10.3 Replacing the COTi Central Unit and Lifting Mechanics
NOTICE
Working on the COT insert without complete removal of this
For some tasks on the COT insert, it may be enough to just pull the COT insert slightly out
of the machine. In this case, follow the procedure for replacement but observe the following
instructions:
► Remove the screws fastening the central unit and the lifting mechanics.
► You don't usually need to disconnect the cable. However, if the cable is too short, un-
plug it.
► Slightly pull the COT insert out of the machine.
WARNING
Heavy machine parts
► Make sure that the COT insert does not fall out of the machine!
Overview
Fig.314: COTi parts
The COTi for SIPLACE TX machines is split into three
separate parts (units) which are mounted directly to the
machine frame.
These parts are as follows:
1. Lifting mechanics left
2. Lifting mechanics right
3. COTi central unit
The parts are directly fixed with eight screws to the
machine frame (four screws at the COTi central unit and
two screws on each of the lifting mechanics).
For the positions of the COTi in the machine see 10.2 "Installation Positions of COT Insert (Table
Positions)" [}234].

Removal of left and right lifting mechanics
NOTICE
Shown by example
The following procedure is shown by example of the left lifting mechanics. The procedure
for the right lifting mechanics the same. Relevant differences will be mentioned.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation. Observe the instructions in section 1.2 "Preparatory Work..." [}15].

► Flip the safety catch down.
► Remove the safety bolt, to access the connec-
tion.
CAUTION!
Pay attention to the position and number of
washers used.

Fig.319: Safety switch
► Repeat for the right lifting mechanics if neces-
sary.
The procedure for the right lifting mechanics is the
same, the only difference being that the safety
switch(1) must be removed.
► Remove the two fastening screws(2) of the
safety switch.
CAUTION!
Do not loose the sleeves.

Removing the COTi central unit
CAUTION
Heavy machine part!
The COT central unit is heavy. To lift it out, you will need to use the fit-up aid and a suitable
lifting device (hand-operated crane etc.).
