1.11 BATTERY MANAGEMENT

For battery management, please read the safety instructions delivered with the instrument (printed and
on the CDROM)

1.11.1 Battery charge

When using a new battery, leave the battery in charge for about 10 hours in order to achieve full charge. Do not
use the instrument prior to 2-3 hours of charge. Usual charging time is about 6 hours when instrument is switched
off.

 Battery charge:

o Connect the instrument to the charger delivered with the instrument.
o Connect the charger to the mains. The instrument is automatically powered up. During the charge you

can continue using it. For a faster charge, it is recommended to switch the instrument off. A full charge
requires about 6 hours.

It is recommended to disconnect the charger from the mains when you are not using it.

1.11.2 Battery replacement

 Safety instructions:

o Do not use batteries other than type PIL1133 provided for HAWK and identified as 01dB

Metravib WILPA 2344A

o Do not open or disassemble the battery pack. The pack includes protections and an assembly

essential for the safety that should be changed in no case.

o The battery pack is interchangeable only for maintenance purposes. The operating lifetime of the pack

is sufficient for a full working day. The pack should not be changed periodically to artificially increase its
lifetime. The pack is not intended for this type of use, which would result in a dangerous mechanical
wear.

18

Brand of ACOEM

o Do not short-circuit the terminals of the battery connector. For safety reasons, the battery pack

includes an internal non-resettable fuse. A short-circuit makes it unusable.

o Respect voltage, current and temperature indicated on the label of the battery.
o Do not expose the battery to water or condensation.
o Do not place the battery in fire or near any other source of temperature (> 70°C). This can cause

overheating or a fire start. Such use may also lead to a loss of performance and a significant reduction
of the lifetime of the battery.

o Disconnect the battery and the charger immediately in the following situation:

 unusual odour
 abnormally high temperature

 Replacement instructions:

o Remove the battery:

 Unscrew the 2 screws of the battery trapdoor.

 Remove the connector by gently pulling the two cables. It should come off easily. In the case

of an abnormal resistance, do not force and contact our after-sales service.

 Remove the battery.

o When setting up the battery, be sure to not pinch or crush the cables.
o Check the orientation of the battery pack. The wire output must be placed beside the connector to

avoid crushing by the trapdoor.

o When inserting the battery, make sure not to hurt the pack. The insertion must be done without forcing

excessively. When in doubt, pull out the battery and check that nothing is blocking its insertion.

o Check the orientation of the connector. The coding should be facing up.

o To insert the connector, hold it with the cables.
o Check that trapdoor does not crush the cables by pushing them to the right hand side.

1.12 REMOTE DISPLAY & CONTROL FUNCTION

Procedure to take control of HAWK from a PC:

 Install Real VNC Viewer ® on the PC
 HAWK must be first networked by Ethernet (see § 1.8.3) or by Wi-Fi (see § 1.8.4) with the PC
 To work also with WLS Sensor, use the ‘Direct Wi-Fi connection PC- HAWK-WLS setting’ configuration.
 Run Real VNC Viewer ®
 Set the Input Server address: IP address of HAWK or its hostname (e.g., HAWK_10015) if there is a DNS.
 It is then possible to control HAWK from the PC.

Note: it is possible to protect this access with a password: see § 2.10

Access: Shortcuts panel > Settings

2.1 COLLECT

 Possibility to protect* the modification of some route data: sensor position pictogram, location or point picture,

barcode, rotation speed for measurement done by tachometer

 Possibility to protect* the functions ‘Delete’ and ‘Reset’ for routes not downloaded.
 Selection of data type displayed during acquisition: progress bar only, overall level, spectrum or time wave

* The protection is applied if you define a password on the last line of > Settings > About (See § 2.8)

2.2 MEASUREMENT

 Acquisition power supply permanent or not: If this option is set to YES, the acquisition components are

permanently supplied. If it is set to NO, its supply is activated only when a measurement is to be carried out,
but it requires a short waiting time before signal stabilisation. The advantage of permanent supply is the speed
to carry out numerous measurements. But the current consumption will be a little higher, and so the instrument
autonomy will be shorter.

 IEPE stabilisation time: increase pre-measurement delay for IEPE transducers with large stabilisation time.

Unit = second.
WARNING: when IEPE input type is selected, a constant current is powered up (current source: 4 mA – 23 DC).
It is important to check that the signal source is compatible.

 Pyrometer:

o External: temperature is measured on DC input
o Internal: temperature is measured with built-in pyrometer

 Pyrometer unit : °C / °F
 Wired channel number:

o Single: measurement is always done on channel 1 (connector A)
o Multi: measurements are done on channels 2 to 4 for triaxial compatible accelerometer configuration

(connector B) and on channels1 to 4 otherwise (connectors A and B)

 Accelerometer link:

o Wire: accelerometer is connected to connector A or B
o Wireless: use the WLS sensor (see § 1.7.2).

Note: Accelerometer link setting is not used for measurement synchronous with the tachometer input (e.g.,
Balancing module)

2.3 WIRELESS SENSOR

Instructions for the first connection are presented in § 1.7.2.

If the communication is bad or not possible, check following points:

 Check if the sensor is switched on and if the blue LED is continuously on (searching for connection) or

flashing (connected to an instrument)

 Check on HAWK if Wi-Fi is enabled in:

Shortcuts > Setting > > Wi-Fi = enabled

 Check if HAWK is set to work with a WLS sensor:

Shortcuts > Setting > > Accelerometer link = Wireless

 Check if the serial number of the sensor is that declared in HAWK

Shortcuts > Setting > Wireless sensor

 Check with a shorter distance and no obstacle between the sensor and the instrument.
 If the connection is OK and the communication is bad, it may be due to another Wi-Fi network using the

same channel. You can try to use another one:

Shortcuts > Setting > Wireless sensor:

o Change the channel number only in case of bad quality transmission
o Select in the list another channel
o Keep the sensor powered near the device
o Press "Save".
o It will take a few seconds for the sensor to restart on the new channel.

You can also use the test function, it returns:

 The status of the test (Successful or Failed)
 WLS firmware version
 WLS hardware version
 Sensitivity for each of the 3 channels.
