Table 2: Top Right Generic Icons
The ‘PSA Loop’ icon flashes when a PSA test is occurring and shows that a change in state may happen.
The flashing will occur a few second after PSA to ensure the user notices any changes especially if it is a
short PSA.
A partly working PSA loop can happen if there is an S-line connection fault or V-line connection fault. If both
lines have a fault, then the unit cannot see the PSA controller and will display an un-tested PSA icon.
See System Test section below.
Text Box
The text box area of the screen provides the user with text information referring to the operation of AMBA4.
For example, it displays ‘SPEAK’ when the speak key is pressed or ‘LOW LINE VOLTAGE’ when the R-line
voltage is low.
