调节说明
如果额定值电压范围为5V，则应用时其内部稳定电压UST=5V 交货状态，电桥接入（其它可能的电桥位置，见5.1节）印刷电路
板安装到模组盒中，见6节
说明：外部输入的额定值电压不允许是负值！负电压将会使放大器产生误动作、毁坏放大器，在超过最大额定电压5、10、或
15VDC（根据桥路）时，所调节的电流Imin或Imax运行将不起作用，这就是说，它超过了所调节的极限值。
在导线长度超过3米时，应使用双绞线电缆，以减弱电磁干扰的发射，提高抗干扰能力。
输出所使用的最大电流Imax，不应长时间超过比例电磁铁所能承受的最大极限电流Ilim，否则有可能烧毁电磁铁。

MAIN BOARD1.SUPPLY VOLTAGE The proportional amplifier requires an external DC power supply.Adiode on theinput protects the board against a power supply connected with the wrong polarity.Because the amplifier is a DC/DC converter the current consumption is less thanthe solenoid current.Several amplifiers can be connected to one power supply,which then has to meetthe following requirement:P MAX=n x P1(P1=requirement for one board,n=number of boards connected in parallel).The DC voltage must be between20and32VDC.When the amplifier is used tocontrol a valve with a24V solenoid then a voltage supply at the top end of thetolerance band(at least>26V)is recommended.This is to ensure that thesolenoid has sufficient current at higher temperatures.B/D28=+V SupplyB/D30=0V SupplyZ2,Z32=Earth(necessary for EMV)There is a current compensating coil in the supply line,with the result that the0Vline of the supply voltage is not identical with the ground potential of the amplifier.For this reason no connection may be made between the0V line of the supplyvoltage and the analogue ground of the amplifier!2.REFERENCE VOLTAGES The reference voltages±15V and±10V(stabilised)are generated by a switchedmode DC/DC converter on the board.B2=+15V unstabilised approx.50mAB4=−15V unstabilised approx.50mAD2=+10V stabilised approx.10mAD4=−10V stabilised

amplifier has a stabilised24VDC supply for transducers,positionswitches etc.D6,D32=+24V stabilised approx.80mAB6=GND5FUNCTIONAL DESCRIPTION MAIN BOARD MAND INPUTFive different current and voltage signals can be connected to the proportional amplifier.This accommodates all the industry standard input signals.The com-mand input is set up as a differential input.Adaptation for the different input voltages and compensation for the different input currents is made by setting the DIP switches and jumpers (JP4and JP5)on the main board (see page 13)accordingly.It is essential that the correct jumper and DIP switch settings are made.If the jumper and/or DIP switch settings are incorrect then the amplifier will not be able to generate the correct output current corresponding to the commandsignal.D12=positive command voltageB12=negative command voltage3.1COMMAND INPUT WITHDIFFERENTIAL INPUT FUNCTIONBecause a differential amplifier can only work correctly when,for the input and feedback resistances,particular resistance combinations are selected (SW2/1...8),this amplifier can only be used as a differential input amplifier when it is set up for a 10V input signal.The diagram to the left shows the settings for a 10V input signal with differential input function.Jumper ”JP4“and ”JP5”must be open.DIP switches SW2/2&SW2/4must be closed(ON).SW2MAND INPUT WITHOUTDIFFERENTIAL

WITHOUTDIFFERENTIAL INPUT FUNCTION(continuation)3.2.40...+10V COMMAND SIGNAL Jumper ”JP4“and Jumper ”JP5“must be open DIP switch SW2/4must be closed (ON)!An input signal voltage of 0...+10V generates an output current of 0...l MAX A .This command signal is normally used when an external command signal potentio-meter is used.See also the description below:Command from external potentiometer (see 3.2.6)or external signal source (see 3.2.7).The input impedance is 200k ¸.SW23.2.5CUSTOMISED COMMAND SIGNAL Jumper ”JP4“and Jumper ”JP5“must be open DIP switch SW2/1must be closed (ON)!If a command signal voltage is used which does not correspond to any of the above values (for example 0...+15V corresponding to 0...+100%command signal)the appropriate DIP switch has to be correspondingly set and the resistor R83(see page 13)has to be calculated according to the maximum voltage level and fitted to the board.The value of the resistance is calculated as follows:R83=V IN x 20k ¸/V Example:Command signal 0...+15V.R83=15V x 20k ¸/V =300k ¸.The existing resistor must be then replaced with a resistor having the value calcula-ted as above.The input impedance is equal the new value ofR83.SW23.2.6COMMAND VALUE FROM AN EXTERNAL POTENTIOMETER As standard a 10k ¸command potentiometer (minimum4.7k ¸)should be used.This is then connected to +10V amplifier reference voltage (pin D2)and the GND (pin B6).The wiper of the potentiometer is connected to the command signal input (pinD12).3.2.7COMMAND VALUE FROM AN EXTERNAL SIGNAL SOURCE An external signal source can also be used as a command signal (for example a PLC analogue output).In this case the ground of the signal source and the ground of the control board (pin B6)must be connected and also the signal output con-nected to the command input (pin D12).The DIP switch must be set according to the maximum input command voltage.When the command signal value is to be used as a differential input then the exter-nal signal source must be connected to D12and B12.The DIP switch settings and the level of the command voltage must be set as described under ”Command Input with Differential Input Function”(page 6).FUNCTIONAL DESCRIPTION MAIN BOARD 84.DITHERThe proportional amplifier has a square wave generator.This dither signal is super-imposed on the command for the output current.Both signals together give the valve current.The superimposed AC-content of the current reduces the hysteresis and friction of the valve.The 4pole DIP switch SW6permits 1from 3preset frequen-cies to be selected.Important!Only one (1)DIP

setting see page 15,16.4.3DITHER AMPLITUDE The dither amplitude can,if necessary,be accurately set within the range 0...300mAby adjustment of the ”dither”potentiometer RTR5(see layout diagram page 13).The factory setting is listed on page 3(REFERENCE TABLE)Adjusting the potentiometer in an anticlockwise direction increases the amplitude and viceversa.SW65.MAXIMUM CURRENT RANGEThe maximum output current at 100%command signal value can be set by adjusting the SMD multi turn potentiometer RTR3on the main board.The adjust-ment using the SMD potentiometer should not normally be made by the customer.Caution:Wrong adjustments can cause malfunctions or serious damages at the proportional amplifier and the proportional solenoid.On the main board there is a 4pole DIP switch (SW3)with which the maximum current value can be selected (see layout diagram page 13).Important!Only one switch of SW3in the closed (ON)position.SW3/1=closed (ON)400mA SW3/2=closed (ON)800mA SW3/3=closed (ON)1600mA

functions.When an external voltage supply is used for digital control then it is essential thatthe0V of the voltage source is connected with pin B20(digital GND).When voltage isolation is not essential then the24VDC supply from the amplifier(pin D6or D32)can be used for the control.In this case it is essential however,toconnect pin B20(digital GND)to one of the pins Z28,Z30or B6(analogue GND).The permitted voltage level+V digital must be in the range+4VDC to32VDC.The current consumption is approx.5mAper input at24V.6.1STOP The stop input can be used to switch the amplifier on and off.This input is anormally closed contact,in other words when there is no voltage at the input the”Fail Safe”LED is on and the amplifier is in the”Stop”state.The ramp generator isbypassed and the output stages are switched off.B16=+V digitalB20=GND digital6.2RAMP OFF With this input the ramp function can be switched on or off.This input is a normallyopen contact,in other words only when a voltage is applied to the input,the LED”Ramp OFF”is on and the output current to the solenoid corresponds to thecommand signal without delay.B18=+V digitalB20=GND digital7.SENSOR INPUTS For open loop amplifier there are no sensor inputs available.8.CONTROL OUTPUTS For open loop amplifier there are no control outputs available.9FUNCTIONAL DESCRIPTION ANALOGUE SUB BOARD10The following functions are to be found on the analogue sub board!9.JUMPER JP1-JP2The signal at the command measuring point can be selected with these jumpers.Only jumper JP1or JP2may be closed!9.1COMMAND MEASURING POINT When jumper JP1is closed the signal after the ramp generator and the l MIN and l MAXsettings can be measured at the test socket”Command”.0...100%command value=0...–x V(x≤10depending on the l MIN and l MAX settings)When the jumper JP2is closed the signal after the first amplifier stage can bemeasured at the test socket”Command”.0...100%command value=0...–10V(independent of whether the command value to the amplifier is acurrent or voltage signal)TroubleshootingIn the event of a fault jumpers JP1and JP2can be used to identify the source of theproblem.If the jumper JP2is closed and when the command value is changed acorresponding change in the range0...−10V is observed at the test socket”Command”then the main board is operating correctly.If the jumper JP1is closed and it is observed that the signal at the test socket”Command”is affected when the l MIN or l MAX potentiometers are adjusted then it canbe assumed that the sub board is operating correctly.The fault can then only be in the final stage of the current control,the dither genera-tor or the PWM generator on the main board.9.2JUMPER JP3This jumper is for special functions of other valves or valve groups.If the amplifier isused with pressure valve P2(VP01B design),4VP01,4RP01or proportionaldirectional valve4DP02E,4DP03E,4DP06E then the jumper JP3must be closed.9.3JUMPER JP4,JP5,JP6,JP7,JP8These jumpers are for special functions for different valves or valve groups.Ifthe amplifier is used with pressure valve P2(VP01B design),4VP01,4RP01orproportional directional valve4DP02E,4DP03E,4DP06E the following jumperconfiguration applies:JP4=closedJP5=not closedJP6=closedJP7=not closedJP8=closed(see also jumper and DIP switch setting pages15,16).9.4CURRENT MEASURING POINT At this measuring point there is a voltage signal proportional to the current.1V‰1A±10%.9.5FEEDBACK MEASURING POINT For open loop amplifier there is no feedback measuring point available.FUNCTIONAL DESCRIPTION ANALOGUE SUB BOARD10.TRIMMINGPOTENTIOMETERS10.1l MIN SettingThe minimum output current and so the initial valve pressure or flow can be adjusted with the l MIN potentiometer.The range of adjustment for l MIN is between 0mA and 50%of l MAX .Clockwise adjustment of the potentiometer increases the l MIN value and vice versa.10.2l MIN Step FunctionThe l MIN step function is necessary when the valve current should be 0mADC (plus effective dither value,see reference table page 3)with a command of 0V.At 0V command there is no current to the valve.When the command is only slightly above 0V (approx.1.5%of the maximum command value)then the current jumps from 0to l MIN (see 10.1).10.3l MAX SettingThe maximum output current can be limited by adjusting the l MAX potentiometer.In this way it is possible to limit the maximum pressure or flow of the valve to a lesser value than the rated flow.The value of l MAX can be set in the range l MIN to 3000mA.Clockwise adjustment of the potentiometer increases the l MAX value and vice versa.l MAXl MIN1.5%100%Command11.RAMPS The amplifier has a ramp generator.Without the ramp function the output current follows the command signal directly.With two potentiometers the acceleration and deceleration rate can be separately and independently set up in the range 1....50V/s (±20%).Clockwise adjustment of the potentiometer reduces the acceleration time (more time for the pressure increase)and vice versa.1V/s corresponds to 10s ramp time for a command jump from 0to 10V.50V/s corresponds to 200ms ramp time for a command jump from 0to 10V.VV/sV/stTEST AND SET UP
