2.6 Product-specicsafetyinstructions
WARNING
Systempartsunderpressureandejectinghydraulicuid!
When working on hydraulic systems with stored energy (accumulator
or cylinder operating under gravity) hydraulic components may still
be under pressure even after the pressure supply was switched o.
During installation and demounting, pressure sensors or parts may
y around and cause personal injuries and/or damage to property.
There is moreover the risk of serious injury caused by a powerful,
ejecting hydraulic uid jet.
▶Before working on the hydraulic product ensure that the
hydraulic system is depressurized and the electrical control de-
energized.
▶Completely unload the pressure of machines and systems before
working on hydraulic products.
Improper mounting!
Improper mounting can cause the pressure sensor to loosen and
to fall down. Consequently, hydraulic uid may leak and lead to
personal injuries and/or damage to property.
▶Install the pressure sensor thoroughly according to the mounting
instructions by means of suitable mounting aids.
▶Adhere to the specied tightening torques.
Easilyinammablehydraulicuid!
In connection with re or other sources of heat, leaking hydraulic
uid mist, which results from defective or incompletely mounted
pressure sensorss and their connections, may lead to re or
explosions.
▶Do not use hydraulic components in areas with open re and only
at a sucient distance to sources of heat.

Safety instructions 13/48
RE 30277-02-B/07.2016, HEDE 10-3X, Bosch Rexroth AG
CAUTION
Exceedance of the maximum temperatures!
When the pressure sensor is operated outside the specied
temperatures, malfunction or failures, e.g. overheating, may occur
and thus pose a risk of injury.
▶Operate the pressure sensors only within the ambient and uid
temperatures provided for them.
• Before commissioning the pressure sensor, read this document and
make sure that the product is suitable for your application without
any restrictions.
• Check the compatibility of the product materials with the media to
be measured in all applications.
• Correct condition of the pressure sensor during operation can
only be guaranteed if it is only used for media, to which the wetted
materials are suciently resistant.
• The pressure sensor may only be operated within the specied
measuring range.
• The maximum pressure resistance specied must not be exceeded.
Even brief exceeding of the maximum pressure resistance can lead
to the destruction of the pressure sensor.
• Notes on pressure limits, product materials and materials in contact
with the media as well as further information can be found in the
technical data (see data sheet).

destroy it.
▶Never use pressure sensors as a handle or step. Do not place/put
any objects on top of it.
Pollutinghydraulicuid!
Leaking hydraulic uid leads to environmental pollution.
▶Remove any leakage immediately.
▶Dispose of the hydraulic uid in accordance with the national
regulations in your country.
Dirt and foreign particles in hydraulic components!
Penetrating dirt and foreign particles lead to wear and malfunctions.
Safe function of the hydraulic components is no longer ensured.

The units are vacuum-resistant.
5.2 Function
The pressure sensor displays the current system pressure. It
generates output signals according to the operating mode and the
parameter setting.
It moreover provides the process data via IO-Link.
The pressure sensor is designed for bidirectional communication. So,
the following options are provided:
• Remote display: Reading and displaying the current system pressure
• Remote parameter setting: Reading and changing current parameter
settings
• OI-Link parameter setting
OUT1 (pin 4) Switching signal for system pressure limit value
Communication via IO-Link
OUT2 (pin 2) Analog signal of the system pressure
5.2.1 Switching function
OUT1 changes its switching state if it is above or below the set
switching limits (SP1, rP1). The following switching functions can be
selected:
• Hysteresis function / normally open: [ou1 = [Hno] (see Fig. 1).
• Hysteresis function / normally closed: [ou1] = [Hnc] (see Fig. 1).
• First the set point (SP1) is to be determined, then the reset point
(rP1).
The hysteresis thus dened remains, even if SP1 is changed again.
• Window function / normally open: [ou1] = [Fno] (see Fig. 2).
• Window function / normally closed: [ou1] = [Fnc] (see Fig. 2).
• The width of the window can be set by means of the dierence
between FH1 and FL1. FH1 = upper value, FL1 = lower value.

5.2.3 IO-Link
General information
The pressure sensor is provided with an IO-Link communication
interface, which requires an IO-Link-capable module (IO-Link master)
for operation.
The IO-Link interface enables direct access to the process and
diagnostic data and provides the possibility of setting parameters of
the pressure sensor during operation.
In addition, communication is possible via a point-to-point connection
with a USB adapter cable.
You can nd the IODDs necessary for the conguration of the device,
detailed information about process data structure, diagnostic
information and parameter addresses as well as the required
information on the necessary IO-Link hardware and software at
