3Product Features
The battery-operated measuring and display system HWD15 provides a hol-
low shaft (Ø 20 mm) and is directly attached to the spindle. The position is
detected by the integrated sensor and displayed on the LCD display.
Due to its housing with a stable rear wall and flange option including torque
support, the HWD15 is a robust measuring system. However, the mechanical
loads should be absorbed by the spindle. The hollow shaft rotates in a
maintenance-free plain bearing.
The extensive basic functions and parameters allow a wide range of applica-
tions. For example, the display can easily be adapted to the respective spindle
pitch (see 6.3). The device provides a common baby cell (good quality). So
the system operates within 12 months of continuous operation.
NOTE!
In the power-off mode the movements or adjustments of the magnetic sensor are not covered!
A referencing has to be performed after the start of operation (at a required mechanical posi-
tion, the indicator must be set to ZERO or to a defined reference value).
NOTE!
Independent of the setting in P07 (see 6.7), the basic resolution of the HWD15 is
0.01mm). All settings of the multiplication factor refer to this resolution!
3.1 Application Examples
Typical applications for the HWD15 are for example:
Manual and motorized adjustment units
Digital measurement of handwheels
Valve adjustments
Wrapping fixtures

7Disturbances, Maintenance, Cleaning
This chapter describes possible causes for disturbances and measures for their removal. In case of increased disturbances, please follow the
measures for fault clearance in chapter 7.1. In case of disturbances that cannot be eliminated by following the advice and the fault clear-
ance measures given here, please contact the manufacturer (see second page).
7.1 Fault Clearance
CAUTION!
The device, the connection line and the signal cable must not be installed next to sources of interference that emit
strong inductive or capacitive interference or strong electrostatic fields.
External perturbations can be avoided thorough suitable cable routing.
The screen of the signal output cable should only be connected to the following circuit on one side. The screens
should not be grounded on both sides. Signal cables always have to be routed separately from the load power line.
A safety distance of at least 0.5 m has to be kept from inductive and capacitive sources of interference such as con-
tactors, relays, motors, switching power supplies, clocked controllers etc.!
If interferences occur in spite of all the items stated above being observed, please proceed as follows:
1. Installation of RC-circuits via contactor coils of AC-contactors (e.g. 0.1 µF / 100 Ω)
2. Installation of recovery diodes via DC-inductors
3. Installation of RC-circuits via the different motor phases (in the terminal box of the motor)
4. Do not connect protective earth and ground
5. Connect a mains filter ahead of the external power pack
7.2 Re-start after Fault Clearance
After the fault clearance:
1. Reset the emergency stop mechanism if necessary
2. Reset the error report at the super-ordinate system if necessary.
3. Ensure that there are no persons in the danger area.
4. Follow the instructions from chapter 5.
WARNING! Danger of injury through non-conventional fault clearance!
Non-conventional fault clearance can lead to severe injuries and damage of property.
Therefore:
Any work to clear the faults may only be performed by sufficiently qualified staff
Arrange enough space before starting the works
Make sure that the mounting area is clean and tidy. Loose components and tools are sources of accidents.
If components need to be replaced:
Pay attention to a correct installation of the spare parts.
