Output #21 (OR-5) Lube System Output
This is a closed loop lubrication system where the Lube System Output (OR-5) is used to drive the Lube
Pump. It is intended to be used on machines that require occasional lubrication to crankshaft bearings or
slide gibs (i.e. portions of the press that move only when the clutch is engaged). When the main motor
is turned on, an internal timing system is started. The Lube Pump output is turned on until flow is
reported by the lube cycle limit switch making a complete cycle (low to high to low, or high to low to
high). When operating correctly, this input will cycle before the "Flow Rate" time expires and will
complete the lubrication cycle. After the cycle is complete the output can be programmed to remain On
a fixed time (Output On time in seconds) before turning off. The output then remains off for some
programmed time (Output Off time in minutes). The Off time is accumulated only while the clutch/brake
is energized. The entire cycle then repeats. If the lube cycle input fails to switch within the “Flow Rate”
time, a lube system fault is generated. The press top stops if this occurs while running, and further stroke
initiation is prevented until an operator presses the RESET ERROR softkey in the press control menu.
The operator's recognition of the condition resets the internal timer and the lube cycle will start again. The
length of time allowed for the flow rate sensor to activate can be set differently for a machine power up
condition “Flow Rate (Power Up)” and the normal operating condition “Flow Rate (Running)”. A “Flow
Rate (Power Up)” time set to 000 secs causes no lubrication to take place when power to the press is
applied. It should be understood that when operating correctly, the flow rate time for both power up and
normal running conditions does Not determine the length of time that the lube pump is On. The pump is
turned Off as soon as the lube cycle limit switch makes one complete cycle as described above.
This type lube system requires the parameters shown below (any other parameters are not used and should
be set to 000). The Figure below describes a typical example of a press with a motor driven lube pump
connected to OR-5 that requires lubrication every 10 minutes and by observation it is found that the lube
cycle limit switch normally makes a complete cycle in 20 secs but may take longer when power is first
applied. When power is first applied and the
main motor turned On, output OR-5 will turn
On to provide lubrication and input #35 will be
monitored. If this input cycles within 60 secs
the first lube cycle is complete and OR-5 will
turn Off. It will remain Off for 10 minutes of
continuous stroking. The output will then turn
On for the next lube cycle and input #35 is
again monitored, but this time with a
maximum limit of 30 secs. The normal lube cycle will be complete and the output turned Off when the
input cycles (20 secs). A “No Lube Flow” fault is generated if the input does not cycle within 30 secs for
this and all additional lube cycles. Note: If a parameter is changed, the new setting will Not be used until
the present timing portion of the lube cycle is complete. For example, if the press control is presently
timing the 10 min Off time shown above and a new setting of 001 min is entered, the new setting will Not
be used until the present 10 min interval is complete. The 1 min setting will be used for the next and all
future Off times. To “force” the new setting to be used immediately you can turn power to the control
Off and back On or change the Lube System Type to 000 and back to 004. This will reset the lube system.
In applications where the Lube System Output (OR-5) is controlling a solenoid driven pump it may be
