2. INSTRUCTIONS FOR SAFE OPERATION
≡2 Instructions for safe operation
2.1 General
• Carefully read, understand, and follow the instructions and specifications listed in this document be-
fore operating the device. Failure to comply with these instructions or operation of the device outside
the intended field of operation may result in serious damage to machinery and may seriously affect
the safety of users. TTControl cannot be held liable for any personal injury or property damage re-
sulting from improper installation or use of the device, non-compliance with the instructions in this
document, or non-compliance with the intended field of operation. Non-compliance will result in the
exclusion of any liability and warranty.
• Different regulations and standards may apply to the off-highway machinery, depending on the use
and field of operation. Ensure that the Vision 312 device fulfills all requirements and standards for
the intended use and field of operation by comparing with the TTControl Declaration of Conformity,
Road Certification, and Summary of Compliance Test Documentation of the corresponding Vision
312 devices.
• Always operate the product within the electrical and environmental specifications and follow the han-
dling and mounting instructions provided by TTControl. Usage of the product outside the specifica-
tions may be hazardous to persons or property.
• Only skilled and trained personnel are allowed to operate this device.
• The device must be stored, handled, and installed carefully.
• The surface of the device can reach high temperatures. Ensure that there is enough heat dissipation
on the back side of the device. Avoid touching the metal parts of the housing.
• High sound pressure levels! Avoid getting close to the device loudspeaker when using at high vol-
umes.
• Choose a location for the display that prevents ergonomic hazard to the user, and adjust the monitor
position to minimize reflections and reduce glare.
• Do not use hard, sharp, or spiky objects to operate the touchscreen as this will damage the protection
glass.
• The protection glass surface shall be kept clean of abrasive particles (e.g. sand, metal swarf) at all
times. Operation of the touchscreen with abrasive particles will roughen the surface. Over time this
will affect the visibility of the display as it will render the screen dull and fuzzy.
• The device must be mounted and operated using the type of connectors specified in this document.
• The label on the housing contains important information. The label must not be destroyed or made
unreadable.
• All firmware, bootloaders, or CODESYS runtime environments used with the device must be au-
thorized by TTControl. Any modifications made to the firmware, bootloader, or CODESYS runtime
enviroment must be authorized by TTControl.
• The device hardware does not require maintenance activities.
• The device is delivered with a protection foil. This foil is intended for transportation and handling
purposes. We highly recommend removing this foil from the device at incoming goods inspection.
• Check regularly if updated versions of this document or additions to it are available.

2. INSTRUCTIONS FOR SAFE OPERATION
2.2 Intended use
The Vision 312 family products are programmable and robust visualization and operator interaction units,
to be used for parameter-setting and operation in vehicles and mobile machinery for construction, agricul-
tural, forestry, and municipal applications.
2.3 Improper use
• Opening and/or modifying the device is not permissible. Failure to comply may result in serious
damage to machinery and may seriously affect the safety of users, or reduce the lifetime or operability
of the device. Opening the device will result in the exclusion of any liability and warranty claims.
• Operation of the device in an environment that violates the specified range is not permissible.
• Use in explosive areas is not permissible.
• Any use of the product other than as described in section 2.2 is considered to be improper.
• TTControl is not liable for damages resulting from improper use.
ATTENTION!
The device must not be used for safety-critical tasks!
2.4 Checks to be done before commissioning the device
• Check the supply voltage before connecting the device.
• Check that the device connector and the cable harness are free of defects.
• Check the correct dimensioning of the wires in the cable harness.
• Always disconnect the power supply before conducting any maintenance or repair work to the ma-
chine where the device is mounted (for example, welding or maintenance of the battery system).
• Choose a mounting location for the device so that the operating temperature of the device does not
exceed the maximum allowed operating temperature.
• A protective fuse must be installed between the vehicle’s battery and the power supply input (BAT+)
of the device.
• The device is water-resistant according to IP6K5. Ingress protection is given only when all connectors
are plugged in, or the device has blind plugs installed.
• Refer to the MRD [2] for further guidelines and instructions.
2.5 Disposal
Disposal of the device must be performed in accordance with prevailing national environmental regula-
tions.

4.1 Regulatory information
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference re-
ceived, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant

interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

6.2 Negative power supply (BAT-)
6.2.1 Pinout
Connector Pin no. Function
C1 1, 2 Battery power supply input (BAT-)
6.2.2 Functional description
The pin for negative power supply. Always use all pins on the connector to distribute the current load.
6.2.3 Maximum ratings
Symbol Parameter Min Max Unit
IBAT-max Permanent supply current at VBAT- = 8 V, 25 ○C 2.3 A
6.3 Ignition on switch input (Terminal 15)
6.3.1 Pinout
Connector Pin no. Function
C1 18 Terminal 15 Input
6.3.2 Functional description
Terminal 15 switches the power supply of the Vision 312 device.
6.3.3 Power on/off sequence
The device boots if
• Terminal 15 is powered (typically BAT+) or
• Wake-up input is powered (typically BAT+)
Once the device has started, the application software is responsible for saving all data to flash memory
before it powers down the device. This is necessary to ensure data integrity.
6.3.4 Maximum ratings
Symbol Parameter Min Max Unit
Vin Permanent (DC) input voltage -33 33 V
Vin Transient peak input voltage 500 ms -50 50 V
Vin Transient peak input voltage 1 ms -200 200 V
