2.6 Powering Up/Down
2.6.1 General
Before powering up the equipment, confirm that the Modulator has been
correctly installed by checking the following:
1. The Modulator enclosure has been installed in a suitable location.
2. Power supply range has been checked and the relevant fuse has been
set at the rear panel power inlet connector, and a good earth has been
provided.
3. The Modulator has been connected to other equipment and the control
terminal, as required.
2.6.2 Powering Up
With the Modulator correctly installed, power up the unit as follows:
1. Power up the Modulator by turning on the local mains supply. The unit
executes a series of power-up initialisation and self-test routines.
2. Ensure that all cooling fans are rotating. If they are not, switch off the
equipment immediately.
3. Confirm that the front panel green Power LED is illuminated.
4. A warm-up period of 60 seconds (IF Output models) or 5 minutes
(L-Band Output models) is required for the internal 10 MHz reference
to meet specification. The Modulator is available for operation after
performing self-tests.
2.6.3 Powering Down
Power down the Modulator as follows:
1. If required, disable the Modulator output by setting the IF Output state
to Off at the relevant control terminal being used to configure the
Modulator.
2. If required, remove the power supply connection at the rear of the
unit.
