1.3 Intended use
The HS-517 vibration trip display is designed to indicate measurement
values on a build in LED display and is optionally equipped with
a Relay (with PNP open collector output). ). It is designed to be used
with Vibration Transmitters HS-420I and HS-422I Series with 4...20mA /
2-wire analogue output. The HS-517 may be used with all transmitters if the
following requirements are met:
•output signal of the transmitter: 4 … 20 mA / 2-wire
•suitable electrical connection (according to data sheet)
The digital vibration trip display HS-517 has to be mounted between
the connector and transmitter and is ready for immediate operation. No
additional supply is required, the display is supplied by the 4 … 20 mA circuit. A
preferred application is on-site process monitoring in combination with the HS-420I
or HS-422I Series.
Programming is performed via two buttons on the front side. The following
parameters can be set: scaling, decimal point, damping, switch point, and delay.
Moreover, a min./max. value memory is available. The settings will be retained
even in case of a power failure. Incidences of range exceedance in both directions
can be displayed as messages. The integrated diagnostic system constantly
monitors all functions of the display. The housing can be turned by 300° in an
infinitely variable manner, the display by 330°.
This operating manual applies to devices with explosion protection approval and is
intended for the use in IS-areas. A device has an explosion-protection approval if this
was specified in the purchase order and confirmed in our order acknowledgement. In
addition, the manufacturing label includes a sign.
The user must check whether the device is suited for the selected use. In case

of the overall system (entire circuitry).
NOTE - Make sure that an equipotential bonding is in place for the entire course
of the line, both inside and outside the intrinsic area.
NOTE - The external circuit must prevent an external power-in-flow to the
contacts. Suitable signal separating devices which fulfil this demand have to be
used.
NOTE - If there is increased risk of damage to the device by lightning strike or
overvoltage, increased lightning protection must additionally be provided!
NOTE - Do not remove the packaging of the device until shortly before the

electrostatic charging
DANGER
Danger of death from explosion
-Explosion hazard due to spark formation from
electrostatic charging of plastic components.
-If devices are equipped with a cable outlet, the
connection cable routing must be fixed.
-Do not clean the device and, if applicable, the
connection cable, in a dry state! Use a moist cloth, for
example.
Overvoltage protection
If the device is used as electrical equipment of category 1 G, a suitable
overvoltage protection device must be connected in series (attend the valid
regulations for operating safety as well as EN60079-14).
Schematic circuit design
The operation of an intrinsically safe device in intrinsic safe areas requires special
care when selecting the necessary Zener barrier or transmitter repeater devices to
be able to use the device’s characteristics to the full extent. The following diagram
shows a typical arrangement of power supply, Zener barrier and plug-on display.
HS-517 User Manual
Fig. 3 : circuit diagram
- 11-

QM039 Issue 1
NOTE - Observe item (17) of the type-examination certificate which specifies
special conditions for intrinsically safe operation.
Exemplary circuit description
The supply voltage of e. g. 24 VDC provided by the power supply is led across the
Zener barrier. The Zener barrier contains series resistances and Zener diodes as
protective components. Subsequently, the operating voltage is applied to the
device and, depending on the pressure, a particular signal current will flow.
Selection criteria for Zener barriers and galvanic power supply
The minimum supply voltage V
S min of the device must not fall short.
When using a galvanically insulated amplifier with a linear bonding, please attend
that the terminal voltage of the device will decrease like it does with a Zener
barrier. Furthermore, account must be taken of the fact that a certain voltage drop
will also occur on an optionally used signal isolation amplifier, whereby the
operating voltage of the device will decrease additionally.
Test criteria for the selection of the Zener barrier
In order not to fall below VS min, it is important to verify which minimum supply
voltage is available at full level control of the device.
The technical data of the barrier will usually provide the information needed for
the selection of the Zener barrier. However, the value can also be calculated. If a
minimum supply voltage of e.g. 16 V is assumed, a certain voltage drop on the
series resistor of the Zener barrier follows in accordance with Ohm’s law. If the
contact is additionally activated on a device with PNP switch output, the additional
current flowing from the contact to the load resistor will also flow through the
Zener barrier or from the output of a galvanic power supply. The higher the load
current, the lower the available minimum operating voltage. In the circuit shown,
the maximum current can be calculated from the maximum voltage difference (Vab
barrier max) between input and output of the Zener barrier divided by the series
resistance of the Zener barrier. The maximum signal current must be subtracted
from this value. If the available residual current is smaller than the current
required at the contact, either a different barrier or a higher supply voltage before
the barrier should be chosen.
NOTE - When selecting the power supply, the maximum operating conditions
according to the EC type-examination certificate must be observed. When
assessing the power supply, please refer to their current data sheets to ensure
that the entire inter-connection of intrinsically safe components will remain
intrinsically safe.

QM039 Issue 1
HS-517 User Manual
Calculation example for the selection of the Zener barrier
The nominal voltage of the power supply in front of the Zener barrier is 24 VDC ± 2%.
This results in:
- greatest supply voltage: VSup max = 24 V * 1.02 = 24.48 V
- smallest supply voltage: VSup min = 24 V * 0.98 = 23.52 V
First, the minimum supply voltage of the combination of plug-on display and transmitter
must be determined. This results from the minimum supply voltage of the transmitter
plus the voltage drop of the plug-on display which is nominally 6 V. For example, UB
transmitter min = 10 V results in a minimum supply voltage
VB min = 16 V.
The series resistor of the Zener barrier is specified with 295 Ω. The maximum voltage
drop at the Zener barrier may reach the following value:
Vab barrier max = 23.52 V – 16 V = 7.52 V
In order for this condition to be adhered to, the maximum current must not exceed the
following value:
Imax = 7.52 V : 295 Ω = 25.49 mA
The maximum current of the combination of plug-on display and transmitter is made up
of the sum of signal current and switching current. There are two approaches:
1. The measuring range is to be utilized in the range of
0 … 100 %. A maximum signal current of 20 mA is generated thereby. Based on
the facts above, the available residual current through the switch output is
calculated as follows:
IResid 1 = 25.49 mA – 20 mA = 5.49 mA
2. With an analogue output of 4 ... 20 mA, the measuring range is to be utilized only
in a specific range, e.g.
0 … 70 %. This results in a maximum signal current:
ISignal max = ∆i * 0.7 + iOffset = 16 mA * 0.7 + 4 mA = 15.2 mA (with ∆i = 20 mA – 4
mA and iOffset = 4 mA)
Here, the available residual current through the switch output is:
IResid 2 = 25.49 mA – 15.2 mA = 10.29 mA
Condition: IResid ≥ ISwitch output
The switching current (current through the switch output) must not exceed the
determined residual current since this will impair the functionality of the device.
NOTE - The switching current must be determined separately by the user as it
depends on the particular case of application. The switching current can be calculated
or measured at the switch output.
NOTE - Please note that no line resistances have been listed in this calculation.
These lead additionally to a voltage drop that must be taken into account.

The menu system is a closed system allowing you to scroll both forward and backward
through the individual set-up menus to navigate to the desired setting item. All settings
are permanently stored in an EEPROM and therefore available again even after
disconnecting from the supply voltage. The structure of the menu system is the same
for all types of devices, regardless of the number of contacts. However, they only differ
by the number of menus. Following figure and the menu list shows all possible menus.
Please follow the manual meticulously and remember that changes of the adjustable
parameters (switch-on point, switch-off point, etc.) become only effective after pushing
both buttons simultaneously and leaving the menu item.
