12 PERFORMANCE CHECKS
Before every application, the user should check the functional efficiency of the unit and the
accessories. The ICC is equipped for this with various automatic performance checks that, each
time the power switch is switched on, proceed briefly and thus signal and display recognized
errors. However, not all possible errors are automatically detected and displayed.
12.1 Automatic performance test after switching on the unit
Each time after switching on, the unit goes through an automatic performance check. If
performance errors are detected here, these errors are signaled acoustically and an error number
assigned to the respective error is displayed. The following performance errors of the unit and of
accessories connected to the unit can be automatically recognized:
1. If a key on the front panel is depressed or shorted out due to an error once the power switch
is switched on, this error is signaled acoustically after switching on the power switch and
displayed by an error number.
2. If a key on the electrode handle is shorted out or bypassed at low resistance (e.g. due to
moisture in the electrode handle) due to an error or depressed while the power switch is
switched on, this error is signaled acoustically after the power switch is switched on and
displayed by an error number.
3. If the contact of a footswitch is shorted out due to an error or if a pedal is stuck or a pedal
is pushed while the power switch is switched on, this error is signaled acoustically and
displayed by an error number.
12.2 Automatic performance check during activation
After every activation, the unit goes through an automatic performance check. If performance
errors are determined here, these errors are acoustically signaled and an error number assigned
to the respective error is displayed. The following performance errors of the unit and before
accessories connected to the unit are automatically recognized:
12.2.1 Check of the HF output voltage
If the HF output voltage deviates from the set HF output voltage when activating a certain
operating mode, e.g. CUTTING or SOFT COAGULATION, the unit produces visual and acoustic
warning signals.
12.2.2 Automatic check of the neutral electrode
If during activation, the connection to the neutral electrode is interrupted, or if the contact resistance
(only for a divided neutral electrode) is too high, the unit switches the HF generator off, produces
an acoustic warning signal and displays the error by an error number.
