Output allocation Key protect level Note: 1. At the time of delivery, the H7CX is set to the 1-stage counter (2-stage counter for H7CX-AW@/-A4W@ models) configuration. 2. Set to output 2 time when using as a 2-stage counter or batch counter.
Page 18: Operating Procedures (Counter Function)
For details, refer to page 36. Note: 1. Be sure to set pin 1 of the DIP switch to ON. If it is set to OFF, the DIP switch settings will not be enabled. 2. Changes to DIP switch settings are enabled when the power is turned ON.
Page 19 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 36.
Page 20 25 pulses Set the way that control output for the present value is output. The possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H. Output Encoder modes other than N, F, C, or K-1 cannot be set using the DIP switch and so use the operation keys if other modes are required.
Page 21 When the key-protect switch is 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 59: Safety Precautions
Safety Precautions (Common) Note: The following precautions are common for all H7CX models. • Leaving the H7CX with outputs ON at a high temperature for a long CAUTION time may hasten the degradation of internal parts (such as electrolytic capacitors). Therefore, use the product in combination Loose screws may occasionally result in fire or malfunction.
Page 60: External Power Supply
Power supply voltage (VDC) Power Suppies • Turn the power ON and OFF using a relay with a rated capacity of 10 A minimum to prevent contact deterioration due to inrush current caused by turning the power ON and OFF.
