Overview
PressCam 8 is a “control reliable” resolver based programmable
cam switch, time-based brake monitor, die protection system, multiple
counters, and much more in one package. The system contains two 16-bit computers that are configured to cross check
each other and the resolver. The dual computers are interfaced with a
full view 8" (203mm) diagonal LCD computer screen for viewing and
programming ease. This large operator screen (shown on the next page)
supplies operators and front line supervisors production data without
the need of cumbersome menu and program access codes.
All system faults generate
descriptive plain English error messages on the computer screen. This
provides floor personnel fast and reliable information related to the
machine stoppage. The system is also provided with special watchdogs that
turn off fault outputs should either computer become erratic. The software
and system customization in both computers can be upgraded in the field
using a PC computer with a standard serial port.
Programming PressCam 8 is so
easy that you do not need a keypad, keyboard, or cumbersome programming
techniques as required with competitive units.
Operator
Screen
A large 8" (203mm) diagonal
LCD computer screen is standard equipment on the PressCam 8. This single
component brings the intelligence of the dual computer system to the punch
press control panel. This in turn provides positive system status interaction
with the machine operator.
The screen brightness (contrast)
is also adjustable so it can be easily read even when installed in dark
areas.
Digital
Programming Knob
This innovative device replaces
keypads or keyboards for programming PressCam 8. The programming knob
works similar to a computer mouse. Simply turn the knob to the highlighted
field or program you desire then push. Your program is accessed with no
keystrokes. By turning the knob, the appropriate numbers or letters appear
on the highlighted screen to program the specific function you desire.
Push again, your programming is completed! Additionally, no information
can be programmed if it is not applicable to the specific function or
operation.
 Industrial Grade Brushless Resolver
Transducer
A heavy duty brushless resolver
transducer replaces the current mechanical rotary cam switch. This unit
was designed for hostile industrial environments such as press punch mechanical
shock and vibration, extreme temperature and humidity, oil, coolant and
lubrication mists. The TR-20 features excellent repeatability and gives
absolute shaft position feedback. High speed operation along with long
transducer cable runs (up to 600 feet/183m) give the TR-20 wide application
ranges. The resolver is a passive device which contains no sensitive electronics
and has superb noise immunity.
The resolver mounts easily
to an end of a crankshaft and can rotate CW or CCW. Simple connector ended
transducer cabling is supplied to connect the resolver to the PressCam
controller console. The PressCam’s microprocessor based control constantly
monitors the resolver position and displays both the angular position
of the shaft and speed of the machine (tachometer).
