... 10 Commissioning and operation
Analyzer cabinet air conditioner
NOTICE
Damage to the air conditioner
Damage to the air conditioner due to incorrect
commissioning.
•
Do not attempt to operate the air conditioner while it is
horizontal or on its side, back or front. The refrigeration
compressor is filled with lubricating oil. This will cause
permanent damage to the air conditioner and also voids
the warranty.
If the air conditioner has been in a horizontal position, be certain
it is placed in an upright, vertical or mounting position for a
minimum of 5 minutes before operating.
Overload protection
The compressor is provided with automatic reset thermal
overload protection. This thermo-switch is located and mounted
inside the plastic enclosure clipped to the compressor.
The switch operates when the compressor overheats due to
clogged or dirty inlet air filter or if ambient air temperatures
exceed nameplate rating or if enclosure dissipated heat loads
exceed the rated capacity of the air conditioner.
The thermal overload switch will actuate and stop compressor
operation. The blowers will continue to operate, and the
compressor will restart after it has cooled to within the thermal
overload cut-in temperature setting.
Principles of operation
If electrical power to the air conditioner is interrupted and
reapplied immediately, (within 3 to 5 seconds), the compressor
may not restart due to the high back pressure of the
compressor. It takes a minimum of one (1) minute after
shutdown for the compressor suction and discharge pressures
to equalize in order for the air conditioner to restart.
Operating the air conditioner below the minimum ambient
temperature or above the maximum ambient temperatures
indicated on the nameplate voids all warranties.
The moisture that the enclosure air can contain is limited. If
moisture flows from the drain tube continuously this can only
mean that ambient air is entering the enclosure. Be aware that
frequent opening of the enclosure's door admits humid air,
which the air conditioner must then dehumidify.
Start-up
Prior to start-up
Check analyzer system seal integrity.
Power supply activation
1. Make sure that all fuse switches are deactivated.
2. Turn on the analyzer system power supply with the main
switch.
3. Activate the fuse switches of the individual modules one
after the other.
Function check
The following events will occur after the power supply is turned
on:
1. The three 'Power', 'Maint' and 'Error' LEDs light up.
2. The different booting phases are displayed on the screen.
Also, the software version is displayed.
3. After a brief time, the screen switches to measurement
mode.
4. The STATUS MESSAGE softkey appears on the screen. This
indicates the possibility of a temperature or flow problem
during the warm-up phase.
•
By pressing the soft key, the user can recall the status
message summary and view status message details.
Date and time check
A correct date and time setting are required for a proper
operation of functions such as automatic calibration and time /
date logging of error messages.
1. Select the date / time menu item:
'MENU / Configure / System / Date / Time'
2. Check and, if necessary, correct the date and time according
to time on board.
3. The analyzer system is factory-set to the GMT+1 time zone.
