12. IMPORTANT OPERATING NOTES. TROUBLESHOOTING
!
For the trouble-free and optimum operation of the measuring set consisting of wireless sensors and AR40x base
unit (AR407/AR406), carefully read the operating instructions for these devices.
In case of normal, undisturbed transmission, the sensors activate cyclically to send the current measurement data
at the request of AR40x. The activation period is set in the AR40x recorder (for AR407 it is
Radio scan interval
parameter in
Communication options
, for AR406 it is
Recording/Scan interval
parameter in
Recording options
).
After switching on, AR40x waits for the measurement data and indicates it by message "
------
" in the field for
measurement values for a maximum time equal to scan interval. When the sensor is powered from USB port,
updating the measurements in AR40x base station is performed always every 5 seconds (and data recording in
AR406 still takes place according to parameter
Recording/Scan interval
, whereas in AR407 according to
parameter
Data recording interval
- set in
Recording settings
menu).
In case of communication problems
between the sensor and AR40x recorder (signalled by the sensor as
described in chapter 11 b), proceed as follows:
a.1)
check whether AR40x base recorder is turned on and operates on the appropriate radio channel
b.1)
reduce the distance or change the location of devices or antennas relative to each other (using
the antenna cable from accessories) to avoid obstacles such as walls, ceilings, furniture, etc.
c.1)
change (disturbed) radio channel in all system devices (in each separately) to another
d.1)
consider enabling retransmitter function (chapter 10.1, parameter 4.
RetrID
), where:
- the retransmitter requires external USB power supply (battery only as backup power)
- the retransmitter must also be registered in the system as a sensor (parameter 3.
ID
)
- the retransmitter must be within radio range of AR40x recorder (AR407/AR406)
- up to 3 retransmitters may be present in the system (each must have a different number)
- retransmitter updates measurements of AR40x base station every 5 seconds
In order to achieve the longest possible working time
without replacing the battery, remember to:
a.2)
set the highest possible value of scanning period
in AR40x recorder (recommended >10min)
b.2)
provide continuous and uninterrupted communication with AR40x (do not turn off the recorder)
c.2)
disable alarms when they are not needed (set lower and upper alarm set at the ends of the
measuring range, chapter 10.4)
If the estimated battery life (as described in note 1, chapter 4) is unsatisfactory,
consider using the USB power
adapter (from accessories), which may extend this time to approximately 8 years.
In addition, it is advised to not disconnect the device from the computer during communication via the USB
interface, which is indicated by the "
RX/TX"
and in ARSOFT-CFG-WZ1 software.
If the sensor is not responding, remove the battery briefly for a while and check its voltage level
(if it is less than 3.3V the battery needs to be replaced).
