1 Calibration Instruction for Salwico ST200

and Salwico ST600EX

1.1 Preliminaries

This instructions applies to the following products:

Figure 1. Salwico ST200. Part No. 4470

Figure 2. Salwico ST600EX. Part No. 4460.

NOTE!

It is recommended to periodically carry out a gas response check on the gas detector

to ensure correct operation.

The ST200 and ST600EX detectors for 0-100% LEL Hydrocarbon can be

calibrated and the out-signal adjusted.

Hint!

Reading at 0% is 4.0 mA, and full range 100% LEL is 20 mA.

Tools

Tools required for this operation are:

•A small terminal screw driver, with thin straight tip.

•A multimeter with mA (milliampere) capacity.

1.2 Prerequisites

1 Use the arrow keys on the control panel to

manoeuvre through the different menus.

Press the right arrow key to access the

menu tree.

2 Scroll to 4 Gas Detectors and press

Continue.

3 Scroll to the detector that should be

calibrated and press Options.

4 Scroll to 3 Disable and choose Continue.

5 You have to confirm the disablement before

you can proceed.

Press Disable to continue.

6 You will get a confirmation message that

the detector has been disabled.

Press Close to continue.

7 If the ambient air is NOT considered

reliable to use to set the ZERO, apply a

clean source of zero gas or compressed air.

8NOTE!

For the following steps in the

zero calibration instruction

proceed to the Salwico ST200 or

ST600EX detector.

9 Connect the Flowcap to the sensor head as

shown in the picture.

Connect the measuring tips of the

multimeter to the test points in the detector.

Plus is red, minus is black.

Hint!

Picture shows a ST200. The

ST600EX has identical

connections and calibration, only

fitted in an EX proof housing.

1.3 Calibrating the sensor (Zero calibration)

Before gas Calibration is made, a Zero-adjustment should be made.

1 Connect the multimeter to the two test

points as shown in the picture.

2 The multimeter readout should be 4.0 mA

with normal air / zero gas exposed to the

sensor.

Adjust to this reading with the ‘Zero’

potentiometer, marked in red. (See where

the screwdriver is placed in the picture.)

1.4 Calibrating the sensor (Span calibration with

test gas)

NOTE!

For the ST600EX the procedure is identical as below, but note that the EX-Seal is

void if the unit is open, so necessary precautions in the working area may be

required.

Check on site what is applicable before the unit is opened up.

1 Connect the suitable test-gas for the

detector, normally a 50% LEL mixture.

Recommendations:

The ST200 and ST600EX can

only respond to gas in normal

Air. This means that

Calibration gas in N2 /

Nitrogen are not suited for

these detectors.

On LNG vessels a 50% LEL

gas of CH4 Methane in air is

to be used.

For LPGs and Tankers we

normally recommend a 50%

LEL C3H8 Propane gas in air.

2 Adjust the reading to 12.0 mA using the

‘SPAN’ pot. See picture.

Figure 3. Detector ST200

Figure 4. Detector ST600EX

3 If the readout of 12.0 mA cannot be

reached even with the “SPAN” pot in the

bottom position, the sensor cell must be

replaced to a new one. Consilium

Replacement article number for ST200 and

ST600EX detectors is 004460-S.

NOTE!

When a new sensor is fitted, a

new Zero adjustment as well as

span calibration should be made.

Catalytic detectors have a

limited lifespan of up to 5

years, but can be ‘poisoned’

by silicones, salt air, very

humid air, etc. and their

output will be reduced.

1.5 Reconnecting disabled detectors

All disablements in the CGD50/500 gas detection system are presented in the

disablements list. Any enablement is made from this list.
