Fault Philosophy - PEAK COMMUNICATIONS P7001R Installation And Operating Handbook

1.7 Fault philosophy

Fault conditions are divided into two categories;
a) MAIN UNIT COMMON FAULTS; Faults with internal items that effect the
overall unit (Main power supply assembly etc).
b) DEVICE SPECIFIC FAULTS; Faults that are specific to the Up or
DownConverter assemblies. These can include external fault inputs.
Most faults as shown below activate the summary ALARM on the unit, this will force
a change-over if used in a normal redundant system.
The only fault that does not cause the unit to go into ALARM is the 'External Mute'.
All faults shown below are reported the remote interface and turn the tri-colour fault
LED to red.
Green – No faults
Amber – Unit in standby
Red – Fault condition
The MUTED column shows if the output is muted when the ALARM is active.
