3 Initial operation and handling
3.1 Adjustment guidelines
Please read the detailed description first and subsequently use these guidelines as a checklist for
adjustments.

Extract samples from as close as possible to the probe.

Select switch position 1 on the product selection switch and do not change the setting
from this position until the moisture is near the target moisture (e.g. 3% above)!

Start up the dryer for the trial run, extract reference samples continuously approx.
every half hour and enter the reading together with the switch position in the adjust-
ment protocol (Page 30).

As soon as the grain moisture has fallen to 3% above the target value (for continuous-
flow dryers when the start-up phase is finished), extraction of reference samples must
be stepped up to take place at 15 minute intervals.

When drying is finished, the correct setting on the product selection switch must be
determined from the last reference values (less than 3% above the target value).
3.2
Adjustments for initial operation
The TRIME
®
-GW can only be adjusted when installed in the plant as the location and the bulk density
of the grain have a significant influence on moisture measurement. Adjustment must be carried out
separately for every product. The term “adjustment” refers, in this case, to the correct setting of the
product selector-switch.
Moisture measurement is dependent on the following parameters:

Location (e.g. metallic objects within the field of measurement)

Bulk density of the grain

Type of grain (product)
As soon as one of these parameters changes, another adjustment must be chosen using the product
selector-switch. The setting only has to be adjusted during operation when the product changes be-
cause the influence of the location remains constant and the bulk density of a given product remains
more or less constant as well.
3.2.1 Adjustment for plants with several TRIME
®
-GW
When the plant is only equipped with one TRIME
®
-GW, adjustments are made for the installation-
related influences at the same time as those for the grain product. Exactly the same procedure can be
followed as described in the next sections (3 to 3.2.7).
In plants with several probes, it may also be necessary to correct the deviations between the TRIME
®
-
GWs themselves. This is good policy only when all the TRIME
®
-GWs are to give an absolute meas-
urement. If the installation-related constant deviation of

1-2% presents no problem, it is sufficient to
make an adjustment using the most important probe, e.g. at the discharge point.
As usually only one product selector-switch is installed for all TRIME
®
-GWs, its setting always simul-
taneously applies to all the TRIME
®
-GWs. To carry out the extended adjustment for all TRIME
®
-GWs,
three steps must be taken:
1. Firstly, the TRIME
®
-GW that is most important for the drying operation must be selected. The pro-
be at the discharge point, for example, is a potential candidate. Whichever one is chosen, it must
be possible to extract samples directly at the point where this probe is located.
