Chapter 5 - General Operation
5.5.1 Main Rotor Track
Do main rotor track operations, as follows:
1. Install a single interrupter on the rotating swashplate, in the same way
as the user would for any track-and-balance operation.
NOTE: If the aircraft installation normally uses a double
interrupter with the other single interrupters, remove the double
interrupter and other single interrupters so there is only one single
interrupter on the rotating swashplate.
2. Mount the magnetic pickup, in the same way as the user would
normally.
3. Connect the magnetic pickup cable to the channel A connector of the
Vibrex unit.
4. Connect the tracking cable to the serial port on the connector
subpanel.
5. Connect the Strobex to the five-pin connector of the tracking cable.
6. Connect the two-pin receptacle to and appropriate dc power source.
The following dc power is necessary for each of the different Strobex
models:
NOTE: The Strobex does not operate on a 12V battery but does
work on an active (charging) 12-Vdc buss. The voltage required to
operate the Strobex is approximately 13.5V.
Strobex Model Power Required
135M-10, -10A, -10B, -10C and -12 12 or 24 Vdc
135M-11 24 Vdc only
