4 OPERATING SPECIFICATIONS I. General Operation Guide All Logan Hydraulic manifold assemblies are designed to provide optimum actuation pressure to Logan product. The Logan Hydraulic manifold assemblies are designed to operate ONE clutch assembly. Consult Logan Clutch Corp. for applications that require multiple clutch devices. The manifold assemblies are designed to be integrated into existing hydraulic systems and function provided continuous flow and pressure are present to the manifold assembly. The hydraulic manifold assembly includes several components that provide the functionality required to operate and monitor Logan product: 1) Pressure reducing / relieving valve: Factory preset to the maximum allowable pressure of the clutch assembly (typical settings are 120, 200, 320, or 435 psi). Excessive pressure is relieved to the T port. 2) Solenoid valve (12 or 24VDC): When energized this valve directs flow to the C port. Actuation pressure will remain at the C port as long as the solenoid remains energized. 3) Low pressure switch: Factory preset to a setting marginally less than the pressure reducing / relieving valve. The pressure switch ensures sufficient pressure is present so that optimum pressure is available at time of clutch actuation. Should the minimum pressure not be available at the pressure switch then the switch will remain in the open state and the solenoid cannot be energized. 4) Pressure gauge: This gauge measures the pressure at port C. The reading of this gauge indicates the pressure being supplied to the clutch assembly. 5) Test Point (equipped on some models): Used to validate the incoming pressure to the manifold assembly (pressure at port P ). 6) Soft Shift Controller (soft-start option only): Electrical device used to control current to coil and enable softstart engagement of the clutch device. Factory preset to maximum time setting of 4 to 5 seconds. Field verification of proper adjustments required at initial start-up.! Caution! The solenoid coil located on the manifold assembly will operate HOT to the touch when energized for an extended period of time. 4

5 OPERATING SPECIFICATIONS II. Hydraulic Fluid Specifications 1) Recommended fluids: Mineral based or synthetic hydraulic oils with lubricating properties at viscosities of 7.4 to 420 cst (50 to 2000 sus). 2) Ensure that the hydraulic oil that is used is not contaminated. Using an inferior hydraulic oil will cause a short life span, poor performance, and possibly many malfunctions. 3) A 20-micron (or better) filter element must be installed in the supply line before the manifold assembly, to minimize abrasive wear on components. 4) Optimum oil selection should be determined by OEM of the equipment. For Logan hydraulic manifold and clutch devices and based on normal operating conditions an ISO Grade 32 hydraulic oil is acceptable.! Caution! Logan Clutch Corp. recommends the filter location to be on the supply line, not on the return to tank line (Port T ). When using a filter on the return to tank line maximum back pressure must not exceed 5 psi (0.3 Bar). III. Optional Operating Specifications Optional operating specifications are available for the Logan hydraulic manifold assemblies such as alternative pressure settings and low pressure switch settings. These settings are dependent upon specific applications. Consult Logan Clutch Corporation for requesting alternative settings. 1) Check Valve Feature - a check valve can be installed in lieu of the hex-head SAE o ring plug found in the manifold assembly. The purpose of the component would be in the event that momentary hydraulic pressure is not available to port P of the manifold assembly during desired clutch device operation. When installed the actuation pressure will be checked between the low pressure switch and clutch device (port C ). The clutch can be disengaged when using this feature by de-energizing the solenoid coil. Contact Logan Clutch Corp. to review application if feature is desired. 2) Soft Start Feature - for applications that have a relatively large inertia to engage or in which the clutch must be engaged at speeds above normal engine idle. 5

9 INSTALLATION INFORMATION I. Installation Requirements 1. It is important to bleed air from the manifold assembly and associated hydraulic hoses after initial installation. Carefully loosen fittings at junction C and TP on the manifold and at the clutch device for several seconds while energizing the solenoid to bleed air from the system. Tighten all fittings and top off oil reservoir (if required) following this procedure. 2. Port Identification and Sizes Port P : Pressure inlet port, SAE o-ring port size 6 (9/16-18 UNF thread). See Installation Requirement #3 chart for pressure and flow requirements. Port T : Tank / Drain port, SAE o-ring port size 6 (9/16-18 UNF thread). This return line requirement is an unrestricted port back to tank. Do not install a filter element on this return line, as any back pressure exceeding approximately 5 psi (0.3 Bar for most Logan clutch units) will cause the clutch unit to disengage sluggishly, resulting in excessive heat and wear. Port C : Clutch port, SAE o-ring port size 6 (9/16-18 UNF thread). At this junction a hydraulic hose should be installed to the clutch device actuation port. 3.

Requirements may vary slightly depending upon the noted factors and specific clutch model. 4. Pressure Adjustment Procedure The hydraulic manifold assemblies are factory preset to optimum pressure allowance of Logan clutch devices. However, due to the viscosity of various types of hydraulic fluids and ambient conditions the pressure reducing / relieving valve may require adjustment to achieve a desired setting. Before making adjustments allow the equipment s hydraulic system to circulate and warm to normal operating conditions prior to energizing the clutch device and checking the output pressure. If an adjustment is required the following procedure can be followed: 1. Remove cap from pressure reducing / relief valve by using 5/16 hex wrench and supporting the valve body with a 1 wrench. 2. Insert a 3/16 hex wrench into cavity of valve and energize solenoid coil. Caution! Clutch will energize. 3. Turn hex wrench clockwise slowly to increase desired pressure to clutch or turn counterclockwise to decrease pressure. Reinstall cap onto pressure reducing / relieving valve.! Caution! Do not adjust the pressure reducing / relieving valve to a pressure that exceeds the maximum rated pressure of the clutch device without prior consent of Logan Clutch Corporation.
