WinLink 1000 Installation and Operation Manual Chapter 2 Installation and Setup
To maintain Overvoltage (Installation) Category II, install a suitable
surge suppressor device in the branch circuit to limit expected
transients to Overvoltage Category II values.
The limits are based on IEC60664 and are also located in Table 2H of
UL60950 (for mains 150V, the transient rating is 1500V;
for 150V < mains 300V, the transient rating is 2500V;
for 300V < mains 600V, the transient rating is 4000V).
Warning
2.10 Aligning ODUs with the Beeper
Perform the WinLink 1000 ODU alignment using the beepers located
inside the ODUs. The beeper facility is not suitable for aligning the All
Indoor Units (AIND). To align an AIND system see
Appendix D
.
To speed up the installation time, alignment of a WinLink 1000 Link
can be performed by two teams simultaneously, at site A and at site B.
Æ
To align the ODUs via ODU Beeper:
1. Verify that power is connected to the IDUs at both sites.
Warning
Do not stand in front of a live ODU.
2. The ODU starts beeping 20 seconds after power up, and continues
beeping until the ODUs are aligned, and the installation is
complete.
3. Verify normal operation of the IDU by the LED indications on the
front panel. (See
Normal Indications
.)
4. Coarsely align the site B ODU in the direction of the site A ODU.
5. Make an azimuth sweep of 180 degrees with the site A ODU. So
that the strongest signal from site B can be learnt.
