22 Electro-pneumatic positioner TZID 42/18-54 EN
The connections have to be arranged, according to their marks, in the following way:
For double-acting actuators, connect the Y2/OUT2 output with the actuator chamber that
provides for the same action as the return spring of single-acting actuators.
A pressure gauge block is available for indicating the supply air pressure and output
pressure. Fasten the pressure gauge block to the side of the TZID positioner. Make sure
that the O-ring seals are positioned properly to ensure tight fitting.
An optional filter regultor can be attached to the pressure gauge block, When attaching
the filter regulator, make sure that the regulator housing is oriented vertically to ensure
that condensed water is drained off. Set the supply air pressure to a maximum value of
16 bar using the ajdustment spindle.
