1 Bosch Rexroth Oil Control S.p.A. Via Leonardo da Vinci, 5 Società Unipersonale I Nonantola (MO) Tel Fax October 2016 Subject: NEW PROPORTIONAL POLE TUBE Ø23 AND NEW PROPORTIONAL COILS FOR EDC-P, ED4- P, ED4-PT,ED4-PTC AND LC1-P FAMILIES Dear Customer, We would like herewith to inform you that we have redesigned the Bosch Rexroth Compact Directional Valve Solenoid-Proportional Tube and Coil, Ø23, in order to offer to our customers a standardized solution across our product range. The New Tube-Coil upgrade fits market requirements and it follows a harmonization process among all DCOC product lines. 1. Listed in the following table are the product families involved in this change. Both Family Name and Reference Ordering code will change accordingly: Old family name Old product code New family name New ordering code EDC-P L8580_ EDC-P1 L8581_ ED4-P L8480_; L8080_ ED4-P1 L8481_; L8081_ ED4-PT L808003P_ ED4-PT1 L808103P_ ED4-PTC L808003C_ ED4-PTC1 L808103C_ LC1-P L5180_ LC1-P1 L5181_ 2. The implementation of this upgrade refers to: New improved Pole tube of 23mm diameter, please see the following pages for detailed info New improved Coils for better performance, please see the following pages for detailed info Please take note that Old and New versions are NOT interchangeable i.e. you can only use new coil with new pole tube. Please take note that with this change a new ring nut, and new ORs will be introduced with new material numbers. 3. Performance improvements for the Coil and the Pole Tube: With the new solution, the ambient temperature working condition range, for the valve, has been extended as follows: from -30 C to +90 C (old was -20 C to +50 C) (Please refer to the following pages). Moreover, The new Tube-Coil is more compact than the old one; the width is reduced by 7mm. See below. STAMP1010_2010 Capitale sociale i.v. C.F. e n.

6 MAIN DIFFERENCES BETWEEN OLD AND NEW DESIGN 1. Amp Junior Connector is now offered only with horizontal position as shown in below picture OLD DESIGN NEW DESIGN D15 Amp Junior Coil GP45 -- Amp Junior Coil 2. Characteristic control curve for 24VDC would be as follows: OLD DESIGN 24VDC COIL NEW DESIGN 24VDC COIL Max. Current Value = 0.88A Max. Current value = 1.2A Same behavior, same relative % values, Same behavior, same relative % values, but different regulating points but different regulating points Example for EDC-P: Example EDC-P1: 30%*0.88A= 264mA 30%*1.2A= 360mA
