Company Headquarters and Sales/Service: Bijur Delimon International 20 Gateway Centre Blvd., Suite Morrisville, North Carolina USA Phone: (00) Fax: (1) Application This SureFire SLR lubricator is ideally suited for use in single-line centralized lubrication systems. In these systems, lubricant is being delivered in pulses and under pressure (pressure and relief cycles) through the main feed lines to resistance fittings (metering units or control units) located near the lube points of the machinery being lubricated. Every use beyond this type of application is not in accordance with the manufacturers intended purpose, and the manufacturer is not to be held responsible for any damages resulting from it. The corresponding risk is taken by the user only. Safety This Operators Manual covers fundamental concepts, which are to be observed for installation, operation and maintenance. Therefore, it is absolutely necessary that the Operators Manual be studied by the person doing the installation prior to installation and start-up. It is also necessary to have this Operators Manual nearby and available for reference in the future. The safety instructions mentioned in this Operators Manual, as well as all national operating and safety regulations for the safe operation of such equipment are to be observed. Precautions and symbols General precautions and symbols used within this manual are as follows: General safety instructions Electrical safety instructions Safety instructions which shall be considered for reasons of safe operation of the lubricator Electrical connections made to Earth ground are identified by this symbol Electrical connections made to the Neutral conductor are identified with a capital N Conditions and actions that pose potential hazards to the user are marked by this sign All safety and/or warning labels affixed to the SureFire SLR lubricator must be maintained in a completely legible condition. Also, any modifications made to the SureFire SLR lubricator (or to any of its components) must be approved by Bijur Lubricating Corp. prior to its use, otherwise the warrantee and any liability by Bijur Lubricating Corp. will be null and void. Design and Construction The basic design of the SureFire SLR lubricator is that of a motor driven gear pump, which sits in a reservoir of lubricant. The motor, gear pump and connecting driveshaft are assembled as a self-contained unit and are dropped into the reservoir through a hole in the main structural component, the Top Plate. Installing the motor and pump assembly into the reservoir from the top provides easy access to all of the motor and pump components, including the screen (if applicable) without having to disassemble the reservoir. If detaching the reservoir from the Top Plate is necessary, it can be done easily and without any tools on all models other than the 12 liter models, by loosening the external latches that are located on either side of the lubricator. On all models other than the 12 liter models, the Top Plate is mounted to the customer equipment by means of two bolts, and also provides the mounting locations for all of the other lubricator components. The 12 liter models are supported from the bottom. The motor, pump and driveshaft assembly delivers pressurized lubricant directly into a channel in the Top Plate. This channel is sealed by means of O-Rings, and gives the Top Plate two integral outlet ports, one located at each end. Therefore, the customer may connect the main line plumbing distribution network to either side of the Top Plate, or to both sides, whichever is more convenient or aesthetically pleasing. N 2

3 Principle of Operation When power is supplied to the motor (via either an on-board timer or controller or by customer-supplied power) the motor runs the gear pump. As the motor turns, the gear pump pulls lubricant in from the reservoir and delivers pressurized lubricant to the distribution network via the outlet(s) in the Top Plate. Pressurizing the distribution network forces all of the resistance fittings in the system to discharge the lubricant to the friction points. As the resistance fittings discharge, the pressure in the network continues to rise until the limit in the pressure switch is reached (pressure switch sold separately). Once this limit is reached, the pressure switch can be used to stop the motor. Once the motor stops, momentary pressure in the distribution network is greater than the pressure at the outlet side of the gear pump. This pressure differential actuates a quick dump valve which relieves the distribution line pressure back into the reservoir. In the SureFire SLR models that come equipped with an on-board timer or controller, the frequency of the cycling is programmed automatically to be either time dependent or machine event dependent (ex. triggered by a proximity switch). Also, if the pressure switch ever becomes faulty, any over-pressure situation in the distribution network is always relieved back into the reservoir by means of a pressure relief valve set at a level safe for Bijur resistance fittings. A low-lubricant level switch is standard on all SureFire SLR controller models as well, and is used to prevent operation of the lubricator once the level of lubricant in the reservoir falls below a set minimum level. In this case, the motor is prevented from running and a fault condition on the controller is generated and/or a fault light is illuminated. Also, on all SureFire SLR models that have an on-board controller, the pressure building aspect of the system is monitored to detect if there might be a possible leak in the distribution system. More specifically, the time elapsed from the motor start event to the pressure switch event is monitored, and if too much time is taken between these two events, a leak in the distribution network is assumed, the motor is subsequently prevented from running and a fault condition on the controller is generated and/or a fault light is illuminated. On all SureFire SLR models that have an on-board controller, once a fault condition is generated, it is cleared by the next successful lube cycle and pressure switch actuation. All SureFire SLR models come with an LED that illuminates when the motor shaft is actually turning, and a Momentary On/Off Switch that can be wired for manual priming if the customer so desires. For all SureFire SLR models that come with an on-board timer or controller, the Momentary On/Off Switch is pre-wired at the factory.

9 Installation and Commissioning Install the SureFire SLR Lubricator in the horizontal position ONLY. Attach the lubricator in the desired location and to the desired equipment by means of an appropriately sized bolt through each of the (2) mounting holes in the top plate. For the 1. and 2. liter models, use (2) M6 bolts. For the 6.0 liter models, use (2) M bolts. For the 12.0 liter models, support the reservoir from the bottom. Reservoir size Hortizontal distance between mounting bolts Use bolt 1. 15MM +5/ -0 M MM +5/-0, 2MM +5/-0 M MM +5/-0 M 12.0 The lubricator should be installed in a location that is easy to access, for purposes of viewing the front panels, for ease of reservoir-filling, for ease of service and for ease of attachment to the distribution network plumbing. Remember the SureFire SLR allows attachment of distribution plumbing to either (or both) sides of the top plate. If only one side is used, be sure to plug the unused outlet with a G1/ BSPP plug (one such plug is included with each lubricator). Also, the reservoir on the 1.L, 2.L and 6.0L models can be easily removed by loosening the latches located on ether side of the lubricator. However, to successfully do this, be sure to leave enough clearance underneath the lubricator to allow for the reservoir to be dropped down appropriately. Right view G 1/ BSPP (Min. 6mm O.D. main distribution line tubing recommended) Reservoir latch Two liquid tight fittings are supplied with the lubricator. Use the liquid tight fittings to secure the electrical wiring for the lubricator and to prevent ingress of fluids or dirt into the motor compartment. Typically one of the fittings is used to bring power into the motor compartment and the other fitting is used to bring signal into or out of the motor compartment. All electrical connections are to be made by a qualified technician and all local electrical codes are to be followed. When electrical connections are being made, do so before the power leads are connected and before the power is supplied. Consult the wiring diagram (located under the motor cover) for the correct wiring for your SureFire SLR lubricator. The installation should include a means of disconnecting the power supply for servicing. Such means shall allow for switching off the power during normal operation and/or in an emergency. Also, a residual current device is required to automatically disconnect the power supply in the event of a failure in basic insulation. Be sure that all plumbing distribution lines are clean, are not kinked and are free from any chips or any other impurities. Fill the reservoir through the fill cap and/or fill cap strainer with clean lubricant specified by the Original Equipment Manufacturer and that meets all of the lubricant specifications listed below. Lubricant viscosity Oil, cp Fluid grease, NLGI 000 to 00, ,000 cp Do not overfill the reservoir. Never fill past the MAX level as noted on the reservoir. Overfilling could cause damage to the electrical components located under the motor cover. Pump priming Filling the reservoir and turning on the lubricator is usually enough to prime the pump. However, in the case of a very thick lubricant, sometimes it s necessary to assist priming the pump. Upon initial startup, if no lubricant is being delivered to the pump outlet, make sure the pump is primed. Avoid all kinds of impurities as dirt particles are the most common cause of gear pump failure. If you wish to determine whether the lubricant you plan on using is approved for use with Bijur Lubricating Systems, you can consult the Customer Service Department. To prime the distribution network, plumb the entire system (mainline tubing, manifolds, junctions, air/oil blocks, resistance fittings, resistance fitting outlet tubing to bearing points, etc.). Then, remove a plug or resistance fitting at the point furthest away from the pump. Now, run the pump until bubble-free lubricant flows from this point. Replace the plug or last resistance fitting. All tubing, flexible hoses and fittings must be compatible with the lubricant, operating pressure and surrounding environment. In general, try to install the lubricator in the lowest position (vertically) with relation to the rest of the distribution network and do not allow the tubing to rise and fall when avoiding obstacles. This is in case air enters the distribution lines, the bubbles will tend to rise towards the end of the distribution lines and not get caught anywhere along the way.

10 Maintenance and Service The SureFire SLR lubricator does not require much maintenance. After initial set-up, the lubricator requires only the following maintenance: a) When filling the reservoir with oil, the lubricant must be poured through the oil-filler screen b) The oil-filler screen must be inspected after every or 5 fillings and cleaned if necessary c) If filling with a thin grease, due to the fact that SureFire SLR thin grease models omit the filter screens, be sure the grease is fresh, clean, and is not higher than 0,000 cp viscosity. d) Do not use aggressive cleaners to clean the lubricator. Use only mild cleaners or degreasers to clean the lubricator. In the event of having to replace a pressure gauge, do not remove the adapter from the top plate. Prevent the adapter from rotating with one wrench as you remove the old gauge and install the new gauge with a second wrench. Appropriate pipe thread sealant applied to the male thread of the new gauge is recommended. Troubleshooting Pre-mature wear of the gear pump and the other moving parts is usually caused by dirty or contaminated lubricant. Failure of the SLR lubricator to deliver lubricant can be caused by an incorrect commissioning sequence, resulting in either air or dirt being trapped in the distribution network. A permanently lit (red) LED, present on controller versions, is caused either by the lubricant level in the reservoir being too low, or the system not being able to build enough pressure to trigger the pressure switch, or both. In either case, the red light (fault) can be cleared by filling the reservoir and running the next pressure up/pressure relief cycle successfully. This is usually done by pressing the manual lube button. If you have any questions and need technical assistance, our Customer Service number is: Hydraulic Diagram ON/OFF Timer (optional) The ON/OFF Timer that came with your SureFire SLR Lubricator automatically controls the lubricator to be ON for the time you set and OFF for the time you set. Making the actual settings is covered below. The Timer is a very simple device and as long as power is continuously supplied, it continually cycles the motor of the lubricator ON and OFF based on the time settings you choose. Wiring The wiring diagram is shown on the next page. The Timer is wired to the lubricator motor at the factory. For the oil version, ignore positions -, and use all other positions for other lubricator functions as necessary. For the grease version, ignore positions -, and use all other positions for other lubricator functions as necessary. Also, always be sure to connect your power to terminals 1 and 2 on the Terminal Block as shown, being careful to keep in place any jumpers that were already installed at the factory. If you have a 115VAC or 20VAC model, the motor Duty Cycle is: S 20%, which means the maximum continuous ON time for any cycle is minutes, and if the motor continuous ON time is X, the required minimum OFF time for that same cycle is 5X. If you have a 2VDC model, there are no such maximum ON or minimum OFF time requirements. Time settings Making the ON and OFF settings on the Timer is very simple. The top two dials on the front face control the ON time (0.1 seconds to 0 hours), and the bottom two dials control the OFF time (0.1 seconds to 0 hours). For each pair of dials, the beige colored dial sets the time range for the setting, and the blue colored dial actually makes the setting. For example, if you desired your ON time to be seconds and your OFF time to be 5 minutes, you would set the upper beige dial to be 1- (seconds) and the upper blue dial to be, then you would set the lower beige dial to be 1- (minutes) and the lower blue dial to be 5. It s that simple. The Timer is working whenever power is supplied to it. If the power is interrupted, the Timer completely stops. Once the power is restored, the Timer begins again with whatever it s current ON time setting is. Also, to make lubricator adjustments easy, changes to the ON and OFF time settings can be made while the timer is running, and take effect at the beginning of the very next timed cycle. Please be aware of the motor duty cycle restrictions as previously noted. Bijur recommends that the lubricator be tested after making any time settings. This is to make sure the settings are correct before the pump is left to run in an unattended fashion.
