Mounting The Brewer - Kipp & Zonen BREWER MK IV Instruction Manual

5. Check the Safety Switch as follows, taking care not to break the nylon cord:
Rotate the Tracker slowly until the black blocking mechanism mounted to the large circular
disk is positioned within the Sensor, which is mounted beneath the Safety Switch, This is the
"reference" position of the Tracker.
Ensure that the Tracker will rotate a full 420° in a CCW direction, and 90° in a CW direction
from this reference position without activating the Safety Switch or breaking the nylon string.
Leave the Tracker such that the blocker is a few degrees CCW from the sensor.
6. Connect the AC Power Cable to the 120V / 230V connector on the underside of the Tracker (
the green Power Indicator will remain off) - if it comes on, push the Power Switch to turn the
power indicator lamp off.
7. Rotate the Tracker a few degrees and note that it is relatively easy to turn when power is off.
8. Press the Tracker Power Switch to turn power ON, and observe that the green Power
Indicator Illuminates.
Attempt to rotate the Tracker again, and note that it is much more difficult to turn with holding
9.
torque on the motor.
10. Activate the Safety Switch manually by pushing the toggle to the right (BE CAREFUL, AS
THERE IS 120V OR 230V INSIDE THE TRACKER HOUSING), and note that the Power
Indicator remains illuminated, but now the Tracker turns easily again.
11. Deactivate the Safety Switch, and turn the Tracker Power Switch OFF.

MOUNTING THE BREWER

Refer to Figure 3.3.
1. Place the Brewer on top of the Tracker. The Brewer Power Switch should be directly above
the Tracker Power Switch, and the three bolts protruding from the top of the Tracker mate to
the three tapered holes in the bottom of the Brewer - these three bolts form a kinematic
mount for the Brewer Optical Assembly.
Secure the Brewer to the four Tracker mounting fixings with the bolts provided in the Basic
2.
Spares Kit - there are spare bolts taped to the inside wall of the Tracker.
When securing the Brewer to the Tracker, start the bolts by hand to ensure that no cross-
3.
threading occurs before using the Allen Wrench included in the Basic Spares Kit to do the
final tightening. Care must be taken not to overtighten the bolts as the rubber feet may be
damaged.
4. Connect the AC Power Cable to the 120V/230V connector on the underside of the Tracker,
and connect the Data Communications Cable to the Surge Suppressor Box assembly
mounted to the underside of the Tracker.
5. Connect the remaining cables from the Tracker to appropriate connectors on the Brewer –
Note that each cable / connector combination is unique, which makes it difficult, but not
impossible, to mate the cables incorrectly.
Turn ON the Tracker Power Switch and the Brewer Power Switch - both Green Power
6.
indicators will come on, the Brewer will go through an initialization sequence once again, and
the Tracker will be difficult to turn by hand.
Turn the Brewer and the Tracker Power Switches OFF, and remove the communications

cable from the Tracker.
