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. An Output Pulse=005 secs in the above
example would cause OR-5 to turn On 5 secs/Off 5 secs during the lube cycle. 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).

In addition to the closed loop operation, two static inputs are monitored. A top stop is generated if either
input goes to a stop condition and further strokes are prevented until the fault is corrected.

Lube Type 005:

External Lubrication System

Input #33

Lube Fault 1

(stop if input = 0 volts)

Input #34

Lube Fault 2

(stop if input = 0 volts)

Input #35

Lube Fault 3

(stop if input = 0 volts)

Output #21 (OR-5)

Lube Fault

(opens if fault occurs)

This is a lubrication system that is performed external to the system 5000. If any lube fault input goes to
a stop condition, the press top stops and displays the specific input (i.e. Lube Fault 1). If the input remains
in a stop condition after the press stops, the lube system output OR-5 will turn off. This output will
remain off and further stroke initiation is prevented until all inputs return to the run state. The output is
intended to be used to turn off the main motor in the event of a lube system fault. The timers associated
with the lube system are not used and should be set to zero.

Lube Type 006:

Pulsed Lube without Flow Rate Sensor

Input #33

Low Lube Level

(stop if input = 0 volts)

Input #34

Lube Pressure Fault

(stop if input = 0 volts)

Input #35

Not-Used

Output #21 (OR-5)

Lube System Output

This is an open loop lubrication system where the system 5000 Lube System Output (OR-5) is used to
drive a Lube Pump. When power is first applied and the main motor is turned On, an internal timing
system is started. The lube system output OR-5 is turned On for the duration set by the "Flow Rate
(Power Up)" time (in seconds). After the cycle is complete the output can be programmed to remain on
an additional "Output On" time (in seconds) before turning off. The output then remains off for the
"Output Off" time (in minutes). Unlike type 004, the Off time is Not conditioned with the clutch/brake
signal and times as long as the main motor is turned On. When the "Output Off" time expires, the entire
cycle repeats. The lube system will "pause" its present timing function and turn OR-5 Off when the main
motor is turned Off, and resume timing when the motor is turned back On. The length of time that the
lube system is turned On can be set differently for a machine power up condition and the normal operating
condition. A flow rate time (power up) set to 000 secs causes no lubrication to take place when power
to the press is applied.
