CAUTION
Unsuitable compressed air
Device damage. As a general rule, the positioner must only be operated with dry and clean
compressed air.
● Use the customary water separators and filters. An additional dryer is required in extreme
cases.
● Use dryers, especially if you operate the positioner at low ambient temperatures.
CAUTION
Note the following before working on the control valve and when attaching the positioner
Danger of injury.
● Prior to working on the control valve, you must move the control valve into a completely
pressureless state. Proceed as follows:
– Depressurize the actuator chambers.
– Switch off the supply air PZ.
– Lock the valve in its position.
● Make sure that the valve has reached the pressureless state.
● If you interrupt the pneumatic auxiliary power to the positioner, the pressureless position
can only be reached after a certain waiting time.
● When mounting, observe the following sequence imperatively to avoid injuries or
mechanical damage to the positioner/mounting kit:
– Mount the positioner mechanically.
– Connect the electrical auxiliary power supply.
– Connect the pneumatic auxiliary power supply.
– Commission the positioner.
WARNING

In order to ensure the degree of protection of the housing (IP66), protect the housing versions
of the positioners listed here from mechanical impact energy:
● 6DR5..3; not greater than 2 Joule
● 6DR5..0; not greater than 1 Joule
● 6DR5..1 with inspection window; not greater than 1 Joule
