ANA. V (analogue variable) programming (see page 42 & 54)
The pump increases/decreases a stroke/flow rate in proportion to 0-20mA. Determine the operational behav
-
iour by programming two set points and choosing one of the LINEAR, BOX and LIMIT patterns.
To show the current value, push the key. To return to the flow rate display, push the key.
<LINEAR>
A stroke/flow rate changes with a current value by a programmed line.
Condition:
Set Point 1 (SP.1) = Ampere : 6mA, Flow rate : 90L/H
Set Point 2 (SP.2) = Ampere : 17mA, Flow rate : 255L/H
<BOX>
A stroke/flow rate changes with a current value by a programmed line. The rate does not exceed the Set Point
2 but then falls to 0 before the Set Point 1.
Condition:
Set Point 1 (SP.1) = Ampere : 6mA, Flow rate : 90L/H
Set Point 2 (SP.2) = Ampere : 17mA, Flow rate : 255L/H
<LIMIT>
A stroke/flow rate changes with a current value by a programmed line. The rate does not falls below the Set
Point 1 or exceed the Set Point 2.
Condition:
Set Point 1 (SP.1) = Ampere : 6mA, Flow rate : 90L/H
Set Point 2 (SP.2) = Ampere : 17mA, Flow rate : 255L/H
