Instruction Manual
Parallel Wiring with Secondary CTU
To monitor a machine with two of the three possible analysis types – Acceleration
Enveloping, Acceleration or Velocity – one accelerometer sensor and two CMPT CTU
modules are wired parallel to one another. A secondary CTU module is wired parallel to
a primary CTU. The RANGE switch of the secondary CTU is set to the appropriate
buffered signal input ON selection. See the wiring diagram below. The CTU(s) analog
output signals can be connected to a PLC/DCS or CMPT DCL module for monitoring.

The SENSOR OK lamp will be red if the temperature sensor is not connected. A 100
W
or a 120
W
resistor is required between CTU terminals 2 and 3 to avoid the red
SENSOR OK lamp.

Table 7-4: Connections
Set the secondary CTU to the desired RANGE having a buffered input signal ON (RANGE
8 to F). A 100 to 120
W
resister is required between the secondary CTU terminals 2 and
3 since a temperature input is not used.
