5 No other programming tools are required. Refer to page 15for operating 2: A PC computer interface using the S20-14131 Interface program, VDOS,and a portable S20-14131 program is DOS based and is compatablewith Windows and Windows are several benefits to using this The control parameters can be entered and stored on disk, even when not connect-ed to the VENUS Multiple setup files can be saved to The configuration can be retrieved from VENUS for backup The same setup file can be used for multiple VENUS the VGRAPH program, the input command, feedback signal and error can be dis-played on the computer screen similar to that of a strip chart recorder. As the systemperformance is being displayed in real time, the tuning variables of Proportional Gain(Kp), Integrating Gain (Ki) and Integrating Rate (KIT) can be dynamically adjusted toget the optimum system configuration data is stored in a non-volatile memory card inside VENUS .

7 Using a 24 Volts for12V coils may result in an over current shut down which may cause the power supplyoutput to brown out and reset commands can be voltages, current loops or potentiometers. Multiple inputs arepermitted and are selected by the Main / Auxiliary input. The input command can alsobe programmed internally as a LOCAL COMMANDset digitally using the S20-14125hand held terminal or with a PC computer using the S20-14131 devices can be incremental optical encodes, passive and active magneticpickups, DC tachometers, DC voltages or current loops, hydraulic flow meters, poten-tiometers, pressure, load and torque transducers, and current transformers for horsepower limiting.(12-24 VDC Isolated Inputs with isolated GND on terminal 32)Voltage must be applied to this input to enable the Controller s a voltage to terminal 28 will cause the Controller to accept the input com-mand from the Auxiliary input instead of the Main 1 is the default selection, applying a voltage to terminal 29 will select Ramp option is used to set the output to zero at the rate set by the Soft Stop Time.

8 Thisoption can be enabled or disabled through the system configuration. When enabled,terminal 30 must be energized to allow the system outputs to function. De-energizingterminal 30 will engage the soft stop function. When disabled, terminal 30 may be a voltage will cause the Controller to reverse the input command, with+5 VDC input command and coil A output energized the new input will become -5 VDCwhen reverse command is asserted and energize coil B output . VENUS can sense Horse Power in 1 of 2 ) Measure the electric motor ) Anti-stall - measure the prime mover s output shaft speed, diesel ) Electric Motor horsepower and electric motor current are directly related. HP ismeasured using a current transformer which is rated as a ratio of input current tooutput signal, 125:1, 125:20mA or 125:10 VDC meaning that for an input cur-rent of 125 AmpsAC the transformer output will be 1 AmpAC, 20mADC or output of the current transformer is fed into the VENUS Controller and com-pared to the adjustable limit.

9 When the measured HP exceeds the pre-set limit thecontroller will de-stroke the pump as a function of the HP Limit ) The prime mover s shaft speed, typically a diesel engine, is measured as a fre-quency and compared with the adjustable limit, as the HP requirements increasethe prime movers RPM decreases. When the shaft speed drops below the limit, VENUS will de-stroke the pump as a function of the HP Limit gain. VENUS has only1 frequency input, the user must decide which function it will serve, the systemfeedback or the HP GeneratorsOutputsHigh Level OutputsVenus has two independently adjustable ramps. Ramp 1, when selected (defaultramp), has adjustable up and down ramp times of to 90 seconds. Ramp 1 up andramp 1 down can be enabled or disabled independently, also Ramp 2, when selected (12 to 24 VDC applied to terminal 29) has its own up and downramp time adjustments of to 90 seconds and ramp 2 up and ramp 2 down can beindependently enabled or.

10 Using the S20-14131 PC interface program the Ramp 1 and Ramp 2 times to 300 ramp can be configured in one of two different types of ramp models as VENUS Controller has three outputs, one high current (coil A & coil B), one low volt-age and one low high current output stage is a two channel PWM driver with current feedback forprecise control of the current through the coil regardless of changes in coil channels are protected against short circuits across the coil and to following is a list of DENISON s hydraulic actuators that VENUS can control one of the following selections using the S20-14125 terminal or the S20-14131 PC software will automatically configure the Controller for the maximum currentand PWM frequency required by the stroker 12V or 24VF5 CFlow control valveVP01 Pressure control valve4RP01 Pressure control valve3DP03 Proportional directional valve (open loop) 12V or 24V3DP06 Proportional directional valve (open loop)
