MARSIC200
Decommissioning
1. About this document
The purpose of this document is to allow you to decommission the
product quickly and easily. This document describes the shutdown
procedure and protective measures for long-term storage of the
MARSIC200.
This document is addressed to technicians (persons with technical
understanding) operating and maintaining the measuring system.
The technicians must have been trained on the device.
2. Supplementary and other relevant documents
• Technical Information for MARSIC200 (no. 8017324, English)
• Operating Instructions for MARSIC200 (no.8017322, English)
• Safety Information (no.8019910, English)
You can download these documents from www.sick.com. To find a
publication, enter the relevant part number in the search field.
3. Safety information
b Refer to the device involved for the standards and guidelines of the
Declaration of Conformity used.
b Keep this document, together with the Operating Instructions,
available for reference and pass these on to a new owner.
4. Decommissioning procedure
4.1 Switch to stand-by
1. Set the stand-by switch on the distribution unit to “ON”.
• The maintenance signal on the analyzer switches to “on” and the
yellow LED on the display lights up.
• A zero point validation is performed.
• The sample gas pump and the (optional) bypass pump go off.
• The heaters remain switched on.
• The gas sampling tube and the filter element of the gas sampling
unit is flushed with instrument air.
2. Wait approximately 10 minutes for the sample gas flow to stop:
The flowmeter in the distribution unit no longer shows a flow.
• The heaters remain on and the sampling tube of the sampling
probe continues to be flushed with instrument air.
• You can now leave the measuring system in this state for as long
as required.
4.2 Shutdown
The electric voltage (and thereby the heaters) are switched off in the
following steps.
1. Switch off all fuses in the distribution unit.
2. Turn the main switch on the distribution unit to “OFF”.
• The system is now switched off.
3. Pull out the complete sampling filter unit from exhaust stack.
4. Close flange from exhaust stack with blind-flange.
5. Switch external instrument air off.
6. Close off gas inlets and outlets gas-tight at sampling probe and
analyzer.
4.3 Protective measures for long-term storage
b When gas lines are unscrewed: Close all gas connections (with
sealing plugs, if need be with adhesive tape) to protect internal
gas paths against moisture, dust, or dirt penetrating.
b Cover open electrical connections dust-tight (e. g. with adhesive
tape).
b Protect the control unit against sharp-edged objects. If necessary,
cover the instrument with protective material (e. g.: cardboard, Sty-
rofoam).
b Whenever possible, select a dry, well-ventilated room for storage
(storage conditions: -20 ... +70 °C, dry).
b Pack the device (e.g., in a waterproof plastic sack).
b If high air humidity can be expected: Enclose a drying agent (e. g.
silica gel) in the packaging.
5. Re-commissioning
For commissioning, please see the Technical Information (Installa-
tion and Initial Start-up).

NOTICE:
b This document is only valid in connection with the documen-
tation listed in section 2 of this document. Please read and
observe the safety information and warning notices con-
tained therein.
b Only put the device into operation when this document and
the Operating Instructions have been read and understood.
Contact SICK Customer Service should any questions arise.
NOTICE:
For correct decommissioning, the steps must be carried out
in the following order.
NOTICE:
When switched off prematurely, there is a risk of contamina-
tion by sample gases remaining in the sample gas path.
b Follow the switch-off procedure described below and do not
completely switch the system off immediately.
NOTICE:
b Do not switch instrument air off yet (gas sampling unit is still
flushed with instrument air).
b Take care that the engine/scrubber is not running and that
there is no pressure on the exhaust stack.
NOTICE:
When the instrument air is switched off, there is the risk of
contamination of the sampling tube.
b Do not switch the instrument air off when the sampling tube
is in the exhaust duct.
NOTICE:
The service life of the OXOR-E analyzer module (optional) will
be reduced by contact to oxygen in the air even when the
device is switched off.
