8 Multi-role Recorders User Guide (HW/BK/0034 | 12 Oct. 2021)

Multi-role recorder grounds

The multi-role recorder has the following three grounds:

•

GND: internal electrical ground

•

CHASSIS: mechanical ground

•

POWER(-): 28V return

OTE

All three grounds are isolated from one another inside the multi-role recorder.

GND

GND is the zero volt line that all internal signal conditioning modules use. All input and output signals on the multi-

role recorder are referenced to this potential. The GND point is also available on the multi-role recorder Power

Supply Unit (PSU) connectors.

CHASSIS

Each multi-role recorder has a mechanical ground available using the ground mounting bolt (see

Figure 1 on

page 4

). Mechanical grounding is also available using the CHASSIS pin on the multi-role recorder I/O connector

(where available). This pin is connected to the multi-role recorder chassis.

POWER(-)

POWER(-) is the return line for the 28V multi-role recorder power supply.

OTE

The POWER(-) pin is not connected to the CHASSIS line or GND line within the multi-role recorder.

Grounding a multi-role recorder

Each ground must be connected to the main star point on the aircraft or vehicle using a low impedance connection.

Hence the GND pins on a multi-role recorder PSU connector, the CHASSIS pin on the PSU connector (if available)

and the POWER (-) pin on the PSU connector must be connected directly to the star point. It is acceptable to use

the ground mounting bolt on the PSU instead of the CHASSIS pin. A common cable must not be used to take more

than one of these signals to the star point.

OTE

To prevent interference between different grounding connections, when more than one multi-role recorder

is used, each multi-role recorder must be connected to the star point using individual cables. Shared cables

must not be used. See examples of grounding configurations in the following two figures.
