Device Functionality
3.2 Device Configuration
Parameter: Active Group
•
Default Setting: 1 (Gn1)
The relay provides 4 groups of function settings – Group number (Gn) 1 to 4. At any 1 time only 1 group
of settings can be active – Device Config > Active Group setting. An output is provided to indi-
cate which setting group is active.
It is possible to edit 1 group while the relay operates in accordance with settings from another active
group using the View/Edit Group setting.
Some settings are independent of the active group setting i.e. they apply to all settings groups. This is
indicated on the top line of the relay LCD – where only the Active Group No. is identified. Where
settings are group dependent this is indicated on the top line of the LCD by both the Active Group
No. and the View Group No. being displayed.
A change of settings group can be achieved either locally at the relay fascia, remotely over the data
comms channel(s), or from a binary input. When using a binary input an alternative settings group is
selected only whilst the input is energized (Select Grp Mode: Level triggered) or latches into the selected
group after energization of the input (Select Grp Mode: Edge triggered).
Different settings groups may be selected to provide more appropriate settings e.g. when the network is
reconfigured, during periods temporary overload or during emergency operating conditions.
Settings are stored in non-volatile memory.
Parameter: View/Edit Group
•
Default Setting: 1 (Gn1)
Settings in the selected group (Gn) can be viewed and edited where required.
Parameter: Setting Dependencies
•
Default Setting: Enabled
When enabled the relay displays settings information for the enabled functions only.
This reduces the amount of information in the settings screens as the functionality not being used is not
shown. Using setting dependencies provides clearer information to the user as only available function-
ality is visible.
Parameter: Favorite Meters Timer
•
Default Setting: 60 mins
The device displays the favorite meters selected by the user when the device has been inactive for a
period in excess of the timer setting. Favorite meters are selected by viewing the relevant meter and
pressing the Enter pushbutton. Favorite meter selection is cancelled by again selecting the meter and
pressing the Enter pushbutton.
When several meters are selected as favorites each selected screen is displayed for 5 seconds.
Parameter: Backlight Timer
•
Default Setting: 5 mins
To conserve power the display backlighting is extinguished when no buttons are pressed for a user
defined period. This setting is used to adjust the timeout from 1 to 60 minutes and Off (backlight perma-
nently on).
NOTE

The LCD display automatically switches off when no buttons are pressed for 60 minutes.
Pressing any key will re-activate the display, (see
