Commissioning is normally limited to visual inspection in order to ensure correct tubing connections, wiring
and operating voltage supply.
All components, tubing connections and cabling are clearly identified, so that all of the connections can be
readily restored.
11.1
Workstation
To commission the MPS PA station with the sample programs you will need:
•
the mounted and adjusted MPS PA
station
•
a control console with operator unit (e.g., TP700)
•
a PLC EduTrainer with 16 digital inputs and outputs and 4 analog inputs, 2 analog outputs
•
a power supply 24 V DC, 4
A, ≤ 100 W o
utput power, SELV/PELV limited power source (LPS)
•
compressed air supply: 600 kPa (6 bar)
•
a PC with installed PLC programming software
•
two I/O cables (SysLink) and one analog cable

Filling and emptying
1.
Switch off the power supply and pull out the mains plug.
2.
Check the piping and tubing connection of the components for correct seating.
3.
Close the exhaust valve.
4.
Switch off the compressed air supply.
5.
Fill the waste water tank with 6 l of water. The float switch (overflow protection) must not be
mechanically actuated. The float must be horizontal and cover the reed contact.
6.
Check the piping of the components for tightness.
7.
Remove splashing water.
8.
Switch on the power supply at the 24 VDC power supply unit.
9.
Check if the LEDs of the two capacitive proximity sensors indicate a signal after filling.
10.
The tank is emptied when the waste water pump pumps the water into the process water tank via the
filter or the hand valve in the drain line is opened and the liquid flows into a separate tank. To do this,
insert a suitable pipe or piece of tubing into the connection in the drain.
11.
Open the hand valve at the drain to drain the system.
Note
Always empty the station completely if it is not to be used for a long period of time.
