5. Setup and Installation

5.1 Product Mounting

The hour meter is designed for easy drill-in and snap-in mounting. Ensure the panel cut-out matches the specified dimensions for a secure fit.

• Drill a rectangular hole in the desired mounting surface with dimensions of 36.88mm (1.45 inches) by 24.5mm (0.96 inches).
• Insert the hour meter into the cut-out. The snap-in design will secure it in place.

This image shows a diagram of the required panel cut-out size (36.88mm x 24.5mm) and an illustration of how the hour meter snaps into the panel for secure mounting.

5.2 Power Connection

The hour meter can be connected directly to a power source or through a power switch. The two pins on the meter are not distinguished by positive or negative polarity, simplifying the connection process.

• Direct Connection: Connect the two pins of the hour meter directly to the AC/DC 5V to 277V power source.
• Power Switch Connection: For applications requiring the meter to activate with the machine, connect one pin to the power source and the other pin to the machine's power switch (e.g., ignition switch).

Figure 6: Wiring diagrams for direct and power switch connections.

This image illustrates two wiring methods: a direct connection where the hour meter is continuously powered by an AC/DC 5V to 277V source, and a power switch connection where the meter activates when the machine's power switch (like an ignition key) is turned on.

6. Operating Instructions

Once properly installed and powered, the Runleader Digital LCD Hour Meter will begin tracking hours automatically.

6.1 Total Hours (TOT)

The meter continuously displays the total accumulated working hours of the machine. This value is non-resettable by default and is stored even when power is off due to the internal battery.

• The display shows "HOURS" and the total accumulated time.
• The hourglass icon on the display will flash when the meter is actively recording time.
• The total hours can be programmed to a specific starting value using the optional PG600 programmer, useful for new meter installations or replacements.

6.2 Resettable Hours (TMR1 & TMR2)

The meter provides two resettable timers, TMR1 and TMR2, which can be used to track hours for specific tasks or maintenance intervals.

• To view TMR1 or TMR2, press the button on the front of the meter. Subsequent presses will cycle through TOT, TMR1, and TMR2.
• To reset TMR1 or TMR2, navigate to the desired timer display, then press and hold the button until the value resets to zero.

6.3 Programming with PG600 (Optional)

For advanced configuration, such as setting initial total hours or specific partial hour values, the Runleader PG600 programmer (sold separately) can be used.

• Refer to the PG600 programmer's manual for detailed instructions on connecting and programming the hour meter.

7. Maintenance

The Runleader Digital LCD Hour Meter is designed for minimal maintenance due to its robust construction and sealed design.

• Cleaning: Wipe the meter's surface with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
• Water Resistance: The IP68 rating ensures the meter is highly resistant to water and dust. No special maintenance is required for water protection.
• Data Storage: The built-in CR2050 battery ensures that all recorded data is saved automatically, even if external power is lost. The battery is designed for long-term data retention and is not user-replaceable.
