3 FLUID CONNECTION OF THE POSITIONER
DANGER!
Danger – high pressure in the equipment!
There is a serious risk of injury when reaching into the equipment.
Before loosening the lines and valves, turn off the pressure and vent the lines.•
WARNING!
Danger - improper installation!
Improper installation may result in injuries as well as damage to the device and the area around it.
Fluid and electrical installations may be carried out by authorized technicians only and with the appropriate tools!•
Danger due to unintentional activation of the equipment!
Unintentional activation of the equipment during installation may result in injuries and damage.
Take appropriate measures to prevent the equipment from being unintentionally activated.•
Connection 1
Supply pressure
Connection 3
Exhaust air line or
silencer
Fig. 1: Fluid Installation
Procedure:
Apply the supply pressure to connection "1" (3 – 7 bar; instrument air, free of oil, water and dust) →
Attach the exhaust air line or the silencer to connection “3” →
Keep the adjacent supply pressure always at least 0.5 – 1 bar above the pressure which is required to move the pneu-
matic actuator to its end position. This ensures that the control behavior is not extremely negatively affected in the upper
stroke range on account of too little pressure difference.
During operation keep the fluctuations of the supply pressure as low as possible (max. ±10 %). If fluctuations are greater,
the control parameters measured with the X.TUNE function are not optimum.
