5. Start-Up/Operation
Introduction
After the actuator is completely installed, wired, and the preliminary adjustments made, it is advisable to
check the operation of the actuator and controlled device before placing it in service. In other words,
operate the controlled device and check its direction of travel in response to an increase of the input signal
and make sure it is correct for the process. Actuators having the optional auto-manual switch must have the
knob set in the AUTO position.
This section provides a checklist that can be used to do a walk-through with the actuator before it is
actually used for control. Other features which may be helpful in understanding actuator operation are also
provided.
Power Up Diagnostics
When power is applied to the actuator, the actuator electronics performs a diagnostic routine on various
device components. These tests include a:
•
RAM diagnostic (RAMTST),
•
Check of the electrically eraseable PROM (SEETST),
•
Verification that valid parameter values are in the actuator configuration (CFGTST),
•
Verification of valid calibration values (CALTST)
•
Test of the local display and LED indicators (all display segments and LED indicators light
simultaneously).
The local display shows the status of the diagnostics as they are completed during power up. TEST DONE
is shown on the display when diagnostics are complete and actuator should be in AUTO mode. See Table
18 for more information on the power up diagnostics.
Operations Checklist
To make sure that the actuator is properly installed and set up for your particular application, you should
check and verify the following:
•
Verify that the configuration is correct for your application by stepping through all set up groups and
checking the setting of all set up parameters.
•
Verify operation of end-of-travel limit switches.
•
Verify operation of auxiliary switches or relay function (if installed).
•
Check operation of AUTO - MANUAL DRIVE switch (if present), by setting the knob to the CW and
CCW - MANUAL positions. The output shaft should rotate in the direction indicated by the knob. The
LED indicator on the local display should indicate the actuator is in manual mode by the LED blinking
at approximately a 1 second rate.
