VSS Pulse Amplifier Interface
Introduction
This amplifier is designed to convert the output of an existing
sensor, which generates a pulsed signal which is not compatible
with the system’s channel input requirements. This
incompatibility may be caused by insufficient voltage or lack of
output current drive capability.
The amplifier has negligible loading effect on the signal and
includes the facility to adjust its sensitivity, so can be used with a
wide variety of sensors.
WARNING! For reasons of safety, NEVER
connect the amplifier to an ABS speed sensor.
Installation
Mounting
The amplifier should be mounted, using the self-adhesive dual
locking material supplied, in a position away from strong sources
of heat and H.T. leads. It should be noted that this adhesive will
not reach full strength for up to 24 hours.
On one side of the module there is a small red LED and a
potentiometer access hole. This potentiometer is used to alter the
sensitivity and the LED is used to give visual confirmation of
correct adjustment. Access to this part should therefore be
considered when choosing a mounting position.
