Stoelting 51447 Welder User Manual


 
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.
