4. MEASURING PROCEDURE
Terminal layout Fig. 2
4-1 Terminal connection
1)Input the ACV power ( 90 to 260 ACV ) to T1, T2.
Do not input the
over voltage to the
AC input terminals.
2)Connect the " Control Relay " output from T3, T4.
Connect the " Alarm Relay " output from T5, T6.
3)Connect the following optional sensor ( or similar sensor ).
* Proximity sensor, PX-01.
* Photo sensor, PI-06.
to the input terminal T8, T9, T10.
T8 is DC 12 V power supply terminal.
T9 is the ground ( - ) terminal.
T10 is the pulse input terminal.

4-2 RPM measurement
1)Power on the meter, the " Display " ( 3-1, Fig. 1 ).
2)Press the " Function Button " ( 3-7, Fig. 1 ) once until
the " RPM indicator " ( 3-10, Fig. 1 ) and the " PV
indicator " ( 3-2, Fig. 1 ) is lit.
The " Display " ( 3-1 , Fig. 1 ) will show the RPM value.
3) The RPM value equal :
Total input signal ( pulse ) per min.
÷ ( divide )
setting pulse no. per round
For example :
If the total signal ( pulse ) input per minute
is 5, 124, the setting pulse no. per round is 1,
the RPM value will be 5,124/1=5,124.
The procedures that to set the
*" Pulse no. per round "
refer to the page 10 " 4-5 2nd layer setting procedures ".
4-3 Surface speed ( m/min., ft/min. )
measurement
1)Power on the meter, the " Display " ( 3-1, Fig. 1 ).
2)* Press the " Function Button " ( 3-7, Fig. 1 ) once until
the " m/min indicator " ( 3-12, Fig. 1 ) is lit. The "
Display " ( 3-1 , Fig. 1 ) will show the m/min. value.
* Press the " Function Button " ( 3-7, Fig. 1 ) once until
the " ft/min indicator " ( 3-11, Fig. 1 ) is lit. The "
Display " ( 3-1 , Fig. 1 ) will show the ft/min. value.
* Under the surface speed measurement, the
" PV indicator " ( 3-2, Fig. 1 ) will light too.

3) The m/min. value equal :
Total input signal ( pulse ) per min.
÷ ( divide )
setting pulse no. per round
x ( multiple )
setting roller diameter ( cm )
x ( multiple )
3.14
÷ ( divide )
100 1 meter = 100 cm
For example :
If the total input signal ( pulse ) per minute
is 501, the setting pulse no. per round is 1,
the roller diameter is 10 cm
the m/min. value will be 501/1x10x3.14/100=157.3
The ft/min. value equal :
Total input signal ( pulse ) per min.
÷ ( divide )
setting pulse no. per round
x ( multiple )
setting roller diameter ( cm )
x ( multiple )
3.14
÷ ( divide )
30.48 1 ft = 30.48 cm
