3. INSTALLATION AND OPERATION
Excel unit
Trident-type
After deciding from the table which alignment telescope to use for the Excel units being aligned
the telescope assembly must be fitted to each of the units in turn starting with the Transmitter.
There are two ways of attaching the telescope to the Excel units - using latches or using a
bayonet fitting. Depending on the type supplied refer to the relevant procedure described
subsequently.
The bayonet style telescope is used on both the Transmitter and Receiver of the short range
Excel. The bayonet-style telescope is also used on the Receiver of the medium and long range
Excels. The latch-style telescope is used on the medium and long range Excel Transmitters.
latch-style telescope assembly
This telescope assembly consists of a telescope and mirror assembly attached to a datum
mount that features a latching mechanism. It can be used with either the Trident or non-Trident
types of Excel units.
When used with the non-Trident Excel the alignment may also need to be fine-tuned and then
verified using the SHC1 Handheld Interrogator.
The latches are used to lock the whole assembly onto the body of the Excel unit.
Before securing the latches the telescope can be rotated to a convenient viewing position.
To remove the telescope assembly reverse the following fitting procedure.
(a)
Fit the datum mount of the alignment telescope securely over the cowl of the
unit as shown so that the face of the mirror is visible.
Ensure the datum mount is fully home on the cowling.
(b)
Undo the latches on the alignment telescope's mounting latch assembly and
rotate the assembly so that the parallel support bar fits underneath the unit
as indicated by arrow 2.
