a.
Depending on the Controls interface, this may require wiring 24VDC directly to the motor, or it
may be possible to command the motor to run continuously by interfacing with the PLC. The
motor needs to be running continuously to set the oil flow rates.
5.
Slowly close the return valve until the pressure switch activates, then lock down the setting with the
set screw on the return valve.
a.
The pressure switch setpoint is nominally 290 PSI. Set the return valve to produce approximately
320 PSI on the pump pressure gauge so the pressure switch is sure to activate.
6.
Put the end of one of the two feed tubes in a container to catch any excess oil, then open the
corresponding metering valve slowly. Let the pump run until oil comes out (purging the tube of air).
7.
Measure the flow rate by filling a small container of known volume and timing how long it takes.
a.
Use a container that will take at least one full minute to fill at the specified flow rate, which for
most sorters will be in the range of 30-60 ml (1.0-2.0 fl oz).
b.
A container with accurate volumetric markings (e.g. a graduated cylinder) is preferred, but the
adjustment process can be carried out with any container of the correct size capable of holding
oil if the volume of the container is known accurately.
c.
Ensure the container is clean to avoid contaminating the oil. If the oil is contaminated with dirt
or debris, do not put it back in the oil reservoir.
8.
Adjust the metering valve to set the flow rate according to Table 7 in Appendix 2 for an initial flow
setting (adjust as needed during operation to provide adequate lubrication).
9.
Repeat the measuring and adjustment process in steps 7 and 8 until the measured flow rate is
within 10% of the specified value.
10.
Mark the valve setting and close the metering valve fully.
11.
Repeat steps 6 through 10 for the second oiler feed tube and metering valve.
12.
Remove 24VDC power from the oil pump. If any wiring was changed to force the pump to run
continuously, replace the original wiring at this time.
13.
Open both metering valves to their marked settings and lock them down with the set screws on
each valve.
14.
Reconnect the tubes to the oil brushes.
15.
With the sorter running at operating speed, use the manual button (depending on the electrical and
Controls interface) to run the oiler for one full chain revolution. Make sure the oiler pressure does
not drop below the setpoint of the pressure switch (290 PSI).
16.
Reference Table 6 in Appendix 2 for recommended oiler running intervals and duration. The system
PLC should be programmed to run oil cycles at the specified intervals and durations based on actual
sorter runtime.
17.
Stop the sorter and lock out the drive.
18.
Inspect the chain and make sure oil is flowing to both brushes.
