Stack ST200 User manual

Stack Clubman Tachometer
(Model ST200)
Important Note
Your Tachometer is delivered in demonstration mode.
If you have not set the cylinders the tachometer will
automatically start running when you connect the Power.
Mounting
Fits 80mm (3.25”) cut out. Insert in hole, fit U
bracket and tighten down Nyloc nuts.
Note this Tachometer does not require
any protection against vibration.
Connections
Red wire to a switched 12V supply.
e.g. Ignition switch (Kill Switch on competition
vehicles).
Orange wire to the appropriate tachometer signal
pickup point.
Refer to table on following page
Blue wire to one terminal of the switch, and
the other side of the switch to a convenient
ground point (Black).

Setting Engine cylinders (IMPORTANT please read)
The tachometer is factory set in demonstration mode.
.
.
.
. If you power up the Tachometer
without setting the cylinders the pointer will automatically start moving.
Set the cylinders as follows:
1. Press & hold the switch .
.
.
.
.and apply power to the tachometer.
2. Release the switch when the pointer has stopped resetting on the stop pin.
3. Press the switch immediately .
.
.
.
.to select the number of cylinders - the pointer will
move to show the number of cylinders selected.
e.g. Press 4 times for 4 cylinders (pointer will point to 4000 RPM)
4. When the desired number of cylinders have been selected wait j

j3 seconds and
the tachometer will resume normal operation with the new setting.
5. To check the setting repeat operations 1 & 2 above, the pointer will move to the
selected number of cylinders. After 3 seconds the unit will revert to normal mode.

Note: For 2 stroke ignition systems set the cylinders to double the actual number of cylinders.
For multi-coil ignition systems use the tach output provided or connect to one coil only and
configure the tacho for the cylinders the coil fires.
When using a dedicated Tacho output check the number of pulses per engine
revolution :- 1 pulse per rev = 2 cylinders (4 stroke) = 1 cylinder (2 stroke)

Maintenance
The tachometer is sealed to IP67 and requires zero maintenance - there are no wearing
or consumable parts. Removal of the rear can will invalidate your warranty.
Please complete and fax us the enclosed warranty form to ensure you will enjoy a
fast and efficient service in the unlikely event you suffer problems with your unit.
Troubleshooting
If you have problems with the operation of the tachometer then please check the follow-
ing:
1. Recheck all electrical connections.
2. If the back-light doesn’t work check power and ground connections.
3. If the back-light is on but the tachometer doesn’t work check that the pickup wire is
connected correctly to the ignition system.
Note that certain ignition systems provide a very low voltage Tacho output and
may require a signal amplifier (ST492)
4. Tell tale not working. Check switch wiring and ground connection.
5. If the tachometer shows a constant RPM, check the switch is not shorting out.
6. If the reading is erratic check the following:
That the pickup connection is OK.
Check for possible Points bounce, float or poor ignition grounding.
Check Tachometer ground is the same as ignition system.
7. Tachometer reading too high or too low.
Check the cylinders set up is correct

The pointer will initially move to the highest RPM value, then
after 5 seconds the needle will move to the full scale of the dial
and sweep down to zero.
Only when the pointer reaches zero will the memory be
reset.
Normal Operation
When power is applied to the tachometer, the pointer will reset moving backwards
against the stop before moving to the current RPM (Zero RPM if the engine is not
running). When power is removed, the pointer is held at its’ last position (it doesn’t
necessarily return to zero)
Press and hold the switch as if you were to reset the Tell Tale
memory (see section above).
When the pointer sweeps down to zero - resetting the Tell Tale
memory, continue holding the switch for a further 5 seconds.
The pointer will then move to the current setting for the Shift-
RPM.

Tell Tale Memory
To Recall the Tell Tale Memory
The pointer shows the highest RPM seen since the memory
was last reset.
Note: The Tell tale will be remembered even when the power is off.

.Release the switch. Now each time the switch is pressed or
held on the pointer will increment 50 RPM. If the pointer
reaches full scale it will return to zero and start to increase
again.
When the desired Shift-RPM has been reached, release the
switch and wait 3 seconds. The pointer will then move to zero,
indicating that the Shift-RPM has been set.
Note: The Shift-RPM will be remembered even when the power is off.
