4.2 Checks before commissioningCheck tightness of the total plant before start-up

4.2.1 Checking the gas solution lines and the diapgragm non-return of the injector• Observe the manual of the injector!

4.2.2 Checking the tightness of the vacuum linesVacuum lines are all lines between vacuum regulator and injector.• Close all container valves• Close the rate valve• Open the shut-off valve at the injection unit• Open motive water valve• Switch on the booster pump• Open the rate valve

Floater shows gas flow or vacuummeter shows more than - 9 m w.c. => Leakage in vacuum line!• Close rate valve• Switch off booster pump• Close motive water valve• Close the shut-off valve at the injection unit• Check the vacuum lines and the connection. If necessary, • carefully re-tighten them.• Check tightness again!

– Floater shows no gas flow, vacuummeter shows -9 m w.c. or less => Vacuum lines are tight.

WarningEnsure that all container valves are closed before connecting!Only use the intended gas lines!

WarningCheck the tightness not until the total plant is ready for start-up.Danger of gas leakage! (chlorine breakout)

Note

More possible reasons for insufficient operating vacuum• injector layed out too weakly or defective• injector obstructed• booster pump layed out too weakly or defective

to injector from vacuum regulator

12 / 36

4.2.3 Checking the tightness of pressure gas linesPressure gas lines are all lines from the gas containers to the vacuum regulator.• If the plant is equipped with a nitrogen rinsing device: Check tightness roughly with nitrogen.• Detailed checking with amonia.

Checking the tightness with nitrogen• Close all container valves• Open container connection valves and all shut-off valves up to the gas dosing system• Open the connection valve of the nitrogen cylinder• Slowly open the valve of the nitrogen cylinder, until the lines have a pressure of about 10 bar (read at the

manometer of the vacuum regulator).

• Apply soap water to all components under pressure– Formation of bubbles and/or pressure drop at manometer: Leakage in pressure lines!

Depressurize the plant!Eliminate leakage!Check tightness again!

• No formation of bubbles, pressure at manometer does not drop significantly within one hour: Pressure lines are tight.

Checking the tightness with ammonia• Open all container valves and container connection valves and quickly close them again• Slowly pass the open ammonia bottle along pressure-gas leading parts• Formation of white mist: Leakage in pressure lines!

Depressurize the plant!Eliminate leakage!Check tightness again!

Fig. 11 Formation of white mist

– No formation of white mist: Pressure lines are tight.

Despite constant operating conditions the dosing flow varies

Diaphragm in differential pressure regulator is soiled Clean the diaphragm

Diaphragm in differential pressure regulator is damaged Replace the diaphragm

Leakage at the rate valve Bar gasket in the rate valve damaged Replace the bar gasketFloater of the measuring tube is not caught Measuring tube is soiled Clean the measuring tube

Desired dosing flow is not reached

Insufficient injector vacuum Check injector, observe the manual of the injector

Servomotor (option) does not reach the 100 % -position

Adjust the potentiometer of the servomotor resp. check the settings of the electronics

Leakage in vacuum line between differential pressure regulator and injector

Eliminate leakage (see "checking the tightness")

Vacuum line between differential pressure regulator and injector too long

Observe table "suggested line lengths and diameters"

Vacuum line between vacuum regulator and gas dosing system too long

Observe table "suggested line lengths and diameters"

Admission pressure at the vacuum regulator too low

If necessary, open gas supply or clean filter (observe manual of the vacuum regulator)

Regulating channel of the adjusting plunger soiled Clean the adjusting plungerDespite correctly displayed gas flow the desired gas solution concentration cannot be reached

Leakage in vacuum line between vacuum regulator and gas dosing system

Eliminate leakage (see "checking the tightness")

Servomotor does not run Servomotor is switched to manual operation Switch servomotor to automatic operationServomotor does not reach the whole range desired Servomotor resp. electronics adjusted wrongly Adjust servomotor resp. check settings of the

electronicsServomotor runs in wrong direction Servomotor resp. electronics adjusted wrongly Adjust servomotor resp. check settings of the

electronics

The adjusting spindle (see figures in chapter 5.4) falls from the ’’automatic’’ position into the ’’manual’’position unintentionally

The spring-loaded thrust pad has been displaced and therefore cannot deliver enough preload to the holding groove of the adjusting spindle.

Adjust the thrust pad.

The spring-loaded thrust pad is damaged.

Exchange the spring-loaded thrust pad (96690346 or 50.1340); gently press on the ball. The adjusting spindle must be able to move up and down.

• Set the nut (see fig. 27-29, item 3.14) with the special tool to the distance measured before• Remount the differential pressure regulator• Establish the connections

5.6 Adjusting the Servomotor (option)

In case of repairs or exchange, it may be possible to readjust the servomotor.

Caution Do not remove the suspension wire of the spring!


Caution Observe fitting position of diaphragm and diaphragm disk!

WarningCheck the tightness before restarting (see chapter 4.2 ff)Danger of gas breakout!

Note The servomotor is already adjusted by works if ordered together with the system.

WarningThe servomotor may only be adjusted by qualified personnel, as the mains power has to be switched on.Danger!Do not touch bare wires or clamp screws!

5.6.1 Servomotor without Electronics

Fig. 15 Adjust limit switch

• Take off the cover of the servomotor.• With the connected controller, move the servomotor to 0% dosing flow (as indicated at the measuring tube).

The gear rack at the rate valve must jut out for at least 1 mm.

• Adjust this position as zero point of the controller. Adjust lower limit switch (ST1, see figure 16) to this position of the servomotor.

• Set the controller to 10 %. • Check the dosing flow indicated at the measuring tube. If it is not 10 %:

Adjust the zero point again. Possibly the floater reaches the end stop at a dosing flow of more than 0 %.• With the connected controller, move the servomotor to 100 % dosing flow (as indicated at the measuring tube). The

gear rack at the rate valve must jut out for maximum 31 mm.

• Adjust upper limit switch (ST2, see figure 16) to this position of the servomotor.• Remount the cover of the servomotor.

5.6.2 Servomotor with built-in Electronics

Fig. 17 Potentiometer and dosing flow

• Take off the cover of the servomotor.• Connect the current source 4-20 mA to terminals 8 and 10 and set it to 4 mA. If no current source is present:

disconnect terminal 8.• With the potentiometer Ymin, move the servomotor to 0 % dosing flow (as indicated at the measuring tube).

The gear rack at the rate valve must jut out for at least 1 mm.

• Adjust lower limit switch (ST1) to a value just below Ymin.• Set the current source to 5.6 mA (this corresponds to 10 %). This and the following step cannot be done without a

current source.• Check the dosing flow indicated at the measuring tube. If it is not 10 %:

Adjust the zero point again. Possibly the floater reaches the end stop at a dosing flow of more than 0 %.• Set the current source to 20 mA. If no current source is present: connect terminal 8 to terminal 6.• With the potentiometer Ymax, move the servomotor to 100 % dosing flow (as indicated at the measuring tube).

The gear rack at the rate valve must jut out for maximum 31 mm.

5.6.3 Manual operation of the servomotorIf necessary, the servomotor can also be operated manually.

• Take off the cover of the servomotor.• Set the switch to ’manual’.• Put the servomotor manually into the desired position with an insulated wire jumper, which is temporarily plugged

into the terminals 16/17 or 17/18.– By bridging of the contacts 16 and 17, the servomotor move to the position ’close’.– By bridging of the contacts 17 and 18, the servomotor move to the position ’open’.

• Remount the cover of the servomotor.(Automatic operation is set by setting the switch to ’automatic’.)

Fig. 19 Manual operation of the servomotor

5.6.4 Remote indication of the slide switch position• Remote indication of the manual/automatic slide switch position is possible if required. The tap is made with the

terminals 13,14 and 15.

In the figures 24 to 32 the spare part sets are marked with an asterisk. We suggest to store some spare part sets to ensure fast replacing of wearing parts (only by authorized personnel), if necessary.
