Reset Button
Press and hold the reset button for more than 2 seconds after the unit starts running properly,
and wait until ENET ERR LED blinks. The default parameters are shown below, the settings will
take effect after cold reset.

NOTE:
Make sure that all local and national electrical standards are met when
installing the unit. Contact your local authorities to determine which codes apply.
Power
Use power output that meets SELV (Safety Extra-Low Voltage) requirements. The unit can be
powered by DC power only, voltage range: 24VDC (-15%/+20%), compatible with most
controller DC systems. The power conditioning circuitry inside the unit is accomplished by a
switching power supply. The peak starting current can be as high as 2A.
Fusing Require-
ments
If the Power LED does not light up immediately after power up, remove power. A resettable
fuse will protect against overcurrent faults in DC circuit and the resetting will take place after a
period of time. Check wiring for proper connections and try to power up again.
High Voltage
A resettable fuse will prevent damage for overcurrent condition however it isn’t guaranteed.
DC voltage sources should provide proper isolation from main AC power and similar hazards.
Emergency Stop
A Hard-wired EMERGENCY STOP should be fitted in any system using the product.
Supply Voltage
Condition
Do not power the unit and inductive DC loads, or input circuitry to the controller, with the same
power supply. Note: The 24 VDC output from some controllers may not have enough current to
power the unit.
Wire Routing
a. Power wire length should be minimized (Max: 500m shielded, 300m unshielded).
b. Please use twisted pair cables for power wire and signal wire and conform to the
impedance matching.
c. If wiring is to be exposed to lightning or surges, use appropriate surge suppression
devices.
d. Keep AC, high energy, and rapidly switching DC power wiring separated from signal wires.
e. Add a resistor and capacitor in the parallel connection between the ungrounded DC power
supply and the frame ground. This provides a path for static and high frequency
dissipation. Typical values to use are 1M Ohm and 4700pF
Hardware
Considerations
The system designer should be aware that devices in Controller systems could fail and
thereby create an unsafe condition. Furthermore, electrical interference in an operator
interface can lead to equipment start-up, which could result in property damage and/or
physical injury to the operator.
If you use any programmable control systems that require an operator, be aware that this
potential safety hazard exists and take appropriate precautions. Although the specific design
steps depend on your particular application, the following precautions generally apply to
installation of solid-state programmable control devices, and conform to the guidelines for
installation of Controllers recommended Control Standards.
Programming
Considerations
Checks should be placed in the controller to ensure that all writable registers that control
critical parts of plant or machinery have limit checks built into the program, with an out-of-limit
safe shut down procedure to ensure safety of personnel.
