Commissioning/venting the system

See Figure 6
A requirement for commissioning is that the
MDR lubricant reservoir has been installed,
filled, and vented properly according to the
assembly instructions. The main lubricant line
between the lubricant reservoir (MDR) and
metering unit (MDU) must also be installed
and filled with oil.
See the assembly instructions:
Chapter 4.5 - Main lubricant line and
arrangement
Chapter 4.5.1 - Venting the main lubricant l
ine and the MDU
Chapter 4.3.4 - Initial filling and venting of the
MDR lubricant reservoir
• Connect connector plug (1) to MDU
metering unit (2).
• Loosen hexagon socket screws (4x)
(WAF 3) (3) from the lid (4).
Light guides for the LED display are con-
tained on the inner part of lid of the metering
unit. During disassembly/assembly, the lid
must therefore be carefully removed, put
aside safely, and later put back on precisely.
• Carefully lift the lid with hexagon socket
screws and put it aside.
• Switch on the machine/system using an
external PLC.
By default, the MDU is configured so that
the enable input expects a high signal to
enable the system, i.e., to start lubrication
operation.
If no external enable signal is available du-
ring commissioning, the system can be
started and stopped by switching DIP
switch 3.
The capillary lines must be connected to
the system but not to the lubrication
points.
6.3.1 Venting the system
See Figures 5 and 7
Next, vent the valves and fill the capillary lines.
o Filling the capillary lines simultaneously
vents the valves.
o The outlets can only be filled/vented
successively, i.e., at any time only one
outlet can be activated for this procedure.
o The filling procedure is activated by switch
position "F".
o If one outlet is in filling mode, all other
outlets pause regardless of the setting
selected on the SV switches.
o If the switches for multiple outlets are in
position "F", the filling procedure is
performed for the outlet with the smallest
number.
o The filling procedure is stopped by switching
the SV to position "0".
