Range adjustment

See nameplate for signal range, supply pressure
and stroke.

8.1.1

Connect air supply to the "SUPPLY" port of the
actuator and an adjustable signal source to the

"SIGNAL" connection. Attach a dial gauge to the
actuator (see Fig 14).

8.1.2

Undo the zero adjustment locknut until it is a few
threads free of the actuator housing. Set the
signal to the low end value (e.g. 0,2 bar or 4 mA).
Adjust the dial gauge to zero.

8.1.3

Set the signal to the high end value (e.g. 1,0 bar or
20 mA).
