General HMG 4000
Edition 2016-03-08 - V01 R04 [7] Part No.: 669950
1 General
This manual is a constituent part of the device. It contains texts and graphics concerning
the correct handling of the product and must be read before operation of the device.
The manual offers information concerning the safe operation of the portable data
recorder HMG 4000.
By using this manual as recommended, you will ensure that the HMG 4000 is put into
effective and safe operation as quickly as possible.
1.1 Standard functions
The HMG 4000 portable data recorder is a mobile measurement and data gathering
device for measuring tasks for hydraulic and pneumatic systems and machines as well as
in industrial and mobile areas.
The applications are primarily to be found in the areas Service, Maintenance, Faultfinding or in the test bench area.
The HMI 4000 can record the signals of up to 38 sensors at once.
For this purpose, HYDAC ELECTRONIC offer special sensors, which are automatically
detected by the HMG 4000 and whose parameters such as measurement values,
measuring ranges and measuring units can be set.
On the one hand, there are the HYDAC HSI-Sensors (HYDAC Sensor Interface) for the
measurement of pressure, temperature and flow rate, for the connection of which there
are 8 analogue input channels.
Furthermore, there is the option of connecting HYDAC SMART sensors to these inputs.
SMART sensors can display several different measured variables at a time.
Up to 28 special HYDAC HCSI-Sensors (HYDAC CAN Sensor Interface) can be connected
additionally via the CANbus port, also supporting automatic sensor detection.
HMG 4000 can optionally be connected to an existing CAN network. This enables the
recording of measured data transmitted via CAN bus (e.g. motor speed, motor pressure)
in combination with the measured data from the hydraulic system.
Older model HYDAC sensors or commonly available sensors made by other
manufacturers can also be used. However, these sensors do not have any automatic
sensor detection, consequently the initial set-up has to be entered manually.
General HMG 4000
Edition 2016-03-08 - V01 R04 [8] Part No.: 669950
The device also offers measurement inputs for standard sensors with current and voltage
signals.
The HMG 4000 rounds off the application, providing two additional digital inputs (e.g. for
frequency or rpm measurements).
The HMG 4000 can render up to 100 measurement channels in total.
Depending on the type of sensor, there is an internal memory in the sensor for the
storage of recorded measurement data on a long-term basis. In addition, depending on
the sensor type, pre-set parameters can be changed and stored in the internal memory
as a sensor configuration.
The operator can intuitively access all of the unit’s functions and settings by means of
clearly presented selection menus. The HMG 4000 has a touchscreen similar to that of a
mobile phone or tablet computer for the purpose of entering number values and text.
When taking measurements of rapid, dynamic machine processes, all 8 analogue input
signals can be recorded simultaneously at a rate of 0.1 ms.
This function of course requires suitable fast sensors to be used.
The most impressing feature of the HMG 4000 is its ability to record the dynamic
processes of a machine in the form of a measurement curve and render them as a graph
— and, moreover, online and in real time.
The HMG 4000 is equipped with specially developed software providing for fast data
collection and processing. A measurement curve can comprise
up to 8 million measured values. The measured value memory for archiving this data can
record more than 500 measurement curves of this type.
Alongside simple measurement curves for single and endless recordings, the HMG 4000
has additional functions for recording event-controlled measurements and event logs.
There are various trigger options available for triggering events.
General HMG 4000
Edition 2016-03-08 - V01 R04 [9] Part No.: 669950
Alongside measurement curve recording, it is possible to create and save user-specific
settings, so-called user profiles. The main advantage of this is to enable identical
measurements of various equipment items to be repeated for the purpose of preventive
maintenance. All the user has to do is retrieve the relevant user profile from the HMG
4000’s memory.
For visualisation purposes, the HMG 4000 has a fully graphic-enabled 5.7" touchscreen
for displaying the shown measured values clearly as text or as a measurement curve. A
very large format display of individual measured values is also possible in order to be
able to read them from greater distances.
The HMG 4000 is equipped with numerous user-friendly functions for displaying,
evaluating and processing measured values:
• Table
• Graphics
• Scaling
• Tracker
• Zoom
The HMG 4000 communicates with a PC via the integrated USB device interface.
For the subsequent easy editing, display and evaluation of the measurements on a PC,
you can use the HMG 4000's "HMGWIN" software which is included in the scope of
delivery. This also permits the (remote) control of the HMG 4000 directly from the
computer.
The HYDAC software CMWIN is also supplied as standard with the unit. This software
enables you to communicate directly from your PC with SMART sensors connected to the
HMG 4000.
1.2 CAN functions
• Port option to CAN bus
• Read-out and evaluation of up to 28 measured values from up to 28 CAN messages
• Configuration of CAN sensor measured values
• Connection of up to 28 HYDAC HCSI sensors
• For further functions, see "CAN Tools" menu
1.3 Programming function for electronic switches
Programmable electronic print, temperature and level switches with IO link (EDS 8xx /
ExS 3xxx) as well as the HPG P1-000 can be easily programmed and parametrised via the
programming function of the HMG 4000.

7.1.5 Resetting measured value
zero point
You can re-specify the zero point via
the button.
This function can be used, for
example, in order to hide any
pressure heads in a system. In case
a pressure transducer still has, for
example, 3 bar of pressure even
when the system is switched off,
this value can be used as the new
zero point for the display.
Using the button, you can
delete the zero shift.
Re-zeroing can be done at any point throughout the measurement range of a
measurement channel.
Measured values HMG 4000
Edition 2016-03-08 - V01 R04 [25] Part No.: 669950
For safety reasons, all measurement
channels for which the zero point
was reset will be highlighted in the
measured value display with a
corresponding symbol.
Caution!
A high pressure may still be present in a measurement channel marked by
an arrow even though the display shows 0 bar.
When removing a sensor or other system components make sure the
system has been depressurized first.
Failure to do this may pose a hazard to life and limb.
Switching ON/OFF the HMG 4000 or
one or more measured channels does
not lead to the automatic deletion of
the newly set zero point.
If you switch the HMG off and on again,
you will receive a corresponding
message.
There is one exception where the null shift is automatically deleted. This happens
when a sensor is connected to the channel and this sensor has a different
