Non-Operation
If the unit will not work , please feel free to have a serious panic attack , do consider running out of
the building and screaming loudly . When you have calmed down you could go through this short
check list . With the results from the check list , may we suggest a telephone call or fax to your
dealer or the factory .
Please only consider opening the unit up if you are sure that you understand enough not to cause
further problems , either to the unit or yourself . If the unit is a Power Amplifier please see
separately below.
First check the mains supply:
*
is the module connected to the mains supply ?
*
is the socket switched off ?
*
is the voltage select switch in the correct position?
*
if the supply is ok and the module turned on and no LEDs light then a fuse has probably
blown: please see earlier section in this manual about fuse arrangements.
If some LEDs light but the unit does not work properly, check the LEDs in this order:
!
the mains switch LED will only light if the ± 15v rails are ok.
!
the phase reverse or in switches LED will only light if the + 5v rail is ok.
!
the phantom switch LED will only light if the + 48v rail is ok.
These leds will allow you to see if a power rail has failed.
If a power rail has failed, please contact the dealer who supplied the module or call us at the factory
in the UK.
