10.1
Channel selection
The wireless hand wheel HBG 800-DP offers a
choice of 21 channels. These channels are
separated into 2 frequency bands:
Channel 0 – 3:
869 MHz (for short antenna)
Channel 4 – 20:
433 MHz (for long antenna)
Upon delivery channel 0 is set.
To select a suitable channel please acknowledge
the following:
1
Are there further hand wheels or other units
working in the ISM band 433 MHz or 869 MHz
nearby?
2
If yes, with what frequencies do they work
exactly?
3
When using several wireless hand wheels the
used channels must be seperated. If possible
use different frequency bands, otherwise the
channel separation should be at least 3
channels (i.e. channel 4 + channel 7).
4
If machines are located side by side the channel
separation should be at least 6 channels (the
more the better) or use a different frequency
band! (i.e. channel 0 + 4)
Compare the frequencies of other units with the
frequency listing attached and choose only one
setting which is at least 300 kHz away from the
transmitting frequency of the adjoining units!
10.1.1 Field strength measurement
To search for a free channel a measuring routine is
integrated in the hand terminal:
o switch on all existing wireless units (measuring
sensor, crane controll systems, etc..)
o enter hand terminal set up (see 9.2)
o set menue point „Test-Nr“ to 5 (see 9.4)
o exit set up to run routine
Now the hand terminal scanns continuously all
channels until the routine is stopped with button X.
The eight best available channels show on the
display, the best on the upper left, the worst on the
lower right.
Alternatively the channels can be scanned manually
with test routine 7. The channels can be changed
with the b/-.
The maximum value can be reset with button X.
With the hand terminal walk up the operation range,
the maximum value should remain < 23! If this is not
the case, repeat the measurement using a different
channel. To do this, first switch off the hand terminal
with an emergency stop. After that start the setup
again and change the channel.
When selecting a channel please note the additional
points described under 10.1!
If you have found a suitable channel, inform the
access point of this channel accordingly:
o change to the new channel on the hand terminal
(9.3). While exiting the set up in the hand
terminal the new parameters will be transmitted
to the access point. The connection is interrupted
and must be started again afterwards.
10.2
Set transmitting power
Activate the test function 1 in the hand terminal.
Now the display shows the actual receiving field
strength and the minimum field strength.
With the hand terminal walk up the operating range,
is the minimum value < 30 then the transmitting
power must be increased. With a value of > 45 the
power should be decreased.
10.3
Set minimum level
The BG Institute demands a limitation in working
range. Therefore, a range value must be defined. If
the range value is violated, the vibration alarm sets
off and delays the forced shut off of the machine
(emergency stop).
Activate test routine 1 in the hand terminal and
determine the minimum value outside the operating
range.
The range value should be set to:
70 – measured value
Suggested range value: 35 - 45
11. Actions to avoid interruptions
1.
The hand terminal must be turned on before
taking it out of the charging station
2.
During the loading of work pieces and during
tasks where a hand wheel is not required,
always return the hand terminal to the charging
station
3.
Do not put larger objects into your way that
block your direct visible contact between the
hand terminal and the access point
4.
When the vibration alarm sets off, change your
position quickly. Most of the time a slight turn is
sufficient
5.
Avoid the use of mobile phones nearby.
Especially the D net can cause interruptions on
channel 0 through 3
6.
Clean the loading contacts on the charging
station and the hand terminal from time to time
