Eaton 11 Series Installation And Start-Up Manuallines

Installation and start-up guidelines
Installation and start-up guidelines for Eaton
proportional valves with integral amplifiers
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Directive (EMC) 2014/30/EU which repealed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).
1. lntroduction
1.1 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.
1.2 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:
Dismantling or adjusting of any part of the assembly
•
other than may be indicated in this leaflet.
Incorrect installation.
•
Application of the valve outside its cataloged
•
performance limits.
Incorrect electrical connections.
•
Incorrect electrical control signals
•
1.3 Before installing the valve, check that the model
designation on the nameplate shows it to be the
correct valve for the application.

electronics see catalog V-VLDI-MC002-E1

2. Valve for new application
2.1 Installation
2.1.1 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.
2.1.2 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.
2.1.3 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
Bolts/Studs for
ANSl/B93.7M = 4 x 1/4"-20 UNC·3A
Minimum actual bolt lengths are the sum of relevant
clamping heights plus the minimum engagemant
lengths in ferrous materials - see the table below:

2.1.4 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.
