SKF CMSS-ONL-2504 Quick Start Manual

CMSS-ONL-2504
Acoustic Emission (AE) Interface Cable Assembly for the
SKF Multilog On-line System IMx

Connections

• Blue wire: AE sensor signal / phantom power line
• Green wire: AE sensor 0 V return
• Red wire: ICP signal
• Black Wire: ICP ground
• Screen: Cable shield

Simple installation

• To install the CMSS-ONL-2504:
– Mate the connector with CMSS 786M sensor, using thread lock
(Loctite 243 recommended)
– Connect the blue wire to J1-1 (input +) of CMON 2504
– Connect the green wire to J1-2 (input –) of CMON 2504
– Connect the red wire to IMx channel terminal A [ + ]
– Connect the black wire to IMx channel terminal B [ – ]
– Connect the cable shield to IMx chassis ground bar
• Mount the CMSS 786M sensor per installation instructions
• Connect the CMON 2504 per installation instructions
Terminal A or B refers to IMx-S
Terminal + or – refers to IMx-W
The cable screen is connected to the body of the sensor and is
usually grounded by the sensor. Note that where the sensor is glued
into position, there may not be an electrical connection and the cable
screen may need to be connected to the earth strip below the DIN
rail.

Configuration

In order to configure IMx-S, IMx-T or IMx-M and SKF @ptitude
Analyst / SKF @ptitude Observer, it is necessary to position DIP
switches in the used channels as shown in figs. 1 and 2. Only change
DIP settings when the IMx unit is powered off.
