Runleader Rotating Shaft Hour Meter Tachometer

1. Introduction

The Runleader RL-HM019C is a versatile hour meter and tachometer designed to monitor the running hours and RPM values of any rotating shaft, gear, or pulley on external equipment. It is suitable for a wide range of applications including lawn mowers, generators, compressors, marine engines, diesel/gas engines, and other process/power equipment. This device helps in tracking engine usage, monitoring real-time RPM, and reminding users of scheduled maintenance.

2. Features

• Tachometer (RPM) Function: Displays real-time RPM values when external equipment is operating, detected via a magnetic sensor. Helps in adjusting engine idle. The maximum RPM value is viewable and resettable.
• Hour Meter (TOT) Function: Accumulates total running hours (TOT) when external equipment is off. This value is non-resettable and has 1-minute/1-hour accuracy.
• Job Timers (JOB1 & JOB2): Two resettable timers to record the duration of specific work jobs.
• Maintenance Service Timer (SVC): Programmable countdown timer for maintenance intervals. The display flashes when the SVC time is reached.
• Magnetic Signal Detection: Utilizes a magnetic sensor for accurate RPM and hour tracking.
• LCD Display Shutdown: Features a display shutdown function to conserve power.
• Waterproof Rating: IP68 rated for strong water resistance.
• Certifications: CE and RoHS certified.

4. Setup and Installation

4.1 Magnetic Signal Pickup Installation

The tachometer functions by detecting the rotation of a shaft or gear using a magnetic sensor. Ensure the magnetic pickup sensor is securely positioned near the rotating part of the equipment you wish to monitor. The sensor detects the magnetic field generated by a magnet attached to the rotating component.

4.2 Product Mounting

The RL-HM019C offers two primary mounting options:

• Stick-on Mounting: Use the provided double-sided tape to adhere the unit to a clean, flat surface.
• Screw-on Mounting: Utilize the pre-drilled holes on the unit and the included screws to securely fasten it to a surface.

5. Operating Instructions

5.1 RPM and Total Hours (TOT) Display

When the external equipment is running, the display will show the real-time RPM. When the equipment is shut off, the accumulated total hours (TOT) will be displayed. The maximum RPM value can also be viewed directly.

5.2 Job Timers (JOB1 & JOB2)

The device includes two independent job timers, JOB1 and JOB2, which can be used to record the hours for specific tasks or work periods. These timers are viewable and resettable, allowing for tracking of individual job durations.

5.3 Maintenance Reminder (SVC)

The programmable maintenance service timer (SVC) allows you to set a countdown for scheduled maintenance. Once the set time is reached, the display will flash to remind you that service is due.

6. Maintenance

The Runleader RL-HM019C is designed for durability and minimal maintenance. Its IP68 waterproof rating ensures protection against dust and water ingress, making it suitable for harsh environments.

• Cleaning: Wipe the display and casing with a soft, damp cloth. Avoid abrasive cleaners or solvents.
• Battery Replacement: The unit uses an internal lithium metal battery. Refer to the full user manual for specific instructions on battery replacement, if applicable.
• Magnetic Sensor: Ensure the magnetic sensor and magnet are free from debris or corrosion to maintain accurate readings.

7. Troubleshooting

If you encounter issues with your Runleader RL-HM019C, consider the following:

• No RPM Reading: Check the magnetic sensor's placement and ensure the magnet on the rotating shaft is properly aligned and securely attached. Verify the sensor cable is not damaged and is correctly connected.
• Inaccurate Readings: Ensure the magnetic sensor is not too far from the magnet. Interference from strong electromagnetic fields nearby can also affect accuracy.
• Display Not Working: The unit includes a lithium metal battery. If the display is completely blank, the battery may need replacement. Refer to the full user manual for battery access.
• SVC Reminder Not Activating: Double-check that the SVC timer has been programmed correctly and that the countdown has reached zero.

8. Applications

The Runleader RL-HM019C is suitable for a variety of equipment with rotating shafts, including but not limited to:

• Lawn mowers
• Compressors
• Motorcycles
• Outboard motors
• Chainsaws
• ATVs
