SUMMARY:  Power units: UPE 2

Add to Cart

The UPE 2 clamping and drive module constitutes a complete drive system which is delivered ready for connection. It is used for the hydraulic fluid supply of hydraulic circuits.

 

For reasons of thermal loading, the clamping and drive module is to be operated in short-time operation and intermittent operation. The duty cycle is to be selected dependent on the power output and the environmental conditions so that the maximum admissible operating temperature of 80°C is not exceeded.

 

The clamping and drive module basically consists of the aluminum housing, the pump (radial piston pump or external gear pump) and the oil-immersed motor. The stator of the oil-immersed motor is pressed into the aluminum housing. It leads the winding heat directly to the exterior wall of the aluminum housing.

 

For the installation, four through holes for the mounting screws have been provided in the tank bottom. The clamping and drive module is to be operated in vertical installation position.

 

Optionally, the UPE 2 clamping and drive module can be equipped with an electric oil level and oil temperature monitoring, a breathing filter and a complete hydraulic control (see 51144).

 

Attention!

The clamping and drive module may heat up during operation ⇒ Risk of injury!

Electric motor

The clamping and drive module is designed for the operating mode according to VDE 0530 (EN 60034) for short-time operation S2 and intermittent operation S3 within the nominal power. The electric motor complies with insulation class F and then complete clamping and drive module with protection class IP54.

The direction of rotation of the electric motor depends on the installed pump (in this connection refer to the “Technical data”).

Electro-magnetic compatibility of devices (EMC)

According to the “Act on the electro-magnetic compatibility of devices (§2, subsection 4)” and the EEA Directive, the clamping and drive module is no operationally reliable device. In order to prevent electro-magnetic interferences that might occur, interference suppression elements by Murr-Elektronik in 71570 Oppenweiler are recommended.

Level switch (option)

The level switch is used for the electric monitoring of the hydraulic fluid filling level. If the minimum oil level is reached, the contact opens and thus gives a signal to the control.

Commissioning notes

Check whether the clamping and drive module has been connected to the machine to be operated in a professional form (hydraulically and electrically). For the electrical connections of the motor, the washers and connection bridges that are included in the scope of delivery must be used. The electric motor must be protected by means of equipment with an overload relay. The later must be set to the nominal current that is specified on the name/rating plate. When installing the clamping and drive module at an external gear pump, you must imperatively observe the direction of rotation of the motor; see arrow indicating the direction of rotation.(Practical check: Switch on the motor briefly and check whether the pump delivery fluid.)(Optical check: Remove the ventilation filter at the tank cover, switch on the electric motor briefly and check the direction of rotation of the rotor shaft.) Only fill in the hydraulic fluid through a filter with the required minimum retention rate. The clamping and drive module must maximally be filled with hydraulic fluid until the dipstick is reached and/or to the lower edge of the cover. The clamping and drive module must in no case be operated without hydraulic fluid. Start up the clamping and drive module without load and allow it to run at zero pressure for some seconds in order to provide for sufficient lubrication. After bleeding the hydraulic control as well as the actuators by moving them back and forth several times or by opening available bleeding points, the hydraulic fluid in the clamping and drive module is to be refilled to the correct level. The clamping and drive module may only be operated within the permitted limits. It may moreover only be operated if it is in an unobjectionable condition. When carrying out any work at the clamping and drive module, the system must be depressurized and de-energized. Unauthorized conversions or modifications, which affect safety and function are not permitted. Existing protective devices must not be removed. The generally valid safety and accident prevention regulations must be observed and complied with.

 

Attention!

The clamping and drive module may heat up during operation → risk of injury!

The clamping and drive module may only be set, maintained and serviced by authorized, trained and instructed personnel.

In repairs, only original spare parts may be used!
