[. . . ] H090-E1-01B E5CK Digital Controller (Programmable Type) USERS MANUAL Preface The E5CK T is a high performance programmable digital controller. The E5CK T al lows the user to carry out the following: · Set program patterns to each step by time or ramp rise rate · Execute advance, hold and reset step operations · Execute continuous operation of all patterns and repeated operation of same patterns · Check the start of each step or program end time by signals. · Count time from the beginning of each step (time signal) · Select from many types of temperature and analog input (multi input) · Select output functions such as control output or alarm output (output assignment) · Monitor the control loop by LBA (Loop Break Alarm) · Use the communications function · Calibrate input or transfer output · The E5CK T also features a watertight construction (NEMA4: equivalent to IP66). This User's Manual describes how to use the E5CK T. [. . . ] · This parameter can also be used in the program mode.
