Severalfrequency inverters can be connected to a choke/filter combination. When doing so, the sum of input currents must not exceed the rated/nominal current of the filter and/or the choke.Area of application:Frequency inverter SK 5xxE-550-340-A … SK 5xxE-222-340-A SK 2xxE-550-340-A … SK 2xxE-751-340-AIt is also possible to connect several frequency inverters to an appropriate filter.

It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.SAFETY AND GENERAL INFORMATIONSave these instructions. For your safety, read and understand the information contained within. The owner and operator shall have an understanding of this product and safe operating procedures before attempting to use this product. Instructions and safety information shall be conveyed in operator's native language before use of this product is authorized. Make certain that the operator thoroughly understands the inherent dangers associated with the use and misuse of the product. If any doubt exists as to the safe and proper use of this product as outlined in this factory authorized manual, remove from service immediately.Inspect before each use. It is recommended that, prior to each use, an inspection be done by qualified personnel and that any missing or damaged parts, decals, warning / safety labels or signs be replaced with factory authorized replacement parts only. Any pump that appears to be damaged in any way, is worn, leaking or operates abnormally shall be removed from service immediately until such time as repairs can be made. Any pump that has been subjected to a shock load (a load dropped suddenly, causing the system pressure to exceed 10,000 PSI), shall be removed from service immediately until checked by qualified personnel. Owners and operators of this equipment shall be aware that the use and subsequent repair of this equipment does require special training and knowledge.PRODUCT DESCRIPTIONThis Pump is engineered to meet most industrial standards for Performance and Safety. Its allows quick displacement of hy-draulic fluid under no load conditions and easy pumping in loaded conditions. This electric hydraulic pump supplies compressed hydraulic fluid to compatible single acting applications ONLY. Such applications include rams, presses, spreaders, compactors and crimping machines, anywhere that 10,000 PSI of single acting fluid pressure is needed. Special skill, knowledge and training may be required for a specific task and the product may not be suitable for all the jobs described above. Unsuitable applications would include applications that call for a device to move, level or support persons, animals, hazardous materials, mobile homes/ dwellings in general, mirrors and/or plate glass, and/or to connect/secure hatches, components, etc. between bulkheads. The user must make the decision regarding suitability of the product for any given task and assume the responsibility of safety for himself/herself and others in the work area.Figure 1 - Typical 3-way 3-position PE series Electric Pump Components (PE60M4N06J shown)Electric Motor ON/OFF SwitchControl Valve Electric MotorControl BoxControl Valve Lever Drain PlugReservoirPower CordOil Output PortsBEFORE USERead, understand, and follow all printed materials carefully before attempting to assemble or operate these pumps. NOTICE: E-Pumps are shipped dry. Add oil before use. Electrical Connections:Compare motor nameplate against power availabilityto prevent motor burnout and dangerous electrical overloading. The motors are wired for 380 volts unless otherwise specified.DANGER: Motor, connections and remote on/off switchare energized components containing line voltage.Ensure supply is grounded and GFI protected. Hydraulic Connections:1. Check oil level, add oil if necessary.2. Make sure system fittings and connections are tight and leak free.3. Place control valve lever in the middle (Neutral/Hold) position to prevent accidental lifting or moving of load.4. To start the motor: Toggle the ON/OFF switch located on the control box to 'ON' position OR for momentary use: Leave control box switch in the 'OFF' position and toggle remote ON/OFF pendant switch.5. It is recommended to use to ON/OFF switch at the control box to let the pump idle for a few minutes before putting into operation.WARNING: This pump is for use with a single acting cylinder ONLY! Connect one hose from either pump oil output port to the input port of a single acting application such as a cylinder. Block the unused output3. Remove vent cap on the top plate of the reservoir.4. Use a funnel to fill reservoir to about 2" from top of reservoir plate.5. Wipe up any spilled fluid and reinstall the vent cap.Changing Hydraulic Oil1. For best results, change hydraulic oil once a year.2. Remove drain plug, tilt the pump then pour used fluid into a sealable container.3. Dispose the hydraulic oil in accordance with local regulations.4. Fill hydraulic oil, then reinstall vent cap.CleaningClean oil filter screen periodically with nonflammable solvent, then blow dry before reassemble back to pump.Storage1. When not in use, depressurize and disconnect hydraulic hoses from application.2. Wipe clean, thoroughly.3. Store in clean, dry environment. Avoid temperature extremes.4. For transportation or long term storage, shield pump with a protective cover.TROUBLESHOOTINGA system failure may or may not be the result of a pump malfunction. The following information is intended to be used as an aid in determining if a problem exists. Pumps should be repaired only be repaired by authorized BVA Service Center.MAINTENANCE1. Keep areas around pump unobstructed in order to provide good air flow around the motor and pump. Try keep the motor and pump as clean as possible.2. Inspect hoses and connections daily. Replace damaged components immediately with BVA Hydraulics replacement parts only.3. Tighten connections as needed. Use non-hardening pipe thread compound when servicing connections.4. Check hydraulic oil level every 40 hours of operation. Add hydraulic oil if necessary.5. Completely change the hydraulic oil every 300 hours of operation. Change the oil more frequently when pump is used in an extremely dusty environment or when the oil has been overheated. Use only good quality hydraulic oil. We recommend BVA hydraulic oil (F01 & F05), ISO 46 or equivalent. To order the oil, refer to service parts section. Use only the manufacturers recommended hydraulic oil. Use of other hydraulic oil may result in pump failure and will void warranty.Adding Hydraulic Oil1. Make sure electric motor is OFF.2. Depressurize and disconnect hydraulic hose from application.SymptomPossible CausesCorrective ActionMotor will not start• No power or wrong voltage • Damaged power cord • Tripped circuit breaker • Loose or faulty wiring• Check the power supply & voltage • Contact Customer Service• Ensure electrical supply is adequate • Contact Customer ServiceErratic cylinder action • Air in system or pump cavitation • External leak• Internal hydraulic leak • Follow pump instructions for bleeding air • Tighten all connections • Contact Service Center Pump fails to maintain pressure• External leak• Internal hydraulic leak• Pump or valve malfunction• Tighten all connections • Contact Service Center Cylinder extends partially• Hydraulic oil level too low in pump • Load is above the capacity of system • Cylinder is sticking or binding • Fill and bleed the system • Use the correct equipment • Contact Service CenterCylinder moves slower than normal • Loose connection or coupler• Restricted hydraulic line or fitting • Pump not working correctly • Cylinder seals leaking • Tighten• Clean and replace if damaged• Check pump operating instructions • Replace cylinder Cylinder leaks hydraulic fluid • Worn or damaged seals• Replace cylinderCylinder will not retract or retracts slower than normal• Loose couplers• Weak or broken retraction springs • Cylinder damaged internally • Pump reservoir too full• Tighten couplers • Replace cylinder • Replace cylinder• Drain hydraulic fluid to correct level Motor cuts out• Extension cord too long • Faulty motor• Overheated motor trips circuit breaker• Replace• Replace or repair• Allow motor to cool, reset circuit breakerParts List Service PartsINCLUDES MODEL NUMBER: PE60M3N06J & PE60M4N06JSFA Companies 10939 N.
