Applications

• Genset Monitoring: Track diesel or gas generator runtime for scheduled oil and filter changes.
• HVAC Systems: Monitor the total operational hours of industrial chillers and heavy-duty compressors.
• Manufacturing Machinery: Calculate MTBF (Mean Time Between Failures) and OEE (Overall Equipment Effectiveness) on the factory floor.
• Water Pumps: Track the usage of agricultural or municipal water pumping stations.

Unlock New Capabilities

• Past Projects: You've likely been relying on the operator's memory, paper logbooks, or basic microcontroller timing scripts that reset on power loss.
• The Feature Upgrade: This mechanical hour meter unlocks permanent, non-volatile time tracking. Because the gears physically move, the reading is permanently saved without needing a backup battery or EEPROM memory.
• Effort / Requirements: Intermediate Level. Requires cutting a specific mounting hole in your control panel door and safely routing AC mains wiring.

Virtual Technician & Wiring Guide

• ⚠️ SAFETY WARNING: MAINS AC VOLTAGE. This component operates at dangerous line voltages. Always ensure the main breaker is OFF before installation.
• Wiring Concept: The meter must be wired in parallel with the load you want to track.
• Pin 1 (AC Line): Connect to the switched AC output that powers your machine.
• Pin 2 (Neutral): Connect to the common AC Neutral line.
• Note: Since it is AC, polarity between Line and Neutral on the meter terminals does not strictly matter, but following standard color codes is recommended for safety.

Frequently Asked Questions (FAQ)

• What is the operating voltage for the GIC LA25F1?
  It accepts a very wide input range from 90 VAC up to 264 VAC, making it compatible with standard 110V and 230V systems.
• Can this be used on a DC power supply?
  No, this specific model (LA25F1) is designed exclusively for AC single-phase power.
• Is the meter reading resettable to zero?
  No. To prevent tampering with maintenance logs, industrial analog hour meters like this one cannot be reset.
• What happens to the reading if the power goes out?
  The mechanical dial physically locks in its current position. It will not lose its value during a power outage; no batteries are required.
• How do I read the decimal value on the dial?
  The dials in white/black represent full hours, while the contrasting dial (usually red or distinct) represents tenths of an hour (6-minute increments).
• Does it require a separate power supply to operate?
  No, it powers its internal synchronous motor directly from the AC voltage it is measuring.
• Can I use this to track a 3-phase motor?
  You can, but the meter itself must be powered by a single phase. You would wire the meter between one of the live phases (L1, L2, or L3) and the Neutral line.
• What is the standard panel cutout size required?
  Please refer to the GIC datasheet for the exact millimeter dimensions, but it fits standard rectangular/square industrial panel cutouts.
• Does polarity matter when wiring AC?
  For the meter's operation, it does not matter which terminal gets Line and which gets Neutral.
• Is this hour meter waterproof?
  The front face typically has a basic dust/splash rating (like IP54/IP65 depending on mounting), but the rear terminals are exposed. It must be mounted inside an enclosure.
• Will this work on a 60Hz power grid?
  Yes, it is compatible with both 50Hz and 60Hz AC frequencies.
• How much power does the meter itself consume?
  It consumes a very negligible amount of power (usually under 1 or 2 Watts) just to run the internal timing motor.
• What gauge wire should I use for the terminals?
  A standard 18 AWG or 16 AWG copper wire is more than sufficient, as the current draw is extremely low.
• Can it handle vibrations from a diesel generator?
  Yes, panel-mount mechanical meters are designed to withstand standard industrial and mechanical vibrations.
• How do I mount it to the panel?
  Slide the meter through the cutout from the front of the panel, and secure it from behind using the included mounting clips or brackets.
• Does this measure actual load current?
  No, it only measures the time that AC voltage is present at its terminals. It does not know if the motor it is attached to is actually drawing current.
