4.3 Automatic Detection of the Sensor Type
The VBA-2E-G11-I/U/PT100-* analog input module automatically detects which sensor type is
connected. The types of sensors that can be connected are: 0 V ... 10 V measurement
sensors, 0/4 mA ... 20 mA-measurement sensors, or Pt100 temperature sensors. The sensor
type is automatically detected once switched on. Once the module has detected the sensor
type, the corresponding module configuration is activated.
All input LEDs are illuminated during the first few seconds after switching on. During this time,
the module evaluates the connected sensor type on the basis of various measured values. The
signal values that ensure unambiguous detection of the type of sensor connected are:
■ Voltage: 1 V ... 11.5 V
■ Current: 1 mA ... 23 mA
■ Pt100: -219 °C ... 884 °C
If the module cannot clearly establish which sensor type is connected, the last detected sensor
type is provisionally activated. For example, the module may not detect which sensor type is
connected if the signal values are not within the specified thresholds or if two different sensor
types are simultaneously applied to one channel.
A specific sensor type is finally activated when the signal values measured are within the
specified thresholds.
Note!
Switching Off the Second Channel
Figure 4.4 Input PT2 bridge
Two bridges are plugged in at the PT100 input PT2 by default; these bridges are designed to
switch off channel 2. Remove the bridges to use channels 1 and 2.
The bridges must be plugged in and disconnected only when the module is de-energized!

Note!
The Pt100 Input Is an Exception:
The Pt100 sensor type is only activated if a Pt100 temperature sensor is connected to the
PT100 inputs before switching on. The Pt100 sensor type cannot be activated during operation
or activated provisionally.
Note!
If you connect two different sensor types to one channel simultaneously, fault-free operation is
not guaranteed. The module will not be damaged by this.

Product Description
4.4 Pt100 temperature sensor
Pt100 temperature sensors are platinum resistance thermometers complying with standard
IEC 751 / DIN EN 60751. In this standard, various values of the temperature sensor are
defined. The nominal resistance of the Pt100 is 100 , measured at 0 °C. Furthermore, as well
as other values, the mean temperature coefficient of 0°C to 100 °C is also defined. The mean
temperature coefficient defines the mean change in resistance relative to the nominal
resistance. The analog module calculates the corresponding temperature based on the
measured resistance of the temperature sensor.

Commissioning
6 Commissioning
6.1 Assigning an Address to the Module
To operate the VBA-2E-G11-I/U/PT100-* in an AS-Interface network, you must assign a
suitable address to the AS-Interface slave. The AS-Interface VBP-HH1-V3.0 handheld device
by Pepperl+Fuchs or an AS-Interface master can be used to assign addresses.
The VBA-2E-G11-I/U/PT100-* module is a standard slave as defined by specification 2.1.
These modules can be assigned addresses 1 to 31. The default address on delivery is 0.
6.2 Slave Profile
The VBA-2E-G11-I/U/PT100-* has the profile
S-7.3.D
The data value is transmitted as defined by AS-Interface profile 7.3.
6.3 Parameterization
The following parameters can be set for the VBA-2E-G11-I/U/PT100-*. Program the
parameters using an AS-Interface master, with the VAZ-SW-ACT32 AS-i Control Tool from
Pepperl+Fuchs or with the VBP-HH1-V3.0 handheld device.
Parameter P0: 50/60 Hz Filter
Default value P0=1, active
With parameter P0, you activate the filter for 50/60 Hz power frequencies. With an activated
filter, power frequency interference is suppressed. In this case, the conversion time is extended
(see chapter 9.2).
Parameter P1: Second Channel
Default value P1=1, active
Parameter P1 is used to switch the second measuring channel on or off. If the second channel
is switched off, this can considerably reduce the conversion time in the module. (see chapter
9.2)
Alternatively, it is possible to control the second channel via the bridges on input PT2. (see
chapter 4.2)
I/O = 7
ID = 3
ID1 = F (programmable)
ID2 = D
Note!
The bridges on input PT2 override parameter P1.

Parameter P2: Peripheral Fault
Default value P2=1, active
Parameter P2 is used to switch notification of a peripheral fault in the event of a measuring
overrange on or off (see chapter 9). If notifications are activated, the AS-i/FAULT LED flashes in
the event of a peripheral fault, and a notification is sent to the master.
A peripheral fault is always reported if:
■ The power supply is overloaded.
■ The external power supply is not available when the INT/EXT switch = EXT.
Parameter P3: Current Input 0 mA ... 20 mA
Default value P3=1, not active
Parameter P3=0 is used to set both input channels to current mode. Wire break detection is
simultaneously deactivated. (see chapter 9.1)

Troubleshooting
7 Troubleshooting
7.1 Causes and Elimination of Peripheral Faults
A peripheral fault (P fault) is indicated by the color and flashing of the AS-i/FAULT LED. There
are various causes of and solutions for correcting peripheral faults.
If none of these potential solutions correct the peripheral fault, please contact Pepperl+Fuchs.
7.2 Cause and elimination of a channel fault
If channel 2 is not transferred and the LED at the connection of the relevant input of channel 2 is
not illuminated, channel 2 is not activated.
Cause Solution
Sensor supply overload ■ Check sensor supply for short circuit
Measured values outside the
measurement range
■ Check the connected measurement sensor/Pt100
temperature sensor for wire break/short circuit
Auxiliary power too low (switch set to
EXT)
■ Check the auxiliary power source
Cause Solution
Jumper plugged at PT100-input PT2 ■ Remove jumper (see chapter 4.2)
Parameter P1=0 ■ Change parameter P1 (see chapter 6.3)
