FUNCTIONNAL DESCRIPTION
Application /System Performances
- No separate start wire into module is required
- Switch occurs at approximatly 12Hz but can be
changed within a narrow region
1. Reluctance sensor input.
- Minimum input level of 200mV peak to peak
- Maximum input level of 40V peak to peak
5. Input noise immunity is provided by hysteresis on the
input comparator.
2. Hall sensor input
- Open collector output desirable.
- Input level of 0.5V to Vbat
- 100mV of hysteresis is in slow speed mode
- 500mV of hysteresis in run mode
3. Operating voltage range
- Normal range from 9V to 16V.
-Operational range with some modiÞcations to
parameters from 6V to 24V.
6. Dwell control is modiÞed under different operating
conditions.
- In slow speed mode dwell follows the duty cycle of the
input signal
- In normal run mode dwell is controlled at 16% of cycle
time plus coil rise time to current limit level.
- At high speed (determined by coil rise time) dwell is
75% of input cycle time.
4.Transient considerations
- Load dumps should not exceed +90V peak with 250ms
time constant.
- Field decay should not exceed -90V peak with 25ms
time constant.
7. Output current is normally 5.5 +/- 0.5 Amps. It can be
operated at higher or lower limits if required. (Not excluding
7.5 Amps).
5. Operating temperature range
- Continuous operation : -30°C to 125°C
8. Start Retard
6. Rate of acceleration should not exceed 250Hz/s from
20Hz to 300Hz (input frequency). If this is exceeded the
module will still function but an occasional spark may be
missed and dwell calculations will be negated for one or two
output cycles.
On slow speed mode, a retard signal is generated that is
inversely proportional to input frequency. The retard is
nominally 4.8% at 1Hz, (related to input duty cycle) and can
be modiÞed to meet other application requirement.
9. High voltage on the output transistor is nominally
clamped at 350V but can be adjusted if necessary.
7. Normal operating frequency range is from 1Hz to
400Hz.
10. High Battery voltage operation
- At a battery voltage of 16V the dwell is modiÞed in run
speed to 10% of cycle time plus coil rise time.
- At a battery voltage of approximately 30V the module
will shutdown to prevent damages to the output devices.
Application features and functions
1. Power on : On initial power up there will be no output
current and this condition will be maintained until the Þrst
input cycle is run at the input terminals.
2. Push start capability :The unit may be push started as
any input signal exceeding 200mV peak to peak will produce
a peak
3. Stall shutdown : If for a period of 5 seconds no input
signal is present, the unit will shutdown and output current
will be reduced at a rate slow enough to present a spark.
4. Automatic switching from a slow speed to run mode at
a preset frequency.
