Key tips
- ·Verify true laser output with an external power meter, not the console readout - the display drifts independently of real delivered energy.
- ·Never bypass a door interlock, key switch, or footswitch safety to finish a treatment - laser safety interlocks are not optional.
- ·Most low-output complaints trace to the delivery fiber or handpiece, not the laser source - inspect and swap those first.
- ·Intermittent mid-treatment shutdowns are usually cooling-related - check coolant level and flow before suspecting the diode or lamp.
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.
No or low laser output
HighSymptoms: Weak or no output at the delivery device, treatment ineffective, power not reaching the set value.
Root cause: Laser module / lamp aging, a damaged delivery fibre / handpiece / applicator, or a driver / power-supply fault.
Cooling / thermal shutdown
HighSymptoms: Unit shuts down after a period, over-temperature or low-flow alarm.
Root cause: Chiller / TEC fault, low coolant, or blocked airflow.
Delivery fibre / handpiece / applicator fault
MediumSymptoms: Burn marks at the tip, high loss, intermittent output, applicator not recognised.
Root cause: Damaged or contaminated fibre / applicator / connector.
Contact-cooling / skin-cooling fault (aesthetic)
MediumSymptoms: Skin cooling not delivered, cooling alarm.
Root cause: Cryogen / contact-cooling supply, valve, or the tip.
Footswitch / interlock fault
MediumSymptoms: Laser will not fire, key / interlock / footswitch error.
Root cause: Footswitch, door interlock, or key-switch fault.

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.
- ·Laser output power verification against a calibrated external power meter
- ·Cooling-system check: coolant level, flow rate, and filter / heat-exchanger condition
- ·Delivery-system inspection: handpiece, delivery fiber or articulated arm, and output optics
- ·Interlock, key-switch, emergency-stop, and footswitch function test
- ·Beam-alignment and optical-path check per the service manual
- ·Annual full PM and electrical safety test
Error Codes
Extracted directly from this unit's own service manual.
Interlock Not ConnectedDisconnected Interlock Check status at rear connection connect interlock if necessary.
Check wiring on interlock plug or interlock connector.
Broken flash lamp/electrical problemReplace Handpiece and check if system works properly, if yes send the faulty handpiece for repair at factory, if system does not work replace switching module.
Leakage Error Electrical ProblemReplace SWMDL Charge Time Limit Power supply miss function
Do Charge discharge test and verify values reading on DVM and VMon of the system to match VProg ± 3VDC. If not try recalibrating VProgPar and/or VMonPar on Tech3 screen. If recalibration the parameters did not help replace capacitor Charger.
Vcap>30Dump board miss function
Do Charge discharge test and verify values reading on DVM and VMon of the system to match VProg ± 3VDC. If not OK replace Dump card or Dump contactor.
FlowSW ErrorNo water flow
Check water level Check position of flow switch Check water pump Check 24VDC power supply
FlowSW Off ErrorFlow switch stuck on top at system start.
Replace Flow Switch
Level Switch ErrorWater Level Low
Add Water
Thermal Switch ErrorWater Temp too high
System start immediately after error occurs? If Yes – Replace Thermal switch. If Not - Check room temperature between 20°C - 25°C, advice customer if not. Clean radiator and particles filter, air filters on system covers.

Any Other ErrorContact Alma Technical Support team
System Overheating ProblemIf the system overheats without displaying any fault message
1. Connect another Handpiece to the system, Check if the Handpiece is still overheating. 2. If it's not, then the problem is at the overheated Handpiece, and not on the system. 3. If it does, check the SSR and the voltage supplier for malfunction, and check the output voltage from the SSR that is 24V (DC) with voltmeter connect one prob' to ground and second prob' to the SSR output point,
No Rabbit Processor ConnectedIf the flat cable is not connected properly, an error message will appear when trying to load the software, notifying No Rabbit Processor Connected.
Reconnect the cable and retry to load the software package again.
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: No or low output
- Measure output at the delivery device with a laser power meter against the setting.
- Fit a known-good delivery fibre / handpiece / applicator.
- Confirm the cooling system runs and coolant is at level.
- Check the key, interlock and footswitch are satisfied.
- Escalate a confirmed laser-module or driver fault to the manufacturer; recalibrate power after any module work.
Symptom: Thermal shutdown
- Confirm the cooling fans / pump run and airflow is clear.
- Check the coolant level.
- Let the unit cool and restart.
- Clean the air filters / vents.
- Monitor for recurrence during a treatment.
