USER INPUTS
Up to four programmable user inputs are available to monitor and diagnose common problems with auxiliary equipment on the machine. See the
USER INPUT programming section on pages 31 - 32 for the user input choices. Refer to the wiring schematics for information on wiring the inputs
to the proper terminals.
Note: If block valve monitoring is enabled, only three (3) user inputs will be available.
SPEED CHANGE—REQUIRES OPTIONS MODULE
An optional speed change limit switch can be connected to the speed change selector switch to facilitate HIGH, HIGH/LOW, or LOW speed on
machines with speed change solenoid valves. (See the schematic diagram supplied with the control for switch connection.) The speed change
limit switch can be either N.O. or N.C. and the speed change solenoid valve can be energized for slow or fast as required. (See the OPTIONS EDIT
programming on page 33.) The speed change logic will work with either a momentary or maintained limit switch.
AUTOMATIC SINGLE STROKE—REQUIRES OPTIONS MODULE
The automatic single stroke mode of operation is used when a continuous stroke operation is desired but the press is faster than the material
feeding equipment. When this mode of operation is ON, each press cycle can be initiated by the material or material feeding equipment. This mode
of operation requires a prior-action pushbutton station. To initiate automatic single stroke, set the Mode Selector to “Single” and enable “Automatic
Single Stroke” in the programming menu (see ASINGLE MODE programming on page 30). Press the prior-action push button and then both run
buttons concurrently (within five seconds). The press will make one stroke and then continue to run in automatic single stroke as long as an input
signal is received. The press will operate in the automatic single stroke mode of operation until a signal is given to stop, or when the automatic
single stroke timer runs out before an input signal is received (see ASINGLE TMR programming on page 31). The prior-action pushbutton and the
palm buttons must be reinitiated to restart the automatic single stroke mode of operation.
BLOCK VALVE MONITORING—REQUIRES OPTIONS MODULE
This valve is used to monitor the state of the hydraulic block valve. When enabled, there
must
be a switch on the valve wired into User Input #4.
Refer to the wiring diagrams supplied with the control for wiring connection. This block valve monitor option uses User Input #4, which leaves only
three (3) programmable User Inputs available. (See the OPTIONS EDIT programming on page 33.)
