Therefore, it is recommended that the Soft Cover is replaced regularly. 2. The H7CX’s panel surface is water-resistive (conforming to IP66) and so even if drops of water penetrate the gaps be- tween the keys, there will be no adverse effect on internal circuits.

Page 102 Settings for All Functions Note: At the time of delivery, the H7CX is set to the 1-stage counter (2-stage counter for H7CX-AW@/-A4W@ models) configuration. When using as a 2-stage (or 1-stage) counter, total and preset counter, batch counter, or dual counter, switch to the configuration using the procedure given on page 124.

Prescale Value (pscl) Set increment mode (UP), decrement mode (DOWN), or one of the Pulses input to the counter are converted according to the specified increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/ prescale value.
Page 104 Key Protect Level (kypt) Set the key protect level. When the key-protect switch in set to ON, 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-5). The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/OFF status of the key- protect switch after the H7CX is mounted to the panel.

Page 110 Total and Preset Counter Operation The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value. • The total counter continues to count the Reset/reset 1 total accumulated value when the present value is reset using reset/reset 1 input (reset key).
Page 111 Dual Counter Operation Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for which output turns ON when the set value matches the added or subtracted result. OUT1 and OUT2 turn ON and OFF simultaneously.
Page 112 I Operating Procedures (Tachometer Function) Switching from Counter to Tachometer The H7CX is factory-set to the 2-stage Power ON counter (1-stage counter for H7CX-AU@ models) configuration. To switch to the tachometer configuration, use the procedure shown on the right. For details, Configuration selection mode Run mode refer to page 39.
Page 113 Settings for Advanced Functions Note: When using as a tachometer, switch to the tachometer configuration using the procedure given on page 124. Settings that cannot be performed with the DIP switch are performed with the operation keys. Note: 1. If the mode is switched to the function setting mode during operation, operation will Power ON continue.tion, operation will continue.
Page 114 Explanation of Functions Tachometer Output Mode (totm) (Setting possible using Auto-zero Time (aut=) DIP switch.)
