cycle the System
- Turn the table OFF
- Disconnect from mains power
- Wait 60 seconds
- Reconnect and power ON
6. Isolate Charging vs Internal Regulation Issue
- Operate the table on battery only
- Reconnect to mains and monitor for error return
- Determine if error occurs only during charging or at all times
7. Stop if Issue is Resolved
- If the error clears and does not return, return the table to service
- Monitor closely during initial use
If the Problem Persists
External causes have been ruled out. Persistent VOLTAGE PEAK error indicates an internal power regulation failure.
- Remove the device from service
- Label the device as Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot or continue using a surgical table with electrical instability on an active patient. Always transfer the patient to a backup device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Table displaying VOLTAGE PEAK error; unit not trusted for use due to overvoltage condition."
Cause
What was observed during troubleshooting.
Example:
"Battery voltage exceeding safe threshold (>31V), indicating likely internal power supply failure after external checks."
Resolution
What action was taken.
Example:
"Verified power source, inspected connections, performed power cycle, and isolated issue. Removed from service and sent for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Voltage-related errors should always be treated as high-risk conditions. Proper troubleshooting means ruling out simple causes first, then confidently escalating when internal faults are indicated.
That is successful troubleshooting.
