*5 When Dipswitch No. 7 is OFF (Normal Mode), a decrease in dilution N
an output on Pin No. 39. When Dipswitch No. 7 is ON (Dilution 0 Mode), this same
output on Pin 39 indicates that the dilution N
*6 Pins No. 2 (BP Start), 5 (BP Stop), 12 (BP Operation), 29 (BP Motor Temp.),
31 (BP Overload), 42 (BP Current) apply to Models A70W and A30W.

When using the RS232C communication port to monitor pump status, select a Data Length
of either 7 bits or 8 bits.
Dipswitch No. 2 configures observation of cooling water and N
"operating period only."
cooling water flow continues for 15 minutes after pump stops.
Dipswitch No. 3 selects Buzzer usage in ALARM / TRIP condition.
In remote mode, select pump operation "according to signal" or "automatically stop" with
Dipswitch No.4.
Do not wire vacant pins.
Apply 12V DC power for input signals on the pump side. Do
not apply this voltage on the equipment side.
The output signals are generated from an open collector
output. Apply a voltage not exceeding 50V DC on the
equipment side.
Wire all
(SIGNAL/COMMON).
When output signals energize an inductive load, such as a
relay, insert a diode (100V. 1A class) to absorb the back
electromotive force from surge currents.
