1.2 Short description
The low pressure controller (hereafter called
“Regulator”) reduces the pressure in the
supply line of an application system by
means of the control air to the required mate-
rial pressure. It protects the downstream
devices from pressure surges and pulsa-
tions.

4.2 Assembly
Fig. 2: Assembly drawing (example)
Personnel:
nMechanic
n + additional qualification explosion pro-
tection
Protective equipment:
nProtective workwear
nEye protection
nProtective gloves
nSafety boots
Observe the following at assembly:
nEnsure a non-explosive atmosphere.
nInstall the regulator before the applicator.
nAlignment: Lid on top, regulator housing
at bottom
nFlow direction
nProvide shut off valves (1).
nEnsure pressure monitoring. Install pres-
sure gage if necessary.
nIf necessary, install filter before the regu-
lator.
nProvide pressure switch (3) if necessary.
The pressure switch is integrated in the
control. In the event of leakage, the pres-
sure switch issues a pressure message to
the control system. In the event of
leakage, the control system switches the
system off.
nObserve maximum tightening torque for
all screw connections.
nVibrations in the pipelines can cause
screw connections to come off loose.
1. Fit regulator (6) into the pipeline.
2. Screw cap nut of material supply line (7)
to the material inlet.
3. Tighten cap nut of material outflow pipe
(2) to material outlet.
4. Connect transparent hose (4) to leakage
connection.
5. Connect control air (5) Ä 11.5 “Operating
values”.

5 Commissioning
5.1 Safety Instructions
WARNING!
Danger from harmful or irritant sub
stances
Serious injuries or death can result if you
come into contact with dangerous fluids or
steam.
nRegulator Check regularly for leakage.
Observe local regulations and mainte-
nance schedule.
nEnsure that the forced ventilation is
operational.
nFollow the safety data sheet.
nWear specified protective clothing.
nAvoid contact (e.g. with eyes, skin).
WARNING!
Squirting material
Escaping compressed material can cause
serious injury.
nCheck the product for leakage before
commissioning.
nPut the product into operation only if
the connections are made professio-
nally.
WARNING!
Sparks due to electrostatic discharge
If the regulator is not grounded, there can
be an electrostatic charge on the the regu-
lator. Electrostatic discharge can cause
sparks that in explosive atmosphere can
cause a fire or an explosion. Serious injury
and death could be the consequence.
nGround Regulator as specified.
nBefore carrying out any work, make
sure that there is no explosive atmos-
phere.
NOTICE!
Material damage due to dry run
If the regulator is operated without mate-
rial, it wears out faster.
nAlways operate a regulator with mate-
rial.
