Material unwinder
General
The material unwinder consists of the
unwinder (1) and the strain relief (2). The
strain relief has the purpose of compensating
the jolting material movements which can
occur if large speed increases or decreases
(braking) in the material feeding rate occur.
The unwinder itself is braked and adjustable
to various core diagonals.
Unwinder

Connections and electrics
Important remarks
¯The housing must only be opened by
authorised skilled personnel!
¯Before opening the housing, switch off
the device and disconnect the mains
plug. If this is not done, there is a
danger of an accident due to dangerous
contact voltages.
Mains connection
The connection of the device to the mains is
effected via a combination unit consisting of:
– Mains-apparatus connection, (1)
– Voltage-selection switch, (3)
– Fuse insertion, (3)
– Hum eliminator (4) and
– Mains switch (2).
The voltage-selection switch and fuse inser-
tion both form the drawer for the protection
and switching of the operating voltage of the
device.
¯The mains voltage and the voltage set
on the voltage-selection switch must be
the same.
PDetails on switching the mains voltage
can be found in the USER MANUAL,
section "Commissioning and operation".
The hum eliminator prevents interference
impulses from penetrating the device or
getting out of the device into the national grid
(electromagnetic compatibility).

Changing the serial interface to RS485 mode
The serial interface of the TTX 350 can be
operated alternatively in either RS232 or in
RS485/422 mode. This can be changed by
means of two jumpers on the mainboard. The
factory setting of the interface is RS232 mode.
To change modes, please proceed as follows:
PRegarding this point, see also the
section "Periphery set-up"
Printers with periphery set-up
1. Remove the peripheral board.
PRegarding this point, see the section
"Printed circuit boards".
2. Position the two jumpers (1, 2) as shown
in the diagrams on the right.
•Centre diagram: Setting for RS232.
•Diagram below: Setting for RS485/422

Factory setting
At the factory, all parameters are pre-set to a value dependent on the type
of device in question. This factory setting can be restored at any time using
the parameter OTHR/FACT.
PFor more details on the factory setting, see the topic “Info printouts and
parameters”.
Zeroing the operating data
In order to initialise the printer as a new device during the final stage of
production, all continuously stored operating data are set to zero. Thus, the
status of the service report (STA3) also corresponds with the delivery state
as a new device.
Zeroing of the operating data is performed as follows:
Zeroing 1. Reset printer using keys FEED+CUT(NEXT)+ON/OFF.
Display: Version number, then INIT blinks.
2. While INIT is blinking, press the ON/OFF key.
Display: CODE.
3. Press the following keys one after the other:
