7.4 Recording the torque curves
This chapter does not apply to 2SG5… .
Preventive valve monitoring is possible by comparing up to three torque reference curves recorded
at different times which the actuator is in operation.
■
Prerequisite for the recording of the torque curves is a valid end position setting.
■
The represented values may differ from the actual torque, especially in the end positions and for
speed variations during operation.
■
A comparison of the recorded torque reference curves is only possible if the actuator settings
and the valve conditions are identical.
The recording of the torque curves can be performed:
■
directly at the actuator via
– push buttons. This method is described in the following,
– the COM-SIPOS computer parameterization program (actuator must be set to“ Local ready“);
■
from „Remote“ via Profi bus DP-V1 (actuator must be set to „remote ready“).
The travel is scanned in 1 % steps. Each curve can be overwritten.
For linear and part-turn actuators, the displayed curve is proportional to the actual force curve of
the linear actuator or the torque curve of the part-turn actuator.
When recording the torque reference curves, the actuator operates the valve at least twice over
the whole travel.
Bedienungshinweise
■
The blinking indication can be modifi ed with the or button.
■
The selected indication is accepted by pressing the “ENTER” button; the next setting is dis-
played.
■
To cancel use the Local/Remote button, during curve recording the STOP button.
■
Faults during recording (blockage of the travel, cancelation by the operator, failure of the power
supply etc.) are indicated by „error while rec.“. Acknowledge this message with ENTER. The
actuator changes to the „rec.torque graph“ initial state. The canceled recording or curve is only
stored for a fault diagnosis in the RAM until the next power failure (mains and auxiliary voltage).
Therefore, COM-SIPOS can read the curve up to the cancelation.
Operation sequence
1. Call up the main menu in the „locPar“ state, select
„commissioning“ menu and enter code 9044.
