Do not attempt to carry a fully assembled unit alone, preferably, lift
the measurement unit from the shield. The two main parts, the
measurement unit (12 kg) and the shield (18.5 kg), can be lifted and
carried separately.
Startup
This section describes the different aspects of Ceilometer CL31 that
need to be considered before starting up the device.
Startup Procedure
Open the unit door with the key included in the delivery. Make a
visual check of the internal connectors and subassemblies (refer to
Figure 11 on page 32 for further information if necessary). Then
proceed as follows:
1.
Turn the main circuit breaker F1 to the
Off
position (for
location, see Figure 12 on page 33).
2.
Plug in the line supply cable to connector J2 (for location, see
Figure 7 on page 25) after checking the voltage of the power
supply cable connector.
3.
Turn the Main Circuit Breaker F1, the Window Blower Circuit
Breaker F2, and the Battery Switch to the
On
position. After the
initialization routines, the
Laser on
LED starts blinking at
2-second intervals. Also the six diagnostic LEDs light up. For
location of the LEDs and switches, refer to Figure 12 on page 33
and Figure 13 on page 34.
NOTE
For switching the CL31 power fully off, also turn off the battery
switch in addition to the line power switch. Having the unit on with
the battery supply will drain the battery.
WARNING
Make sure that nobody is viewing the unit from the beam direction
with magnifying optics.
