General information OEM responsibility The OEM of a machine or vehicle in which Danfoss products are installed has the full responsibility for all consequences that might occur. Danfoss has no responsibility for any consequences, direct or indirect, caused by failures or malfunctions.
The system operates with high pressure fluid. Assembly and disassembly of the pump for maintenance purposes is only to be carried out by Danfoss or a qualified service technician authorized by Danfoss. Installation of the pump and electrical equipment must be carried out by suitably qualified personnel with experience and knowledge of working with hydraulic and electrical systems.

The DPC12 offers different modes for controlling the pump and to aid in system startup. Parameters are used to set the behavior of the DPC12 and are selected through use of the Danfoss PLUS+1 ® Service Tool and diagnostic file (P1D).
Not all limits can be applied together or with the principle control modes. The specific valid combinations depend on the software version. Refer to the Software Manual for details or contact your Danfoss representative for available combinations. Other features...

A load-sense pressure signal is required from a pressure sensor in the load-sense resolving network of the service if Load-Sense Mode is used. The proportional gains and integration time are tuned via non-volatile parameters. Contact your Danfoss representative for details on tuning these parameters.
® ® Communication occurs over the CAN bus and a CAN gateway such as the Danfoss CG150 is required. The diagnostic file allows parameter changes which select the control mode, limits, tuning gains, and other features. These parameters are saved in non-volatile memory. There are also pages to interact with Commissioning Mode and to see past and active Errors.
After the action type is chosen, action type specific interfaces will be available on screen. To exit Commissioning mode, press the Exit Commissioning Mode button, then follow the prompts. For more information on Commissioning Mode parameters and interaction, contact your Danfoss representative.

Do not directly or indirectly strike the coupling or driveshaft of the pump as this may cause internal damage. Do not drop the pump. If dropped, do not use the pump and contact your Danfoss representative. There are three handling brackets on DDP096 pumps. One bracket is on one side of the housing (pumplet 1) and the two other brackets are opposite of each other on the endcap at the rear of the pump.
The installation locations and position of the pump must be as described in this document. Adhere to all limits specified in the DDP096 pump specifications section regarding pressure, temperature, viscosity and cleanliness of the hydraulic fluid. Other configurations are possible; please contact your Danfoss representative for direction.
Contact your Danfoss representative for more support. Special control methods are recommended for systems with multiple DDP units connected in parallel to the same hydraulic load.
Suction strainers can have similar effects. If you plan to use a suction strainer, discuss it with your Danfoss representative. Return line filtration is the preferred method for open circuit systems. Consider these factors when selecting a system filter: •...
To reduce resistive power losses, the power supply cable to the DPC12 controller should use the maximum wire gauge the connector can accept (2 mm or 14 AWG) and be as short as possible; the maximum length should not be longer than 10 meters, contact your Danfoss representative otherwise Caution Avoid accidentally connecting incorrect pins to supply power.
3. Compare expected discharged flow with actuator speed, or flow measurement. If issues persist, contact Danfoss for assistance. Do not attempt to disassemble the pump. The pump is not field serviceable and special tools and procedures are required for assembly and disassembly.
