Operation
71
After successful login, automatic initialization and query of the components starts. The
current values are displayed in the status window:
Measuring gas flow: Appears after activation of the suction pump (100 ± 10 l/h).
Suction pump in the basic device: The pump switches on 50 K before reaching the
target temperature.
Furnace temperature: Dependent on the target temperature set the heating-up du-
ration is approx. 30 – 60 min.
NDIR detector (C, S or C/S determination only): The C/S module requires a run-in
time of approx. 15 min. after activation.
Coulometer (Cl determination only): approx. 10 min run-in time
In the status window, the displays for the components that are not yet ready for opera-
tion are red during this time.

Preparing the multi EA 4000 and C/S module
WARNING
Risk of electric short circuit! In the combustion furnace HTS1500 very high electrical
currents occur in spite of a low voltage (max. 14 V). The combustion tube is part of the
cover of live components.
Only switch on the analyzer with the combustion tube inserted! Always switch off the
analyzer from the mains switch at the rear of the device for conversions and mainte-
nance to the combustion tube or combustion furnace.
CAUTION
There is a risk of burns at the hot the combustion furnace! Allow the basic device to
cool down sufficiently before conversion!
The gas sluice for C/S measurements consists of a base element and a pressure ring. In
the gas sluice a circular gap remains between the base element and the pressure ring
to allow oxygen to enter the combustion tube. The base element is also used for meas-
urements using the automatic TIC solids module.
