Troubleshooting/Error Codes
Troubleshooting - follow the steps in the order listed for the appropriate problem.
No output power:
1. Check that the generator power switch is in the “on” position.
2. Insure the generator is plugged into a grounded, functioning outlet and that the
power cord is securely attached to the receptacle at the rear of the generator.
3. Check the cables and connections to insure that they are intact and securely
connected.
4. Insure the patient return electrode is properly installed and connected to the
generator. If the patient return electrode alarm light stays illuminated red, see
Patient Return Electrode Alarm Stays On
section.
5. Check that the active accessories are attached.
6. Check to see if the unit is in the “Standby” mode (dashed lines in display) or if the
power setting is too low. Adjust the power accordingly.
7. Turn the generator to the “Off” position and then back to the “On” position.
8. Replace the accessory devices (i.e. pencil, or footswitch).
9. Check the fuse and replace it if necessary.
10. If the problem is not corrected with the above steps, use a backup generator and
return the unit for service.
Diminished Power Output:
1. Check all accessories for proper set-up and installation.
Patient Return Electrode Alarm Stays On:
1. Check the return electrode cables to insure that they are securely attached to the
pad and generator.
2. Make sure “sticky” pads are securely attached to the patient over a good
muscular, vascular area.
3. If the patient return electrode alarm light remains illuminated red, replace the
return electrode and/or return electrode cable.
4. Turn the generator to the “Off” position and then back to the “On” position.
5. If the alarm condition cannot be immediately corrected use a backup generator.
Greater than Expected Neuromuscular Stimulation:
1. Discontinue use of active accessories.
2. Check all connections for secure fit before continuing use of the generator.
3. Decrease the power setting or change to STANDARD COAG from SPRAY
COAG as relevant.
4. If neuromuscular stimulation continues replace the generator with a backup unit.
5. Have qualified service personnel test the generator for abnormal low frequency
current leakage.
6. If excessive low frequency current leakage is detected return for service.
