4.8.2.30.1 Self Tests SMPS-MC
Relays K3/K4 are deactivated during all self tests.
No. Test Description Reaction SMPS-MC Reaction Dialog+
-
Flash memory Microcontroller of SMPS-
MC checks the flash
memory
Condition:
• Machine connected to mains
Response:
• Power-On reset + CRC
Condition:
• Mains switch ON
Response:
• Watchdog timer reset + CRC
Error in flash:
• Switch-on not possible, quick flashing of the
operating status LED H900 (5 .. 10 Hz)
110
Service mode
(/DIR_ON)
Microcontroller of SMPS-
MC checks the operating
mode
Service jumper X101 connected
• TSM mode (alarms deactivated)
Service jumper X101 not connected
• Therapy mode (alarms activated)
if /DIR_ON = 0 (service jumper
X101 connected):
• Therapy is rejected
• Error message is generated
111
Buzzer test
(the buzzer is
tested via LLS in
# 115)
Microcontroller of the
SMPS-MC checks the
function of the buzzer
(without drive/activation
from LLS)
112
Battery test
(is performed
only if option is
present)
Check whether battery is
connected and if
connected, check whether
battery is charged
sufficiently
OK:
• Battery present and charged sufficiently
not OK:
• Battery not present or not charged sufficiently
if not OK:
• Warning is generated
• Therapy still possible
113
EEPROM Microcontroller of the
SMPS-MC checks the
EEPROM memory
(EEPROM currently not
used)
114
Hardware
watchdog WD
In TSM service program
only
A simulated microcontroller
failure tests the function of
the hardware watchdog
(the trigger signals for the
hardware WD are switched
off)
Condition:
• Trigger HW-WD
Response:
• Buzzer and staff call ON
• +24 VGX OFF
• Heater OFF
Only a reset of the microcontroller (enable voltage)
deactivates the alarm (mains connector must be
disconnected from the mains > 30 s)
If switch-off time < 30 s
Mains plug was connected again without waiting more
than 30 s. LED H900 on SMPS-MC continues to flash
- Remove fuse on battery rack -- LED H900 goes
out.
- Insert again the fuse.
115
Buzzer test via
LLS
Microcontroller of SMPS-
MC checks the function of
the buzzer
The +24 VGB and +24 VGD are always switched off
during this test (a communication between LLS and
SMPS-MC is not possible without this switch-off)
• LLC informs LLS via DIABUS
• LLC sends #115 to SMPS-MC
• LLS must activate AKAL-S within 5 s
OK:
• Buzzer OK.
not OK:
• Buzzer not OK.
if not OK:
• Warning is generated
• Therapy still possible
