Connecting the pressure reduction valve
4.1.5.1. Connecting the pressure reduction valve electrically
If the excavator is able to accept proportional inputs or joysticks with the following
output signals, the excavator control system can be linked to the output of the cab
module in order to control the pressure reduction valve via the excavator's ECU:
•
0.5 V to 4.5 V single-channel
•
0.5 V to 4.5 V; 4.5 V to 0.5 V two-channel, crossed signals
•
PWM signal 5 V voltage level
1. Plug the analogue pressure reduction valve cable into the output of the cab
module and connect with the excavator's cable loom, where the original
joysticks were connected.
