SMP - 7000H USER MANUAL

1 YUMYUNG

1. Introduction SMP-7000H has been designed by Microprocessor control type, it can

operating have the stability, simple operation, easily expansion and com-

pact view atc.

1.1 Features

1) Stability

- It is reliable operation by Microprocessor control

- Power supply have the noise filter

- PCB has been designed with separate line as like power

line and signal line for EMI protection.

- Unit case has made by aluminium material

2) Simple operation

- It has applied the one- touch operation type with MODE and

ENT key

3) Easily Operation

- It has spare terminal of input/output signal and software margine

also.

4) Compact view (outside)

- It have many functions with compact designed by micom practice.

5) Easily A/S

- It can be changed the trouble PCB only of several PCB's

- Terminal blocks has been designed separately with main unit.

①

SAFE START LED LED is for indication of the condition of ready to start

TACHO FAIL LED

After input of fail or start of Pick-up sensor, during the

time of safety start, if RPM is not input LED shall be

lighted.

(it is for warning to inform of abnormal operation

condition)

ENG RUN LED LED is for indication of the condition of engine run.

OVER SPEED

LED

In the condition the speed limit value is established, the

LED is lighted when the speed exceeds the speed limit

value.

FUEL LIMIT LED is for indication of the Fuel limit when engine start.

② RPM Display RPM of engine in running is indicated by digital number

③ Setting Button Each Button used for system setup when RPM display for all relay output

and, Time value, ENG. RPM or T/C RPM output voltage change.

4. System Processing Methods

● Engine RPM Processing Method

Frequency (Hz) signal of engine pick-up is transmitted from

pick-up installed at Cam Gear. The proportional value and

calculating method of rotation number (RPM), frequency(Hz) and

voltage (V) are as follows.

Note: L23/30 needs 70 cam gears and L28/32 needs 74 cam gears. However, L23/30 and L28/32 should be calculated with 35 and 37 cam gears respec-tively.

● T/C RPM Processing Method

Frequency (Hz) signal of T/C Speed Pick-up is transmitted from Pick-up

installed at T/C Inside. The proportional value and calculating method of

rotation number (RPM), frequency (Hz) and voltage (V) are as follows.

Note: Number of hole for T/C Pick-up signal in medium size engine is

one.

ITEM H21/32 H25/33

Hz 1200(RPM) X 286(Gear) /60sec = 5720(Hz) 1200(RPM) X (282(Gear) /60sec = 5640(Hz)

RPM 0 ~ 1000 RPM 0 ~ 1000 RPM

Output 0 ~ 6V 0 ~ 6V

ITEM T/C MAX. RPM : 60000

Hz 60000(RPM) X (2Hole) /60sec = 2000(Hz)

RPM 0 ~ 60000 RPM

Output [V] 0 ~ 6V
