9.3.3 Configuration and adjustment
When optional alarms are fitted to a loop powered
indicator the configuration menu is extended as
shown in Fig 16. The additional functions appear
between the 5Et and the C--P functions for the
BA304G and between bAr and C--P for the
BA324G indicator. For simplicity, Fig 16 only
shows the additional functions for alarm 1, but
alarm 2 has identical functions.
The following table summarises each of the alarm
configuration functions and includes a cross
reference to more detailed information. Again only
the functions on Alarm 1 are listed, but alarm 2 has
identical facilities.
