General Safety Information

Requirements for

Safe Operation

In order to operate in a safe and efficient manner the unit should be properly

handled and stored, correctly installed and started, properly operated and

carefully maintained.

comparable equipment and certified as being capable of such work should work

on the unit.

Important Notes and

Regulations

It is important to comply with:

•The content of this operator’s manual

•The safety information affixed to the unit

•The applicable safety precautions for installing and operating electrical devices

•Safety precautions for working with gases, acids, condensates, etc.

National Regulations The regulations, standards and guidelines cited in this operator’s manual are

Safety Tips for Handling Electronic Measurement Devices

Protective Lead

Connection

The protective lead should be attached to the protective lead connector before

any other connection is made.

Risks of Loss of

Protective Lead

Continuity

The unit can be hazardous if the protective lead is interrupted inside or outside the

unit or if the protective lead is disconnected.

Proper Operating

Voltage

The unit voltage must be set to match the line voltage before the power supply is

activated.

Risks Involved in

Opening the Covers

Current-bearing components can be exposed when the covers or parts are

removed, even if this can be done without tools. Current can be present at some

connection points.

Risks Involved in

Working with an

Open Unit

The unit must be disconnected from all power sources before any maintenance

work is performed. Work on a unit that is open and connected to power should

only be performed by trained personnel who are familiar with the risks involved.

Charged Capacitors The unit capacitors can retain their charge even when the unit is disconnected

from all power sources.

Use of Proper Fuses Only fuses of the specified type and rated current should be used as replacements.

Never use patched fuses. Do not short-circuit the fuse holder contacts.

When Safe Operation

can no Longer be

Assured

If it is apparent that safe operation is no longer possible, the unit should be taken

out of operation and secured against unauthorized use.

The possibility of safe operation is excluded:

•If the unit is visibly damaged

•If the unit is no longer operational

•After prolonged storage under adverse conditions

•After severe transport stresses.

Chapter 1 Preparing the Installation

Normal Operation

Normal Operation The SCC-E sample gas feed unit is designed for continuous dosed sample gas

feeding.

The SCC-E sample gas feed unit with Peltier cooler is additionally designed for

cooling the sample gas and separating and removing the condensate.

The SCC-E sample gas feed unit must not be used

•for feeding mixtures of gas/air or gas/ oxygen that are capable of ignition during

normal service,

•for feeding flammable gas, which can combine with air or oxygen to form an

ignition-capable mixture, or

•in a potentially explosive atmosphere or in hazardous areas.

Requirements for the Installation Site

Short Gas Feed Paths The sample gas feed unit should be installed as close as possible to the gas

analyzer.

Adequate

Air Circulation

Ensure adequate natural air circulation around the sample gas feed unit. Avoid

heat accumulation.

Protection against

Adverse

Environmental

Conditions

The sample gas feed unit should be protected from

•Cold,

•Radiated heat, e.g. from the sun, kilns or boilers,

•Temperature fluctuations,

•Strong air movement,

•Dust deposits and dust penetration,

•Corrosive atmosphere,

•Vibration.

Climatic Conditions Ambient temperature In operation: +10 to +45 °C

During Storage and transport: –25 to +60 °C

Relative humidity ≤75 % year-round average, ≤95 % on 30 days per

year, occasional light condensation permissible

Power Supply

Power Supply Input voltage 230 VAC, 50 Hz or 115 V AC, 60 Hz

Power consumption 230 V AC, 50 Hz: 1.05 A, 240 VA

Sample Gas Inlet Conditions

Sample Gas Inlet

Conditions

Sample gas pressure pabs = 70 to 105 kPa (0.7 to 1.05 bar)

Sample gas flow 7 to 70 l/h

Sample gas inlet temperature +10 to +50 °C

Sample gas inlet dew point Version without cooler: The dew point of the sample

gas must be at least 5 °C lower than the lowest

ambient temperature anywhere in the sample gas

feed path. If this is not the case, then a sample gas

cooler unit or a condensate trap is required.

Version with Peltier cooler: max. 50 °C

Chapter 2 Sample Gas Feed Unit Installation

•If there is shipping damage which points to improper handling, file a damage

claim with the shipper (railway, mail or freight carrier) within seven days.

•Make sure that none of the enclosed accessories are lost during unpacking (see

section “Scope of Delivery”, page 7).

•Keep the shipping box and packaging material for future shipping needs.

Installing the Sample Gas Feed Unit

Step Action

Mount the sample gas feed unit on the wall using 4 M6 screws (not

supplied). The mounting brackets required for this purpose are

mounted on the rear of the side panels in the factory.

To enable the cooling air to pass unobstructed out of the

sample gas feed unit to the rear, the projection of the mounting

brackets of around 2.5 cm to the rear wall, which is set up in

the factory, must not be reduced.

2 If necessary, remove the condensate outlet hose from the peristaltic

pump and pull it out backwards.

Install the

Sample Gas Feed Unit

on the Wall

3 If necessary, remove the handle and close the threaded holes.

Step Action

1 Unscrew the mounting brackets from the rear of the side panels and

screw them securely at the front of the side panels, flush with the front

panel, using the threaded holes provided for this purpose.

Exchange the fittings flange on the case cover with the blank flange

on the rear wall.

Take care not to bend or squash any hoses.

3 If necessary, remove the handle and close the threaded holes.

4 If necessary, remove the adhesive pads from the bottom.

Install the

Sample Gas Feed Unit

in a 19-inch

Cabinet/Rack

5 Mount the feed unit in a 19-inch cabinet/rack using 4 M5 screws.

Step Action

1 Unscrew the mounting brackets from the rear of the side panels.

If necessary, exchange the fittings flange on the case cover with the

blank flange on the rear wall.

Desktop Installation
