EATON KBD/TG4V-5 Proportional Direction Valve Installation Guide

EATON KBD/TG4V-5 Proportional Direction Valve

KBD/TG4V-5, Series 11

This product has been designed and tested to meet specific standards outlined in the European Electromagnetic Compatibility Directive (EMC) 2014/30/EU which repealed Directive 2004/108/EC. For Restriction of Hazardous Substances, complies to (RoHS) Directive 2011/65/EU. For instructions on installation requirements to achieve effective protection levels, see the Installation Wiring Practices for Eaton’s Electronic Products. Wiring practices relevant to this Directive are indicated by Electromagnetic Compatibility (EMC).

introduction

1. When supplied with 24V DC power, the Eaton™ “KB” range of proportional valves allow direction and rate of hydraulic fluid flow in a system to be controlled by a voltage or current command signal applied directly to the integral amplifier. It is not necessary to make any adjustments to the valve/ amplifier assembly prior to putting it into service either on a new installation or when replacing a valve on an existing installation.

2. WARNING
   This valve with its integral electronic amplifier was factory tested prior to dispatch for conformance to the cataloged specification and performance data but Eaton Hydraulics warranty may be nullified by such actions as:

3. Dismantling or adjusting of any part of the assembly other than may be indicated in this leaflet.

4. Incorrect installation.

5. Application of the valve outside its cataloged performance limits.

6. Incorrect electrical connections.

7. Incorrect electrical control signals

8. Before installing the valve, check that the model designation on the nameplate shows it to be the correct valve for the application
   

9. For further information

Valve for new application

1. Installation

2. The valve can be mounted in any attitude but the piping must be arranged to ensure that the valve is kept full of fluid at all times.

3. Do not remove the protection pad on the bottom face of the valve until immediately before installation. Take care not to lose the seals from the valve ports. Ensure that the surface on which the valve is to be mounted is clean and free from burrs and damage. This applies also to any intermediate “stacking/sandwich” valves that may be used.

4. Install the valve and any intermediate “stacking/ sandwich” valve on the mounting surface and secure them with bolts to class 12.9 (ISO 898) or better. Torque bolts according to the following recommendations. For details of available Eaton™ bolt kits see catalog 2314A “Fixing bolt kits”
   Clamping Height = 30 mm (1.18 in)
   Bolts/Studs for ISO 4401 = 4 x M6-6g
   (Torque to 17-20 Nm)
   Bolts/Studs for
   ANSl/B93.7M = 4 x 1/4”-20 UNC·3A
   (Torque to 13-15 lbf ft)
   Minimum actual bolt lengths are the sum of relevant clamping heights plus the minimum engagemant lengths in ferrous materials – see the table below:

5. Electrical connections
   Before starting to connect cables ensure that all power is switched off.
   Electrical connections must be made via the 7-pin plug mounted on the amplifier.
   The recommended cable should have at least 6 cores with pairs of conductors individually screened and an overall braided screen.
   A suitable cost effective cable is ALPHA type 1299/10C 10 conductor, 22 AWG foil shielded cable with drain wire. To achieve the recommended wire gages for the power supply and protective earth ground connections, pairs of wires are used.
   The minimum power supply voltage under full load conditions should be as shown in the following graph.

Command signals and outputs

WARNING

To conform to the requirements of the European Community directive on Electromagnetic Compatibility (EMC) the valves with integral amplifiers must be fitted with a metal plug. Suitable plugs are:

1. Eaton™ part no. 934939 which also gives environmental protection to IP67 when tightened with a torque of 2-2,5 Nm (1.5-2.0 Ibf.ft).
2. ITI-Cannon part no CA 06 COM-E 14S A7 S (not available from Eaton Hydraulics) The plastic plug part no. 694534 is only suitable for use in a sealed electromagnetic environment or outside of the European Community

Plug assembly instructions
The metal 7-pin plug part no. 934939 must be used with this valve to achieve the full EMC specification
with this valve to achieve the full EMC specification. The assembly of the plug is as shown in the diagram.

Wiring connections

Ramp adjustment

1. The ramp adjustment feature is accessed by removing the amplifier lid.
   Note: Before adjusting the ramp setting ensure that precautions are taken to prevent static discharge from harming the amplifiar. Ensure that tho amplifier lid seal is not damaged or lost during adjustment.

2. In normal operation the amplifier status LED will flash, To activate the RAMP adjustment mode:

3. Select button

4. Ramp increase button

5. Ramp decrease button

6. Status LED – green

7. Store LED – red

8. Ramp increase/solenoid operation LED – green

9. Ramp decrease/solenoid operation LED- green Note: If you wish to exit the ramp adjustment mode without storing the ramp settings then switch off power to amplifier. The amplifier will return to previously stored settings.

10. When refitting the amplifier lid ensure that the seal is fitted correctly and is not damaged. The amplifier lid screws should be tightened to 0,7-0,9 Nm (6.20-7.97 lbf in).
