6.1.4 Actuator without
position feedback
(EMS 5 / 10 / 16)
6.1.4.1 Determine guiding direction
for center positioning
(OMG 4, OMG 8)
If you are using a servo-center transducer OMG 4 or OMG 8 the
guiding direction for operating mode “
center positioning
“ must be
checked.
1. Press key “
Servo-center
“.
The LED of the key lights.
Observe guiding device!
The guiding device must move towards its center position.
If the guiding device moves to one of its stop positions, then
change position of DIL switch
S4.2
on the processor board
(see chapter 5.6.1).
6.1.4.2 Adjust gain of the
servo-center transducer
(OMG 4, OMG 8)
If you are using a servo-center transducer OMG 4 or OMG 8,
preselect the adjustment of gain.
1. Press key “
Servo-center
“.
The LED of the key lights.
2. Press key “
SETUP
“.
The set gain for the servo-center transducer is shown
graphically (bar display) and as numerical value on the lower
edge of the display.
3. Increase gain by means of the arrow key “
right
“, until hunting
occurs (the guiding device starts oscillating).
The display of the gain value rises step by step.
Pressing the arrow key longer than 3 seconds increases the
pulse width until the key is released.
We recommend setting the gain to maximum if hunting does not
occur.
