(c) Alert output accumulated pulse setting value, immediate stop accumulated pulse
setting value, and "Accumulated pulse setting" in the switch setting
The setting range of "
range of "
Cd.15
when the alert output accumulated pulses exceed the amount of "Accumulated pulse setting" in the switch
setting, an alert is output according to the setting of "Accumulated pulse setting".
The above is applicable to "
" Immediate stop accumulated pulse setting value (minimum value)".
Cd.16
When the measured reference value (maximum value) is 2000 and the setting values are as follows:
Ex.
• "Accumulated pulse setting" in the switch setting: -3700 to 3700 [selection 1]
• Alert output accumulated pulse setting value (maximum value): 3000
Cd.13
The calculated value of alert output accumulated pulses (maximum value) is 5000 (2000 + 3000).
However, the value of alert output accumulated pulses (maximum value) becomes 3700 because the
calculated value exceeds the amount of "Accumulated pulse setting"
(3) If " Accumulated pulse setting value selection" is set to "1: Set with
Cd.17
magnification"
Alert output accumulated pulses and immediate stop accumulated pulses can be obtained as follows:
Alert output accumulated pulses = reference value + (Alert output accumulated pulse setting value - 1000) ×
reference value  1000
Immediate stop accumulated pulses = reference value + (immediate stop accumulated pulse setting value -
1000) × reference value  1000
Last three digits of the setting value indicate the value after the decimal point.
When the alert output accumulated pulse setting value is 1234, the alert output accumulated pulses can
Ex.
be obtained by multiplying the reference value by 1.234.
(a) When the value is outside the setting range
The accumulated pulse error detection function does not operate.
(b) Alert output accumulated pulse setting value and immediate stop accumulated
pulse setting value
The value of alert output accumulated pulses (maximum value) is calculated using the value of
" Immediate stop accumulated pulse setting value (maximum value)" at the following condition:
Cd.14
" Alert output accumulated pulse setting value (maximum value)" > "
Cd.13
pulse setting value (maximum value)"
The value of alert output accumulated pulses (minimum value) is calculated using the value of
" Immediate stop accumulated pulse setting value (minimum value)" at the following condition:
Cd.16
" Alert output accumulated pulse setting value (minimum value)" > "
Cd.15
pulse setting value (minimum value)"
228
Alert output accumulated pulse setting value (maximum value)" is 1 to 148000 (the
Cd.13
Alert output accumulated pulse setting value (minimum value)" is -148000 to -1). However,
