Diagnostic Leds - Siemens SIMADYN D T400 Brief Description

Technical data

3.8. Diagnostic LEDs

Three diagnostic LEDs are located on the T400.
LED H1 displays the status of the internal T400 monitoring
function. Under normal operating conditions it flashes slowly,
approximately every second (1.5 Hz).
If H1 starts to flash at a average rate (with 2.5 Hz) this indicates an
internal fault/error. Possible faults/errors are:
•
user stop
•
communications error
•
computation time overflow
•
hardware monitoring fault
The user stop can be initiated using the CFC- or the configured
software. If the T400 is inserted in an electronics box, generally, the
basic drive converter module signals a fault if the T400 is in the
user stop status.
If there is no user stop, the module must be accessed using the
CFC in the test mode or with Service-IBS V5, to precisely
determine the cause and to evaluate the internal fault fields.
If H1 flashes quickly (with 5 Hz), this indicates an initialization
error. The T400 program is either erroneous, or switch S1/7 is in
the ON setting.
If H1 goes into a steady light condition this indicates a system
error. The user program is not processed. The T400 is either
defective or has been incorrectly programmed.
The module must be accessed using the CFC in the test mode or
with the service-IBS V5 to precisely determine the cause, and to
evaluate the internal fault fields.
LEDs H2 and H3 indicate the coupling status to other modules. A
uniform flashing indicates an error-free coupling. The flash
frequency of H2 and H3 is determined by the configuring, i.e. the
sampling time of function block @DRIVE.
