(2) Default: 600 r.p.m.
Higher rotation speeds to 600 r.p.m. can be maintained for short periods of time.
The value of the max speed affects the battery life.
3. Assembly
1. Drill a Ø 6x10 mm hole in the body of the machine with a 22 mm centre
distance from the shaft to fit the
rear referring pin.
2. Fit the indicator onto the shaft and
make sure that the referring pin fits
into the hole.
3. Clamp the bushing to the shaft
by tightening the grub screw with
hexagon socket and cup end,
according to UNI 5929-85.
4. Turning on the system
After you have read and understood the section “Safety Instructions”, proceed
by switching on the indicator.
To turn the indicator on hold while pressing the key .
The display will light up and the indicator will be ready to be used.
4.1 Turning off the system (only for storage)
To turn the system off enter the programming mode, select the
rESEt
parameter then press the key . At this point, press the button for 5
seconds; the display will turn off and the indicator will go into low power mode
of the battery.

7. Operating mode
7.1 Absolute / incremental measuring mode selection
Press the key to select the absolute or incremental measuring mode.
The measuring mode selected is shown on the display by the symbols:
-
ABS : absolute measuring mode
-
REL : incremental measuring mode
It is possible to change the key function by setting the
parameter
__0__
The available options are:
-
ArCLr (default): passing from ABS to REL the counter is set to zero.
-
Ar : passing from ABS to REL the counter is not set to zero. In this case,
the counter is set to zero by pressing + .
-
OFF : the key is disabled and does not allow changing the selected
measuring mode.
To program the parameters listed above, see paragraph 8.2.
7.2 Unit of measure selection
Press the key to select the unit of measure needed. The options available are
millimeters, inches and degrees.
The measuring mode selected is shown on the display by the symbols:
-
mm : millimeters
-
INCH : inches
-
D : degrees
It is possible to change the key function by setting the
parameter
____0
The available options are:
-
ALL (default): of measure that can be selected: mm, inch, D
-
nodEG : of measure that can be selected: mm, inch
- OFF : the key is disabled and does not allow changing the selected measuring mode.
To program the parameters listed above, see paragraph 8.2.
7.3 Setting the absolute reference
After having selected the absolute measuring mode and stopped the shaft in
the starting position or in the reference position, press the key combination
to set the absolute value to the sum of the values of the parameters
OrG
(absolute value of reference) and OFFS (compensation value).
The value of compensation (offset) allows you to adjust the value shown on the
display in such a way that takes into account, for example, wear or tool change.
The system allows you to store up to 10 values of compensation. Press the key
combination + . The screen will display the last compensation value
used (eg OFS 0 ). Choose the desired compensation value by pressing the
key , and then press the key to confirm.
SThe screen will display the absolute value to the sum of the values of the
parameters
OrG and OFFS .
PTo program the offset values , see parameter
OFFS of paragraph 8.2.
It is possible to change the function of the keys
combination by setting the parameter
0_0__
The available options are:
-
L_OrG : the reference value and the compensation value are set as shown
above. Choose the desired offset among the 10 available values, then press
the key to confirm;
-
OFF : the keys combination + is not associated to any function
in the operating mode
For programming the parameters listed above see paragraph 8.2.
7.4 Direct programming of the absolute reference value (source)
– of the compensation value (offset)
– of the reading after one revolution
The function of the keys combination allows direct access to the programming
of one of the following parameters, depending on the value assigned to
parameter
0___0 .
The available options are:
-
P_OrG : direct programming of the absolute reference value ( OrG
parameter)
-
P_StP : direct programming of the reading after one revolution ( StEP
parameter)
-
P_OFS : direct programming of the compensation value ( OFFS parameter)
-
OFF : the keys combination +is not linked to any function in the
operating mode
For programming the parameters listed above see parameter
0___0 of
paragraph 8.2.
7.5 Battery replacement
The internal lithium CR2450 – 3.0 V battery ensures over 5 years battery life.
The symbol is shown on the display when the battery replacement is
required.
The replacement is made by simply removing the front cover without
disassembly of the indicator from the control shaft and keeping unchanged all
the configuration parameters.
To simply remove the battery from the battery compartment, we recommend
the use of a magnet.
