Read carefully Speed governor instructions before connecting controller Speed governor
interface!
18.1. Electronic engines interface
All below mentioned interface examples describe analog interface even if they are (in some
cases) used
for Electronic Control Units (Electronic engines) with CAN data bus.
There are several possibilities to connect CAN bus interface between Electronic engine and
ComAp controller. Refer to ComAp Electronic Engines Support manual.
18.1.1. Communication Bridge Unit
I-CB unit is an interface between Controller and Electronic engine. Following I-CB types are
available:
For more details see I-CB-ICBEdit-1.1.pdf manual.

18.2. Speed governor interface
18.2.1. Controller Speed reg out voltage limits
Setpoints Sync/Ld ctrl: SpeedGovLowLim [0,01V] and SpeedGovHiLim [0,01V] limit low and
high levels of output voltage. E.g. instead of full –10V to +10V Speed governor output range
can be set SpeedGovLowLim = 0,00 V and SpeedGovHiLim = 5,00 V to reduce the output
range from 0 to 5V.
18.2.2. Interface List
Following chapter describes analog interface to engines with standard electronic speed
governors.
