Figure 1-1: CMPT DCL display and alarm module
This Instruction Manual provides detailed wiring connection and configuration
information for the CMPT DCL display and alarm module.
The CMPT DCL is configured by SKF when it is part of an assembled CMPT enclosure.
The CMPT DCL must otherwise be properly installed and configured by the user.
Important: Please read this Instruction Manual and the cautionary notes thoroughly.
·The SKF CMPT DCL is a digital alarm and display module. It is part of a machinery
fault detection system to monitor analog signals from the SKF CMPT CTU vibration
and temperature transmitter, various thermocouples and Resistive Temperature
Detectors (RTDs).
·The DCL is a single channel module with digital display and alarm function with LED
event lamp and relay contacts.
·The front panel digital display provides the user a visual indication of the monitored
signal. The display can be scaled to indicate vibration (gE, g, mm/s, inch/s),
temperature (°C, °F), etc. The DCL has programmable alarm, relay and variable
time delay functions. The DCL can indicate HIGH, LOW, HIGH-LOW, and various
other alarm limits. The front panel event lamp illuminates (red) to indicate alarm.
·The relay contacts are programmable with various options (Normally
Open/Normally Close, Non-latching/latching).
·The DCL provides a 4 to 20 mA output signal proportional to the scaled analog
input signal.

Description
Instruction Manual, Revision D
·Two CMPT DCL modules are needed for stand-alone monitoring of an SKF CMPT
CTU vibration transmitter (one each for vibration and temperature). One CMPT
CTU and two DCL modules together are a user-friendly fault detection system of
machinery vibration and temperature.
·The CMPT CTU transmitter can also be connected directly to a PLC/DCS
automation system without the DCL modules.

Figure 4-3: Front panel
The CMPT DCL has two rows of digital characters:
·the upper row displays the Present Value (PV). The PV is the value received from
the input device (CMPT DCL, either vibration or temperature). The upper row of
digital characters will display the Present Value (PV) from the CMPT DCL
transmitter when in the normal operating (default) state.
·the lower row displays the Setting Value (SV). The SV is an input set by the user
during configuration if the DCL is to use the HIGH-LOW or Range alarm settings.
Otherwise the SV is not used.

Caution
Instruction Manual, Revision D
Caution

Read and understand these instructions thoroughly before working with the CMPT DCL.
The CMPT DCL shall be used by persons qualified to work with electrical
instrumentation.
Caution - Damage or injury can result
•The CMPT DCL is powered by 24 V DC. Do not apply higher voltage.
•Do not connect the sensor input (DC voltage) to the CMPT DCL (terminals 5, 6
and 7) until after the unit is powered and the input type is configured. See sections
"Configuration" and "Configuration for CMPT CTU vibration and temperature
transmitter".
•The CMPT DCL relay contacts are rated 48 VAC/DC, 1 Wmaximum. Do not apply
higher voltage / current.
•Higher voltage (110–240 V AC) power may exist in the same proximity as the
CMPT DCL. Use caution to avoid contact with any voltage source.
•Make sure that the power is disconnected prior to working with electrical wiring.
•Make sure that the CMPT DCL is installed in an environment within its
specifications (see section "Specifications")
Lightning strikes, power surges and other electrical anomalies can damage this device.
For the protection of your equipment, SKF recommends the power connections be
made through a surge protector.
