ASL Amplifier Mainframe Commissioning

Please refer to the Amplifier Mainframe, Amplifier, and Interface Card user documentation to
complement the information provided in the following sections.
6.1
Detecting Frames Using ‘Learn’ Mode
The ‘Learn’ function allows the system to automatically detect all ASL amplifier mainframes and amplifiers
which are connected to the VAR Router. Once the system has detected the installed configuration, each
mainframe configuration will be available for viewing, and the user will be able to commission the detected
mainframes.
The act of commissioning commands the mainframe to recognise the current amplifier installation as the
correct one, e.g. if an amplifier is removed and no longer required, then a fault will be reported that the
amplifier is not present until the mainframe is re-commissioned. Once re-commissioned the mainframe will
recognise that the missing amplifier is correctly missing, and will stop reporting a fault.
In order to learn and commission the current amplifier installation proceed as follows.

LEARNING – FRAME/AMPS – 02/007 (10s)
Please wait…
Remaining time for detecting frames
Total number of amplifiers detected
Total number of mainframes detected
Note:
The VAR Router will lock out the user whilst each amplifier mainframe is interrogated in turn.
The total number of mainframes and amplifiers currently detected are displayed on the top
display (mainframes/amplifiers). The example above, 02/007, indicates that a total so far of 2
mainframes and 7 amplifiers have been detected.
The display is updated as each mainframe is detected. The time remaining for detecting
mainframes will be displayed on the top display line, counting down from 10 seconds.
2. At the end of the countdown, the mainframe commissioning menu is displayed for each mainframe:
[F02 100D - 100N 100S]
Surveillance mode
Amplifier rate
Mainframe number
Slot 4
Slot 3
Slot 2
Slot 1
Default values: n.a.
Note:
If no mainframe is detected, then the ‘NO CONFIGURED FRAMES’ message will be displayed.
‘S’ identifies a standby amplifier, e.g. Slot 4.
‘N’ identifies a single circuit surveillance mode, e.g. Slot 3
‘D’ identifies a dual circuit surveillance mode, e.g. Slot 1.
‘L’ identifies a loop return surveillance mode.
‘
−
’ indicates that the slot is not configured, e.g. Slot 2.
