12 Ultrasound Controller Manual
Connecting the Air Sensor
Maximum cable length depends on the Air Sensor, see Air Sensor manual. The Air Sensor cable
can be ordered in different length and should not be extended. The unshielded part of the cable
should be no longer than 40mm.
SAC, PAC, DAP, APS and DAT uses M8 connectors. Screened cable with 4pin M8 connector can
also be used. Then instead of green, black is connected and instead of yellow, blue.
If D72 is mounted inside a metal cabinet it is good to connect D72 to the cabinet (ground) and this
is best done using shielded cable glands for the Air Sensor cables. If shielded cable glands are
not used then terminal 11 or 16 on the D72, DP72 or terminal 14 or 19 on D128 can be connected
to the cabinet instead. Note that Air Sensor PAC needs a short jumper cable. To minimize the risk
of electric interference and noise, see Electric Noise page 10.
Connecting the Air Sensor Ex via Ex-barrier
In hazardous area, intrinsically safe barriers must be used to connect SAC Ex, CCS Ex or FCS Ex
to the Ultrasound Controller. In this table connection is shown for a dual channel zener ex-barrier
