Setting the actuator
1. Check whether the mechanical unit can be moved freely in the entire travel range. Move
the actuator to the respective end position for this purpose using the
Note
End position
By simultaneously pressing the
2. Now move the actuator to the horizontal position of the lever.
3. A value between "P48.0" and "P52.0" is shown on the display.
4. If a value beyond this value range is shown on the display, you must move the friction
clutch. Move the friction clutch until a value between "P48.0" and "P52.0" is achieved.
The closer this value is to "P50.0", the more accurately the positioner determines the
stroke travel.
Note
Device versions with flameproof enclosure
The inner friction clutch is fixed. Therefore, only move the outer friction clutch. This also
applies when using an internal NCS module.
The following applies to device versions without flameproof enclosure with internal NCS
module 6DR4004-5L.:
The inner friction clutch has no function. This means you should only adjust the
adjustment wheel of the magnet clamp, see section "Internal NCS module 6DR4004-5L/-
5LE (Page 69)". Requirement: The '1.YFCT' Type of actuator (Page 155) parameter is
set.
