Faults without Fault Messages
There are several possible failure modes that render the Executive processor and the
Serial Control Panel inoperative. Failure of these systems will not result in any help-
ful hints about the possible source of failure. This section lists the known failures that
will render the RLS inoperative without telling you why.
6.1.1
When the power is turned on: no motion occurs, the LCD does not il-
luminate, the three power-indicating LEDs on the IPM (rear of RLS) are
dark.
1.
Check that the power source is live.
2.
Check the line fuse in the Power Supply Module (remove power cord(s) first).
3.
Check the action of the Power Switch. It should possess a definite latching feel
at the end of its travel. The sliding linkage on the right inside of the RLS could
be binding due to shipping damage or a foreign object.
6.1.2
When the power is turned on: no motion occurs, the LCD does not
illuminate, the +24V LED on the IPM (rear of RLS) blinks.
1.
A component failure has occurred on a PCBA that causes an excessive load on
the power supply.
2.
The Power Supply Module has failed.
6.1.3
When the power is turned on: the LCD is illuminated and shows the li-
brary model number, no errors messages are displayed, and nothing
moves.
1.
The Front Panel/Door is ajar. It is not completely closed. It may appear to be
closed, but is not completely latched.
2.
The Door Latched Sensor is not functioning.
