User manual OMRON K3NP

[. . . ] Period Meter Timers ® K3NP An Ideal Interface for Easily Measuring the Time Interval · 50-kHz input range and 0. 08% accuracy for sophisticated control. · A wide selection of outputs: relay, transistor, BCD, linear, or communications. · Maximum/Minimum value hold, set value write protection, and more. · Banks with four comparative output values and four prescale values. [. . . ] Indicates which comparative set value is currently on the SV display. Used to return to the RUN mode from the Setting, Protect, or Maintenance mode. The process value, maximum value, or minimum value to be displayed can be selected. Used to allow the PV display to indicate set values sequentially. Used to indicate set values sequentially on the SV display. Available for Set Value LED Models only. MAX:Lit when the maximum value is indicated on the PV display. MIN:Lit when the minimum value is indicated on the PV display. PROG:Lit or flashes while parameters are being set. Lit when the teaching function is enabled and flashes when the K3NP is in teaching operation. The measurement data, maximum value, and minimum value are reset by pressing this key. Teaching is available when the teaching function is enabled. The digit being set is scrolled by pressing the Shift Key. The set value increases by one whenever the Up Key is pressed. 7.

Correct Use Long-term Use Use all products within the specified ranges. When using inside a control panel, ensure that the temperature around the product, rather than the temperature around the control panel, does not exceed the specified temperature range. Electronic products, such as this product, have a lifetime that is dependent on the lifetime of internal electronic components, as opposed to the lifetime related to the number of relay switching operations. The lifetime of these components varies with the temperature; the higher the temperature, the shorter the lifetime.
