energizes a motor driven lube pump for 10 seconds every 1000 strokes. When power is first applied and
the auxiliary Lubes are enabled (input #57 switches high) the lube has been programmed Not to generate
an initial lube cycle and instead proceeds to count 1000 strokes with output OR-14 Off. The output will
then turn On for 10 seconds to complete one lubrication cycle. This 1000 strokes Off and 10 secs On lube
period will continue as long as the enable signal is high. 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 counting 1000 strokes shown above and a new setting of 20 is entered, the new
setting will Not be used until the present interval is complete. The 20 strokes setting will be used for the
next and all future Off cycles. To “force” the new setting to be used immediately you can turn power to
the control Off and back On or change the Aux. Lube 2 Type to 000 and back to 001. This will reset the
lube system.
In applications where the Aux. Lube Output (OR-13/14) is controlling a solenoid driven pump it may be
necessary to pulse this output during the lubrication cycle. An additional "Output Pulse" timer sets the
rate at which the output turns On and Off. If “Output Pulse”=001 in the example above, when the lube
cycle starts OR-14 would turn On for 1 second and Off for 1 second during the 10 second lube interval.
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).
Aux. Lube Type 002: Pulsed Output with Flow Rate Feedback.
Input #51/52 Pulsing Flow Rate Sensor
Input #57 Aux Lube Enable
Output #29/#30 (OR-13/14) Lube Pump
This lubrication system waits for the Aux Lube Enable input to be switched to +24 volts before beginning
the designated timing. The lube pump output will be turned Off if the enable signal is removed. When
power is applied to the press and the enable input is turned On, the auxiliary lube pump is turned On and
the "Lube Fault Input" is monitored for flow. The output remains On until this input makes one complete
cycle (low to high to low) or (high to low to high), at which time the output is turned Off and the
lubrication pulse is complete. If the flow rate sensor fails to make a cycle in the time specified as "Flow
Rate (Power Up)" (in secs) the output is turned Off and the error message "Aux. Lube Fault" is displayed.
Further strokes are prevented until an operator presses the RESET ERROR softkey, at which time the
lubrication pulse will again be attempted. If the flow rate time at power up has been programmed for 000
Sec, no lubrication pulse is given. After the lube pulse is successfully completed, the pump output is
turned Off until the press makes the specified "Number of Strokes Off". The pump output is then turned
On and the flow rate sensor monitored for the time specified as "Flow Rate (Running)" (in secs). Failure
of the flow rate sensor to make a complete cycle generates the same fault as described above. This
lubrication cycle repeats as long as the enable signal is turned On.
The Figure below describes a typical example of
auxiliary lube system #1 being used to lubricate a
cushion. Type 002 is used because the cushion has
a flow rate sensor that normally makes a complete
cycle in 7 seconds. When power is first applied and
the auxiliary Lubes are enabled (input #57 switches
