Analog Output Wiring; Pulse Output Wiring; Status Input Wiring; Modbus (Rs-) Wiring - Oval ALTI mass Series Instructions Manual

6.5.1 Analog output wiring

When a receiver is connected to the analog output ( to 0mA) terminal, connect analog output  to
terminal "ANALOG+" and terminal "ANALOG-", and connect the analog output  to terminal
"ANALOG+" and terminal "ANALOG-" .
Maximum load resistance is 00Ω.

6.5.2 Pulse output wiring

When a receiver is connected to pulse output, connect the pulse output to terminal "PULSE +" and
terminal "PULSE -".
The transmission distance may be restricted depending on the output frequency.
(This value is decided based on the wiring material whose cross-sectional area is 0.7sq.)
Pulse output transmission distance
The open drain pulse output and the voltage pulse output can be switched by the switch as shown in the
figure below.
The voltage pulse is the drain terminal of open drain pulse pulled up by resistance.
The logic of output is "ON = Lo, OFF = High" same as that of open drain pulse.

6.5.3 Status input wiring

When using the Status Input / Output, please connect to the "STATUS I/O +" terminal and the
"STATUS I/O -" terminal.
Status Input / Output can be switched at the parameter setting.
6.5.4 Modbus (RS-485) wiring
For the Modbus communication type, please connect the communication signal wire to the "RS- +"
terminal and the "RS- -" terminal. It is recommended to use a twisted pair cable with the wire
diameter of 0.7mm . The maximum cable length is 00m (Length depends on operating conditions).
