PressCam 8 is a “control reliable” resolver-based programmable cam switch, time-based brake monitor, die protection system with 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.

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 providing 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.
This innovative device replaces keypads or keyboards for programming the 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.
The heavy duty brushless resolver transducer replaces the current mechanical rotary cam switch. This unit was designed for hostile industrial environments such as punch press mechanical shock and vibration, extreme temperature and humidity, oil, coolant and lubrication mists. The resolver transducer 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 resolver 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 clockwise or counter-clockwise. Simple connector ended transducer cabling is supplied to connect the resolver to the PressCam 8 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). 3/4” (19 mm) resolver shaft diameter.
Shown above is the actual screen size and information available to the press operator on the PressCam 8 Programming Screen. No longer is it necessary to scroll through various menus and programming techniques to view
data. The Programming Screen also provides an active “tool bar” for your press set‑up personnel to quickly access the specific function they so desire. As one can see, a tremendous amount of production data can be obtained by simply viewing this single operator screen.
System simplicity is a dominant feature of the PressCam 8. By viewing the above screen, information can be obtained for four different counters, reset all faults, adjustment for screen contrast, die protection information, programmable limit switch information, shaft angle displayed in degrees, stroke per minute (SPM), and brake monitoring information.
Additionally, system fault messages are displayed in the area above the brake monitor setpoint section when they occur.
The Die Protection Screen shown above is what your programmer will see when entering the die protection program. PressCam 8 provides sixteen different die protection sensor inputs that may be programmed for both cyclic and/or static function monitoring. Cyclic function monitoring requires that an input sensor signal occur within a certain programmed shaft angle on each press cycle (e.g., part eject, part transfer). Static monitoring is used for non‑cyclic events such as end of material or stock buckle monitoring. A fault output will occur if an input transition is not detected between the programmed limit set points (e.g., a part is to be ejected out of the die between 190º and 250º of the machine cycle). If the part is not detected within these parameters, a fault or stop signal is given to stop the machine.
To program, simply turn to “die‑sensor set‑up” and depress the programming knob. Now you are in the die protection program. Then put in the parameters in degrees when you would want to look for the part to eject
or transfer. From 190º to 250º is when the sensor will be looking for the part. That is all there is to programming
die protection. If a fault output occurs, simply view the screen and determine from what sensor the fault occurred.
The die protection program can be fine tuned while the machine is in motion along with related peripheral signals
such as feeds, lubrication, blowoffs, etc. This is an excellent method of increasing the machines efficiency.
Limit switch programming simplicity is a PressCam 8 feature. PressCam 8 crank angle position is generated by a heavy duty industrial resolver driven by the press crank shaft. PressCam 8 provides the user with eleven programmable limit switch outputs used to initiate various peripheral equipment. These outputs can be programmed to turn on and off up to three times per press cycle. The programmable limit switch outputs may be mechanical relay, solid state AC, or solid state DC. The solid state relays may be mixed on the same relay board. The Delay and Hold cycle feature provides control for lubrication systems, scrap choppers, etc. This provides you with signals when you need events to occur on a pre‑programmed intermittent (time) or multiple stroke basis. Limit switches 1 – 7 can be programmed to turn ON and OFF up to three times per press cycle. Limit switches 8 – 11 can be programmed to turn ON and OFF up to two times per press cycle or may be programmed to turn ON based on angle and OFF based on time. The timed outputs can be programmed from .001 to 10 seconds. Furthermore, these switches may be used with the Delay and Hold cycle feature which provides control for items that need not be initiated on every press cycle but a programmed number of press cycles. Or they can be held ON for a pre-programmed number of press cycles. A minimum and maximum speed limit setting can be used to monitor optimum running speed versus actual. A deviation outside the programmed parameters will initiate a stop signal. The system includes a true motion detection system that monitors the press cycle. If you tell the press cycle and it fails to move within the pre-programmed time (.001 to 4 seconds), a fault signal is issued. On the opposite side, if the press starts to cycle without initiation, a fault signal is issued to electrically disconnect all signals. The clutch/brake timing signals can also be password-protected from inadvertent tampering by unauthorized personnel.
The TLM I/0 load module is designed for critical force measurement applications where accuracy, extreme stability,
and dependable noise rejection is essential. The module is a load measurement device without a display or alarms.
The TLM is used as an input device to the PressCam 8 providing display and alarm control functions. The TLM has high sensitivity levels that work well in an electrically “noisy” environment. It has two amplifier gain ranges (span ranges). Therefore, it can accept either weak or strong signals from the load sensor.
