2.1
2.1.1
For your safety
Basic safety information
▸
Read and observe these Operating Instructions.
▸
Observe all safety information.
Correct use
▸
Only use the measuring device as described in “Intended use”. The manufacturer assumes no responsibility for any other use.
▸
Maintenance work should be performed as prescribed in this Manual.
▸
Do not perform any work or repairs on the measuring device not described in this
Manual.
▸
Do not remove, add or modify any components to or on the device unless described and specified in the official manufacturer information.
▸
Use only original spare parts and wear and tear parts from SICK.
Failure to observe these precautions could result in:
●
●
Voiding the manufacturer's warranty.
Causing the device to become dangerous.
Special local conditions
In addition to the information in these Operating Instructions, follow all local laws, technical rules and company-internal operating and installation directives applicable wherever the device is installed.
Retention of documents
These Operating Instructions:
▸
Must be available for reference.
▸
Must be conveyed to new owners.
Ensure the operational safety during all work on the device
The VISIC100SF is mainly used in combination with regulation and control technology.
▸
During all work on the device, ensure that this can not lead to hazards or hindrances for traffic.
Electrical safety
Hazard through electrical shock
●
●
There is a risk of electric shock when working on the measuring device with the voltage supply switched on.
● Before starting work on the measuring device, ensure the power supply can be switched off using a power isolating switch or circuit breaker in accordance with the valid standard.
Switch off the power supply before carrying out any work on the measuring device.
After completion of the work or for test purposes or adjustment, the power supply may only be activated again by authorized personnel complying with the safety regulations.

2.3
Dangerous substances
Hazard through acidic liquids
If the gas sensor is mechanically damaged, corrosive liquid may escape and cause serious injury.
●
●
Take appropriate protective measures for work (e.g., by wearing a safety mask, protective gloves and acid resistant clothes).
In case of contact with the skin or eyes, rinse the affected parts immediately with clear water and consult a doctor.
Hazard through escaping calibration gases
●
●
●
Incorrect handling of calibration gases can cause high concentrations above the workplace exposure limits to escape from the gas sensor into the ambient air and lead to poisoning.
Observe the Safety Datasheets of the calibration gases.
Ensure adequate ventilation.
Limit gassing time.
Intended use
The Gas Adjustment Kit serves to check and adjust the gas sensors in the VISIC100SF.
Requirements for personnel qualification
The device may only be operated by authorized persons who, based on their training on, and knowledge of the specific device, as well as knowledge of the relevant regulations can assess the tasks given and recognize the hazards involved.

The term measuring point (MP) refers to a gas sensor connected to the VISIC100SF.
For a sensor with digital communication, the display shows
DP = Digital Measuring Point.
The number following is always 1 because the adjustment tool can only address one sensor.

Power-on time
Power-on time
Gas sensors require a warm-up time until the measurement process reaches a stable state. During this warm-up time, the sensor signal can lead to the unwanted triggering of a pseudo alarm. Therefore, the power-on time is started after switching on the voltage or voltage recovery. During this time, the sensor outputs “Warm-up time” instead of the measured value.
The factory-set power-on time is 5 min. and can only be read out.

ADJUSTMENT 7
Adjustment
An electrochemical process always leads to a loss of sensitivity over time. Therefore, an adjustment of the zero point and the sensitivity is necessary at regular intervals.
Safety
WARNING: Hazard by voltage.
Live parts are accessible when the device is open!
▸
Only use suitable, insulated tools.
WARNING: Hazard by corrosive liquids
If the gas sensor is mechanically damaged, corrosive liquid may escape and cause serious injury.
▸
Take appropriate protective measures for work (e.g., by wearing a safety mask, protective gloves and acid resistant clothes).
▸
In case of contact with the skin or eyes, rinse the affected parts immediately with clear water and consult a doctor.
▸
Dispose of damaged gas sensors immediately.
WARNING: Health hazard due to defective gas cylinders
The use of defective test gas cylinders for adjusting the electrochemical cells can lead to accidents and health hazards.
▸
Do not use expired test gas cylinders.
▸
When handling pressure vessels, observe the required safety regulations.
WARNING: Hazard through escaping calibration gases
Incorrect handling of calibration gases can cause high concentrations above the occupational exposure limits to escape from the gas sensor into the ambient air and lead to poisoning.
▸
Observe the Safety Datasheets of the calibration gases.
▸
Ensure adequate ventilation.
▸
Limit gassing time.

Preparation
NOTICE:
Risk of destruction of electronic components by electrostatic discharge (ESD)
When touching electronic assemblies, there is a risk of the assembly being destroyed by electrical equipotential bonding.
▸
Make sure you have the same electric potential as the subassembly (e.g. by grounding) before touching the subassembly.
NOTICE:
Entering a too high test gas concentration on the adjustment tool can lead to incorrect adjustment of the electrochemical cell.
▸
Ensure the correct test gas concentration is used depending on the gas concentration,
NOTICE:
The warm-up phase for the gas sensors takes 5 minutes.
▸
Do not interrupt the connection to the gas sensors or the voltage supply of the
VISIC100SF when opening it.
The 5-minute warm-up phase of the gas sensors will otherwise restart.

1 Zero point adjustment
2 Sensitivity adjustment
The sequence cannot be changed.
Duration: 3 ... 10 minutes.
The gas sensor terminates the adjustment mode automatically after a certain period of inactivity (typically 10 minutes).
Connections between gas sensor and test gas cylinder
To obtain reliable results during adjustment, make sure the hoses and sampling valves are used correctly. All parts are marked accordingly:
For CO and synthetic air (parts are marked in pink):
– Hose, transparent
– Hose adapter
– Transition piece for tapping valve
– Brass tapping valve, flow rate: 0.5 l/min
For NO and NO
2
(parts are marked blue/orange):
– Hose
– Hose adapter
– Transition piece for tapping valve
– Stainless steel tapping valve, marked blue, flow rate: 0.5 l/min
NOTICE:
Only use undamaged sealing rings on the tapping valves.

Performing zero point adjustment
Procedure
1 Screw the hose adapter for synthetic air (marked pink) into the thread under the sensor to be calibrated.
2 Attach the hose for synthetic air (marked pink) to the hose adapter.
3 Screw the closed sampling valve (marked pink) onto the test gas cylinder with synthetic air.
4 Connect the corresponding transition piece (marked pink) to the tapping valve.
5 Connect the open end of the hose to the transition piece.
6 On the calibration tool: Menu: “Confirm”

7 Press “Confirm”.
>>> Current actual value is displayed.
8 Open the sampling valve for feeding the test gas.
Note:
The flow rate is set to a fixed value of 0.5 l/min for all gases.
9 Press “Confirm” to start the adjustment procedure.
>>> New zero offset is calculated.
>>> During the calculation, an underscore runs from left to right in the 2nd line.
>>> The actual value drops to “0”.
10 When the actual value is stable, press “Confirm” and finish calculation of the value.
>>> “Save“ appears.
>>> After successful saving, a square is briefly displayed on the right.
>>> Zero point adjustment is finished. New zero point offset is saved.
>>> Display automatically changes to the display of the current actual value (new zero point).
11 Press “ESC”.
12 Close the gas sampling valve to stop the gas sampling.
13 Pull the hose off the hose adapter.
