Circuit 2
Note 1
Circuit 1
Circuit 3
Note 1
Uses the external power supply.
For future expansion. Never turn to ON, otherwise an operation
error occurs.
Uses internal power and +5V power supply (max. 100 mA)
Separates between the internal and external grounds.
Connects between the internal and external grounds.
Note 1: Settings of Circuits 2 and 3 should be identical, disregarding it is ON or OFF. These two circuits do
not function if inconsistently set (disregarding ON or OFF).
NOTE Circuits 2 and 3 of the DIP switch
Do not turn the circuits 2 and 3 to ON as much as possible except when it is un-
avoidable because any external power supply can not be used. If doing so, malfunc-
tion may occur due to electrical interference.
