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).

times
the
actuator
has
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.

23 ACCESSING DATA ShEET
Select change in the MENU and turn to OK to confirm.
Select data sheet in the CHANGE menu and turn
to OK to confirm.
valve tag number
Select valve tag number to read or write valve ID.
Use the blue selector to change the first character and turn to
OK to confirm.
Change remaining characters using the same method.
Turn to OK when all of the characters have been entered and
continue until the menu is displayed again.
actuator number: this is the actuator's serial number. This information
is entered at the factory and is only shown in the CHECK menu.
entry code: for entering or changing a password, see below:
"Creating or changing passwords".
characteristics: parameter settings for correct operation of the
actuator (see details next page).
The following data is only shown in the CHECK menu.
operating class: indicates whether the actuator is designed for
on/off operation, class III control or class II control functions. This
item can be used to activate an alarm if the number of starts
is excessive (excess. starts alarm).
The number is the counted over the previous 12-hour period.
Limits are as follows:
On / Off:
360 starts in previous 12 hours
Class III:
1,200 starts in previous 12 hours
Class II:
21,600 starts in previous 12 hours
This alarms never causes the actuator to stop operating.
manufacture date: gives date product shipped from factory software version: installed software
release
Characteristics menu details
motor : this data indicates whether the motor has a 3-phase, single phase or DC
power supply (data from manufacturer)
protection: waterproof or explosion-proof version. The explosion-proof version prevents overriding
the thermal relay in the degraded mode/commands menu.
locked motor/s: Indicates the time the motor left energised when immobilised before power cut off.
Default: 10 seconds (manufacturer's data)
reverse delay/ms: Indicates time actuator halted following change in direction of rotation.
Default: 200 ms (manufacturer's data).
ratio position system: indication of gear stepdown ratio between output shaft and position sensor
for displaying stroke in number of revolutions (or in degrees for fractions of a revolution) (manufactu-
rer's data).
To check settings without making
changes, select check instead
of change in the menu.
