10 Hydraulic power unit Device description 3.1 Operation Principle The hydraulic power unit generates pressure required for the operation of the brakes. Via a coupling (Item 1), the electric motor (Item 24) flanged to the housing, drives the gear pump (Item 8) providing a constant discharge rate. Simultaneously, the housing (Item 20) serves as a completely enclosed stable oil reservoir. The gear pump carries the hydraulic medium against a pressure via a one-way flow control valve (Item 30) and to pressure connection P1. Via connection P1 the consumers are connected to the unit. A medium returning from the consumer is returned to the tank via tank connection T1. A one-way flow control valve (Item 31) prevents the medium from exiting via connection T1. Pressure setting The pressure of the hydraulic power unit is set gradually via the pressure relief valve (Item 29). The permissible maximum pressure must not exceed 100 bar. At the time of the delivery, the pressure relief valve is set to 95 bar. The operating pressure can be read at the pressure gauge (Item 28). Pressure switch The pressure value set must be monitored via a pressure switch (Item 26). Operating and connection instructions see data sheet. Temperature and level controll The temperature of the hydraulic oil is monitored via two independent temperature switches (Item 23 and Item 16). The maximum permissible temperature value of the hydraulic medium is 60 C. Simultaneously, the temperature switch Item 23 serves as the level controller. For the delivery, the level controller is provided with a default setting. For the oil filling, the oil level control as well as the temperature control of the medium and shut-down of the pump motor see Chapter 4.2 Instructions on Explosion Protection e /Electrical Connection and Chapter 4.3 Putting into Operation and Operation For operating and connection instructions of the temperature and level switch see data sheets. Hand-operated pump The hydraulic power unit can be operated without a motor via a hand-operated pump (Item 15) connected to the housing by pipes. The hand-operated pump delivers 30 cm³ per stroke.

Fill in the hydraulic medium until the liquid begins to rise in the filling neck without overflowing. The optimal liquid level is 5cm below the upper edge of the filling neck. The maximum oil quantity is 26 litres! Do not overfill. Due to the position of the filling neck, during filling a required air reservoir of at least 10% of the filling quantity remains to prevent an impermissible pressure increase when heating occurs! Always fill with clean oil! Use filling filter of the filter mesh size MIC10 (10μm). Ensure cleanliness! MBA tz Hydraulic power unit TZ60; Status: 03/01/11 Index: a Page 11

13 Hydraulic power unit Installation Permissible installation situation: horizontal installation, +-5 maximum. This is the only installation situation, in which the hydraulic pump is constantly under oil and thus outside an explosive atmosphere. Connect electrical components (motor, pressure switch, temperature- and level controller). Observe data sheets. Check supply voltages. Check the motor s direction of rotation: For this, start the motor briefly and adjust the direction of rotation according to the data sheet / direction of the arrow on the motor. An extended operation of the motor with an incorrect direction of rotation will damage the pump. Start the motor. Now the hydraulic pump carries oil against pressure. Factory setting = 95 bar Use the pressure gauge (Item 28) to check the pressure. The pressure is adjusted via the pressure relief valve (Item 29). Attention! Do not exceed the maximum operating pressure of 100 bar. Connect consumers (valve control cabinet and brake). Connect the consumers to pressure pipe P1 and tank pipe T1. Threaded connection P1: 12 l Threaded connection T1: 12 l During installation, ensure utmost cleanliness. Pipelines and hoselines must be cleaned and rinsed in advanced. After the filling and ventilation, refill the hydraulic medium until the filling level in the filling neck starts to rise. The optimal level is 5cm below the upper edge of the filling neck. (see Refilling). Do not overfill! Close the screw plug afterwards. The system is ready for operation. Alternatively, the hydraulic power unit can also be operated via the installed handoperated pump. For this purpose, attach the hand lever of the hand-operated pump, which is included in the delivery.
