PressCam 8 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
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.
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
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).
