Subtask 73-25-34-860-088-A ** ON A/C NOT FOR ALL

A. DISCRETE OUTPUTS P TYPE

ACTION	RESULT
1.Push the line key adjacent to the EIU1(EIU2) indication on the MCDU.	The EIU1(EIU2) menu comes into view.
2.Push the line key adjacent to the TESTS indication.	On the MENU page, the TEST menu comes into view.
3.Push the line key adjacent to the SPECIFIC DATA indication.	On the MENU page, the SPECIFIC DATA menu comes into view.
4.Push the line key adjacent to the DISCRETE OUTPUTS SIMUL indication.	The DISCRETE OUTPUTS SIMUL menu comes into view.
5.Push the line key adjacent to DISCRETE OUTPUTS P TYPE indication.	The DISCRETE OUTPUTS SIMUL (P TYPE: 28VDC/OPEN) menu comes into view. On page 1: APU BOOST CMD1 APU BOOST CMD2 OLP AND GND1 OLP AND GND2 On page 2: LIGHT FAULT ON. NOTE: When the DSO type P commands an electrical 28 VDC, then the status displayed shall be 1. When the DSO type P commands an electrical open circuit, then the status displayed shall be 0. When the DSO type P is failed, then the status displayed shall be a dash (-).
6.On the MCDU, push the line key adjacent to the RETURN indication until the CFDS menu page comes into view.
7.Stop the MCDU.
