Adjust the range of the analog signal to match the switch positions (min. and max.
position):
1. Set cam I to the required high-fire position (e.g. 85°; position is indicated on the scale
next to the cam).
2. Set cam V to the required low-fire position (e.g. 20°).
3. Preset the signal at the analog input according to the required high-fire position
(e.g. 20 mA).
4. Turn the potentiometer for maximum angular rotation
a) clockwise, if the actuator has not yet reached its maximum angular rotation, or
b) counterclockwise until the actuator starts
5. Preset the signal at the analog input according to the low-fire position (e.g. 4 mA).
6. Turn the potentiometer for minimum angular rotation
a) counterclockwise, if the actuator has not yet reached its minimum angular
rotation, or
b) clockwise until the actuator starts
Modulation always takes place between high- and low-fire.
Also, it is possible to define a closed position or a separate ignition position by setting
cam VI (independent of cam V, e.g. for defining a position higher than the low-fire
position).
