<SET> button

The <SET> button performs the following functions depending on mode:

Operating mode

The EFB300 external function box is in operating mode during operation. Operation of the EFB300 is indicated by steady illumination of the LED labeled "ACT".

If a tripped signal is present at an output (output is activated), the user can acknowledge the signal or reset the output. This can be done by various methods:

  • By application of a signal to the digital input of the EFB300

  • By brief actuation of the <SET> button on the EFB300

  • By actuation of the <ESC> button on the ETU

LED states in operating mode

Simultaneous flashing of all LEDs indicates that the EFB300 is defective.

Test mode

All inputs and outputs can be activated or deactivated manually in test mode. This can be done to determine whether the digital outputs and the ZSI bus are functioning properly and wired correctly.

The LED labeled "ACT" flashes to indicate that test mode is active. The powerconfig software can also be used to test outputs.

Activating test mode and performing tests

  1. In order to activate test mode, press the <SET> button for at least 2 seconds ① until all the LEDs for the outputs light up briefly ②. Test mode is activated when the LED labeled "ACT" starts to flash ③.
