21.0 TROUBLESHOOTING GUIDE
21.1 If you encounter difficulties in getting a TPCMQ48 module or complete power system
to operate properly please check all connections carefully and use the following as a
troubleshooting guide.
a) If the INPUT GOOD LED is ON, the OUTPUT GOOD LED is OFF and there is no
voltage on the output then the unit will be inhibited. To enable the unit make sure that
the Inhibit input is connected to the +5V Standby supply.
b) If the INPUT GOOD LED is ON, the OUTPUT GOOD LED is OFF and the voltage
on the output is low then the output has been set below the DCOK detection point. If
the remote adjust feature is being used ensure that the control voltage is set at a level
sufficient to bring the output voltage within limits.
c) If both LEDs are OFF and the +5V standby supply is present then there is a fault with
the unit and it should be returned for repair.
d) If both LEDs are OFF and the +5V standby supply is present then the input supply is
not reaching the unit. Check that any breakers in the supply side have not tripped.
Please note that there are no user serviceable parts inside either the modules or the shelves and that
opening either will void the warranty.
