COILS AND ELECTRONIC CONTROLS Series E Environmental Coils SERIES E COIL NUTS FOR VALVES WITH MANUAL OVERRIDE When ordering Series E coils for retrofit applications on valves with manual override, the coil nut (top nut) must be ordered separately, based on the specific model of the valve to be retrofitted. Additionally, valves with dual coils (SV08-47xM and SV10-47xM models) require a spacer to be installed between the two coils. The spacer must also be ordered separately. See page 3.400.6 for spacer information. 1" HEX 1" HEX 1" HEX Coil Nut Part No. 4526260 For the following valves: Coil Nut Part No. 4528150 For the following valves: Coil Nut Part No. 4527160 For the following valves: SV08-20M SV08-22M SV08-24M SV08-25M SV08-26M SV08-3xM *SV08-4xM SV10-20M SV10-22M SV10-24M SV10-25M SV10-3xM *SV10-4xM SV12-20M SV12-22M SV16-20M SV16-22M SV38-20M SV38-22M SV38-24M SV38-25M SV38-26M SV38-3xM SV38-4xM SV58-20M SV58-22M SV58-24M SV58-25M SV58-26M SV58-3xM SV58-4xM SV08-47xM SV10-47xM *For SV08-47xM valves, use Coil Nut 4528150 For SV10-47xM valves, use Coil Nut 4527160 DESCRIPTION OF SERIES E COIL RATINGS IP69K: Coils with Metri-Pack ® connectors (EY option) Coils with Deutsch DT04-2P connectors (ER option) The coil is protected against intrusion of dust and high pressure water wash at 1450 psi (100 bar) with the source located 4 to 6 inches (100 to 150 mm) from the coil. IP65: Coils with DIN 43650 connectors (EG option) Coils with Dual Spade connectors (ES option) Coils with Dual Lead Wires (EL option), and Coils with Leads and Weather-Pack ® Connector (EW option) The coil is protected against intrusion of dust and can withstand low-pressure water spray from a distance of 10 feet (3 meters). Thermal Shock Immersion Test: Coils with Metri-Pack ® connectors (EY option) Coils with Deutsch DT04-2P connectors (ER option) Known in the construction, agricultural and mobile equipment industries as a “thermal shock dunk test,” the coil is heated for 2 hours at 105°C, then immediately immersed into 0°C water for 2 hours. No water intrusion into the coil is allowed. This test is repeated for a total of five trials. The coil is then tested for operational standards.

® HYDRAFORCE Intro. to Electro-Hydraulic Control Technology ELECTRO-HYDRAULIC CONTROL Electronic Control Electronic control in mobile equipment can consist of the following: Inputs: Inputs can be defined as the user interface, and can consist of joysticks, potentiometers, an operator panel, or other input device. Controller or PLC: This is the brains of the electronic control. It processes the inputs and converts them into a defined output to the hydraulic system. The controller also can have the ability to receive feedback inputs from machine sensors and attenuate its outputs accordingly. The controller can be factoryprogrammed or have the ability to be user programmable to meet the specific needs of the application. Outputs: Outputs can be on/off voltage signals or proportional PWM signals to control the hydraulic valving. Communications: The controller can have the ability to engage in two-way communications with a bus system. Feedback Inputs: Can consist of pressure transducers, temperature sensors, flow sensors, velocity sensors or RPM sensors. When feedbacks are used the system is described as “closed loop.” Digital Digital signals vary in discrete steps or increments. A digital signal is normally in the form of a series of pulses that rapidly change from one distinct, fixed voltage level to another. A clock that displays the time in actual numerals that change in one-numeral increments is an example of a digital device. Accuracy in a digital device is generally higher than in an analog device. In digital systems, physical variables are represented by numerical values using the binary (base 2) number system. Electronic Control Platforms Some of the different forms that mobile electronics can take are described in the chart below. There is an increasing complexity and cost as the controllers move from singlefunction analog controls to complete complex digital control systems. Digital vehicle controllers offer a high level of sophistication by executing a programmed sequence of functions that constantly control all motion parameters. PLC—Programmable Logic Controller PLC’s were developed to replace the older “sequential relay circuits,” that were used for machine control. The PLC works by measuring its inputs and depending on their state, switching its outputs on or off. The user enters setup instructions, usually via software, that will produce the desired results. Because many of the controller’s functions are user programmable, a PLC has the versatility to be field-modified for changing applications or conditions. Some PLC’s have the capability to convert analog inputs, process them digitally, and produce analog outputs. PLC’s that do not have built-in converters require separate analog-todigital converters to convert the input. Analog An analog signal is an AC or DC voltage or current that varies smoothly and continuously. In an analog system, a physical variable is represented by a proportional voltage that varies in correspondence with the physical variable. Electronic circuits that process analog signals are called linear circuits. An example of an analog device is a traditional-style clock that has hour and minute sweep hands that rotate around the dial. It is very difficult to get a highly accurate time reading with this type of clock. The precision of the dial calibration is a limiting factor.
