Note1. Faston terminals have a locking function.
Press the tab in the middle of the terminals to remove them.
Check that the terminals are securely locked in place after insertion.
Note2. Remove the short circuit wire between the terminals K10 and K11 to connect a flow switch.
Note3. Be sure to connect the wires from terminals K4 and K6 to the interlock contact on the pump.
A short-circuit may cause abnormal stop or malfunctions.
Note4. Operation signals can be received from through the No-voltage contact.
Note5. Use a 4-20mA signal output device with insulation.
Feeding 30mA or more current may damaged the circuit board.
Note6. Make sure that on site terminal connection is correct.
With wrong connection,operation error may occur.
Note7. Leave a space of at least 5 cm between the low voltage external wiring (No-voltage contact
input and remote controller wiring) and wiring of 100V or greater. Do not place them in the
same conduit tube or cabtyre cable as this will damage the circuit board.
The specification of the product might be changed without a previous notice for the improvement.

Note8. When cabtyre cable is used for the control cable wiring,
use a separate cabtyre cable for the following wiring.
Using the same cabtyre cable may cause malfunctions and damage to the unit.
(a) Optional remote controller wiring
(b) No-voltage contact input wiring
(c) No-voltage contact output wiring
(d) Analog input wiring
Note9. Use a contact that takes 12VDC 1mA for No-voltage contact input.
When a power supply voltage of 380 V, 400 V, or 415 V is applied, the output
voltage of 200 VAC, 230 VAC, or 240 VAC will be output from the dry contact
respectively. Use the unit in between the 10 mA and 1 A range.
