CHAPTER 7: COMMANDS AND TARGETS
A target enables the EnerVista UR Setup software to monitor automatically and display the status of any active target
messages of all the devices inserted into that site.
Each C30 element with a TARGET setting has a target message that when activated by its element is displayed in sequence
with any other currently active target messages in the
Element 48 target settings are active and so have their targets displayed. The down arrow below the two elements
indicates that there can be other active elements beyond these two.
For more information, see the description of target messages in the next section, and the Introduction to Elements section
in the Settings chapter for instructions on TARGET setting.
When no targets are active, the display reads

7.2.1 Target messages

When there are no active targets, the first target to become active causes the display to immediately default to that
message. If there are active targets and the user is navigating through other messages, and when the default message
timer times out (i.e. the keypad has not been used for a determined period of time), the display again defaults back to the
target message.
The range of variables for the target messages is described below. Phase information is included if applicable. If a target
message status changes, the status with the highest priority displays.

If a self test error is detected, a message appears indicating the cause of the error. For example UNIT NOT PROGRAMMED
indicates that the minimal relay settings have not been programmed.

7.2.2 Relay self-tests

7.2.2.1 Description
The relay performs a number of self-test diagnostic checks to ensure device integrity. The two types of self-tests (major
and minor) are listed in the following tables. When either type of error occurs, the Trouble LED Indicator turns on and a
target message displays. All errors record an event in the event recorder. Latched errors can be cleared by pressing the
key, providing the condition is no longer present.
RESET
Major self-test errors also result in the following:
The critical fail relay on the power supply module de-energizes
All other output relays de-energize and are prevented from further operation
The faceplate In Service LED indicator turns off
A RELAY OUT OF SERVICE event is recorded
To view error messages in EnerVista software:
