Connect the cable of the operating panel to the connector (b) on
the rear side of the microtome and fasten it with the two screws.
•
Should the operating panel be attached to the instrument, push
the connector through the corresponding hole on the rear side of the
microtome.
•
The operating panel can be used freestanding. It can be placed on
the left as well as on the right side of the microtome.
•
The knobs are separately packed and must be attached to the
operating panel.
•
The knobs can easily be removed and placed on the either side of
the operating panel.
•
Connect the plug of the foot pedal cable into the connector (c) and
fasten the cable on the microtome with the two screws. (optional)
•
Connector (a) is for service purposes only.
Note!
(optional, for users of foot pedal only)
If the foot pedal or interlock connector are not connected, the operating
mode "emergency stop" is used (page 25). In this mode, the electronic hand
wheel brake is activated and the cutting drive motor cannot be started.
Always connect the foot pedal or interlock connector!
Before using the Foot Pedal on HM355S first time (it applies to every
HM355S using the foot pedal first time), you have to consider the
following procedure:
•
Turn on the Microtome.
•
Connect the Dongle (Interlock connector) with connector X16 (c)
on the rear side of the microtome (see figure page 20).
•
Press the button on the Dongle in order to activate the "Emergency
Stop" function.
•
Now disconnect the Dongle. The "STOP" symbol should appear on
the display.
•
Connect the Foot Pedal with connector X16 (c).
•
Vigorously step on the foot pedal as far as it will go.
•
On display should appear the "STOP" Symbol as long as the foot
pedal is being stepped on. It shows that the "Emergency Stop" func-
tion is working properly.
Note!
From now on always use either the Foot Pedal or the Dongle (without Foot
Pedal); the instrument won't work without them.
WARNING:
The functionality of the built in emergency Stop function of the foot pedal has
to be tested every time the foot pedal was newly connected with the microtome.
The test has to be carried out before the microtome is used! After the foot pedal
was connected with the microtome, press down the foot pedal completely.
"STOP" appears in the display, proven that the functionality is granted. The
principle use of the Foot Pedal is written in the user manual of the microtome.
