10 Appendix
Other motors are allowable only if the potentiometer connection forms a positive interlock.
10.3 External Switching of the Fuel Motors/ Valves
If there are not enough output channels, it is possible to switch externally between actuators,
which are not needed in every curve set (oil motors and gas motors).
WARNING!
If you use an external switching you must recognise this for safety reasons:
You must ensure that the feedback of the selected motor is also selected, e.g. by using relays
with connected switches.
WARNING!
For switching the feedback signals, you may only use relays with gold contact material.
NOTICE
Recommendation:
Use relay module R30 (type 660R0030) for external switching of the fuel actuators. For infor-
mations about the relay module R30 refer to the data sheet of the relay module (print no.
DLT6105).
