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
responsibility for any accidents caused by incorrectly mounted or
incorrectly maintained equipment. The manufacturer assumes no
responsibility for the system being incorrectly applied, or the system
being programmed in a manner that jeopardizes safety.
Safety

viii VMM3120
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.

User Guide ix
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.

User Guide 1
The Vansco Multiplex Module (VMM) 3120 is a software-programmable,
multiplexing, input/output controller that monitors dedicated and general-purpose
inputs, and controls solid-state-switch outputs.
The VMM modules can be configured to meet many system requirements through
I/O configuration options and ladder logic software.
Figure 1: VMM3120
The VMM3120 is designed to communicate through a J1939-based Controller
Area Network (CAN). Custom CAN messaging can be created in software, and
the VMM3120 can be used in any CAN 2.0B application.
The VMM3120 is controlled by ladder logic software.
You can write the software in ladder logic using the Vansco Multiplex
Module Software (VMMS) tool. Contact your Parker Vansco Account
Representative for more details about the VMMS.
The VMM3120 has many features, as follows
The VMM3120 can monitor up to 34 inputs:
15 digital inputs
1. About the VMM3120

2 VMM3120
About the VMM3120
10 analog inputs
4 frequency inputs (2 AC, 2 DC)
2 power control inputs
3 digital inputs (active-low inputs used for harness addressing)
The VMM3120 has 20 outputs, rated at 2.5 A maximum current:
16 high-side outputs
4 low-side outputs
The VMM3120 has two Ampseal connectors (2 x 35 pin, keyed) that are used
to interface with the inputs, outputs, and CAN
The VMM3120 has 3 LEDs that can be used to indicate the status of inputs,
outputs, power, and CAN
The VMM3120 can detect and log the following faults:
Short-circuit
Overcurrent
Open load
Short-to-battery
Short-to-ground
This manual describes the hardware components of the VMM3120, but does not
explain how to write or configure the software. For more information about
software, refer to the appropriate software manual or contact your Parker Vansco
Account Representative.

The following is a high-level overview of the steps involved with this section:
1. Gather the required materials.
2. Install the required software tools provided by Parker Vansco.
3. Connect the VMM3120 to a development system (desktop) and power it up.
4. Download application software.
2.2. Gather Required Materials
The following materials are required for the procedures in this section:
VMM3120 multiplexing module
personal computer (PC)
controller I/O board
controller I/O harness (connects the VMM3120 to the controller I/O board)
evaluation kit power harness (connects the controller I/O board to the power
supply)
Data Link Adapter (DLA) kit (comes with cables needed for connecting the
DLA to your PC and to the rest of the system)
desktop power supply compatible with the VMM3120 and controller I/O
board loads (a 12 V DC, 3 A fixed voltage supply is generally suitable, unless
driving more significant loads)
procurement drawing for the version of VMM3120 you are using, indicating
the configuration options for your variant of the product.

7. Connect the DLA to a personal computer via the USB port.
2.4.1. Power Up the Development System
To power up the VMM3120 multiplexing module:
1. Ensure that all controller I/O board digital inputs, jumpers, and dip switches
are properly configured for your module type. Refer to the Controller I/O
Board Reference Manual for further details.
2. Ensure that the power wire (RED) on the controller I/O board is not
connected to the power supply (refer to the Controller I/O Board Reference
Manual for details).
3. Turn the power supply on.
4. If using a variable power supply, set the voltage to a value between 10 to 28 V
DC.
5. Turn the power supply off.
6. Connect the power wire (RED) on the connector I/O board to the power
supply.
7. Turn the power supply on.
Note: If an input e.g. INPUT_1 is configured as a power control input, you
must turn on the corresponding digital input switch on the controller I/O board
(e.g. Digital Input 1). Refer to the Controller I/O Board Reference Manual for
further details.

2.5. Create and Download Ladder Logic
Applications
Software applications can be created and downloaded to the VMM3120
multiplexing module.
The software applications for the VMM3120 can be created with the Vansco
Multiplexing Module Software (VMMS) tool, using ladder logic.
Consult your Parker Vansco Account Representative for information about your
software programming options.

10 VMM3120
Inputs
The VMM3120 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 VMM3120. If an inductive
load must be connected to an input, use a protective diode or transorb.
3.1. Digital Inputs
Digital inputs are typically used with electrical signals and switches that are either
on or off.
There are four types of digital inputs in the VMM3120:
Programmable Digital Inputs
Digital Inputs
Power Control Digital Inputs
Addressing Digital Inputs
3.1.1. Digital Inputs
The VMM3120 has 15 digital inputs:
INPUT3_D through INPUT19_D (INPUT11_D and INPUT14_D are not used)
Note: INPUT1_D and INPUT2_D can also be used as standard digital inputs as
long as they are not being used for power control.
