Cable preparation
Remove length from the sensor cable and the shield cable according to the following figure:
l
Assembly
Place the solder sleeve over the sensor cable. The solder preform should be centered over the shield braid.
l
Insert the shield cable to be connected between the solder sleeve and the sensor cable. The shield cable
l
can be laid in the direction of the sensor cable or in the opposite direction (see illustration).
Fix the assembly in a suitable fixture.
l
Heat the solder preform using a heating tool.
l
The solder sleeve shrinks, the inner solder preform with flux melts and solders the shield braid to the shield
cable (a). At the same time, both ends of the solder sleeve are hermetically sealed. The shield connection is
thus reliably insulated and strain-relieved. The quality of the soldered connection can be inspected visually
via the transparent sleeve.
Coaxial cable
Clamping the signal lines
Terminals AI1 to AI16 are provided for vibration signals. The permissible signal type (voltage, IEPE, CLD) results
from the respective system module variant. Terminals AI17 to AI20 are provided for process variables and dis-
placement sensor signals that are fed as voltage or current level. The signal type is configured using dip switches.
Connect the rpm sensors to the tachometer pulse input TP1 or TP2. Feed the trigger signal via terminal TPDC+.
Connect a status signal each to the digital inputs DI1 to DI4. Relay outputs SYS OK and NO1 to NO3 are available for
the connection to the digital inputs of external systems.
Observe the connection specifications in this regard (see
