Stoelting 51447 Motor Connector, Connection to Earth, Trigger Input, Special Adjustments, Fuses

Motor Connector

The motor cable from the micromanipulator has to be inserted to this 7-pin jack on the backside of the case.

Connection to Earth

On the left side of the backside of the case there is an uninsulated 4mm jack. It can be connected to earth, if necessary.

Trigger Input

There are two BNC-jacks on the rear panel triggering the X-forward/backward movement by positive external TTL- pulses (rear panel: left/right: forward/backward). Every pulse follows a step movement of the manipulator. A continuous movement results, if the frequency of the pulses exceeds 20 Hz. Settings see 'Basic Operation'.

Before opening the cover

disconnect mains.

Special Adjustments

This unit operates on 115 V ac or 230 V ac. The voltage selector is inside the case. To change the range first unplug the power cord and than open the case (4 screws under the rubber pads on the bottom). Now switch the voltage selector near the transformer with a screwdriver. In no case adjust the 6 trimmers inside the case.

Note: The fuse must be changed, if the line voltage is changed (see below: 'Fuses')

Fuses

This unit is protected by a slow blow fuse of 50 mA (line voltage 230 V) or by a slow blow fuse of 100 mA (line voltage 115 V), which is easily accessible from the backside of the case. Under the transformer is a thermal fuse (98 °C). This should only be replaced by the manufacturer.

Piezo Translator

The piezo translator is adjusted very carefully to move only axially. It must be handled with extreme care: Incautious use of force could impair the adjustment or even destroy the drive. Lateral vibrations are mainly caused by the repulsion of the piezo translator and depend on the mass distribution of the used basic manipulator. In order to eliminate these vibrations a second piezo translator has to be mounted in opposite direction to the back of the first translator and has to be electrically connected to this. A second piezo translator has to be ordered separately.

Holder for Micro Capillaries

For the best operation use only the specially constructed micro- capillary holders. Holders with too much or unevenly distributed mass cause vibrations and impair operation.
