Operating Manual

3 Safety recommendations to be complied with General behaviour when handling the system The centralized lubrication system, pump or single components may be used only in awareness of the potential dangers, in proper technical condition, and according to the information in these installation instructions.

Familiarize yourself with the functions and operation of the product. The specified assembly and operating steps and their sequences must be observed.

Any unclear points regarding proper condition or correct assembly/ operation must be clarified. Operation is prohibited until issues have been clarified.

Keep unauthorized persons away from the centralized lubrication system.

Precautionary operational measures and instructions for the respective work must be observed.

Responsibilities for different activities must be clearly defined and observed. Uncertainty seriously endangers safety.

Safety-related protective and emergency devices must not be removed, modified or affected otherwise in their function and are to be checked at regular intervals for completeness and function.

Remedy occurring faults in the frame of responsibilities. Immediately inform your superior in the case of faults beyond your competence.

Do not reach into the system during operation.

Wear personal protective equipment always.

When handling lubricants observe the relevant safety data sheets and operating instructions by the lubricant manufacturer or supplier.

Never use parts of the centralized lubrication system or of the machine as standing or climbing aids.

Explosion protection Always behave so that fire and explosion hazards are avoided.

A written work approval from the operator is required prior to working in potentially explosive areas.

There must be no indications that parts of the explosion protection are missing or are not working. Should such indications become apparent, switch off the machine and inform a superior without delay. Keep unauthorized persons away.

Measures for explosion protection must never be deactivated, modified or bypassed.

LEC / en / Edition: 10/2017

It is forbidden to bring in ignition sources such as sparks, open flames and hot surfaces in potentially explosive areas.

Check the machine at regular intervals for damage which may represent an ignition risk.

The ignition temperature of the lubricant must lie at least 50 K over the maximum admissible surface temperature of the components.

Only use tools and clothing which are permitted for use in potentially explosive areas (ESD).

Transport, installation, repairs and work on electrical components may only be carried out, if it has been ensured that the atmosphere is not potentially explosive.

Operating Manual

Repairs or modifications to machines which are protected against explosions may be carried out only by the manufacturer or by a workshop recognized by a named institution and confirmed in writing.

If the work is not carried out by the manufacturer, the repairs must be approved by a named expert and confirmed in writing. The repairs are to be marked by a repair sign on the machine, stating the following: o Date o Executing company o Type of repair o If applicable, expert's code Transport damages can result in the loss of the explosion protection. If transport damages can be seen, do not assemble the machine or put it into operation All parts of the earthing concept must be correctly available and connected with the superordinate machine.

If transport lugs are dismantled after set-up, the threaded bores must be permanently sealed in accordance with the protection class.

Handle the materials so that no sparks are generated by tilting, falling, sliding, rubbing, impacting, etc. If needed, cover materials with suitable means.

Never disconnect plug-in connections when energized. Secure plug-in connections against inadvertent manual disconnection with the safety clips included in the delivery.

The operator must check critically whether operation without a low-level signal might lead to a new risk potential (e.g. through heat-up of bearing points on the machine in the area of ignition temperature, poor lubrication or bearing damage). If this cannot be ascertained, provide a low-level signal or suitable organisational measures for monitoring of the bearing point temperature.

Avoid dust accumulation and remove dust immediately. Dust accumulations have a thermally insulating effect and, if whirled up, generate the formation of a potentially explosive atmosphere.

The pump should be integrated into the operator's lightning protection concept.

All parts are to be checked regularly for corrosion. Replace the affected parts.

Operating Manual If transported separately (e. g. repair) lift the motor by means of the transport lugs or eye bolts. Ensure that transport lugs or eye bolts are firmly seated. Do not carry any further load on the transport lugs or eye bolts. Do not transport motors on the fan cover.

Assemble the pumps and other components only outside of the operating range of moving parts, at an adequate distance from sources of heat or cold.

Dry wet, slippery surfaces.

Cover hot or cold surfaces accordingly.

Prior to performing work, de-energize and depressurize the pump and secure it against unauthorized switch-on. Work on electrical components must be carried out by electrical specialists only. Observe any waiting periods for discharging, if necessary.

Carry out electrical connections only according to the information in the valid wiring diagram and taking into account the relevant regulations, the local connection conditions and legal prescriptions (e.g. DIN, VDE). Electrical connections must be done in such way that no forces are transferred to the product (tension-free connection).

Do not touch cables or electrical components with wet or damp hands.

Maintenance and repair work can be subject to restrictions at low or high temperatures (e.g. changed flow properties of the lubricant). Therefore, where possible, try to carry out maintenance and repair work at room temperature.

Carry out all works on electrical components using adequate, voltage insulated and technically proper tools only.

Fuses must never be bridged but have to be replaced by the same type of fuse always.

Determine the cause of the failure of the fuse.

Ensure correct earthing of the electrical system.

Undertake drilling at non-critical, non-load bearing parts only. Use any available boreholes. Do not damage lines and cables when drilling. It is essential to observe the machine manufacturer's installation instructions and to consult the machine designer in case of doubts.

Observe possible abrasion points. Protect the parts accordingly.

Other units of the machine or vehicle must not be damaged or impaired in their function by the installation of the centralized lubrication system.

Operating Manual

Observe the specified tightening torques. When tightening, use a calibrated torque wrench.

When working with heavy parts use suitable lifting tools. If need be, consult the responsible safety officer.

Avoid mixing up or wrong assembly of dismantled parts. Mark these parts accordingly.

Laying of the lubrication lines When laying the lubrication lines, observe the following information in order to warrant troublefree function of the entire centralized lubrication system.

CAUTION Environmental pollution Lubrication lines must be absolutely leakproof. Lubricants may pollute ground and waters. Lubricants have to be handled and disposed of properly. Observe all applicable prescriptions and laws regarding disposal of lubricants as well as the relevant safety data sheets.

Slipping hazard Centralized lubrication systems must be absolutely leakproof. Leaking lubricant is hazardous due to the risk of slipping and injury. During assembly, operation, maintenance and repair of centralized lubrication systems watch out for leaking lubricant. Leaks must be sealed immediately.

Dimension the lubrication line according to the maximum pressure and the output volume of the pump unit used.

Starting from the pump unit the main lubrication line should be laid preferably rising with a possibility to vent it at the highest point of the lubrication line system.

Mount the lubricant metering devices at the end of the main lubrication line in such way that the outlets of the lubricant metering devices show upwards. If lubricant metering devices have to be mounted below the main lubrication line, then this should not be done at the end of the main lubrication line.

The tube lines, hoses, shut-off and way valves, fittings, etc. have to be laid out according to the maximum operating pressure of the pump unit, the admissible temperatures and the lubricants to be supplied. Furthermore, the lubrication line system must be protected against inadmissibly high pressure.

Before the assembly thoroughly clean all components of the lubrication line system like tube lines, hoses, shut-off and way valves, fittings, etc. In the lubrication line system no seals should protrude towards the inside, as the lubricant flow could be impeded and contaminations could enter the lubrication line system.

The lubricant flow in the lubrication lines should not be impeded by the installation of sharp elbows, angle valves and check valves. Provide unavoidable changes of the cross sections in the lubrication lines with as smooth transitions as possible. Avoid sudden changes of direction, if possible.

The pistons inside the injectors are operated via lubricant pressure. A premetered amount of lubricant is dispensed to the connected SSV. After all injectors have operated, the pressure in the main line rises until the preset pressure on the pump is reached 240 bar. The control unit stops the pump via the pressure switch B69. The pump stops running and the relief valve is deactivated at the same time. The compressed lubricant in the main line can flow back into the reservoir, the pressure drops. When the pressure has fallen below 80 bar the pistons inside the LM5 injectors return to their initial positions by means of spring force and reload the adjustable amount of lubricant by this action.

The pause time can start and the system is now ready for another lubrication cycle.

Operating Manual 9.2.3 Single-line system The single-line system consists of a pump to supply lubricant under pressure to the injector metering devices via the supply line. The injector metering devices deliver lubricant to a secondary (progressive) metering device or to the bearing through feed lines.

The lubrication cycle is initiated by an automated pump. The injectors have indicator stems, which move in and out to indicate that they have been cycled.

A controller will control the automated system.

LEC / en / Edition: 10/2017

The time between on cycles and the length of off cycles is adjustable. The controller includes the timer function above with a monitor function and alarm capability. A pressure switch is used to indicate when system pressure has been reached to turn off the pump and verify that a lube cycle has been completed. If the pressure switch does not detect full pressure within a preset period of time, the controller goes into alarm state.

The only useful information is the low level quantity of the pump P3 reservoir.

If required, the operator can force the greasing cycle: for details refer to the respective data sheets.

NOTE! DAILY:

DO A VISUAL CHECK OF THE RESERVOIR FOR GREASE LEVEL

Operating Manual

11 Inspection and Maintenance DANGER! DANGER! – Do not carry out any repair works while the system is pressurized – Grease: Relieve system from pressure by carefully opening a fitting and/or the manual vent valve(s) if installed (option) – Hydraulic Oil: Relieve hydraulic system from pressure as described in the Operator Manual – Warning: Lubricant may spurt out while system is under pressure.

NOTE! Regular inspection and maintenance intervals are prerequisites for the proper functioning of the centralized lubrication system over a longer period of time. Any claim for warranty or liability will be null and void, if the prescribed maintenance intervals are not adhered to.

Please observe the following regular inspections and maintenance works: Daily: Visually check the lubrication points with regard to leaking lubricant Visually check the hose connections with regard to leaks and abrasions Check movement of indicator pins: During the lubrication time the pins have to retract, in the pause time all pins have to be extracted.

Weekly: Visually check of tube fittings with regard to leaks Determine the time required for one lubrication cycle. If the determined time deviates much from the usual lubrication time, check each single component (pumps, metering devices, tube lines).

Every 1000 operating hours: Clean or replace strainer assembly Clean or replace lubricant filter (refilling) Check the oil level in the crankcase of the pump model FlowMaster (if applicable) at the dip

LEC / en / Edition: 10/2017

stick Every 2000 operating hours: Change the oil in the crankcase of the pump model FlowMaster.

Use SAE 10W30 motor oil in all units used in an ambient temperature between –40° to 65°C. For ambient temperatures between 10° to 21°C uses Mobil Aero HFA low temperature oil.
