LED TEST CONTROL
The test is initiated when the user-programmable pushbutton 1 is pressed. Keep the pushbutton pressed for as long as the
LEDs are being visually inspected. When finished, release the pushbutton. The relay then automatically starts stage 2. At
this point, test can be cancelled by pressing the pushbutton.
Application example 2
Assume one needs to check if any LEDs are "burned" as well as exercise one LED at a time to check for other failures. This
is to be performed via user-programmable pushbutton 1.
After applying the settings in application example 1, hold down the pushbutton as long as necessary to test all LEDs. When
finished, release the pushbutton so that the relay then automatically starts stage 2. When stage 2 is completed, stage 3
starts automatically. The test can be cancelled at any time by pressing the pushbutton.

 USER-PROGRAMMABLE
 LED 1
There are 48 amber LEDs across the relay faceplate LED panels. Each of these indicators can be programmed to illuminate
when the selected FlexLogic operand is in the logic 1 state.
For the standard faceplate, the LEDs are located as follows:
• LED Panel 2 — User-programmable LEDs 1 through 24
• LED Panel 3 — User programmable LEDs 25 through 48
For the enhanced faceplate, the LEDs are located as follows:
• LED column 2 — User-programmable LEDs 1 through 12
• LED column 3 — User-programmable LEDs 13 through 24
• LED column 4 — User-programmable LEDs 25 through 36
• LED column 5 — User-programmable LEDs 37 through 48
See the LED Indicators section in chapter 4 for information on the location of these indexed LEDs.
