User Guide vi
Do not perform the procedures in this manual unless you are experienced in the
handling of electronic equipment.
Contact the manufacturer if there is anything you are not sure about or if you have
any questions regarding the product and its handling or maintenance.
The term "manufacturer" refers to Parker Hannifin Corporation.
Safety symbols
The following symbols are used in this document to indicate potentially
hazardous situations:
Danger! Risk of death or injury.
Warning! Risk of damage to equipment or degradation of signal
When you see these symbols, follow the instructions carefully and proceed with
caution.
General safety regulations
Work on the hydraulics control electronics may only be carried out by trained
personnel who are well-acquainted with the control system, the machine, and its
safety regulations.
Follow the manufacturer's regulations when mounting, modifying,
repairing, and maintaining equipment. The manufacturer assumes no

User Guide vii
Safety
Do not use the product if electronic modules, cabling, or connectors are
damaged or if the control system shows error functions.
Electronic control systems in an inappropriate installation and in
combination with strong electromagnetic interference fields can, in
extreme cases, cause an unintentional change of speed of the output
function.
Welding after installation
Complete as much as possible of the welding work on the chassis before the
installation of the system. If welding has to be done afterwards, proceed as
follows:
Do not place the welding unit cables near the electrical wires of the
control system.
1. Disconnect the electrical connections between the system and external
equipment.
2. Disconnect the negative cable from the battery.
3. Disconnect the positive cable from the battery.
4. Connect the welder's ground wire as close as possible to the place of the
welding.
Construction regulations
The vehicle must be equipped with an emergency stop which disconnects the
supply voltage to the control system's electrical units. The emergency stop must
be easily accessible to the operator. If possible, the machine must be built so that
the supply voltage to the control system's electrical units is disconnected when the
operator leaves the operator’s station.
Safety during installation
Incorrectly positioned or mounted cabling can be influenced by radio
signals, which can interfere with the functions of the system.

viii DPS70
Safety
Safety during start-up
Danger! Risk of death or injury. Do not start the machine's engine
before the control system is mounted and its electrical functions have
been verified.
Do not start the machine if anyone is near the machine.
Safety during maintenance and fault diagnosis
Before performing any work on the hydraulics control electronics, ensure that
▪The machine cannot start moving.
▪Functions are positioned safely.
▪The machine is turned off.
▪The hydraulic system is relieved from any pressure.
▪Supply voltage to the control electronics is disconnected.

6 DPS70
Inputs
The DPS70 has digital, frequency, and analog inputs.
Damage to equipment! Do not connect inputs directly to unprotected
inductive loads such as solenoids or relay coils, as these can produce
high voltage spikes that may damage the DPS70. If an inductive load
must be connected to an input, use a protective diode or transorb.
2.1. Analog Inputs
The DPS70 has 10 analog inputs, Analog Input 1 to Analog Input 10. All of the
analog inputs are biased to a midpoint with pull-up resistor. This allows them to
be used as a tri-state input.

2.1.2. Analog Input Configuration Options
All analog inputs are hardware configurable with an optional pull-up resistor to
+5V. The default configuration for all of the analog inputs has the resistor
populated.
2.1.3. Analog Input Installation Connections
The sensor supply along with the sensor ground are the recommended power feed
to external sensors. This will prevent system noise from affecting the analog input
signals.

Note: It is important that the sensor supply does not connect to another
power source external to the DPS70. The sensor ground should also not
be connected to any other ground on the vehicle.
2.2. DPS70 Frequency Inputs
There is one type of frequency input in the DPS70:
▪Direct coupled frequency input
Direct coupled frequency inputs are typically used to read pulse signals.
The DPS70 has 2 direct coupled frequency inputs:
▪Frequency Input 1 to Frequency Input 2

8 DPS70
Inputs
2.2.1. DPS70 Frequency Input Capabilities
Direct coupled frequency inputs allow you to read the frequency of external
signals that have a ground reference and no DC offset. These inputs are ideal for
use with hall-effect type sensors.

2.3. Digital Inputs
The DPS70 has 9 digital inputs:
▪Digital Input 1 to Digital Input 3
▪Digital Input 4 to Digital Input 9
All of the digital inputs have a 1.2 k resistor that provides the path for the wetting
current. The resistor is connected to ground or VBATT depending on the active state
of the input.
The DPS70 has 2 types of digital inputs:
▪Hardware configurable active-high or active low, Digital Input 1 through
Digital Input 9
▪Hardware configurable to be active-high "Wake-up input", Digital Input 1
through Digital Input 3
2.3.1. DPS70 Digital Input Capabilities
All digital inputs are hardware configurable as either an active-high input (with a
pull-down resistor), or an active-low input (with a pull-up resistor).

10 DPS70
Inputs
Digital Input 1 to Digital Input 3 can be configured as wake-up inputs. When the
unit is in inactive power mode and a high signal is applied to a digital input
configured as a wake-up input, the unit will enter normal operating mode and
begin to operate.
Note: A digital input that is configured as a wake-up input must also be
hardware configured as an active-high input (pull-down resistor) to
prevent the system from continuously remaining powered up.

2.3.2. Digital Input Installation Connections
A digital input is typically connected to a switch that is either open or closed.
When the input is active-low
▪When the switch is open, the pull-up resistor ensures that voltage exists on the
input signal, which will be interpreted by the DPS70 as inactive
▪When the switch is closed, the input is connected to ground, which will be
interpreted by the DPS70 as active

User Guide 11
Inputs
When the input is active-high
▪When the switch is open, the pull-down resistor ensures that no voltage exists
on the input signal, which will be interpreted by the DPS70 as inactive
▪When the switch is closed, the input is connected to battery voltage, which
will be interpreted by the DPS70 as active

2.4. Video Inputs
The DPS70 accepts 5 NTSC/PAL camera inputs via BNC video connectors on the
rear of the unit. Inputs #1 and #2 feed are multiplexed to the same input of the
video decoder. Video inputs 3, 4 and 5 have dedicated decoder inputs. Up to 4
video feeds can be shown on the display simultaneously.

Outputs
There are 2 types of outputs on the DPS70. There are two high-side outputs and a
5V sensor supply output.
▪High-side outputs
▪Sensor supply output
3.1. High-Side Outputs
The DPS70 has 2 high-side outputs:
▪High-Side Output 1 to High-Side Output 2
High-side outputs are used for switching voltages to loads using either a pulse
width modulated (PWM) signal, or an on/off signal. They can also test for various
fault conditions.
3.1.1. High-Side Output Capabilities
All high-side outputs come with internal flyback diodes that provide protection
when driving inductive loads.
▪When a high-side output is used as a PWM signal, a pulsed output signal is
provided by the DPS70, where the percentage of time that the output is “on”
vs. “off” is determined by the duty cycle of the signal. The duty cycle is
determined by the software
▪When a high-side output is used as an on/off signal, the output provides
battery voltage when in the “on” state (the software is responsible for
switching high-side outputs on and off)
