6. Operating the VibroCheck

6.2Using the VibroCheck with the VT1200S

The following instructions must be adhered to exactly. Noncompliance can cause serious damage to the instrument.

We recommend using the VibroCheck after each blade change for check- ing the optimum position of the blade and important sectioning parameters.

Prior to assembly, the dovetail guide (3) is brought down to the lowest position using the DOWN key!

1. The user installs the VibroCheck: the VC is pushed along the dovetail guide (3) past the mark on the base plate of the instrument (rear stop) and clamped firmly using the lever (15). Insert the blade and clamp tightly. Return the blade to the cutting position (see Fig. 19).

2. Plug the connecting plug of the VibroCheck (VC) into the corresponding socket on the left side panel. The LED on the VC quickly flashes red --> then it remains red. The control panel detects the VC (see Fig. 30). The LED in the DOWN key flashes green.

3.The user presses the DOWN key. The VC moves to the bottom position, in addition to that the blade moves to the rearmost position – the

LED in the RUN/STOP key flashes. Short red flash of LED on VC --> it then remains red.

4. The user presses the RUN/STOP key: the blade first moves towards the front (into the posi- tion exactly above the VibroCheck); the VC then moves into a position in which the blade partly covers the light barrier. LED on VC flash- es green – RUN/STOP flashes yellow. The con- trol panel displays: "VIBRO search" (see Fig. 30). A search can last up to 1 minute. When LED on VC is green and LED in RUN/STOP is yellow, the blade starts to vibrate.
