9 Maintenance and Servicing of the FCU
The FCU is maintenance free, except for the filter. The filter clogging is monitored by a
clogging indicator (2 bar). If the filter is clogged, a warning message shows up in the LC-
display.
Other useable items are:
•
Printer paper
•
Printer Ink ribbon
9.1 Filter Element Exchange:
When clogging of the filter element results in a differential pressure of 2 bar, the integrated
clogging indicator gives the signal for outputting a message on the FCU’s display. This
presupposes that the flow control valve is not closed, meaning a flow is shown in the
display. In addition, the inlet pressure has to be correspondingly high, i.e. at least 1 bar.
When the inlet pressure is insufficient, the flow rate becomes increasingly smaller, even
when the flow control valve has been opened completely.
In these cases the element has to be changed.
Before changing the element, the Fluid Control Unit is to be isolated from the system. Undo
the contamination retainer (filter bowl) sealing screw at the rear of the unit using a size 12
Allen screw wrench.
Note:
Collect any residual oil in the housing using a suitable container. Pull the filter element out
of the housing by the strap, then insert a new filter element, model: 0060 D 005 BN 3 HC,
article no.: 1260 891. Lubricate the O ring on the filter element somewhat and insert it by
turning it at the same time. Then check the O ring at the sealing screw to make sure that it
is intact, slightly lubricate it, reinsert the sealing screw, and tighten it until it is hand tight.
9.2 Changing the ink ribbon cartridge
a) Lift printer cover and fold back fully
b) On the right side of the ribbon cartridge, push where marked "Push" until the cartridge is
released.
c) Remove old ribbon cartridge.
d) When fitting the new ribbon cartridge, the "Push" label must be on the top of the right.
Feed paper strip through the ribbon cartridge (between ribbon and plastic cartridge).
e) Place the left side (ribbon drive) of the ribbon cartridge in first, then push where marked
"Push" on the right hand side until the ribbon cartridge clicks in.
f) Re-align paper and close printer cover. Approximately 0,5 cm of paper should emerge
from the cover.
