2 - 6 QuickCollect CMDT 391 / CMDT 391-Ex
User Manual – Revision B
External Sensor Setup (not compatible with the CMDT 390 sensor)
The CMDT 9 has ee egieered to support a to-wire, constant current powered,
external accelerometer that provides an output of 100 mV/g and a bias voltage to
indicate sensor OK.
For the connection to the CMDT 391, the correct SKF cable (part no. CMAC 8010) must
be used, Figure 2 – 7 below. This ale has a -pi oetor that ates ith the uits
external sensor/charging connector,
Figure 3 - 1.
Figure 2 - 7.
CMAC 8010 – External sensor cable for the CMDT 391.
Important: Note that the CMDT 391-Ex uses cable part number CMAC 8010-Ex.
Refer to the safety instructions for specific conditions of use and the
entity/connector parameters to be considered when selecting a suitable Ex
approved external accelerometer.
The SKF recommended external accelerometer for use with the CMDT 391 is the
CMSS 2100 and for the CMDT 391-Ex it is the CMSS 786A-IS.
Ensure the external sensor cable is securely attached by following these steps:
• Loate the sall oth o the QuikCollet oetor.
• Align the cable connector's keyway to that notch and press gently to join the
two connectors.
• Tighten the screw lock on the cable mounted connector to secure it (do not
over tighten).
Or alternatively:
• Press the two connectors gently together and slowly rotate one connector until
the keyway slides into the notch, and then tighten the screw lock to secure.
The maximum total external ale legth the CMDT 9 a drie, is etres. The
CMAC 8010 cable is 2-metres long so the maximum length of additional external cable is
8-etres.
The other end of the external sensor cable has a 2-pin (MIL-C-5015) connector suitable
for direct connection to standard SKF accelerometers. If the cable is to be attached to
another type of connector then a suitable adapter must be sourced.
