2 Safety instructions
To ensure safe operation, carefully observe all instructions in this manual.
The correct and safe use of this device requires that operating and service personnel both
understand and comply with general safety guidelines and observe the special safety
comments listed in this manual. Where necessary, safety-sensitive points on the device
are marked.
DANGER
Because the device is electrical equipment, commissioning and service must be performed
only by trained and authorized personnel. Maintenance must be carried out only by
trained, specialized, and experienced personnel.
2.1 Using the device
Install and use the device as specified in this document.
If the device is used in a manner not specified by the manufacturer, the functions and
protection provided by the device may be impaired.
2.2 Owner's responsibility
If there is a reason to suspect that hazard-free operation, and thus, adequate machine
protection is no longer possible, take the device out of operation and safeguard it from
unintentional operation. This is the case:
• if the device shows visible damage.
• if the device no longer works.
• after any kind of overload that has exceeded the permissible limits (such as those
detailed in chapter "Technical data," section "Environmental conditions").
DANGER
If device tests have to be completed during operation or if the device has to be replaced or
decommissioned, it will impair the machine protection and may cause the machine to
shut down. Make sure to deactivate machine protection before starting such work, and
reactivate it after work has been completed.
2.3 Radio interference
The device is carefully shielded and tested to be technically immune to radio interference
and complies with current standards. However, if you operate this device together with
other peripheral devices that are not properly shielded against radio interference,
disturbances and radio interferences may occur.

2.4 ESD safety
DANGER
Internal components can be damaged or destroyed due to electrostatic discharge (ESD)
during the handling of the device.
Take suitable precautions before handling the device to prevent electrostatic discharges
through the sensor electronics. Such measures might include, for example, wearing an
ESD bracelet. Transport and storage of electronic components may only be made in ESDsafe packaging.
Handle the device with particular care during dry meteorological conditions with relative
humidity below 30% as electrostatic discharges can appear more frequently.

3 Installing the VI Tach CHARM
hardware
3.1 About the VI Tach CHARM hardware
The VI Tach CHARM is a single channel measuring module for the connection of:
• Externally powered eddy current sensor outputs
• Passive magnetic sensors
• Hall-effect sensors
The CHARM is equipped with an internal power supply to directly supply Hall-effect
sensors. The CHARM calculates speeds and generates key-signals from the input signal.
The generated key-signal is within a frequency range of up to 2000 Hz. Parameters for the
input signal processing are software configurable. The key-signal is available within the
AMS Asset Monitor, in which the CHARM is installed, for other CHARMs that require a key
signal for signal processing.
The VI Tach CHARM can be installed in the AMS Asset Monitor. The standard CHARM
Terminal Block KL4502X1-BA1 is required for the installation.
The maximum permissible input voltage of the VI Tach CHARM is 30.3 V AC. The
maximum input voltage of 30.3 V AC is also the maximum permissible input voltage when
using the VI Tach CHARM in explosion-hazardous areas.

3.2 Install the VI Tach CHARM
The recommended procedure depends on the system in which the VI Tach CHARM is to be
installed. See AMS Asset Monitor manual for the recommended procedure. The described
procedure is a recommendation and can be changed to the needs of your project.
CAUTION
Any work on the system may impair asset health monitoring and machine protection.
Prerequisites
• A prepared slot with an already installed CHARM Terminal Block (KL4502X1-BA1) in a
compatible system such as an AMS Asset Monitor
• A suitable flat-tip screwdriver for the terminal screws of the CHARM Terminal Block
• Ensure that the electrical requirements of the sensor to be connected comply with the
electrical input requirements of the VI Tach CHARM

Installation Guide Installing the VI Tach CHARM hardware
MHM-97930-PBF June 2022
CAUTION
Do not swap the polarity of the CHARM's voltage supply. Because of the internal
connection of the signal input GND and the power supply GND, it is not possible to use the
+24 V power supply as a -24 V power supply.
Select from Step 3 to Step 5 the step that is in accordance to the used sensor.
Procedure
1. Ensure that the latch of the CHARM Terminal Block is in the open position. If the
latch is in the closed position, move it outwards to open it.
2. Gently push the VI Tach CHARM straight into the already installed CHARM Terminal
Block. The CHARM latch locks with an audible click in the closed position.
Note
The CHARM is hot-swappable. It is not necessary to switch off the power supply of
the system before installing or removing the CHARM.
Figure 3-2: CHARM installation
A. Standard CHARM Terminal Block (KL4502X1-BA1)
B. VI Tach CHARM
The CHARM Terminal Block contains keying posts that are automatically set and
locked to the unique position of the installed CAHRM. The keys prevent the
insertion of an incorrect CHARM during maintenance activities.
To reset the keying mechanism, remove the CHARM Terminal Block from the
CHARM Baseplate, flip the terminal block 180°, and use your fingers to push the two
keying posts completely in so they are sub flush to the bottom face of the terminal
block. Sub flush is the neutral position. You will hear a click when the posts are in
the neutral position. When the posts are in the neutral position, the terminal block
can receive a different CHARM type.

DANGER
Do not try to install the VI Tach CHARM into a CHARM Terminal Block with keying
posts set for another CHARM type. This might damage Terminal Block and CHARM.
3. Connect a signal of an eddy current sensor to the CHARM Terminal Block. The
supplying of an eddy current converter is not supported by the CHARM.

Event Proposed solutions
CHARM is healthy but
configuration is incomplete
CHARM has a
communication fault
Signal wiring fault, but
CHARM passed all self tests
CHARM failed to get address
assignment
Complete the commissioning of the VI Tach CHARM. See
operating manual of the system where the CHARM is
installed.
a. Check the system where the CHARM is installed for
configuration issues.
b. Check the hardware. Are there any contact problems
between the baseplate and the CHARM Terminal block
or between the CHARM Terminal Block and the
CHARM?
c. Replace the CHARM and the CHARM Terminal Block to
exclude hardware faults.
d. In case of an hardware fault, replace the defective
component.
a. Check the sensor wiring for cable break, loosened
contacts, and wiring faults.
b. Measure the sensor signal. Does the sensor signal meet
the limits of Figure 5-1, Figure 5-2, or Figure 5-3
(depending on the connected sensor)?
a. Check the system where the CHARM is installed for
configuration issues.
b. Check the hardware. Are there any contact problems
between the baseplate and the CHARM Terminal block
or between the CHARM Terminal Block and the
CHARM?
c. Check the Address Plug of the system where the
CHARM is installed.
d. Replace the CHARM, the CHARM Terminal Block, the
Address Plug, and the CHARM Address Terminal Block
to exclude hardware faults.
e. In case of an hardware fault, replace the defective
component.

4. Continue troubleshooting with the assistance of the technical support if the CHARM
is still not working as expected.
5.3 Repair
Repair of a defective VI Tach CHARM is not possible. In case of defects, the VI Tach CHARM
must be replaced.
5.4 Replace a VI Tach CHARM
It is not possible to repair a VI Tach CHARM. In case of defects, the CHARM must be
replaced. Follow the steps listed below if a CHARM needs to be replaced.
CAUTION
Any work on the system may impair asset health monitoring and machine protection.
Note
The CHARM is hot-swappable. It is not necessary to switch off the power supply of the
system before installing or removing the CHARM.

The configuration of the CHARM is stored in the system. So it is not necessary to create a
backup of the configuration before replacing the CHARM.
Procedure
1. Remove the CHARM from the CHARM Terminal Block. See Remove the CHARM.
2. Install the new CHARM. See Install the VI Tach CHARM.
The CHARM is automatically detected by the system.
3. Ensure that the CHARM has been correctly detected by the system and is working
fault free.
Check the status LED on the front of the CHARM and the status indication on the
system software.
