When using a two-wire sensor, select NPN input. The same setting is used for all external inputs. For details on input connections, refer to Input Connections on page page 9. This setting can be used to prevent output chattering if the measurement value fluctuates slightly near the set value. The measurement value after prescaling is set.
H7CX-A@-N Tachometer ON Count Alarm Set Values for Outputs 1 and 2 (OUT1 and OUT2) (on1a and on2a) Set the ON count alarm values for the outputs 1 and 2. The limit can be set to between 0 × 1000 (0 times) and 9999 × 1000 (9,999,000 times). Only the underlined values are set. The alarm will be disabled if 0 is set. If the total ON count of instantaneous output 1 or 2 exceeds the alarm set value, e3 will be displayed on the Timer to indicate that the output ON count alarm value was exceeded.

H7CX-A@-N Switching between Preset Counter, Total and Preset Counter, Batch Counter, Dual Counter, Twin Counter, and Tachometer Operation Select which H7CX configuration is used (i.e., preset counter, total and preset counter, batch counter, dual counter, twin counter, or tachometer) in configuration selection mode. The H7CX is also equipped with a DIP switch monitor function, a convenient function that enables the settings of the DIP switch pins to be confirmed using the display on the front of the H7CX.
H7CX-A@-N Key Protect Level It is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the key protect level (KP-1 to KP-7) when the key-protect switch is set to ON. The key protect level is set in the function setting mode. The key protect indicator is lit when the key-protect switch is ON.

H7CX-R@-N Explanation of Functions Advanced Functions Basic Functions Decimal Point Position (dp) Input Mode The mode can be switched between tachometer mode and AMDcompatible mode. Tachometer Mode Use this mode to measure the pulse frequency (Hz). AMD-compatible Mode Use this mode to measure the pulse cycle (s). Cycle (s) Counting Speed Set the maximum counting speed (30 Hz/10 kHz) for input. If contacts are used for input signals, set the counting speed to 30 Hz.
H7CX-R@-N Startup Time (stmr) Key Protect Level (ypt) In order to prevent undesired output resulting from unstable input immediately after the power supply is turned ON, measurement can be prohibited for a set time at startup. It can also be used to stop measurement and disable output until the rotating body reaches the normal rate of rotation, after the power supply to the H7CX and rotating body are turned ON at the same time. Set the key protect level. Refer to Key Protect Level on page page 48.

H7CX-R@-N Precautions for the H7CX-R In upper and lower limit output mode, if the comparison value setting is such that comparison value 1 ≥ comparison value 2, the output will always be ON. Hold Function The measurement value (display value) and output are sustained while the hold input is ON. Note: The output will maintain the current status when the hold key is pressed.
H7CX-R@-N Precautions on Replacing the AMD-S The H7CX-R11-N is the recommended model for replacing the AMD-S-series Motion Detector. Refer to the following precautions before replacing the AMD-S.
H7CX-@-N Safety Precautions for All H7CX Series (Common) CAUTION Do not allow pieces of metal, wire clippings, or fine metallic shavings or fillings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction. Minor injury due to explosion may occasionally occur. Do not use the Counter where subject to flammable or explosive gas. Fire may occasionally occur. Tighten the terminal screws to the rated torque. H7CX terminals: 6.55 to 7.97 lb-in (0.74 to 0.
H7CX-@-N Precautions for Correct Use • H7CX models with a 12 to 24-VDC power supply use a transformer-free power supply method in which the power supply terminals are not isolated from the signal input terminals. If a nonisolating DC power supply is used, unwanted current paths may occasionally burn or destroy internal components depending on the wiring. Always check the wiring sufficiently before use. • An inrush current of approx. 10 A will flow for a short time when the power supply is turned ON.
