TROUBLESHOOTING HINTS

A short circuit between different terminals of the installation will never damage the
connected systems.
O
Nothing operates:
w
Remember that the system remains inactive for 45 seconds after connecting the power
supply, the same occurs upon connecting any unit to the installation.
w
Check the output power supply voltage between '' and '+' terminals: it should have 17.5
to 18.5Vd.c. If not, disconnect the power supply from the installation and measure
again. If it's correct now, it means there is a short circuit in the installation. Disconnect
the power supply from mains and check the installation.
w
Check that 'A/D' terminal is not shortcircuited with '-' or '+' terminals.
