Adjusting The Position Of The Display Unit; Replacing The Sensor Blade - Valmet SMART-PULP Operating And Installation Instructions

SMART-PULP
TRIM-F Calibration of shear force measurement
Select the TRIM-F function from the DIAGNOST
menu. Then select 1. WEIGHT from the submenu.
The displayed value is close to 0 g, because no
weight is attached to the sensor blade and the
blade's own weight has been eliminated. Allow the
reading to become stable. Then use the arrow keys
to adjust the displayed value to zero and press
[ENTER] to accept the value.
If you are just recalibrating the zero and do not want
to check sensitivity, select and confirm the SAVE
command and then the USE FRST subcommand. If
you also want to check and, when necessary,
recalibrate the sensitivity, attach a 1 to 3 kg weight
to the sensor blade after accepting and adjusting to
zero the unweighted 1. WEIGHT command. Then
select and confirm the 2. WEIGHT command. The
weight measured by the transmitter is now
displayed. Allow the reading to become stable, and
then use the arrow keys to adjust for the correct
reading (i.e. the same as the applied weight). Accept
this value and then accept SAVE and USE BOTH.
NOTE! Stable reading before usng the arrow keys.
In both cases SMART-PULP finally asks SAVE
OK?. Press [ENTER] if you want to save the results.
If password is in use (not 000), the prompt PASS=
will replace SAVE OK? Use the arrow keys to enter
the correct password and then press [ENTER].

TRIM-MA Calibration of current output
Select the TRIM-MA function from the DIAGNOST
menu. The transmitter will then give out a constant
current. Use the arrow keys to correct the displayed
reading in accordance with the actual measured
current, then press [ENTER] to confirm the reading.
Repeat the procedure for two other points. SMART-
PULP now knows the actual current corresponding
to its output at three different points.
4.4 Adjusting the position of the
display unit
Remove the junction box's cover by turning it
counterclockwise. Then turn the display unit
counterclockwise and pull it out. Fold the flat cable
to suit the display unit's new position. Replace the
display unit and lock it in the new position. Check
the cover's gasket, then replace the cover.

Replacing the sensor blade

Procedure:
• The sensor blade's retaining nut is secured with
Loctite. The nut can be unscrewed without heating.
• First unscrew the nut, and then detach the sensor
from its taper joint with an extracting tool.
