22 VIEWING ACTUATOR HISTORY
22.1
ACTIVITY
Select change in the MENU and turn to OK to confirm.
Select activity in the CHANGE menu and turn to OK to
confirm.
Select number of starts or running time to view total figures
since the actuator was manufactured. The system also includes
a separate counter which can be reset by the user.
Select total to view total number of starts.
To reset the partial counter, select reset partial and then
choose yes or no (this option is only displayed when the user is
in the change menu).
starts / 12 hour: this data relates to the num-
ber of times the actuator has started during
the previous 12 hours and tells the user about recent service.
This is particularly useful when trying to establish whether the
actuator has been subjected to excessive use when performing modulating actions.
handwheel action: indicates whether the handwheel has been used since the last time a motorised
movement was made. (changes are only registered if they exceed 10% of travel).
22.2 ALARMS
Alarms are used to pinpoint the source of malfunctions. They are not permanent and are deactivated
when the fault is cleared. A blinking black square is shownon the screen to indicate that an alarm
has been activated. To read alarms: Select check in the MENU and turn to OK to confirm .
Select alarms in the menu CHECK menu and turn to OK to confirm.
Use the right-hand selector to scroll through any active alarms.
To check settings without making
changes, select check instead
of change in the menu.
