Otherwise, minor electric shock, fire or malfunction may occasionally occur.  Inrush current of approximately 23 A will flow for a short period of time when the power supply is turned ON. If the capacity of the power supply is insufficient, the H7AN may not start. Use a power supply, breakers, an contacts with sufficient capacity. ■ Precautions for Safe Use  After turning ON the power supply, 50 ms is required for the internal circuits to reach the operating voltage.

If the indications do not change, try inputting the reset signal. If that does not work, the Counter will need to be repaired. If normal operation is recovered, it might have been caused by noise. Check for noise generation. Changes in Specifications This product was upgraded in January 2006. The main changes are described below. 1. Maximum Counting Speeds A DIP switch on models with 4, 6, or 8 digits could be used to set the maximum counting speed to 3 kHz, 5 kHz, or 30 kHz. The upgraded models have been changed so the maximum counting speed can be set to 5 kHz or 30 kHz. 2. Addition of Setting to Enable/Disable Data Backup for Power Interruptions On models that back up data when power is turned OFF (models with model numbers ending in “-M”), a DIP switch setting has been provided to enable or disable backup. 3. Changes in Functions Allocated to Function Setting Switches Some of the functions allocated to the DIP switches have been changed to allow for the changes described in 1 and 2, above. 18 H7AN ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
