PRESS CONTROLS
MECHANICAL POWER PRESS CONTROL SYSTEMS
Each mechanical power press must be looked at as an individual system. This system consists of, but is not limited to, the frame, all mechanical parts, clutch and brake assemblies, electrical or electronic systems, hydraulic systems, pneumatic systems, tooling or dies (present and future), tool or die setup, safeguarding, material handling, maintenance requirements, size or configuration of workpiece, and most importantly, production requirements.
​
CONTROLS
Controls are furnished according to the type of press: full revolution or part revolution. Please see later pages detailing these requirements for further explanation.
​
PART-REVOLUTION CONTROL SYSTEMS
A part-revolution control system consists of:
-
A control box
-
Individual components
-
OR Component packages
​
We offer a variety of control boxes that can be furnished to meet your specific requirements. The SSC-1500 solid-state control box version is available as follows:
1. Standard clutch/brake control
2. Custom clutch/brake control which includes a fused disconnect switch and magnetic motor starter
3. Special clutch/brake control
4. Remote operator style
​
SELECTING A CONTROL SYSTEM
​
To order a complete control system which includes control reliability and brake monitoring, determine which style control box is required. A standard control box includes the clutch/brake control and transformer. The clutch/brake control can also be furnished in a plain-door enclosure, as a subpanel, or as a module kit. The plain-door control requires a remote operator station. Subpanels and module kits are furnished without the enclosure; module kits include the primary internal components of the control only. Subpanels and module kits must be installed into an existing enclosure by qualified personnel. The subpanel or module kit also requires a remote operator station or a keypad/display kit. A custom control box includes a main power disconnect switch and magnetic motor starter in the same enclosure as the clutch/brake control. A reversing ram-adjust motor starter may also be included. Special control boxes can include either a standard or custom clutch/ brake control that requires modification for any special requirements. This can be an interface of auxiliary equipment, such as a lube system, a light curtain interface for a non-Rockford light curtain, or components specified by the end user, such as NEMA starters and disconnects. Remote operator-style control boxes include the clutch/brake control and are designed to be mounted close to the operator. A control transformer must be supplied separately or the existing transformer must be reused.

PROGRAMMING
The SSC-1500 press control has eight (8) user-programmable inputs (6 static-type and 2 static- or cyclic-type inputs) that can be programmed for equipment monitoring or other user-defined functions. All inputs are 24-V DC selectable current-sinking or sourcing inputs. There are three parameters that can be programmed for the six statictype inputs, and five parameters that can be programmed for the two static- or cyclic-type inputs. The three parameters are input logic, stop type, and fault message; the five parameters are input logic, stop type, fault message, open angle, and close angle. They can be assigned to each input from the list below. When a fault condition is detected, the machine will top stop or emergency stop, and the assigned message will be displayed. This feature helps when troubleshooting common fault conditions.
