    SPEED MEASURING UNIT USER MANUAL (ESP-2000-BS)

    Applied to HIMSEN (H25/33, H21/32) and L27/38 Engine, this intrinsically safe SPEED MEASURING UNIT is designed to take frequency values measured by SPS-02 Pick-Up Sensor(for Engine RPM) and TPS Pick-Up Sensor(for T/C RPM), mounted onto Flywheel Cover, and thereon calculate the two RPMs by applying the number of Teeths, providing Driver outputs to drive Engine-related Relay.

    3-1. ENGINE RPM MEASURING
    Speed Measuring Unit receives frequencies, measured by Pick-up Sensor(for Engine RPM) mounted onto Flywheel Cover, and internally reduces RPM as lllustrated below and thereon operates related outside Engine RPM sRelay by using its built-in Driver.

    Classification Calculated Frequency [Hz] RPM Output [V]

    H21/32 1200(RPM)286(Gear) /60Sec =5720 Hz 0 ~ 1200 RPM 0~6V

    (Tacho Fail is removed when Sensor is properly connected or when Power is reset.) In case that RPM does not reach 50(fixed) within 5 sec after Start Signal becomes on, it caused the status of Fail. (Tacho Fail is removed when Engine RPM is 200 or over or at the time of Power resetting) In case that RPM sharply decreases 200(fixed) to 0, it causes the status of Fail in 1 second. (Tacho Fail is removed when Engine RPM is 200 or over or at the time of Power resetting) 3-2-2. SAFETY START (Relay contact: Normal Open): Terminal 8 This output works 5 seconds after RPM becomes 0 duing Power supply The output works 5 seconds after RPM becomes 0 when Safety Start is off, indicating the stoppage of Engine The output is removed when Tacho Fail is caused, Safety Start Off RPM is exceeded, or Engine Start Signal becomes on. 3-2-3. ENGINE RUNNING (Relay contact: Normal Open): Terminal 9 This output indicates the status of Engine running. It works when Engine speed is more than Engine Running On RPM or 200, or Engine Running Delay Timer completes its counting. The output is removed when Engine Speed decreases again from Engine Running On RPM or over to Engine Running Off RPM or below. The output is removed when Engine RPM becomes 200 or below after Engine running provided Engine Running Delay Timer completes its counting 3-2-4. OVERSPEED (Relay contact: Normal Open): Terminal 10 This output works when Engine speed is Enginer Over Speed On RPM or over The output is removed when Engine speed becomes 10% of Engine Over (i.e. : 828 -(8280.1) = 745)
