The minimum voltage value up to the present time.
A phenomenon of repeatedly turning ON and OFF the switch output at high
frequencies.
The sensor monitor at the copy source when using the copy function.
A function to copy function settings (excluding settings related to the
operating range).
The sensor monitor at the copy destination when using the copy function.
The setting time from when the signal of the connected analogue ASW
reaches the set value to when the ON-OFF output actually begins working.
Setting the delay time can prevent the output from chattering.
The range between the maximum and the minimum peaks in the analogue
output waveform when an analogue ASW is mounted to the cylinder, etc.
In this range, the magnet position is uniquely determined for an analogue
value. (Refer to page 21)
An increment of voltage display digit on the sensor monitor, indicating how
precisely the voltage can be displayed or set. When 1 digit = 2 [mV], the
value is displayed in increments of 2 [mV], e.g., 2, 4, ..., 98, 100.
A function to add a digital filter to fluctuations in the output signal of the analogue
ASW. The function moderates fluctuations in the indicated value in response to a
sharp rise or fall of the signal. When the function is used, digital filtering applies
to switch output ON or OFF and the analogue response time. Output chattering
or flicker in the measurement mode display can be reduced by setting the digital
filter.
It is 90% response time in relation to the step input.
An extent of error between the output voltage of the analogue ASW and the
displayed voltage value.
The colour of the digits on the digital display.
The display can be selected from four patterns: always green, always red,
green (switch OFF) changing to red (switch ON), or red (switch OFF)
changing to green (switch ON).
The number of divisions the rated range can be divided and displayed.
Example: If the rated range can be displayed in a 2-mV increment, the
resolution is 2/4000.
A code displayed on the sensor monitor indicating non-conformance that may
cause the switch to fail detected by the self-diagnostic function of the product.
Refer to "Error Display Function" on page
A mode used to set various functions. When using the product by changing
the settings from the factory default, each setting can be selected using "F."
Specific settings include the operating range setting, display colour, output
type, output setting mode, digital filter, display resolution, whether or not to
use energy saving mode, and whether or not to use a security code.
