User Friendly
The Mark Series controller is user friendly and no software programming is necessary. Two, four-line liquid crystal displays and a membrane keypad for displaying and entering functions are standard features, and the Mark VII prompts the operator for all start-up parameters, which are entered through the keypad or through a directRS 232 interface with a personal computer, a programmable logic controller or a terminal. No software education or training is required. Significantly, these parameters can be altered during equipment operation.
Versatility and Reliability
The Mark VII has one integral and four proportional gain settings for precise control of the output parameter over the entire equipment operating range, as well as four acceleration and four deceleration rates, all programmable within existing operating ranges.
Versatility is another key feature of the Mark VII controller. It can be configured as a stand-alone installation or fit into a standard 19” rack.
Security
Three levels of access provide security to the more critical controller functions. A special four digit access code, one for each level of access, must be entered before the controller can be activated.
Benefits of the Mark VII Controller
- Simplified construction consisting of off the shelf modularized components. The microprocessor motherboard with soldered connections has been upgraded to a modularized assembly. All components are connected with hard wiring for ease of installation and replacement via screw connections.
- The Mark VII can replace any previous Mark Series Controller with no modification required. The Mark VII is housed in the same NEMA 4 enclosure as all previous models. All connected inputs and outputs are identical to all previous models.
- Simplified troubleshooting procedure to isolate any controller component malfunction in minutes. Modularized construction and screw type connections make component removal and replacement easy and fast.
- Keypad operation is simple, straight forward and very similar to that of its Mark VI predecessor.
- A maintenance and troubleshooting kit is available for purchase. The kit includes all instructions, tools and spare modules to permit the user to troubleshoot and repair the Mark VII on-site, and within one hour in most cases.
- The four line liquid crystal input command and output shaft controlled parameter displays replace the former LED type displays.
- The Mark VII controller has no e-prom memory chip. The controller is pre-programmed for all required controller logic. This program is non-volatile and requires no battery backup. The program settings do require battery backup. The battery is a typical coin type cell that exhibits long life, is common and readily available.
- The Mark VII controller has the capability to perform any and all task previously performed by any other Mark Series controller.
