WarningsWarningsThe following Warnings are for the setup, use, grounding, maintenance and repair of this equipment. The exclamation point symbol alerts you to a general warning and hazard symbols refer to procedure-specific risks. Refer back to these Warnings. Additional,product-specific warnings may be found throughout the body of this manual where applicable.WARNINGEQUIPMENT MISUSE HAZARDMisuse can cause death or serious injury. Do not operate the unit when fatigued or under the influence of drugs or alcohol. Do not exceed the maximum working pressure or temperature rating of the lowest rated systemcomponent. See Technical Data in all equipment manuals. Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in allequipment manuals. Read fluid and solvent manufacturer’s warnings. For complete informationabout your material, request MSDS forms from distributor or retailer. Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only. Do not alter or modify equipment. Use equipment only for its intended purpose. Call your distributor for information. Keep children and animals away from work area. Comply with all applicable safety regulations.SKIN INJECTION HAZARDHigh-pressure fluid from dispense valve, hose leaks, or ruptured components will pierce skin. This maylook like just a cut, but it is a serious injury that can result in amputation. Get immediate surgicaltreatment. Do not point dispense valve at anyone or at any part of the body. Do not put your hand over the end of the dispense nozzle. Do not stop or deflect leaks with your hand, body, glove, or rag.

See Table 1, page 12.As long as lubricant is supplied under pressure to the inletsection of the divider assembly, valves sections will continue tooperate in a progressive manner. Divider assemblies alwaysfollow a constant discharge pattern. Whenever lubricant flowceases, the valving pistons will stop. When flow resumes, it willstart again at the same point in the discharge cycle.Component IdentificationValveSectionInletSectionA Series-Flo type divider valve is a manifold proportioningdevice consisting of an inlet and end section plus a minimumof three valve sections. The divider valve is manifoldedtogether with tie rods and nuts. A master divider valve is thefirst divider valve downstream from the lube pump. Asecondary divider valve is any divider valve receiving lubricantfrom the master divider valve.Valve Sections (MSP, MHP, MHH, ZMSP and MXPmodular-type, divider valves, only)Valve sections (three or more required per manifold) contain apiston specially fitted to that section, built in outlet check valvesand various passageways that, working with the piston, metersand valves the flow of lubricant (FIG. 2).PistonEnclosure/EndPlugEnclosure Plug GasketO-RingsIndicator/ Port PlugPistonCrossportPlateEnd PlugSubplates withOutput PortsCheckValveIndicatorPortIndicator Port PlugTI11102FIG. 2EndSectionTI11117Tie Rod NutFIG. 1312497AValve sections may be manufactured to require one or twolube outlets.

SetupPrefilling Lubricant Distributor Lines6.Follow the following procedure exactly as written, in the orderwritten.Repeat steps 1-5 for each of the other lube linesconnected to the other outlet ports in the secondarydivider valve assembly and for any other secondarydivider assemblies in the system.CAUTION The initial startup and operation is the most critical operating period for a newly installed machine in terms ofpotential for being damaged by unremoved/unfilteredlubricant contaminants and lack of adequate lubrication.Proper prefilling of lubrication system ensures that lubricant is immediately available to every lube point duringmachine startup, protecting them from damage.Use only clean oil filtered to the SAE -recommendedcleanliness level of ISO 18/14 (ISO Standard 4406) whenprefilling a system. The manufacturers of the machinetool and its component bearings should be consulted toensure that the ISO 18/14 cleanliness level is adequate.Do not replace any of the performance indicators or portplugs removed in Step 1 until the line-filling proceduredescribed in Section 2 (Filling Master -to-SecondaryLube Lines) has been completed.2.

RepairLocating and RepairingBlockagesBlocks will cause a higher than normal pumping pressure.Depending on the application or system design, this blockagewill usually result in a complete loss of lubricant flow into thetotal system and no bearing will be receiving lubrication.The loss of flow due to a blockage is first indicated with thehigher than normal system pressure that is developed by thepump as it attempts to overcome this blockage. Higherpressure is limited, isolated and signaled through the use ofvarious performance indicators, reset and relief, incorporatedinto the system design.Performance IndicatorsCAUTIONNever block a lube outlet that is designed to discharge lubricant.Rupture IndicatorRupture indicators are used on MSP/MH divider valveapplications where lube system pressure exceed 2500 psi.The high pressure from the lube line blockage causes a disc torupture. The lubricant then forces an indicator to protrude,locating the blockage. The high pressure backs up through thesystem and trips a switch to shut the system off. When thefault is corrected, the disc must be replaced and the pin resetmanually.Automatic Relief IndicatorAn automatic relief indicator pinpoints lube line blockage butallows the lube system to continue supplying lubricant topoints that are not blocked. They are used primarily insecondary divider valves. The excessive pressure created byline blockage moves a piston, enabling the lubricant to escapethrough a vent. When the pressure is relieved, the springresets the piston. Because these devices permit the lubesystem to keep operating when a lube point is blocked, aseparate pressure switch connected to an audible alarmshould be used to warn of high pressure.Performance indicators are pressure-sensitive devices thatpinpoint excessive pressure in the lubricating system.These devices are installed in the indicator ports of dividervalves, signal a fault either by causing an indicator pin toprotrude or by releasing lubricant into the atmosphere.Reset Indicator with MemoryReset indicators stop lube system operation when a faultoccurs. These devices can be used in either master orsecondary divider valves.When a lube line becomes blocked, the resultant highpressure pushes the indicator pin through the opening in thecap. The high pressure prevents the affected divider valvepiston from completing its cycle, causing a pressure backupthrough the divider valve which trips a pressure switchupstream from the valve and shuts off the pump.The indicator pin remains extended until it is reset manually.This helps locate the lube line that is blocked.312497A11
RepairLocating and Repairing Blockages4b. Master Divider Valve Equipped Without PerformanceIndicatorCAUTIONUse only clean oil filtered to the SAE -recommendedcleanliness level of ISO 18/14 (ISO Standard 4406) whenprefilling a system. The manufacturers of the machine tooland its component bearings should be consulted to ensurethat the ISO 18/14 cleanliness level is adequate.1.Make a visual inspection of the system. Check for crushedlines or improper divider valve installation.2.Verify that each divider valve outlet required to dischargelubricant can do so and that no pipe plugs have beeninstalled in an outlet designed to serve a bearing oranother divider valve.3.Use a manual pump with a gauge. Fill the pump withclean, filtered lubricant.
