4.
Install the external measuring device so that it can measure the displacement of the
positioner. If the measuring device shows a value other than zero, note the offset and
subtract this from the values read in the following measurements.
5.
Connect the power cord on the wide-range-input power supply to the power socket.
The E-625 is ready for operation when the green
Power
LED comes on.
6.
Increase the input voltage on the
ANALOG IN/WTT
SMB socket in increments of 1 volt
from 0 V up to the value where the upper travel range limit for the positioner is reached
approximately.
7.
Reduce the input voltage on the
ANALOG IN/WTT
SMB socket to 0 V.
8.
Read the sensor signal on the
SENSOR MONITOR
SMB socket using the voltmeter.
9.
If necessary, perform (p. 27) a zero-point adjustment of the sensor.
10.
Increase the input voltage on the
ANALOG IN/WTT
SMB socket slowly up to the value
where the external measuring device shows the nominal displacement of the positioner
(upper travel range limit).
11.
Adjust the R143 (p. 37) sensor gain potentiometer on the main board with the trimmer
adjustment tool until the until the voltage on the
SENSOR MONITOR
SMB socket is
10 V.
12.
If necessary, repeat the last steps until stable values are displayed on the measuring
devices.
Do you want to use your system in closed-loop operation?
If so: For the highest positioning accuracy in closed-loop operation, adjust (p. 51) the
static gain factor.
If not: Disconnect the E-625 from the power source by removing the power cord of the
wide-range-input power supply from the power socket and close the E-625.
Adjusting the Sensor Range in Computer-Controlled Mode (only E-625.CR)
1.
Select computer-controlled mode and open-loop operation (servo mode OFF) using the
Settings
DIP switch block:
−
1: OFF (up)
−
2: ON (down)
−
3: OFF (up)
−
4: ON (down)
2.
Optional: Connect the voltmeter to the
SENSOR MONITOR
SMB socket using the
adapter cable.
