The duration of the time interval is equal to the time set by the Flow Rate configuration parameter. There
are two flow rate configuration parameters. The Flow Rate (At Power Up) is the parameter that is used
for the first time interval after power is applied to the OmniLink control. All other time intervals are based
upon the Flow Rate (When Running) parameter.
If only one flow rate sensor is being used, it will be necessary to jump Input # 34 to Input # 35. The single
flow rate sensor can be connected to either Input # 34 or Input # 35.
The special firmware is required to run this lube type. The special firmware that contains lube type 007
does not contain lube type 003.
Section 6.1.12 Hydraulic Overload I/O
The inputs and outputs provided are intended to interface to an external hydraulic overload mechanism,
and the internal monitor can be configured by the factory for different types. The type selected alters the
function of the hydraulic overload inputs and outputs in the following manner:
Hydraulic Overload type 000: No Hydraulic Overload Monitored
Input #36 Not used
Input #37 Not used.
Output #18 (OR-2) Not used.
Output #19 (OR-3) Not used.
Hydraulic Overload type 001: Limit switch/Pressure switch
Input #36 Hydraulic Overload Limit Switch
Input #37 Hydraulic Overload Pressure Switch
Output #18 (OR-2) Hydraulic Overload Cylinder
Output #19 (OR-3) Hydraulic Overload Pump
Under normal operating conditions, both outputs are On and both inputs are in the run state (+24 volts).
If either input opens (0 volts) a hydraulic overload fault is generated, and both outputs turn Off. The press
stops immediately if this occurs while running and the input that caused the overload is displayed as the
reason for the stop. The operator must then reset by following the steps described below:
Step
1.
Acknowledge the overload by pressing the RESET ERROR softkey.
2. Switch to Inch Mode. The present running status will display “Run Only In Inch” and will prevent
stroke initiation until this is done.
3. If necessary, switch the main motor to Reverse to “back off” the load (if the press is equipped for
this).
4. Use the correct run buttons to Inch the press to the top of the stroke. The press control will
automatically stop the press inside the hydraulic overload reset area at the top of the stroke.
5. The press control will inhibit further stroking at the top of the stroke and automatically reset the
hydraulic overload system by first turning the Cylinder Output (OR-2) On. The present running
status will indicate the status of the limit switch until input #36 switches high.
6. The present running status will then indicate that fixed 20 second delay is performed before the
