• Digits (None): 6-digit negative transmissive LCD display (-99999 to 999999 value range).
• Settings (None): Single-stage threshold limit evaluation setting.
• Supply Voltage (None): High-voltage operating supply accepting 100 to 240 VAC at 50/60 Hz.
• External Connections (None): Direct rear-panel screw terminal connection interface.
• N: Revised hardware generation with enhanced front bezel display optics and reduced housing depth.

Electrical & Mechanical Parameters

Microprocessor Execution & Firmware Flash Compatibility

The integrated digital processing core processes input signal frequencies up to 10 kHz without missing pulse events. Internal system registers maintain firmware flash compatibility across setting parameters, writing current count values and configuration setpoints to non-volatile EEPROM memory without battery support. Embedded boot checks execute flash checksum validation during power initialization, preventing output state activation until internal DC supply rails fall within regulated voltage limits.

Field Cabinet Installation & Wiring Rules

Panel Door Mounting

• Cut a standard 45 mm x 45 mm square opening in the cabinet enclosure door; slide the rubber gasket onto the bezel before panel insertion to meet IP66 front sealing.
• Insert the counter body into the panel cutout and slide the rear mounting adapter clamp forward until it locks flush against the door interior.

Electrical Connections & Noise Isolation

• Connect line power conductors to the rear M3.5 screw terminals using insulated crimp ring lugs; torque terminal screws to 0.5 N-m.
• Run high-speed input lines from NPN/PNP sensors through shielded cables, grounding the braid shield to a single cabinet earth point to suppress high-frequency noise interference.

Frequently Asked Questions

• What supply voltage inputs are supported by the standard AC model?

  The unit operates on 100 to 240 VAC line power at 50/60 Hz connected across the rear supply terminals.

• What load rating is specified for the transistor output?

  The solid-state transistor output supports up to 30 VDC at 100 mA maximum for direct interface to PLC digital inputs.

• How are system settings protected during unexpected power outages?

  Internal EEPROM non-volatile memory retains process configuration settings, setpoints, and active counts without requiring a battery.

• What display range is provided on the 6-digit screen?

  The 6-digit negative transmissive LCD screen displays values from -99999 to 999999 with configurable decimal point positions.

• What wiring interface is used on the rear panel?

  The unit utilizes integrated rear M3.5 screw terminals for direct conductor connection without an external socket.

• How is water and dust resistance achieved on enclosure doors?

  Installing the instrument with the provided rubber sealing gasket maintains an IP66 equivalent water and dust barrier.

• Can the unit be switched between counter and tachometer modes?

  Yes, internal parameters allow mode selection between preset counter, totalizing counter, and tachometer rate modes.

• Does the input terminal accept both NPN and PNP sensor types?

  Yes, input signal logic is configurable for either NPN or PNP proximity sensors and rotary encoders via menu settings.
