DEUTZ CMPS Power Supply and CAN Bus Module 1247 0960KZ

Overview of the DEUTZ CMPS Power Supply and CAN Bus Module

The DEUTZ CMPS is a compact plug-in electronic module carrying part number 1247 0960KZ (also written 1247-0960KZ). Its front label identifies it as part of the DEUTZ TEM Evolution range and describes its job in four words: Power Supply + CAN bus. In other words, the module sits inside a TEM Evolution control installation and provides the supply and CAN communication connection point that the neighbouring electronics rely on. This page documents only what is printed on the module itself and what can be read from it, because a complete public datasheet for this part has not been located.

Seven Star LLC supplies the DEUTZ CMPS to maintenance teams, panel builders and engine service departments in Oman and the wider GCC. The unit shown on this page is a real module photographed with its original label, so you can compare the markings character by character with the part you are replacing before you place an order. Seven Star LLC can confirm the part number against the module label and help with compatibility enquiries before a purchase order is raised.

What the Label of the DEUTZ CMPS Tells You

A well-printed label is the most reliable source of information for this module. Reading it from top to bottom gives the following facts. The DEUTZ logo identifies the manufacturer. The words TEM Evolution are printed diagonally across the face, which is how the product family is named. The short code CMPS is the module designation, the line Power Supply + CAN bus states the function, and 1247 0960KZ is the part number to quote when ordering or searching for documentation.

Two rows of terminal markings appear on the label, one at each end of the housing, and two small indicator windows labelled 24V and 5V sit in the middle of the face. Nothing else is printed on the front, which means this module is deliberately simple: it has no display, no buttons and no configuration switches that are visible from the outside. That simplicity is useful in service work, because the number of things that can be set wrongly is very small.

Function of the DEUTZ CMPS in a TEM Evolution System

TEM Evolution is the electronic control and monitoring system documented by DEUTZ Power Systems for its TBG and TCG gas engine series (developed by AVAT Automation), and its I/O modules are connected over CAN. The DEUTZ CMPS combines two supporting tasks in one housing: it takes a 24 V supply on its upper terminals, and it brings the CAN bus lines, the CAN ground and the cable shield out on its lower terminals. The label shows both functions explicitly, and the two LEDs, one for 24V and one for 5V, indicate that the module works with a 24 V input and also has a 5 V rail that is visible to the technician.

In practice this makes the module a convenient place to look first when a TEM Evolution cabinet shows a communication fault or a loss of power to the bus electronics. With the DEUTZ CMPS, a technician can see at a glance whether the supply is present and whether the internal 5 V rail is alive, before opening any wiring or connecting a laptop. The exact internal design of the DEUTZ CMPS is not published in the sources we could verify, so we do not describe internal circuitry, isolation or protection features here.

Terminal Layout Printed on the DEUTZ CMPS

The upper plug-in terminal block carries four markings, which are 24V, 0V, TRM1 and TRM2. The 24V and 0V positions are outlined in red on the label, the usual way of highlighting supply connections. TRM1 and TRM2 are marked in plain black; the label does not explain them, and we do not guess their purpose. In CAN installations, terminal pairs of this kind are often related to bus termination, but the correct use should always be taken from the TEM Evolution wiring documentation for your engine and panel rather than from assumption.

The lower plug-in terminal block carries C_H, C_L, C_GD and SHLD. These abbreviations follow the common CAN naming for the high signal line, the low signal line, the CAN ground reference and the cable shield. The marking appears twice on the label strip, which is a feature of the printed label on this module. Both terminal blocks are plug-in connectors, so the field wiring can be unplugged and re-fitted as a set without removing the module from its mounting.

Key Features Visible on the DEUTZ CMPS

The following points are taken directly from the module and its label, and none of them depends on unpublished specifications.

• The module carries the DEUTZ brand and the TEM Evolution family name on its front face, so its origin and system family are clear at a glance.
• The label states the function in plain words, Power Supply + CAN bus, which removes any doubt about what the housing is meant to do.
• Part number 1247 0960KZ is printed in full, which allows exact matching against engine parts lists and service records.
• Four labelled terminals at the top provide the 24V and 0V supply connections together with the TRM1 and TRM2 positions.
• Four labelled terminals at the bottom provide the C_H, C_L, C_GD and SHLD connections for the CAN bus.
• Two indicator LEDs, marked 24V and 5V, give a quick visual check of the supply condition without test equipment.
• Plug-in terminal blocks on both ends of the DEUTZ CMPS make removal and replacement faster than with hard-wired designs.
• A slim housing allows several modules to be mounted side by side in a control cabinet, as the supplied photograph of two identical units shows.

Installation and Replacement Guidance

When replacing a DEUTZ CMPS, begin by recording the full label text, including the part number suffix KZ, and photograph the existing wiring before anything is disconnected. Isolate the 24 V supply, release the upper and lower plugs one at a time, and note which wire sits in which position, using the printed terminal names as your map. Fit the replacement DEUTZ CMPS, restore the plugs in the same positions, and re-apply the supply. The 24V and 5V LEDs should then illuminate; if they do not, stop and review the supply wiring before suspecting the module.

Take particular care with the DEUTZ CMPS CAN shield and ground connections, because intermittent communication faults on CAN networks are very often caused by poor shield or ground termination rather than by failed modules. Keep the bus cable routed away from power cables, and follow the wiring diagram supplied by DEUTZ for your engine and panel for cable type, termination and maximum bus length. We do not state figures for these here because they depend on the installation and on documents we cannot publish.

Technical Information for the DEUTZ CMPS

The table below lists only information that is printed on the module label. Electrical ratings such as supply range, current consumption, ambient temperature range and enclosure protection are not listed, because we have not found an official published source for them. If your project needs those values, request the original DEUTZ documentation for your system or contact us and we will help you establish them for your application.

Datasheet and Documentation Status for the DEUTZ CMPS

Buyers searching for a DEUTZ CMPS datasheet will find that we could not locate a standalone public datasheet for this module. Product information for TEM Evolution hardware is normally contained in system manuals, wiring diagrams and service documents that are issued to engine owners and service organisations, and we did not find an official copy of the CMPS description on a public DEUTZ document server. For that reason no PDF is attached to this page, and we deliberately avoid attaching third-party copies of unclear origin. When we obtain an official DEUTZ document that covers the module, it will be added here.

Applications of the DEUTZ CMPS in Oman and the GCC

The DEUTZ CMPS is relevant wherever TEM Evolution electronics control TBG or TCG gas engines, for example gas gensets used for power generation and combined heat and power in industrial and utility sites around Muscat, Sohar, Salalah and Duqm. In these environments, a failed supply or communication module can leave an engine unavailable, so maintenance planners often prefer to hold a spare module on the shelf. Seven Star LLC can help you identify the correct DEUTZ CMPS from the label and the engine serial number. Ask us whether a spare is right for your cabinet.

For panel builders who need a 24 V source for auxiliary equipment alongside a TEM Evolution cabinet, a general-purpose unit such as the SELTA Conv 24 may be of interest, although it is not a substitute for the DEUTZ CMPS and must not be used in its place.

Call To Action

To request a formal quotation for the DEUTZ CMPS part number 1247 0960KZ, send the label photograph or the engine serial number to the Seven Star LLC instrumentation team in Muscat through the RFQ form on this page. We will confirm availability, lead time and delivery to Oman and the GCC, and we will tell you plainly, so that every order is placed with accurate expectations, which technical details we can confirm and which require the original DEUTZ documentation.

TEM Evolution System Context of the DEUTZ CMPS

The label of this module names the DEUTZ TEM Evolution family. According to the DEUTZ Power Systems system manual for the TEM Evolution System, the system is documented for the gas engine series TBG 616, TBG 620, TCG 2016, TCG 2020 and TCG 2032. The manual describes a PLC-based system with an operating terminal, in which events such as faults, alarms and parameter changes are written to an operation log.

The same manual describes CAN-connected I/O modules and I/O-Controller modules designated CMxxx-n, with supervision functions such as life guarding and node guarding. The CMPS designation follows this CM naming pattern, but the public manual we reviewed does not describe the CMPS itself, so its electrical data is not stated here.

Who Develops and Supports TEM Evolution

AVAT Automation describes itself as the developer and manufacturer of the TEM-Evo control system used on MWM gas engines. Caterpillar Energy Solutions, the owner of the MWM brand, announced a collaboration with AVAT to secure the long-term availability of spare parts for TEM Evo systems, with the Lorsch logistics centre acting as the spare parts hub.

For this reason, questions about module revisions, superseded numbers or firmware compatibility are best clarified with the engine's service organisation using the part number printed on the module label, 1247 0960KZ, together with the engine and genset serial numbers.

Cabinet Supply and CAN Wiring Reference

A DEUTZ wiring diagram for the TEM-Evo cabinet, dated 2006 and hosted on a third-party service site, shows the cabinet supplied with 24 V DC ±15 % with a ripple below 0.5 Vss, a typical average current of about 12 A and a 25 A protection device. Cable cross-sections of 6 mm² up to 12 m, 10 mm² up to 20 m and 16 mm² up to 33 m are listed for the supply cable. These figures describe the whole cabinet of that older generation, not the CMPS module alone.

The same diagram draws the CAN lines C_H, C_L and C_GD with a 120 Ω resistor and does not show the TRM1 and TRM2 terminals found on this module. Because the CMPS belongs to a later module generation, use the wiring diagram supplied with your own cabinet for termination, shield connection and supply values, and send us the engine serial number if you need help identifying the right spare.
