Self Tests SMPS-MC
Relays K3/K4 are deactivated during all self tests.
No. Test
Description
Reaction SMPS-MC
Reaction
-
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
