ANA. R (analogue rigid) programming (See page 57)
The pump increases/decreases a flow rate in proportion to 0-20mA. Four (4-
20, 20-4, 0-20, 20-0) programs are provided.
In "4-20" or "20-4" program a disconnection sensor works to stop the pump
as a current value falls below 4mA ("DISCN" blinks on the screen). Check
wiring as necessary. Pushing the start/stop key, this state is released.
Condition
The left graph is in the following
programs.
a. 4-20 (Default setting)
b. 20-4
c. 0-20
d. 20-0
ANA. V (analogue variable) programming (See page 55)
The pump increases/decreases a flow rate in proportion to 0-20mA.
Setting two points can draw a straight line. Depending on the position of the
two points, 0 % may not come at 0mA in some cases. When a stroke rate
could become over 100% at some mA due to the setting, pump speed is lim-
ited to 100%.
Condition
The left graph is in the following
setting.
P1 = 6 mA, 30%
P2 = 17 mA, 85%
