How Do I Use DO Ports?

How Do I Use DO Ports?

The SmartLogger provides two DO ports, which support the reset of external routers, audible and visual alarming for grounding faults, and output of correlated alarms.

Before setting the corresponding function, ensure that the DO port is not set for other purposes. Otherwise, the setting will fail.

Resetting an External Router

Connect one DC power cable of the 3G router to a DO port on the SmartLogger, and power on or off the wireless module by connecting or disconnecting the DO dry contact to control the reset of the 3G router.

  1. Cut off a DC power cable of the router, and connect the DC power cable to a DO port on the SmartLogger.

    Figure 8-5 Connecting to a DO port

  2. Choose Settings > Other parameters and set Reset the external router to the DO port.

Audible and Visual Alarm for Grounding Fault

Connect one DC power cable of the audible and visual alarm to a DO port on the SmartLogger, and power on or off the audible and visual alarm by connecting or disconnecting the DO dry contact to implement audible and visual alarming for grounding faults.

  1. Connect one DC power cable of the audible and visual alarm to the DO port (COM/NO) on the SmartLogger.
  2. Choose Settings > Alarm Output and associate Low Insulation Resistance with the DO port.

Alarm Output

After a solar inverter alarm is associated with a DO port, the alarm signal is delivered from the DO port when the solar inverter raises the alarm.

  1. Choose Settings > Alarm Output and associate solar inverter alarms with the DO port.

    If the SmartLogger is restarted or powered off after the function is enabled, the DO port status may change and the alarm output may be abnormal.
