The pump proportionally doses at a signal of 20-4(0) mA. By default, the
pump interrupts the dosage at 20 mA and doses at the maximum set
frequency when it receives 4 mA. For an input signal of less than the
minimum value – 0.2mA (fixed threshold) (Ex. 4-0.2= 3.8mA) the alarm
LED turns on to indicate that the minimum value has been exceeded, but
the pump continues to dose at the maximum frequency. These two values
can be modified during programming. The maximum frequency can be
modified during operation by pressing
+ simultaneously to
modify the flow rate.
To view the current reading for the mA input, scroll the menu items to In
mA.
For an input signal of less than 0.2 mA the alarm LED turns on to indicate
the absence of signal and the pump interrupts the dosage.
