505.20/.30 HPU Functional Description Component Descriptions (Continued) Component Description Fluid Sample Port Access port for obtaining hydraulic fluid samples from the HPU. A quick disconnect port is provided. Use the optional sampling kit that includes a needle valve to regulate the flow through the sample port. Heat Exchanger Cools the hydraulic fluid by using an oil-to-water heat exchanger. The heat exchanger removes most of the heat generated by the HPU.
505.20/.30 HPU Functional Description Pressure The start/low/high switch on the electrical enclosure’s front panel controls the hydraulic pressure of the HPU. The start/low/high switch operates like an automotive ignition switch; turn and hold the switch in the start position until the motor starts running. The switch returns to the low position. The unit automatically starts in low pressure to reduce the amperage needed for starting, which will extend pump and motor life.
505.20/.30 HPU Functional Description The effective operating range of the auto-cooling circuit is between system pressures of 14 MPa (2000 psi) to 21 MPa (3000 psi). In order for the autocooling valve to function properly, it must be re-adjusted anytime the output pressure is changed and operation of the HPU at the new pressure is to be longer than 10 minutes. Note Electrical Control If the test condition requires a maximum pressure level less than 14 MPa (2000 psi), consult MTS.

General Safety Practices: Hydraulic Power Units and Safety General Safety Practices: Hydraulic Power Units and Hydraulic Service Manifolds The hydraulic power unit (HPU) provides high pressure hydraulic fluid to system components for system operation. The hydraulic service manifold (HSM) controls distribution of that hydraulic fluid pressure. This section provides general information about safety issues that pertain to system hydraulic supply and distribution components.
General Safety Practices: Hydraulic Power Units and It is very important that you study the following safety information to ensure that your facility procedures and the system’s operating environment do not contribute to or result in a hazardous situation. Remember, you cannot eliminate all the hazards associated with this system, so you must learn and remain aware of the hazards that apply to your system at all times.
General Safety Practices: Hydraulic Power Units and Have first aid available Accidents can happen even when you are careful. Arrange your operator schedules so that a properly trained person is always close by to render first aid. In addition, ensure that local emergency contact information is posted clearly and in sight of the system operator. Know potential crush and pinch points Be aware of potential crush and pinch points on your system and keep personnel and equipment clear of these areas.
General Safety Practices: Hydraulic Power Units and Practice good housekeeping Keep the floors in the work area clean. Hydraulic fluid that is spilled on any type of floor can result in a dangerous, slippery surface. Do not leave tools, fixtures, or other items not specific to the test, lying about on the floor, system, or decking. Protect hoses and cables Protect electrical cables from spilled hydraulic fluid and from excessive temperatures that can cause the cables to harden and eventually fail.
General Safety Practices: Hydraulic Power Units and Handle chemicals safely Whenever you use or handle chemicals (for example, cleaning fluids, hydraulic fluid, batteries, contaminated parts, electrical fluids, and maintenance waste), refer to the appropriate MSDS documentation for that material and determine the appropriate measures and equipment required to handle and use the chemical safely. Ensure that the chemical is disposed of appropriately.
General Safety Practices: Hydraulic Power Units and Know the causes of unexpected actuator motions Do not use RF transmitters Know compressed gas hazards The high force and velocity capabilities of MTS actuators can be destructive and dangerous (especially if actuator motion is unexpected).
Hazard Placard Placement Consult MTS when in doubt about the safety or reliability of any system-related procedure or modification that involves devices that contain any type of compressed gas. Hazard Placard Placement Hazard placards contain specific safety information and are affixed directly to the system so they are plainly visible. Each placard describes a system-related hazard.

505.20/.30 HPU Connections Connecting the controller cable Note If a controller is not used, the installed jumper plug must be used or the unit will not start. • The controller cable provides a means to connect your controller to the HPU. • The controller cable allows you to remotely start and stop the unit and switch between the low and high pressure selections. The controller cable also permits the controller to monitor the low level, over temperature, and dirty filter status.
505.20/.30 HPU Connections CAUTION The first time a pump motor is started after electrical service is connected to the HPU, it is possible for the pump motor to rotate in the wrong direction. A pump motor rotating in the wrong direction at high pressure for longer than 10 seconds can cause severe damage to your HPU. If the output pressure does not increase within 10 seconds after High is selected, stop the unit.
Position the 505.20/.30 HPU Position the 505.20/.30 HPU You should determine where to put the HPU. Becauseit is connected to the other hydraulic equipment through hydraulic lines, the HPU can be located anywhere. To position the HPU: • The HPU can fit through a standard 1-m or 36-in door. • The HPU can be moved by a fork lift, pallet jack, or dolly. • Placement considerations should include proximity to the facility electric power and the hydraulic components.
Precharging the Surge Suppressor Accumulator B. If the output pressure gage shows no pressure, press the Stop button to shut down the unit (do not run more than 10 seconds in the wrong direction). Have a qualified electrician make a change in the electrical phase to the motor. 6. Check for unusual noises or leaks. If a problem is found, press the Stop button. You must correct the problem before you continue. 7. Turn the High/Low/Start switch to the High position. 8.
Precharging the Surge Suppressor Accumulator 3. With an open-end wrench, turn the locknut counterclockwise on the accumulator valve assembly to open the valve. Read the pressure on the high pressure gage. • If the pressure reading is outside the range of 10.3–12.5 MPa (1500– 1800 psi), refer to the procedure on changing the precharge pressure. • If the pressure level is within the range of 10.3–12.5 MPa (1500–1800 psi), turn the locknut clockwise to close the valve and continue this procedure. 4.
Precharging the Surge Suppressor Accumulator 3. Install the valve stem cap and protective cover. Increasing pressure To increase the precharge pressure: 1. Close the locknut on the accumulator. 2. Open the bleed valve two turns. WARNING Precharging with a gas other than dry nitrogen will cause the existing nitrogen within the surge suppressor to be mixed with the new gas. Mixing gases can produce unpredictable results. Use only dry nitrogen gas to precharge the surge suppressors. 3.
Precharging the Surge Suppressor Accumulator Install the valve stem cap and protective cover. Close the valve on the nitrogen bottle. 38 Installation Model 505.20 - 505.

505.20/.30 HPU Controls 505.20/.30 HPU Controls The controls shown in this figure are described in the following table. Hydraulic Power Unit Control Power On Stop Low Level Reset Overtemperature Low High Start Hour Meter Dirty Filter 0000000 Front Panel Controls Control/Indicator Function Power On Indicates when power is applied to the HPU from the main electrical circuit. Low Level Indicates when the hydraulic fluid falls below a preset level.
Operating the 505.20/.30 HPU Locally or Remotely Control/Indicator Function Overtemperature Indicates when the temperature of the hydraulic fluid exceeds 55°C (131°F). Overtemperature will cause an interlock and turn the HPU off. The interlock signal can be monitored by your system controller. Dirty Filter Indicates when the filter needs replacement. A dirty filter condition will prevent the HPU from being started, but it will not stop the HPU while it is running.
Recovering from an Interlock 4. Turn the start switch to the High position to operate the HPU at full pressure. Note If the HPU generates an interlock during operation (low fluid level or high temperature), the HPU will be stopped. Once the cause has been corrected, press the Reset button before restarting. 5. To stop the HPU, press the red Stop button. Remote operation Remote operation can occur at a remote control panel or from your system controller software.
Changing the Water Flow 1. Check the temperature gage to ensure that the hydraulic fluid is actually overheated. If not, the overtemperature switch may need replacement. 2. If necessary, cool the hydraulic fluid as described in this section. 3. Determine if the hydraulic fluid is receiving adequate cooling. • The auto-cooling circuit provides a path for circulating hydraulic fluid through the heat exchanger during periods of high pressure operation with low demand by the system.
Resetting the Thermal Overloads Note When the HPU is turned off, a solenoid valve also shuts off the flow of water to the heat exchanger. The valve is adjusted at MTS Systems Corporation to maintain the hydraulic fluid temperature at 43°C (110°F). However, the temperature of your water may require you to readjust the regulator. Decrease Increase To set the operating temperature of the hydraulic fluid: 1. Start the HPU and switch to high-pressure mode. 2.
Resetting the Thermal Overloads A tripped thermal overload or a blown fuse indicates a potential short circuit, too much heat in the electrical box, or a component failure (mechanical or electrical). Transformer Fuses FU4—FU6 Line Fuses FU1—FU3 Thermal Overload To reset the thermal overload switches or replace the fuses: 1. Turn the main disconnect switch counterclockwise to remove power from the electrical control box. 2.
Adjusting the Hydraulic Pressure Adjusting the Hydraulic Pressure The output pressure can be adjusted from a low pressure value of 1 MPa (145 psi) to the factory setting of 21 MPa (3000 psi). If you have a special testing requirement, you can reduce the HPU output pressure. If you do so, you should also adjust the auto-cooling valve (described later).
Adjusting the Auto-Cooling Level 3. Monitor the hydraulic pressure gage located on the control manifold. Adjust the output pressure as follows until the desired pressure is displayed. • Turn the output pressure control clockwise to increase the pressure. • Turn the output pressure control counterclockwise to decrease the pressure. Note If this pressure level is to be used for longer than 10 minutes, proceed to Adjusting the Auto-Cooling Level. 4.
Adjusting the Auto-Cooling Level Adjusting the autocooling valve to correspond with a change in HPU output pressure Perform the following procedure whenever the HPU will be operated with a change in output pressure for longer than 10 minutes. The procedure assumes that Steps 1 through 3 of “Adjusting the Hydraulic Pressure” have already been completed. 1. With the HPU running in high, loosen the nut on the Auto-cooling Valve located on the control manifold. 2.
Adjusting the Auto-Cooling Level A. Decrease the HPU output pressure and note a decrease in pump pitch when the valve closes. At the point when the valve closes, the pressure on the gage will momentarily hesitate during the adjustment. B. Increase the pump output pressure to the desired pressure setting and note an increase in pump pitch when the valve opens. Once again the pressure gage will show a momentary hesitation when the valve opens. 5.
Adjusting the Auto-Cooling Level 3. Adjust the Auto-cooling Valve by slowly turning the valve counter clockwise. When the valve shifts, a sudden change in pitch will be heard from the pump. A. Reversing the valve adjustment a number of times will aid in identifying the proper setting. B. Make a final counter-clockwise adjustment, an increase in pump pitch will be heard that corresponds with the opening of the valve. C. Stop adjusting at this point. 4.
Low/High Pressure Functionality Low/High Pressure Functionality This section clarifies the low and high pressure functionality of the HPU. There are certain cases where it is advantageous to use the HPU in low pressure versus high pressure.
Low/High Pressure Functionality Once the HPU has cleaned the reservoir hydraulic fluid, sections of the system should be isolated and sequentially cleaned. Flushing of hard line sections takes place in high pressure mode. If the HPU is run in low pressure, flow losses in the system will minimize the external flow and reduce the effectiveness of the system flushing and fluid conditioning.
Low/High Pressure Functionality The effective range of the auto-cooling circuit is between system pressures of 14 MPa (2000 psi) to 21 MPa (3000 psi). In order for the auto-cooling valve to function properly, it must be re-adjusted anytime the output pressure will be changed for longer than 10 minutes. Note Model 505.20 - 505.30 SilentFlo™ HPU If the test condition requires a maximum pressure level less than 14 MPa (2000 psi), consult MTS.
