Application examples
TACMINA float switch
■
Stopping the pump when the tank has become empty
PW/PWM
(5) External stop signal
(6) COM
[Explanation]
(1) When the chemical liquid level in the tank drops, the contact signal of the float switch is set to ON.
(2) The pump remains stopped while signals (5) and (6) are ON.
The settings blink on the display.
■
Continuously operating more than one pump
The “solenoid sync pulse output” of the first pump is used for the signal input of the second pump.
(4) External signal
External signal
(6) COM
PW/PWM
PW
(7) Sync pulse output* (+)
(9) Sync pulse output* (–)
(6) COM
(4) Pulse input signal
First pump (controlled by external signals)
Second pump (operation linked)
* These signals are not the same as the external signals.
The pulse signal is output once per pump operation.
[Explanation]
(1) The first pump, which is a signal-input type, operates automatically by means of the external signals. (It can also
operate manually.)
(2) With the first pump, which is a signal-input type, the sync pulse signals are output to pins (7) to (9) with each pump
operation.
(3) With the second pump, which is a pulse signal-input type, the sync pulse output of the first pump is received as
external signals at pins (4) to (6).
(4) The second pump, which is a pulse signal-input type, arithmetically processes the signals received, and operates
for the number of times from 1/999 to 1x to 999x.
●
Operating the pumps at the same speed
The second pump, which is a pulse signal-input type, is set to 1 (1/1) in the pulse frequency-division mode or 1x in
the pulse magnification mode.
●
Operating the second pump once every time the first pump operates 5 times
Set the second pump, which is a pulse signal-input type, to the pulse frequency-division mode, and select the fre-
quency division to 5 (1/5).
●
Operating the second pump twice every time the first pump operates once
Set the second pump, which is a pulse signal-input type, to the pulse magnification mode, and set the magnification
to 2x.
(The control precision is reduced with this kind of setting so it is recommended that the pumps be installed in such a
way that the first pump operates for a greater number of times.)
