Wiring

iring of power supply

he Power supply connection inside the unit has individual power supplies for solenoid valve actuation (SV power supply) and for Sensor (SW power supply). Supply 24V DC for each of them. Either single or dual power supply is available. Wiring is not necessary for SW power supply when no Input Blocks are used. *

In case of single power supply, pay attention to the range of each

supply voltage.

f a sensor requires 24V, it is necessary to lower power supply voltage

or sensor slightly or secure a power supply for sensor separately without going through the SI unit so that sensor input voltage can be 24V with actual loading (allowable voltage of sensor power supply : 19.2V to

Node address and baud rate are preset to 63, 125kbps respectively at the shipment in either HWmode or SW mode.

2.In SW mode, setting value of address and baud rate are retained even

after power supply is off.

3.In HW mode, once power supply is turned off and turned on again,

then setting value of address and baud rate in S/W mode are erased. Address and baud rate can be set again by setting switch SW1.

Error Display Function

MOD/NET LED Cause & Countermeasure

Light OFF

PWR LED Light OFF <Countermeasure> Confirm that power for SI unit circuit is supplied. Confirm correct wiring for circuit. If above countermeasures do not improve status, please exchange SI unit.

PWR LED Light ON <Countermeasure> Confirm that baud rate is set correctly. If MOD/NET LED light is OFF in spite of baud rate is set correctly, exchange SI unit.

Green flashing

Connection waiting Shows communication waiting status between SI unit and master. <Countermeasure> Confirm master is operating correctly. If using scan list, ensure slave is recorded to scan list correctly.

Red flashing

Communication wire disconnected error Warning for SV supply voltage drop (Except for EX250-SDN1-X102) <Countermeasure> Confirm communication wire is connected. Confirm SV power supply voltage is according to specification. (21.6 to 26.4V) (Except for EX250-SDN1-X102) <Remark> Red flashing if master power source is turned off during communication.

Red Light ON

Node address overlapping error <Countermeasure> Confirm there is no overlapping on the node address.

BUS OFF error Detects communication error. <Countermeasure> Case 1 Communication error due to noise. Confirm there is no component or high voltage cable that generates noise around communication wire. Make some distances between communication wire and noise source. Case2 Communication cable problem Confirm terminal resistance (121ohm) is connected to both ends of DeviceNet communication wire.

If red MOD/NET LED is still ON despite above countermeasures, exchange SI unit.

When red MOD/NET LED is ON, even if cause is solved, the SI unit does not perform auto-recovery. In this case, please reset the power to SI unit circuit (Communication/Internal power supply).
