Connection for electric throttle lever control with 4–20 mA output signal b) Voltage supply to the throttle lever control system via battery terminal 30/31 If the throttle lever systems are connected to the battery voltage the safety measures provided by the manufacturer must be taken into account. If the current consumption of the deck shiftgear during operation is constantly max. 3 A, terminals 30 (Bat+) and 31 (Bat–) in the terminal box can be used for this (see picture). However, this assumes that apart from the EDC control unit, the BE1 system and the instruments no other consumers are supplied via the terminal box (16 A fuse). Otherwise the system is connected direct to the battery.
Illustration – excerpt from 51.17098–8688: Heavy-gauge conduit thread ubion Connection for voltage supply for throttle lever: max. 3 A Kl. 31 Kl. 30 Terminal box Ensure that the throttle lever control system is disconnected from the battery if the boat is left unattended for a fairly long period (several days). To do this use the battery main switch. Otherwise the battery may discharge and in unfavourable cases there may be difficulties in starting. Mini-Marex-C system: current consumption at 24 V supply voltage 97 Closed-circuit current consumption with two command initiators (main bridge and flybridge) approx.
0,6 A Nominal current consumption with two command initiators Actuator with electric gearbox output approx. 3 A
