5.3 Calibrating the position system
To calibrate the position system (adapt the internal device processing to mirror actual
conditions at the place of installation) it is necessary to determine the system limits, calibration point, calibration factor and unit.
• The system limits define the max. possible working range. An error will be
triggered if values exceed or fall below the defined range.
PLEASE NOTE!
To avoid system limit errors ensure sufficient clearance between the system limits and the switching points.
• The operating range must not exceed 32768 rotations of the device shaft.
• The preset position value is a defined position point (calibration point).
• The calibration factor is the adaption factor between system units and device units.
It is assumed that this ratio is constant.
If unknown, it is possible to determine the calibration factor via the menu item
“Options Determine calibration factor” (see Chap.5.3.2).
In this instance it is possible to determine the calibration factor with the aid of 2
calibration points, the interval between which should be as great as possible but must
not exceed the system limits.

5.3.1 Calibration
1. Select the desired unit via the pulldown menu
2. Enter the values for the system limits and the calibration point (preset).
The following constraint applies:
Lower system limit < calibration point < upper system limit
3. Enter calibration factor. For information on calculating the calibration factor see Chap.
5.3.3.
4. To save values to the USC 42 click , see Chap. 5.4.
5. Move to the calibration point (preset), shut down the drive and click the button.
Thecurrent position is saved as the calibration point.
6. To complete the calibration procedure click button. The USC 42 is
calibrated and can now be configured.
5.3.2 Determining the calibration factor with two calibration points
1. Enter calibration point 1 and calibration point 2.
The following constraints apply:
• Lower system limit < calibration point 1
• Calibration point 1 < calibration point 2
• Calibration point 2 < upper system limit
2. Move to calibration point 1 and shut down the drive,
click the button . The current position is saved as calibration point 1.
3. Move to calibration point 2 and shut down the drive, click the button . The
current position is saved as calibration point 2.
4. The calibration factor has been calculated, saved to the clipboard and can now be inserted in the appropriate dialog box.
5.3.3 Determining the calibration factor by calculation
Calibration factor = (device shaft rotations) x 8192 / Actual path in number of plant units
Example:
34.5 m travel corresponds to 125.7 rotations of the device shaft.
Calibration factor = 125.7 x 8192 / 34.5 = 29847.37

6 Functions
6.1 SCU C module
The SCU C module (Safety-Control Unit) is the central control unit of the USC 42.
To assign the module a user-defined designation click the symbol . That makes it easy
to allocate the device on site (for example, “drive 2"). The length of the designation is
limited to 12 characters.
On the tabbed page “Options” it is possible to make the following settings.
6.1.1 Digital inputs
The inputs must be activated prior to use. Both inputs are 2-channel types (Cat. 3) and
active low; in other words, when quiescent the inputs must be high. A falling edge at
both channels initiates the process. Valid rising edges initiate the process. The duration
of the low level signal T1 can be configured - and is the same for both inputs.
• Reset:
A reset procedure re-initializes the whole
USC 42 system; it also resets errors in
line with parameter assignments.
• Preset:
A preset procedure sets the current
position to the preset position configured
in the device. A low level signal at the
status output (approx. 1s) acknowledges
a valid preset procedure.
The time T1 can be set between 20
ms … 200 ms or 200 ms … 2000 ms
(factory setting: 200 ms … 2000 ms).
To alter the behaviour of the Reset and Preset
inputs from Low active to High active select the
“Preset/Reset 1 active” check box.
PLEASE NOTE!
If test pulses (Fig. 6-3) are used on the inputs they must not exceed max. ¼
of the min. duration of T1 (5ms or rather 50 ms).
CAUTION!
It is only allowed to set a preset “on the fly” if a risk analysis determines the
application is suitable to allow this function.
CAUTION!
A preset does not influence the position value of the bus module (SPB,
SPN). It is only possible to alter this position value via the bus interface.

6.1.2 Digital outputs
There are 2 digital outputs: Status and error output.
Both outputs are 2 channel (Cat. 3) types. Both channels
of an error output must have the same status
(open/closed) and both must be monitored by the application. An error will be flagged if the channels are not the
same.
• Error output:
When the status is error-free both channels of the error output are high and transmit
test pulses (factory setting see Fig. 6-3). The USC 42 monitors the output to ensure it
is functioning properly.
CAUTION!
If the error output is utilized to detect a device error it must be subject
to a safety-related evaluation (see document “USC 42_Manual-en_R..”
Chapter: Application examples).
The receiver must suppress the test pulses to avoid unwanted switching operations.
- The following settings are available to set the duration of the test pulses:
100 ms, 10 ms, 1 ms, off (factory setting: 1 ms).
- For the quotient ‘test pulse interval / test pulse duration’ (T/ti) it is possible to select
10, 100, 1000 (factory setting: 1000).
- The test pulse offset (test pulse offset between channels) tc = 2* ti cannot be set.
For non-safety relevant applications it is possible to deactivate the test pulses. An
error is indicated by a low-level signal at the error output, which can only be reset via
the configuration software "US42Pro" (factory setting). It is possible to set the error
performance via the software so that an error will also be reset by interrupting the
supply voltage (> 2s) or by initiating a reset at the reset input).
The reset always initiates a system reboot including a complete system test. If an
error is determined again, the device remains in an error condition. Error logs are
saved in the error memory.
CAUTION!
The "fault reset via the reset input or power supply interruption" option
may be used only if a risk analysis has shown that the application is
suitable.
• Status output:
The status output indicates the operating status in conjunction with the error output of
the USC 42 (see separate operating and assembly instructions. Chapter: Operating
conditions and indicators). The status output does not issue any test pulses.

6.1.3 Current output (non safety related)
The current output can be set to speed or position dependent on the menu and must be
activated before use.
6.1.3.1 Configuring the position-dependent current output
To configure the position-dependent current output it is necessary to enter 2 position values, which must be within the
system limits.
The smaller position value is assigned current I
min
= 4 mA and
the larger position value I
max
= 20 mA.
The following restriction applies:
• Pos1 < Pos2
If the current position is outside of the defined position range,
the current output is switched to high impedance (I = 0 mA).
(Factory setting).
Alternatively, it is possible to select a setting to take effect in
the event the value falls below or exceeds the determined position range 4 mA or 20 mA.
6.1.3.2 Configuring the speed-dependent current output
To configure the speed-dependent current output it is necessary to enter the speed
n20 mA
. When at a standstill a current of
4 mA flows.
The following constraint applies:
• n
20 mA
< (approved mechanical speed -10%)
If the speed exceeds the speed range (n
current
> n
20 mA
), the current output is switched to high resistance
(I = 0 mA) – (factory setting).
Alternatively, it is possible to select a setting to take effect in
the event the value exceeds the determined position range
20 mA
.
6.1.4 Configuring the incremental output (non safety-related)
The incremental output is optional. To configure the incremental output it is possible to select a pulse rate of 1024 or
4096
(factory setting: 4096).

6.2 SRC C module
The SRC C module is a position switch module and contains 3 or 6 position switches.
The position switch opens or closes depending on the position value. The position
switches are 2 channel types (2 NO contacts, Cat. 3).It is possible to implement a cam
with a single switch; in other words, a switch-on and switch-off position and the associated hysteresis switching points.
The position values to be entered must be within system limits. It is possible to assign
each position switch an application-specific designation (max. 12 characters). Switching
modules with 6 position switches are configured on 2 monitor display screens. The parameters are entered in the table as shown opposite.
The values are highlighted yellow if there is a risk that
the minimum changeover interval (2 ms) between 2
switching conditions could be undershot. If such an
event occurs the user must check the time interval in
his application.
• P1: Hysteresis switching point of P2.
• P3: Hysteresis switching point of P4.
The following condition applies:
P1 < P2 < P3 < P4
• Inverted: The switch operates inverted (see switch
S3).
• Error switch: Switch opens only in the event an
error occurs (see switch S2).
• Open if an error occurs:
Switch operates as configured, but opens if an error
occurs.
The switching points are depicted in their correct
position in the graphic opposite.
A marker indicates the current position.

6.3 SGS C module
The SGS C-module is a speed switch module. The speed switch opens or closes depending on the speed. A speed switch module has 3 or 6 speed switches. Switching
modules with 6 speed switches are configured on 2 configuration screens. Fundamentally, all switching speed inputs must be within the device-specific switching range
0.5-2520 rpm.
The speed-dependent functions are depicted in a graphic in the top part of the
screen.
The input fields for entering speed switching points are displayed in the lower part of
the screen in table form. One line is allocated to each respective switch (S1-S3 or
S1R to S3L).
The columns are assigned to the respective speed switching points P1 to P4, and
the switching delay P4 (max. 300 ms).
The following condition applies:
P1 < 0.9 x P2 < 0.9 x P3 < 0.9 x P4
or P1 = P2 = 0
The switching points are depicted in the graphic opposite. A marker indicates the
current speed

Only those lines and columns are displayed that are relevant to the respective function
selected by checking the appropriate boxes.
An input value "0" in the fields P1 … P4 deactivates the corresponding switch.
An input value "0" in the fields P1 … P2 deactivates underspeed detection
(see Chapters: 6.3.1, 6.3.2).
CAUTION!
When switching delay is activated the actual cut-off speed can be higher than the
set cut-off speed!
Observe also the information on determining switching accuracy described in the
Operating and Assembly Instructions " USC 42_Manual"!

Fig. 6-10
Click "Write to device" to finish configuring the module.
6.3.1 Underspeed
Underspeed is detected. The respective switch closes first when speed P2 is exceeded;
the switch is opened again when the speed falls below the P1 threshold. The input columns for "P1" and "P2" are depicted if underspeed detection is activated.
6.3.2 Rotation direction dependent
The switching speeds S1R … S3R apply to clockwise direction of rotation. The speeds
S1L … S3L apply to anticlockwise direction of rotation.
The input lines for S1R-S3R as well as S1L-S3L are depicted if 'rotation direction dependent switching' is activated.
If no 'rotation direction dependent switching' is activated the switches S1 ... S3 are not
labelled with a direction of rotation indicator R or L; the entered switching speeds apply
independent of the direction of rotation.
PLEASE NOTE!
If 'rotation direction dependent switching and underspeed are selected, the underspeed function must be equal for both directions of rotation. Either active or inactive.

6.3.3 Switching delay
The adjustable switching delay makes it possible to prevent the overspeed switch
switching if the limit speed is exceeded only briefly. That can be appropriate during load
shedding, for example. If the speed P4 is exceeded the switches S1, S2 and S3 close,
and open only after the delay time set in the "Delay" field has elapsed. It is possible to
set the time between 0 and 300 ms. The cut-off function is not triggered if the speed
again falls below the P4 figure within the set delay time.
PLEASE NOTE!
The delay time applies only to the cut-off function when the speed P4 is exceeded.
All other switching operations are triggered immediately.

6.5 Error handling
Numerous diagnostic measures check the functions and operating conditions of the
USC 42 at power up and during runtime.
In the event of a deviation, the error state (safe
state) is initiated and the error is stored in the error
memory.
An error distinction is made between "internal errors" and "external errors".
External errors are caused by external influences, e.g. exceeding the max.
permissible speed or exceeding the max. permissible temperature. The errors are
explained in the parameterization software with a brief description of the error, as
described in Chap. 6.5.1 displayed.
External errors are reset by a reset (reset input or reset button in the US42Pro
software) or by interrupting the supply voltage (> 2s).
Internal errors are e.g. triggered by deviations of the device-internal program
sequence. The errors are displayed in the parameterization software with error
number and the designation "internal error". An analysis of the cause of the error is
only possible with expert knowledge. To do this, the user must send the contents of
the fault memory to the manufacturer (see chapter 4.1.19).
Internal errors can only be reset via the reset
button in the US42OPro software (factory
setting).
Resetting the internal error can be set with the US42Pro software to match that of
the external error.
Resetting the error triggers a system restart with a complete system check. If an
error is detected again, the USC 42 remains in fault state.
The error state can be assigned to a switching output with the parameterization
software.
