SSC-1500 Part Revolution Solid-State Control
SECTION 4—PROGRAMMING
TIMED SETTINGS
The SSC-1500 press control has a timed settings screen that is used to program the anti-tie-down, timed inch, and signal time-out settings.
ANTI-TIE-DOWN SETTING
The anti-tie-down setting is the amount of time within which all actuating means (palm buttons or foot switch[es]) must be concurrently depressed.
Once one of the actuating means is depressed, the timer starts. If the set time is reached before the other actuating means is depressed, the control
will not allow the press to begin a stroke. The range of 100 - 7000 ms allows enough time for single or multiple operator stations to depress all
actuating means. The typical setting for one operator is 250 ms, which is the factory default setting.
TIMED INCH SETTING
The timed inch setting is the amount of time for which the clutch will engage when in the
Inch
mode of operation. This prevents the operator
from having to depress and release the palm buttons in rapid succession to get small increments of slide movement. The dual solenoid valve is
deenergized when the set time is reached, even though the palm buttons may be held activated.
If timed inch is not required, the programmed setting should be at 0 ms, which will disable this feature. When timed inch is disabled, the normal
Inch
mode of operation will be active. In the normal
Inch
mode, setup or maintenance personnel can hold the palm buttons, allowing continuous
movement of the slide, or they can depress and release the palm buttons in rapid succession to allow only small increments of slide movement. If
the palm buttons are held depressed, the maximum travel of the crankshaft that the control will allow is approximately 220°.
SIGNAL TIME-OUT SETTING
The signal time-out setting is the amount of time within which a signal from an automatic feeding mechanism or other auxiliary equipment must be
received by the control in order to cycle the press. This applies only when the press control is in either the
Automatic Single Stroke
or
Continuous-
On-Demand
mode of operation. To turn the
Automatic Single Stroke
or
Continuous-On-Demand
mode of operation on, refer to the optional modes
section on pages 58 - 60.
The programmed time must be longer than the entire
Automatic Single Stroke
or
Continuous-On-Demand
sequence of operation. If the signal is
not received within the programmed amount of time, the press will not cycle. If the signal is received within the programmed amount of time, the
press will cycle, and the signal time-out setting will reset and start over.
Initially, the timer is started on the first stroke by pressing the prior-action button. The palm buttons must then be used to initiate the first stroke. After
the first stroke, the timer is started when the signal from an outside source is received. To stop the press once it is in the
Automatic Single Stroke
or
Continuous-On-Demand
mode of operation, press either the emergency-stop or top-stop palm button.
