Display Options Module
The Display Options module is a core module that cannot be deleted, copied, or linked. It is configured by altering the contents of its setup registers.
The Display Options module has no inputs.
This register holds the number of seconds that a screen remains on the front panel display before scrolling to the next screen.
This register specifies how the power factor data is labeled.
This register determines how groups of three digits are separated.
This register determines how the date is shown.
This register determines the number of decimal places of accuracy that voltage readings display.
This register determines the number of decimal places of accuracy that current readings display.
This register determines the number of decimal places of accuracy that power and energy readings display.
This register holds the global contrast setting for the meter display.
This register holds the number of seconds that the backlight of the front panel display stays on after the last press of a front panel button.
This register controls how frequently the screen data values are updated.
This register controls whether or not the display time value should reflect daylight savings time (DST).
This register determines the minimum time allowed between consecutive demand resets.
Any Display module that is set to display scaled parameters (see the Display module's Screen Type setup register) divides or multiplies its parameters by this Display Scaling Factor before displaying them. Scaling by division or multiplication is selected in the Display Scaling Mode.
This register specifies whether parameters are divided or multiplied by the Display Scaling Factor before displaying them. Division is the default.
This register defines whether or not to allow meter configuration changes through the device's front panel. Some meters do not even show the meter's settings when this register is set to disallow changes.
This register determines how vector diagrams are displayed on the meter's front panel. Two settings are available:
Instrument (voltage vectors appear 60 degrees apart - showing the actual voltage and current values that the meter is measuring).
System (voltage vectors appear 120 degrees apart - showing true system operation including any calculated values).
This register only applies when the meter is in Delta volts mode. See the Detailed Operation section for more information.
This register holds the number of seconds that the device remains in TEST mode before automatically reverting to NORM mode. This timer resets if a front panel button is pressed or a setup register is altered.
This register controls whether or not the screens displayed on the front panel are programmable via Display modules.
This register controls which language is used to display information on the front panel. The default is English.
This register determines which set of measurement symbols are used on the front panel – IEEE (Vll, Vln, kW, kVAR, kVA) or IEC (U, V, P, Q, S).
This register determines what format time is displayed in on the front panel – 24 hour or 12 hour.
These registers determine the color of the current and/or voltage vectors on the remote display’s phasor diagram.
These registers determine the event priority that defines a medium or high event on the remote display’s event log screen.
These registers determine the event color on the remote display’s event log screen.
These registers determine the units applied to each type of measurement. To identify which values have these units applied, refer to the display and web units information on your meter’s Modbus map, available from www.se.com.
This register contains the time (in seconds) that elapses between successive screens for the normal mode displays. Setting this register to 0 (zero) stops the screens from auto-scrolling.
This register contains the time (in seconds) that elapses between successive custom display screens. Setting this register to 0 (zero) stops the screens from auto-scrolling.
All events are recorded in the Event register. Possible events and their associated priority numbers are:
|Event priority group||Priority||Description|
|Setup Change||10||Setup registers or labels have been changed.|
The Event output register stores the following information for each ION event: time stamp, priority, cause, effect, and any values or conditions associated with the cause and effect.

Delta Vector Display Type
Diagrams 1 and 2 below illustrate how the vector diagram (phasor) is displayed depending on the value of this setup register.
For the wiring diagram illustrated above, the vector diagram (phasor) is displayed as shown below in Diagram 2. If the Delta Vector Display Type is set to system, the vector diagram is displayed as per the figure on the left. The figure on the right corresponds to the instrument setting.
