3.7 Connection to the Open-Drain switching outputs

The four switching outputs are Open-Drain-signals. The output can be connected to external relays

operated with max. 30 V DC with a max. current of 2.5 A. Connecting the alarm relays is optional.

Pin 6 - GND_R is the common ground for all alarm relays.

Picture 7: How to connect an alarm relay

It is mandatory to connect a freewheel diode to the relay (see Picture 7 - D).

3.8 Stand-alone operation

If you want to run the Statox 560 in stand-alone mode (only switching outputs are connected) you have to

short pin number 3 and 4 (see Picture 6) directly in the junction box. This way an ammeter is simulated and

an error code 2 massage is avoided.

5.1 Start - Up, Connecting the Sensor Module

1. Remove the yellow protective cap and unscrew counterclockwise the protection stainless steel

cylinder. Keep the protective cap! It might be useful to protect the sensor head from pollution

when leaving it without sensor module.

2. Take the Sensor Module out of the package. If there is a short circuit bridge (applicable for 2

electrode sensors) remove it. Check for eventual damage!

3. Insert the guiding pins into the relevant drill holes to connect the sensor module by pushing it

carefully upward (see Picture 10).

Picture 10: Connecting the sensor module

4. Now fingertight fasten the protective cylinder. The sealing ring must be clean!

5. The sensor head will now detect the sensor module. The display shows „Loading Parameter“, while

all operation – and calibration parameters are loaded. In case these cannot be read, see chapter

6.2.

6. The Statox 560 will give you the warning „Change of sensor type!“, in case it has been operated

with a different sensor module before. If you really want to change the gas or range, confirm

with . This is intended to prevent the user from connecting a wrong sensor module. If you don’t

want to work with the plugged module you can easily remove the module by pulling it down. Now

you can use the desired sensor module.

7. During the warm-up the display shows alternatingly the menus gas/measuring range/parameter

version and serial number/best before date (week/year). This procedure can take some minutes,

especially with 3-electrode-sensors.

5.3.1 Prooftest

A prooftest checks the sensor head response to gas without triggering an alarm. It can be activated

without entering the password - protected service menu. During the prooftest the sensor head is in the

service mode, i. e. the output signal is on the preset value and the alarms are inhibited.

The display shows the actual concentration.

To perform a prooftest you need calibration adapter art. # 562984, an inert gas tube (e.g. art.# 556710)

and test gas with a concentration within the measuring range, ideally close to the alarm threshold.

1. Check that the O-Ring sits correctly in the calibration adapter. Push the calibration adapter onto the

protection cylinder by slightly turning it. The side marked with “Front” points toward the user.

2. Connect the gas tube at the bottom side to it (compare Picture in Chapter 5.3.3).

3. Enter the menu „Prooftest“ and start the prooftest by pushing . Now open gas valve. Flow: ca.

30 l/h (500 ml/min). The display shows the actual measured value. Depending the age of the sensor

and the gas to be measured, it may take a few minutes until the measured value has stabilized.

4. Switch the gas off and remove the calibration adapter.

5. Wait for the measured value to return to zero before returning to main menu by pushing . Do

not rush – you might otherwise create a false alarm!

Picture 13: Schematics Prooftest

 The timeout during the prooftest is increased to 30min!

 After finishing the prooftest the senor head returns to the recent status. If you start the

prooftest out of the service – menu, the sensor head will remain in the service mode.

5.3.2 Self-test

The Statox 560 performs an automatic self – test with gas every 24 h. The sensor module includes a gas

generator cell, generating a small concentration of the gas to be measured. This give you a reliable

information, if the sensor head is working properly. Please note the following:

1. The self-test schedule is adjustable (see chapter 5.3.2.3). It always starts at the same time except:

a) When temperature is out of specifications, the test is cancelled.

b) If there is gas in the atmosphere, the test is skipped to maintain the measuring function. You will

find the respective limit in chapter 11.

c) If the service or info menu is active, the test will be postponed until service is completed.

d) In case of system failure, the test is canceled.

2. In case the self-test has been skipped three time in a row for reason a) or b), you will get a maintenance

request alarm.

3. During the self-test the Statox 560 is in the service mode.

4. After the self-test the test result is displayed and will be saved. The recent 5 tests can be shown on the

display (see Chapter 0).

5. A non – passed self-test generates a maintenance request alarm.

6. A passed self – test will automatically reset a self-test induced maintenance alarm (self-healing).

7. The self-test can be triggered manually (see chapter 0), either directly at the sensor head or by a

remote self-test button (see chapter 3.6). ). A manually triggered self-test is always additional to the

scheduled test, but its functionality is the same.

8. The remote self-test cannot be triggered if the info meu or the service menu is active or the symbol ✱

is on the display (internal diagnosis is running).

Test procedure:

A small amount of test gas is generated and pumped in front of the sensor. The signal generated by this gas

must reach a minimum level within a maximum time. After purging the sensor with ambient air, the signal

must return to zero within a certain time limit. The sensor head returns to the measuring mode.

More details are included in the sesnsor-specific data in chapter 11.

In this menu you can manually trigger a self –test. Just confirm with to start. Temperature and sensor

signal will be checked.

 If temperature is out of specifications, the test will not start. The display shows „Temp. out of

selftest range“ for 5 seconds and then the sensor head returns into the measuring mode.

 If the sensor signal exceeds a fixed limit, the test will not start. The display shows „Zero out of

selftest range“ for 5 seconds and the sensor head returns into the measuring mode. Gas detection

has always priority before testing. If you are sure, there is no gas present, adjust zero (see chapter

5.3.3).

 During the self-test the sensor head is in the service mode. When it has passed the test the display

shows „Selftest passed“ for 5 seconds and the senor head goes back into the measuring mode. If it

does not pass the relevant error code (see chapter 6.2) is displayed for 5 seconds before the sensor

head goes back into the measuring mode.

5.3.3 Calibration

The menu „Calibration“ can be accessed in the password - protected service menu. Before starting a gas

calibration wait until the sensor head and the sensor module have the same temperature!

You need a Statox 560 calibration adapter art.# 562984, an inert gas tube (i.e. art. # 556710) and span gas

within the specified concentration range (see Chapter 11). If you are not sure, if you are working in clean

atmosphere, use synthetic air for zeroing.

Picture 19: Calibration with gas

Procedure (see Picture 20):

1. Enter the service menu and select „Calibration“. After the last valid calibration is shown.

2. Enter the menu „Calibration Start“ with and confirm with . The timeout is now 30 minutes!

3. The display shows „Zeroing Please wait“ until zero is stable.

4. After zero has stabilized, the display shows „Zero found - Apply span gas“. You may now stop the

calibration procedure, if you only wanted to adjust zero by pushing . If you want to continue

with a gas calibration, confirm with . The display now shows „Apply span gas“.

5. Check that the O-Ring sits correctly in the calibration adapter. Push the gas adapter onto

the protective cylinder by slightly turning it. The side marked with “Front” points toward the user.

Connect the gas tube at the bottom side. Switch the gas on. Flow should be around

30 l/h (500 ml/min).

6. You may connect an active carbon filter to the calibration adapter exhaust, if you want to avoid

span gas getting into the environment. This filter must not create a dynamic pressure. This would

compromise accuracy!

7. As soon as the sensor head detects gas, the display shows „Gas is on“.

8. When the sensor head has found a plateau, the sensor head requires to enter the span gas

concentration in ppm. The display shows the last used concentration, change with the arrow

buttons and confirm with .

9. After saving the concentration the display shows „Calibration done“ and the actual concentration

in the gas adapter. Switch the gas off and remove the calibration adapter.

10. Let the measured value drop to zero before going back with and into the measuring mode,

in order to avoid false alarms.

In case an error occurred during calibration, the relevant error code will be displayed. Potential errors

see Chapter 6.2!

If zero or span adjustment fails, the sensor head continues with the old parameters. The

display will show ZERO ADJUSTMENT FAILED or CALIBRATION FAILED alternatingly with

the measured value until a valid zero or span adjustment has been performed.

5.3.4 Change Sensor – Sensor Module / Sensor / Generator Cell Replacement

5.3.4.1 Sensor module replacement

In menu „Change Sensor“ you can replace the sensor module. In this menu the sensor head is in the

service mode, the timeout deactivated. Thus you will not create an alarm when removing the sensor

module.

Do not remove the sensor module during the measuring mode! You will create an alarm

and probably damage the module!

Caution: EMC - sensitive parts!

 Always be properly grounded when touching the sensor module.  Use a wrist strap connected to a properly grounded work surface and use properly

grounded tools and equipment. Wear conductive clothing and shoes.

 Avoid touching pins, leads and circuitry.

Procedure (see Picture 24):

1. Enter the menu „Change Sensor“ and confirm with . The display shows „Change Sensor -

Replace“. Now the measuring head is in the service mode.

2. Remove the protection cylinder counterclockwise.

3. Pull the sensor module downwards to remove it. The display now

shows „Replace” flashing.

4. Take the new sensor module out of the packaging and remove the

shortening bridge as far as applicable. Check for mechanical damage!

5. Align the guiding pins with the relevant holes and plug the sensor

module in.

6. Fasten the protection cylinder fingertight. Check if the sealing washer

is clean.

7. The sensor head will now read the sensor module parameters, while

the display shows „Loading Parameter“. If these are not legible, you

will get an error message (see chapter 6.2).

Picture 21: Changing the

sensor modules

Page 34

Statox 560

Page 34 of 66 Issue 2/2017

8. If the measuring head has operated with a different sensor type, you get the message „Change of

sensor type!“. If you really want to change, confirm with . This is intended to prevent the user

from connecting a wrong sensor module. If you don’t want to work with the plugged module you

can easily remove the module by pulling it down. Now you can use the desired sensor module.

9. During the warm-up period the display shows alternatingly the gas / measuring range / parameter

version and serial number of the sensor / best before date in the format ww/yy. The warm-up may

take a few minutes.

10. When the warm-up is completed, the measuring head goes into the measuring mode. Allow some

time to stabilize (1 hour), then perform a zero adjustment for maximum accuracy (see chapter

5.3.3).

5.3.4.2 Sensor and Generator Cell replacement:

Instead of replacing the entire sensor module, you can also replace the generator cell or the sensor.

Remove the sensor module cover. Observe the procedures required when handling EMC sensitive

parts. Check the sensor module type plate for the relevant article numbers.

Sensor replacement:

Unplug the old sensor. Extract and remove the short circuit bridge of the new sensor if there is any. Plug

the new sensor, the position of the sensor plug is remote to the module PCB (connect the red wire of the

flat ribbon cable to pin 1). Check for correct positioning! The flat ribbon cable should sink between sensor

and PCB.

Standard Generator Cell Replacement:

Remove the generator cell by pulling it upwards from its seat. Unplug it. Remove both protective caps from

the new generator cell. Plug it in with the cable looking downwards. Push until the stop.

COCl2 Generator Cell Replacement:

Remove the generator cell by pulling its handle upward with a screw driver. Remove the protective cap

form the new generator cell. Take care not to damage the O-Ring. Insert the new cell with the O – Ring

downwards. Turn the cell until the coding latches and push it downwards until the stop.

Close the sensor module. Make sure the top is well – aligned and no wires are jammed. Do not tighten the

screw too hard.

The spare sensor comes with a fresh dust – and splash guard filter. Remove the old filter carefully with a

screw driver, insert the new filter and press it until it latches. You may use the handle of the magnetic pin

as a tool to do that.

6.2 Error messages

The Statox 560 internal diagnosis differentiates between “System failure” (SF) and “Maintenance

Request” (MR).

A system failure is a fatal dysfunction. The system is unable to operate. Except power outage these errors

are shown on the display.

A maintenance request may be caused by operating errors or short – term problems during self-test or

calibration. These error messages mostly are displayed only for a short time. An error history can be read in

menu “Errors Info“. A maintenance request which has been caused by a non - successful self-test will

automatically be deleted by a successful self-test (self-healing).

7 Maintenance and Cleaning

7.1 Routine treatment

 Perform visual inspection on a regular schedule. In particular check the washer between flange and

protection cylinder for its condition.

 Check regularly for pollution, especially the area of the gas entry.

 Clean the Statox 560 with a humid cloth. Do not use any detergent, solvent, or water jet.

 If the Statox 560 is operated as a SIS requiring functional safety, a regular prooftest is mandatory.

 Check the real time clock in regular time intervals and adjust clock time when necessary (see chapter

5.3.11).

7.2 Replacing the pump

For the exchange of the pump you have to remove the sensor module. Open the Change Sensor menu and

then do steps 1 to 3 (see chapter 5.3.4.1).

Procedure (see Picture 32):

 Release the pump plug by pushing down the safety bar and pulling the plug at the same time.

 Loosen the pump screw by one turn counterclockwise and pull out the pump.

 When connecting the new pump, the free pump nozzle must be plugged into the narrow opening and

the retaining plate must be lead under the pump screw. Shift the pump to the stop and tighten the screw.

 Connect the pump plug.

 Mount the sensor module. See menu item Change Sensor, chapter 5.3.4.1, from point 5.

Leave the filter at the pump input! It protects against pollution and regulates the pump

flow.

9 Functional Safety

This Chapter provides all information required to operate the Statox 560 as a Safety Instrumented System

(SIS) rated SIL 2.

The intended use of the Statox 560 is in the responsibility of the customer.

9.1 Safety Functions

Safety Function 1 (SF1)

The Statox 560 including gas sensor detects a toxic gas. The concentration is monitored at the analog

output as current in the range 0 - 22 mA. Two open collector outputs monitor the system status

maintenance request (MR) and system failure (SF). The system status is also monitored at the analog

output with:

 0 mA = System failure

 2 mA = service mode

 4 mA = 0% of the measuring range

 20 mA = 100% of the measuring range

 22 mA = over range

Safety Function 2 (SF2)

The Statox 560 including gas sensor detects a toxic gas. It monitors exceedings of the programmed alarm

thresholds at the open collector outputs A1 and A2. The two open collector outputs maintenance request

(MR) and system failure (SF) are for maintenance request and system failure warnings.

9.2 Diagnostic Time and Measuring Cycle

The maximum internal fault detection time is 24 hours. Within this period hardware and sensor failures will

be detected, and the sensor head will go into safe mode if necessary.

The measuring cycle is 1 second. The output current, the display and the open collector outputs are updated

in the same time interval.

9.3 Installation and Parameter Settings

The following procedures are mandatory to be performed in order to achieve a valid data

base with regards to failure rates and SFF!

 The automatic self-test must be activated (see chapter 5.3.2).

 The system failure and the maintenance request output (see chapter 3.7) must be connected to an

external alarm device each (e.g. horn, flashlight, flashing LED).

 The signal current during the service mode must be set to 2 mA (see chapter 5.3.12), in order to have

a clear differentiation from the measuring mode.

 The outputs A1 and A2 must be set to „passive“ (see chapter 5.3.10), in order to detect a potential

cable rupture (only requested for safety function 2).

 Ambient conditions must be within specifications (see chapter 10).

9.4 Schedule Maintenance

The following maintenance work must be done on a regular schedule in order to maintain accurate gas

detection:

 Observe the prooftest intervals. Additionally to the prooftest (see chapter 5.3.1), perform a

functional test (see chapter 5.3.13) in the same interval.

 When the sensor best before has been exceeded, either replace the sensor or perform a prooftest

or a gas calibration.

 In harsh environment, where a poisoning, pollution or other damage of the sensor is likely, shorten

the prooftest interval.

 If you receive corresponding error messages (see chapter 6.2), replace the sensor or perform a gas

calibration.

 Observe the cleaning and maintenance recommendations in chapter 7.

9.5 Repair and Spare Parts

The Ex d housing and the electronics do not include any customer serviceable parts. Use only original spare

parts and consumables.
