The current ATM threshold setting
• can be read / written via the diagnostic port
• is output at the measurement signal output instead of the
pressure signal, can be measured with a voltmeter, and is
displayed on the LCD display after the <SP1> or <SP2>
button is pressed
• can be read / written via the DeviceNet, Profibus and RS485
interface.
DANGER
DANGER: malfunction
If processes are controlled via the signal output,
keep in mind that by pushing the <SP> button the
measurement signal is suppressed and the cor-
responding threshold value is output instead. This
can cause malfunctions.
Push the <SP> button only if you are sure that no
damages can arise from a malfunction.
