Reliance 7000
Reliance · Model 7000
Dual side controls. Membrane switches and rotation locks control all operations of the chair from a sitting or standing position. Power base and top. Use finger switches or corded foot switch to raise, lower, or recline the chair. High and low base models available. Hydraulic base tested to 600 pounds. Auto return button returns the chair to the upright position. Memory Positioning Switch enables you to pre-select the chair's most used position. The Safety Switch prevents small children from operating the chair by disabling side and footswitches. Armrests lock in place. Release mechanism allows patients to sit or leave from either side of the chair. Padded underneath for comfort. CSA, C/US Certificate of Compliance. Full power articulating examination chair/minor procedure table with square base and dual controls for base and top functions, either by footswitch or membrane switches on both sides of chair back. Programmable memory feature for recline position and safety switch. Single lock adjustable concave headrest standard with choice of headrest to best fit your practice needs.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Chair will not raise / lower (hydraulic base fault)
HighSymptoms: No base movement from the foot switch or membrane switches, drifts down under load.
Root cause: Worn hydraulic pump / motor, internal cylinder seal leak, or a failed base actuator relay.
Back / recline actuator fault
MediumSymptoms: Back will not recline or return, moves on one side only, noisy actuator.
Root cause: Worn linear actuator, limit-switch fault, or a broken drive nut.
Membrane switch / control failure
MediumSymptoms: One or more functions dead from a control station, intermittent response, auto-return not working.
Root cause: Cracked membrane switch overlay, moisture ingress, or a control-board fault.
Safety switch / interlock defeated or failed
HighSymptoms: Side and foot switches remain live when the safety switch is set, or all controls dead.
Root cause: Failed safety switch or its wiring.
Armrest / release-mechanism wear
LowSymptoms: Armrest will not lock or release, excessive play, patient-access side drops.
Root cause: Worn latch and pivot hardware.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Chair will not lift
- Verify mains power and any e-stop / safety switch position.
- Try both the foot switch and the membrane switches - if all base control is dead, suspect the safety switch or control board.
- Listen for the hydraulic pump motor when lift is commanded; no sound points to the motor/relay, motor runs but no lift points to a seal leak.
- Check the base for hydraulic fluid weeping.
- Replace the pump/motor or reseal the cylinder as indicated, then load-test to the rated capacity.
Symptom: One control function not responding
- Test the same function from the other control station to isolate a membrane switch vs the actuator/board.
- Inspect the membrane overlay for cracks and the connector for moisture.
- Substitute a known-good foot switch if that is the affected input.
- Check the actuator's limit switches and wiring.
- Replace the failed switch or actuator and verify auto-return operation.
