1.5 Limit Switch Tests
NOTE: This test may be combined with 6.7, Software Limit Tests,
on slow-moving antennas where running through both software
travel limits and limit switches independently would be very time-
consuming. To perform the tests in this fashion, first verify that the
Soft limits parameter is Enabled, (refer to paragraph 5.8.6). Use
Manual antenna control from the ACU (refer to paragraph 5.8) to
drive the antenna into its soft limit, then at the drive cabinet,
complete the test by driving the antenna into the travel limit switch.
In this paragraph, the function and setting of the electrical limit switches on the
antenna structure will be checked. Drive the antenna from the drive cabinet, which
allows high speed jogging while also providing viewing access for any possible
obstructions.
Use the following procedures to test the limit switches.
1. a. Drive the antenna using the JOG AZ CW switch until the
limit switch stops the movement of the antenna. _______(Check)
b. Check the 7200 ACU display for a SUM LIMIT message. _______(Check)
c. Record the AZ angle at which the limit occurred. ______ (Record)
d. Verify that the antenna will drive in the CCW direction. _______(Check)
2. a. Drive the antenna using the JOG AZ CCW switch until the
