5 Set/Test
In the power supply unit, there is a safety element, which 
needs refreshing at least every 1.5 seconds. If the main 
CPUs software will not refresh, safety element gives 
reset to main CPU. In normal operation the main CPUs 
software refreshes safety element every 0.2 seconds.
The purpose of the safety element is to restart the 
monitor if there is a serious malfunction. This feature is 
useful in two cases: when the main CPUs software is 
not able to control the monitor, and when the software 
controls the monitor but detects a serious malfunction.
 Watchdog tests ensure the proper functionality of the 
safety elements various sections.Watchdog test 
ensures directly that the watchdog of the power unit 
functions properly. Choosing this test prevents safety 
element from refreshing and shows running seconds 
with an accuracy of 0.1 seconds.
The test should have the following result when the safety 
element is working properly: The monitor will restart after 
1.5 seconds from the start of the test. In malfunction: >20 s is displayed, and the test will interrupt. In this case, the
fault is in the safety element of the power unit.
WD by Overload test ensures the functionality of a feature, where the software controls the monitor, but detects an 
overload situation in the main CPU.
The test should have the following result when the feature is working properly: The monitor will restart after 15 seconds
from the start of the test.
WD by UPI test ensures the functionality of a feature, where the software controls the monitor, but detects 
amalfunction at  the UPI section. The test will prevent the UPI processor from functioning during the test.
Immediately after the test starts the plotting stops. The test should have the following result when the feature is 
working properly: The monitor will restart the UPI section without any visual effects.
WD by GSP ensures the functionality of a feature, where the software controls the monitor, but detects a malfunction
 
at the GSP section. The test will prevent GSP processor from functioning during the test.
The test should have the following result when the feature is working properly:  The monitor will restart the GSP section
without any visual effects.
Factory Reset restore factory default settings and clear data memories. Factory reset should be run if monitor 
software is replaced or if the SRAM/Timekeeper IC, or its battery is replaced.

6 Service Log
Error, event, alarm and maintenance data is stored in Service Log.
The service log contains information about the occurred monitor errors, events and alarms since the last factory reset 
or service log reset. The service log is saved in the EEPROM memory of the main CPU board. The user can also store 
different maintenance events in the maintenance log.
Maintenance menu is for setting and viewing the 
maintenance information of the monitor.
Error History is for selecting the error history view onto 
the right side of the menu.
Event History is for selecting the event history view onto 
the right side of the menu.
Alarm History is for selecting the alarm history view onto 
the right side of the menu.
Scroll Last Er (Ev) is for scrolling the error / event / 
alarm information on the right side of the menu.
Scroll Counters is for scrolling the error / event / alarm 
counters on the right side of the menu.
Record Data is for recording the service log information 
onto the recorder.
Reset Log is for clearing up the content of the service 
log. This function should be run after a performed 
maintenance. In Error/Event history view, the Reset Log 
command clears up both the error and the event log. In the Alarm History view, the Reset Log command resets only 
the alarm history log.

6.1 Maintenance
6.1.1 Planned Maintenance
The Maintenance History Log gives the user a possibility to store the maintenance history of the monitor. The user can 
store different planned maintenance (PM) events, repairs and upgrades in the maintenance history log.
Running hours: shows how many hours the monitor has 
been on. User cannot reset this value.
since This date and time is set at the factory and it 
shows the manufacturing date and time. User cannot 
reset this date and time.
since last 1 year PM: shows the running hours since 
the last 1 year PM storing.
Last events: The section shows the last maintenance 
events and the time of their occurrence. 
Event counters: The section contains counters for each 
different maintenance events. The time of occurrence of 
the last event is shown beside each counter.
1 Year PM gives you the possibility to store a 1 year PM 
event in the maintenance history log.
Other PM gives you the possibility to store another PM 
event in the maintenance history log.
Notify on PM This feature is for future purposes.

6.1.2 Repair
6.1.3 Upgrade
The repair menu gives the user a possibility to store re-
pair events in the maintenance history log. The different
repairs that can be saved are: Display, Power Supply,
Recorder, Frame (e.g. board in the frame), Parame-
ters (e.g. a board in the parameter module) or Other (a
miscellaneous repair not specified by previous op-
tions).
The upgrade menu gives the user a possibility to store
the upgrades in the maintenance history log.

6.2 Error History
6.3 Event History
Last Errors: The section shows the last monitor errors 
and the time of their occurence.
Error counters: The section contains counters for each 
different (detected) monitor error. The time of 
occurrence of the last error is shown beside each 
counter.
Last log reset: The date and time of the last Error/Event 
log reset.
Possible errors:
Fast cold start indicates the number of erroneous cold 
starts with power off time less than 20 seconds. The 
reason can be either a failing lead acid battery or a 
software problem that was solved by the hardware 
watchdog circuitry located in the monitor’s power supply 
unit.
GSP watch-dog timeout indicates an erroneous restart 
controlled by the main CPU board and caused by the 
display controller board. The restart is listed as a fast cold start.
UPI watch-dog timeout indicates an erroneous restart controlled by the main CPU board and caused by the UPI 
section. The restart is listed as a fast cold start.
Last events: The section shows the last events and the 
time of their occurrence.
Event counters: The section contains counters for 
each different (detected) event. The time of occurrence 
of the last event is shown beside each counter.
Last log reset: The date and time of the last 
Error/Event log reset.
Possible events:
Cold start is a start-up with power off time more than 
15 minutes. The trend memory is cleared and 
monitoring starts with the user default settings.
Warm start is a start-up with power off time less than 
15 minutes. The trend information and possible 
temporary settings are still available.
