Operating Instructions-No. 803 150
Work on the valve should only be carried out by specialist staff and with the correct
tools!
Before working on the system, always turn off the supply voltage!
Clean the piping system before installing the valve!
Where necessary, connect a strainer upstream to protect against faults.
When tightening the connections, never use the coil as a lever!
Ensure that the operational conditions agree with the performance data of the unit!
Avoid back-pressures in the exhaust channels by the use of large-volume silencers!
ATTENTION!
4 INSTALLATION, INITIALISATION AND SERVICE
4.1 Setting up block assemblies using the modular
pneumatic rail MP07
With combination of two-way and three-way base modules, you can assemble valve blocks
of any size.
It is advisable to start the assembly with the left-hand connector
module. (Fig. 1).
NOTE
ATTENTION!
Squashed O-rings and profile gaskets sause leackages in
the block!
Check that each module is completely pre-fitted with O-rings!
Before locking together, lightly grease or oil the fitted O-rings.
Insert the hooks of the module being added into the slot on the previous module,
ensuring that the O-rings are correctly seated!
Press the modules together until both hooks latch.
Ensure that the profile gaskets are correctly seated on the base module!
Lines or valves must never be loosened while the system is
under pressure!
Observe the pressure indicator on the right-hand connecting
module.
• Pressure indicator with indicating pin on the connecting module - right - (Fig. 1)
- Indicating pin can be pressed in: pressure in valve block < 1 bar
- Indicating pin cannot be pressed in: there is pressure in the valve block
- Indicating pin springs back: there is pressure in the valve block
(vent the system before dismantling
lines or devices)
