- Accura 2300[S] stands for Accura 2300 or Accura 2300S.

- DCM module is a shorthand notation for Accura 2350-DCM module.

You can connect DCM module to Accura 2300[S] with communication line and use the LCD screen of Accura

2300[S] to check the measurement values of DCM module or to set up the settings conveniently. Accura 2300

and Accura 2300S have no functional differences in their operation with DCM module, and the LCD display

screen sequence and segment display are slightly different.

DCM-500V module can only work with Accura 2300[S] via communication line(link-operation). DCM-50V

module can work with Accura 2300[S], and can also be operated alone(stand-alone operation).

Power Cable Connection

DCM module detects the voltage across the +/- bus bar and the current through the + bus bar. Therefore, the

current flowing on both bus bars and the current flowing only on + bus bar are possible.

Communication Line Connection

To operate DCM module with Accura 2300[S], connect RJ12 communication line to RJ12A and RJ12B ports.

DCM module receives control power through communication line. In case of stand-alone operation in which

Accura 2350-DCM-50V module does not connect communication line, the control power is supplied by bus

bar DC voltage.

Fig 1.8 Communication Line Connection

Note

The power consumption of Accura 2350-DCM module is triple that of Accura 2350-3P three-phase power

measuring module. Therefore, the number of Accura 2350-DCM modules that can be connected to Accura

2300 or Accura 2300S is limited to total 10 modules, 5 modules each for RJ12-1 and RJ12-2 port.

4. The measured value below the configured minimum measurement is treated as zero.

5. Current measurement values may contain errors as the temperature varies.

6. Over event occurs when the measured value exceeds threshold 1by time delay.

Sampling

Voltage and current are sampled every 1ms.

20ms aggregation

Every 20ms, N data of 1ms resolution are averaged to generate voltage/current data of 20ms resolution. The

averaging number N is user configurable from 1 to 32, with default 20. The obtained voltage/current data of

20ms resolution is used to monitor over/under event.

aggregation data of one second or more. For more than 1 second aggregation data, refer to the aggregation

Event block per channel is shown in Figure 2.4 and DCM module supports five channel event blocks.

Select the input signal from voltage and current, and select the event type from Over/Under. Voltage/Current

data to be monitored is data of 20ms resolution obtained by N average of 1ms sampling data. The event is

divided into a start event and an end event. A detailed description of the event is described in the table below.

Item

Description

Event type

Off / Over / Under

Monitoring signal

Choose between voltage and current.

Start level

Event threshold 1 level

Residual level

Event threshold 2 level, used only in under event. The start event for under event occurs only if the

monitoring signal is above the residual level, and is less than the start level for time delay.

Hysteresis

If the measured value repeats a frequent rising and falling of the event start level, a lot of events

may occur. Therefore, proper hysteresis setting is necessary for effective event management.

Hysteresis setting is not supported on LCD screen of DCM module and can only be set by

communication. Default value is 2% of rating. For details, refer to Communication Setting section.

End level

In case of over event, end level is obtained by subtracting hysteresis from threshold 1 level. In case

of under event, end level is obtained by adding hysteresis to threshold 1 level.

Time delay

When the start level is exceeded and the time delay elapses, a start event is generated. If the start

level is exceeded but is not maintained for time delay, the start event does not occur.

Start event

When the monitoring signal exceeds start level in over or under direction, a start event occurs when

the time delay elapses. The event LED is blinking by the start event, and DO is also activated when it

is set to DO link-operation.

End event

If the monitoring signal is recovered within the end level with the start event occurring, an end event

occurs. The event LED is not turned off by the end event but is turned off only by the user SET button

input. If the DO is linked to the event, the DO is also cleared with the user SET button.

Event Alarm Generation

Event alarm is provided when a start event occurs. The basic event alarm is the blinking of the event LED and

the blinking of LCD screen to display the event contents. Additional event alarm is digital output (DO) contacts.

This additional digital output contact alarm can be enabled and is off by default.

Event Alarm Clear

If the user presses the SET button for more than 1 second, the event alarm is cleared. When the event alarm is

cleared, the display returns to the display mode, the event LED turns off, and the linked digital output contact

is also cleared.

Note

To clear the event alarm, press EVENT button on Accura 2300[S]. If you confirm the event log with EVENT

button of Accura 2300[S], event alarm of Accura 2300[S] and event alarm of DCM module are also cleared.

However, releasing the event alarm with the SET button of DCM module clears only the event alarm of DCM

module, but does not clear the event alarm of Accra 2300[S].

Event Alarm Auto-Clear

Event alarm auto-clear function is basically blocked and can be set from 1 minute to 999 minutes. After the

event alarm occurs, it is automatically cleared when the auto-clear time elapses.

Under Event

Under event is generated when the monitoring signal falls below the start level(threshold 1) and over the

residual level(threshold 2) by time delay. If the residual level is abnormally configured above the start level, the

residual level is considered to be zero.

Figure 2.8 shows the case where the monitoring signal is over the residual level and figure 2.9 shows the case

where the monitoring signal is below the residual level. Under event does not occur if it falls below the residual

level from normal state within time delay. When the residual level is set to 0, it operates only by the start level.
