Configuration
Instruction Manual, Revision D
Configuration
7
The CMPT DCL is configured by SKF when supplied assembled as part of an SKF CMPT
enclosure. See Section “Default configuration when DCL is part of an SKF enclosure” for
the default settings.
The DCL must be configured by the user if supplied as a separate component (i.e. part
of a CMPT 1CM type kit).
The DCL is configured by pressing the keys on the front panel. There are four “setting
modes”to set the configuration.
The four Setting Modes have the following functions:
·Main Setting Mode (Press the Key (Key 9) to enter this mode) – Sets the
desired value for the Setting Value (SV). The setting value is used as part of the
alarm level setting if a High-Low or Range type monitoring is desired.
·Sub-Setting Mode (Press the Key while holding the Key) –Sets the Alarm
setting and other optional features.
·Auxiliary Function Setting Mode 1 (Press the Key while holding the Key) –
Locks the settings of the DCL.
·Auxiliary Function Setting Mode 2 (Press the Key while holding the Key
beneath the SKF logo) – Sets the input type voltage), digital display scaling, alarm
mode, relay features, and alarm delay, and converter function.
The following figure is a schematic diagram of the four setting modes.
Figure 6-5: CTU configuration diagram
Note: The basic configuration of the DCL is made in Auxiliary Function Setting Mode
2.
The user must enter one or more of the ‘Setting Modes’ to change the default settings
of the DCL or to set the initial configuration of the DCL. Upon completing the
configuration of each setting mode the DCL returns to the PV display. The configuration
is saved even when disconnected from the power source. The settings can be locked to
prevent unintentional changes in Auxiliary Function Setting Mode 1.

Instruction Manual, Revision D
Once entered into a Setting Mode, the user sequences through the settings using the
Mode Key (Key 9). The , Keys (Keys 7 and 8) are used to set a parameter or
value. The settings for the CMPT DCL to monitor the CMPT CTU are defined in the
section “Configuration for CMPT CTU vibration and temperature transmitter”on the
next page.
Important: Changing the configuration in Auxiliary Function Setting Mode 2 will
change the alarm level setting made in Sub-setting mode. The alarm level setting
should only be made after the configuration in Auxiliary Function Setting Mode 2.
The CMPT DCL is a multi-functional device. It can monitor various types of analog
signals (voltage, current, thermocouple, RTDs) and display and alarm in different ways.
See the Appendix for tables for each Setting Mode, meaning of each Key step, and
listing of the sensor input types.

2. Scaling high limit setting vibration
Vibration
The DCL can be configured to indicate the actual vibration level (gE, g, mm/s or
inch/s) based on the Range setting of the CMPT CTU or the percentage of full CTU
scale (100 %).
If the DCL is set for the percentage of full scale, the CMPT CTU Range can be
changed without the need to re-configure the DCL. The default setting (0 to
100 % full scale) is recommended when the value of the vibration is low (i.e. Range 0
or 2). Use the tables below to set the DCL to indicate actual vibration
value.
For percentage of full scale, set the Scaling high limit setting = 9999*.
