UMAX0608XX‐1000. Tri‐Axial J1939 CAN Inclinometer. Version 9B
Page: 60-66
The inclinometer Analog Outputs connector has two identical analog ground pins
AGND
. They
are used as a return path for
AOUT1…AOUT3
. The pins are internally connected together and
with the
Power-
pin on the CAN connector through a low resistance protection circuit, see
Figure 9.
It is recommended to use separate
AGND
pins for current and voltage outputs to improve the
accuracy of the voltage outputs.
Be careful not to use the CAN only output connector mating cable with AX061000 units – the
power on pins 2 and 3 can damage the analog outputs.
6.7.1.2 Unit Orientation
The original default unit frame orientation, together with the
Pitch
and
Roll
angular directions,
is shown on the inclinometer label, see Figure 42. This orientation is suitable for a horizontal
installation.

Figure 42. Horizontal Unit Frame Orientation
The legacy vertical mount inclinometers AX060808 and AX060838 were designed for a vertical
installation when the inclinometer unit frame orientation was not configurable (before firmware
V5.00 was released). Their default unit frame orientation is presented in Figure 43.

Starting from firmware V5.00, the original unit frame orientation can be changed using the
initial unit frame rotation configuration parameters in the
Unit Installation
function block.
It is necessary to remember that the unit frame Z-axis should be coincident with the gravity
acceleration vector when the unit is installed at the customer site.
6.7.2 AX060806
The AX060806 inclinometer has a cast aluminum enclosure with one 4-pin Deutsch DT15-4P
connector, see Figure 44.
