Explanation
Preset
• When you select a preset, settings appropriate for each signal are set automatically.
(You need to set a portion of the items.)
• The 10 presets below are available. For details on the settings of each preset, see
appendix 12.
Logic 5V, Logic 3V, Logic 12V, and Logic 24V
Use this preset when the output from the sensor changes in the range of 0 to 5 V (or 3 V, 12 V,
or 24 V: supply voltage applied to the sensor). The voltage range is automatically set to the
optimum voltage range, and the threshold level is automatically set to one-half the voltage.
Pull-up 5V
Use this preset when the sensor output is open collector or contact output. The pull-up setting on
the next page can be specified only when this preset is selected. The pull-up voltage is
approximately 5 V, and the pull-up resistor is 4.7 k
Ω
. If you turn pull-up ON, set the input voltage
in the range of 0 V to 5 V. If the input voltage exceeds this range, the protection circuit is tripped
and the pull-up resistor is automatically cut off.
ZeroCross
Use this preset when the input voltage changes around 0 V. The input coupling is automatically
set to AC, and the threshold level is automatically set to 0 V. Select the voltage range so that the
maximum amplitude of the input voltage is within the voltage range.
AC100V and AC200V
Use this preset when measuring the supply voltage of 100-V or 200-V power supply systems.
The probe type is automatically set to 10:1; the voltage range is automatically set to a value
suitable for the input voltage and probe factor; and the coupling is automatically set to AC. Be
sure to use the isolated probe (700929) when measuring the power supply voltage.
EM Pickup (Electromagnetic Pickup)
Use this preset when connecting the electromagnetic pickup directly. The voltage range is
automatically set to
±
1 V, and the threshold level is automatically set to 0 V.
User (User-Defined)
Use this preset when entering the input conditions arbitrarily. Pull-up cannot be specified.
Note
•
When measuring high voltage exceeding 42 V (AC+DCpeak) on the 701280 (FREQ), be sure
to use the isolated probe (700929).
•
Use EM Pickup only when connecting the electromagnetic pickup.
•
When set to EM Pickup, the LEDs of the frequency module do not illuminate in red even
when the range is exceeded.
•
The SL1400 does not support electromagnetic pickups that require power supply or those
that require terminators at the output. For these types of electromagnetic pickup, furnish
appropriate measures on the sensor end.
•
The output from the electromagnetic pickup must be within 42 V
P-P
. The minimum sensitivity
is 0.2 V
P-P
. If the output is less than the minimum sensitivity, the measured values may be
unstable.
•
When using the pull-up function, do not let the voltage exceed the 0 to 5 V range. If the
voltage exceeds the range, the protection circuit will be tripped, and the pull-up circuit will be
cut off.
