5. FUNCTION AND DATA SETTINGS
5.5.10 Alarm Output at Low Flow Limit (Flow Switch)
• In case flow rate decrease under set level, an status signal is output.
PLS/ALM+, PLS/ALM– terminals are for common use with pulse, alarm and other
status output functions. Therefore, in case this function is used, other functions are not
available to use.
Alarm output at low flow limits can be selected “04” in
parameter No. “b10”.
The Low Limit value can be set in parameter No. “b36”
as parcentage for 4 to 20 mA.
Hysteresis width is set in parameter No. “b37”.
When using reversed status (ON/OFF) is required,
it can be set in
“N02 Output Mode”.
