Sensor Interconnect Panel
The sensor interconnect panel (Figure 4.10) provides connections to the primary sensors and controllers
on the dynamometer.
Figure 4.10 Sensor Interconnect Panel
Load Cell 1
Plug the load cell (strain gauge) cable into panel connector marked Load Cell 1.
Tach
Plug the tach sensor cable into the connector labeled Tach. The other end plugs into the absorber speed
sensor.
Fuel 1 & Fuel 2
Fuel flow measurement turbines or meters are connected to the sensor box sensor interconnect panel.
Connect the cable to Fuel 1 and the cable to Fuel 2. Be certain to plug it into the correct turbine to ensure
the calibration matches the turbine. Calibration values for each flow turbine are entered in the configuration
file.
Aux 1 & Aux 2
The Auxiliary #1 and Auxiliary #2 inputs are direct (not multiplexed) analog voltage inputs. These inputs are
designed for a 0–10 VDC signal and configured for the sensor type in the software. A common application
for these inputs is Air/Fuel or lambda sensors. Insert the auxiliary input cable into the connection labeled
Aux 1 & 2 on the sensor interconnect panel. This cable splits into multiple connections. Connect other
extension cables required for the sensor type used to the other ends of the auxiliary input cable.
NOTE:
If your system is utilizing the AEM wideband option, you will not need to use this cable.
This connector is also used to input digital signals for WinDyn off/on indicators from external switches.
A cable is available that has the connections for Auxiliary #1 and Auxiliary #2 plus two digital input
connections (DI-1 and DI-2).
