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 60 minutes if the main motor is running and does not
have a flow rate sensor. When power is first
applied and the main motor turned On, output
OR-5 will turn On for 30 secs to provide
lubrication. OR-5 will turn Off and remain Off
for 60 minutes (timed only while the motor is
On). The output will then turn On for 10 secs to
complete the next lube cycle. This 60 min Off
and 10 secs On lube period will continue as long
as the main motor is running. 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 60 min Off time shown above and a new setting of 001 min is entered, the new setting
will Not be used until the present 60 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 006. This will reset the lube
system.
In applications where the Lube System Output (OR-5) is controlling a solenoid driven pump it may be
necessary to pulse this output during the lubrication cycle. The "Output Pulse" timer sets the rate at which
the output turns on and off. When the lube cycle starts, OR-5 is turned on for the duration set by the
output pulse time and is then turned off for the same period. The output continues with this "50% duty
cycle" operation until the lube cycle is complete as described above. An output pulse time set to 000 secs
or a time set greater than the flow rate time will result in the lube output remaining on constantly during
the lube cycle (as would typically be used when controlling a motor driven pump).
As indicated, this lube system does not monitor the lube flow. Two static inputs are monitored, and a top
stop is generated if either input goes to a stop condition. Further strokes are prevented until the condition
is corrected.
Lube Type 007: Recirculating Oil with Two Flow Rate Sensors (Special Firmware Required)
Input # 33 Low Lube Level/Press(stop if input=0 volts)
Input # 34 Pulsing Flow Rate Sensor # 1
Input # 35 Pulsing Flow Rate Sensor # 2
Output #21(OR-5) Lube Fault (opens if fault occurs)
This is an internally "timed" and "counted" lubrication system. This lube monitor is designed to count the
number of cycles of two pulsing flow rate sensors during a time interval. If the number of cycles of each
sensor during a time interval equals or exceeds the number assigned to the Min # Pulses configuration
parameter, the lube system is considered to be operating properly. If the number of cycles of either sensor
during the time interval is less than the number assigned to the Min # of Pulses configuration parameter,
a lube system fault is generated and the press will top stop. After slide motion has ceased, the lube output
(OR-5) will be turned off. The stop condition will remain until the number of pulses for each sensor
during a time interval equals or exceeds the number assigned to the Min # Pulses configuration parameter.
