Remakes
As you can see in Graph 1: Remakes by responsible party, errors
by the TKA Drawing Office result in the second highest number of
remakes.
Graph 1: Remakes by responsible party.
Compared to 2009-2010, the number of remakes assigned to the
TKA Drawing Office decreased from 131 to 113 in the last fiscal year.
This is a reduction of almost 14%. In this Bulletin we want to focus on
recent improvement measures implemented by the Drawing Office,
resulting in further reduction of remakes.
Measures for reducing remakes
The process of generating a drawing from measurement data supplied
by the FOs and resellers is manual. This means that factors like
skills, experience, and concentration have a significant impact on
the end result. Over the last 1.5 years, various measures have been
implemented to achieve a positive effect on these factors:
- increase in awareness and experience by discussing all
remakes assigned to the Drawing Office with the entire team
on a weekly basis;
- introduction of training sessions where experienced staff
conduct sessions with the rest of the team, resulting in
improved skill levels and uniform ways of working;
- renovation and expansion of office space to create a
comfortable environment in which staff can concentrate more
effectively.
Improvements have also been made to the drawing software. For
example, the input of certain parameters has been automated which
has eliminated the risk of manual input errors. Automated verification
of certain items of the configuration data has eliminated the risk of
items being forgotten.
More recently, an extensive check of the drawings produced was
introduced, which is carried out by experienced staff. The objective
was not only to eliminate errors, but also to give instant feedback and
thus enhance skill levels.
The results are quite impressive as you can see in graph 2. In this
graph, the bars show the development of remakes as a percentage of
the total production by quarter, and the trend line. The percentage of
remakes fell from over 0.9% to almost 0.4% in the final month of the
second quarter!

Through registering and analyzing data we aim to understand
which areas we need to improve in and monitor the results of the
measures taken. We count on your support to provide us with
accurate and detailed data and feedback so that together we can
improve our products and processes.
If you would like any further information regarding remakes, or
if you require specific data or reports to support your business,
please contact Bart Kruithof, Quality Engineer at

Power supply
1. Cut off the DC plug and discard.

2. The ribbed conductor is the positive pole.

3. Connect the power supply to the charging contacts on the
rail as usual. For this you can use the closed end crimp
connectors that are supplied with the charging contacts.

If you prefer, you can also use the Scotchlok connectors that are
provided as well. The advantage of the Scotchlok is that stripping
is not required.

Caution
When you first run the unit onto the lower charging contact (reset
point) make sure that ‘rSt’ appears in the display. Also, check
that ‘rSt’ does not appear on any of the other charging contacts.
Modify the wiring connections if necessary.

Levant OutdoorRemoval of the shrouding
To remove the shrouding from the drive in order to gain access
for maintenance, you must pull out the two pins („tree clips“)
that hold the shrouding in place.
Most people will reach for one or two screwdrivers to hook behind
the head of the pin. The problem with screwdrivers is that they
are sharp and can easily damage the shrouding. Therefore, it
is better to use an Eeprom puller as shown in the pictures (you
might already have one to pull the Eeproms from a Flow1).

GeneralCancelation costs
Due to the change in production process (production of rail parts
instead of orders), the time at which an order is canceled has
an impact on the costs involved. As the cancelation scenarios
explained in the Technical Bulletin of June (issue 130) caused
confusion, please find further explanations below.
Flow2
There are two ways to cancel an order:
1) Entering an order from the start through to ordering extra
racks
This is the moment from entering an order (status 100) until
the start of the planning process (status 501) at 12:00 CET
by the TKA Customer Support. Nothing has been ordered,
and as the order has not yet been planned, there are no
material costs involved. The cancelation costs in this scenario
can be found in the transfer price list.
In case of cancelations around this time, besides canceling
the order in DOP, please contact the Customer Support
department by phone.
2) Racks are ordered up to and including powder coating
As soon as the production planning process is started at
12:00 CET it can’t be stopped. This is because orders are
produced by railpart and not by order, so there is no way
to skip specific orders from the production sequence. Only
the rail parts are produced; the chair and drive will not be
manufactured. A discount of 50% applies to the rail related
transfer price to calculate the total calculation costs.
The rail related parts are marked (*) in the listing below:

Levant
For the Levant lifts there are two possible cancelation scenarios:
1) Orders without premium rail and orders with no produced
premium rail
In this situation all stock can be transferred back to the TKA
stock. The cancelation cost is a fixed fee.
2) Orders with a produced premium rail
In this case the production and material costs are invoiced
together with the fixed cancellation fee. Man hours and
material are also charged against a fixed fee.
The total of the cancelation costs for the premium rail is
therefore always the same fixed price.
