Wiring
Co unication wiring
SW power is supplied to the sensor connected to the input block. There is a voltage drop up
to maximum 1 V inside the SI unit when SW power is supplied. Select a sensor taking this
voltage drop into consideration. If 24 V must be supplied to the sensor, it is necessary to
increase the SW power supply voltage so that the input voltage of the sensor will be 24 V with
the actual load. (Allowable SW power supply range: 19.2 V to 28.8 V)

Bus cable and ter ination resistors
The cables, connectors, and termination resistors used in CANopen networks shall
meet the requirements defined in ISO 11898. In addition, here are given some
guidelines for selecting cables and connectors.
The table below shows some standard values for DC parameters for CANopen
networks with less than 64 nodes.
Switch setting
Before setting of Node-ID by DIP switch, turn “OFF” power supply to the SI unit.
Setting of Node-ID
Set SW7 to 0. (SW7 is not used.)
Set SW8 to 1. (fixed)

∗: Output numbers are assigned to stations from side D to U of manifold in order. (See manual of
each valve manifold for the directions of side D and U).
∗: Standard manifold is wired in double. Output numbers are assigned to side A and B alternatively.
In case of single solenoid valve, output on side B is free. (Refer to fig.a)
∗: ixed (single and double) wiring is available as long as wiring specifications designate it. This
allows output numbers to be specified without having free output. (Refer to fig.b)
∗: Each bit of data sent from master (4 bytes) shows ON/OFF (0: OFF, 1: ON) of solenoid valve.
Starting from LSB of the first byte (Offset0), output numbers are assigned to all the bits in
numeric order.

FE connection
Connect the ground terminal to the ground. Resistance to the ground should be 100 Ω
or less.
For drop cables a wire cross-section of 0.25 to 0.34 mm2would be an appropriate
choice in many cases.
Besides the cable resistance, there should also be considered the real resistance of
the connectors, if calculating the voltage drop. The read resistance of one connector
should be in the range of 2.5 to 10 mΩ.
