Tachometer Sensors
There are two types of Tachometer Sensors available through ZF
Mathers, Mechanical (p/n 8902) and Magnetic Pickup (p/n
8912). Both types provide two separate outputs, one for the
tachometer(s) and the second output provides the Processor’s
tachometer signal requirement. If a sensor other than one sup-
plied by ZF Mathers is used, it must meet the criteria provided
below for each type:
3-1.10.1 AC Coupled Sensors
•
The signal must have a minimum amplitude of +/- 1.5 V (3.0 V
P-P).
• The signal’s maximum amplitude must not /- 100 V
(200 V P-P).
• The frequency of the signal must be no lower than 30 Hz at
Idle.
• The signal’s frequency may not exceed 8 KHz at Full Throttle.
3-1.10.2 Alternator
• The pre-rectified stator AC terminal may be used as the tach
source.
• The signal is inputted to the AC Coupled Sensor input.
• The signal must meet the same criteria as any AC Coupled
Sensor Signal (refer to Section 3-1.10.1).
3-1.10.3 Point side of the Coil
• When the signal is sourced from the coil or an electronically
produced tach signal (used on some gasoline engines) the sig-
nal is connected to the AC Coupled Sensor input.
• The signal must meet the same criteria as any AC Coupled
Sensor Signal (refer to Section 3-1.10.1).
3-1.10.4 Active Sensors (Open Collector Output)
• The sink current ability of the Sensor may be no lower than 2
mA.
• The operational current may not exceed 50 mA.
• The Sensor must have a maximum saturation voltage of 0.8 V.
• An operational voltage requirement of 9- 10 VDC.
• A minimum frequency of 5 Hz at Idle.
• A maximum frequency of 8 KHz at Full Throttle.
