CONF600 PLUS – User’s Manual
17.4
Current Output
The current output can be 4-20 mA (live zero) or 0-20 mA (dead zero). Selection is made in the
blocks 009 to 012.
Connect a current indicator (mA) to the output to be calibrated and select the output to be adjusted
on the front panel. The program used in the controller has the current output 1 (BLK009) driven by
the A/M station of Loop 1. It is possible to adjust the current output with the controller in Loop 1 and
in Manual mode.
a) Select the option Current Output (0-20 mA or 4-20 mA) in the Calibration dialog box.
b) A dialog box will open asking the user if the default configuration is to be opened. Click Ok to
open this configuration or Cancel to start a new calibration.
c) Click the output cells to apply the default values.
d) Click the Download button.
e) At the CD600 Plus front panel, select the outputs using the <LP> key.
f) Set the output values to 0% using the <∇> key at the front panel and verify the reading at the
current indicator (that should be connected to the corresponding output at the CD600 Plus
terminal). If the value read is not 0, or 4 mA according to the option selected, type the new value
at the output field in the Calibration dialog box:
i. Double-click the value field to be edited, corresponding to 0%.
ii. Type the value read from the current indicator.
iii. Press Enter to confirm the new value.
g) Set the output values to 100% using the <Δ> key at the front panel and verify the reading at the
current indicator. If the value read is not 20mA, type the new value at the output field in the
Calibration dialog box:
i. Double-click the value field to be edited, corresponding to 100%.
ii. Type the value read from the current indicator.
iii. Press Enter to confirm the new value.
h) After editing the values, click the button Download at the Calibration dialog box to download the
new values to the device. The Download message box will appear to indicate the calibration was
downloaded with success.
Voltage Output
The voltage output is calibrated like the current output. The only difference is that a voltage meter
will be connected to the output instead of a current meter.
a) Select the option Voltage Output (0-5 V or 1-5 V) in the Calibration dialog box.
b) A dialog box will open asking the user if the default configuration is to be opened. Click Ok to
open this configuration or Cancel to start a new calibration.
c) Click the output cells to apply the default values.
d) Click the Download button.
e) At the CD600 Plus front panel, select the outputs using the <LP> key.
f)
g) Set the output values to 0% using the <∇> key at the front panel and verify the reading at the
voltage meter (that should be connected to the corresponding output at the CD600 Plus
terminal). If the value read is not 0V, or 1V according to the option selected, type the new
value at the output field in the Calibration dialog box:
i. Double-click the value field to be edited, corresponding to 0%.
ii. Type the value read from the voltage meter.
iii. Press Enter to confirm the new value.
h) Set the output values to 100% using the <Δ> key at the front panel and verify the reading at the
voltage meter. If the value read is not 5V, type the new value at the output field in the
Calibration dialog box:
i. Double-click the value field to be edited, corresponding to 100%.
ii. Type the value read from the voltage meter.
iii. Press Enter to confirm the new value.
i) After editing the values, click the button Download at the Calibration dialog box to download the
new values to the device. The Download message box will appear to indicate the calibration
was downloaded with success.
