Save characteristics
3 characteristics can be saved.
Each characteristic consists of two charts (direction OPEN and direction CLOSE).
When saving, data is transferred from the buffer (RAM) to the read-only memory
(ROM).
Required user level: Specialist (4) or higher.

15.3.2. Position-time characteristic
Conditions
●
Actuator of the type range SA 07.2 – SA 16.2/SAR 07.2 – SAR 16.2
●
MWG position transmitter in actuator
Properties
During recording, the current position, for modulating actuators also the setpoint
position, within an adjustable time interval (between 1 second and 1 hour).
Application
By assessing the position-time characteristics, the control behaviour can be assessed
or insights on the use of the actuator can be gained.

Characteristics M0313
Position-time M0806
Each characteristic has a designation:
ACTUAL-POSITION = actual position
NOMINAL-POSITION = setpoint position (modulating actuators only)
Use push buttons Up ▲Down ▼ to change between characteristics.

– – – 50 % (position between OPEN = 100 % and CLOSED = 0 %)
The following further information is saved with the characteristic (can be requested
via push button Details).
●
Saving date: Time of last position measurement
●
Starting date: Time of first position measurement
●
Scaling: Y-axis (position)
Set resolution (time interval)
Actuator controls records 10,000 measured values. Set resolution of e.g. approx. 1
second (parameter Interval position-time = 1 [s] ) results in a recording time of 2.7
hours (10 000 seconds). Once this value has been exceeded, the former positions
will be overwritten (ring buffer)
Required user level: Specialist (4) or higher.
