E5 Sensor (Belt moves for 5-10 seconds) Cont.
A misaligned or damaged speed sensor can cause an E5 Sensor
error after pressing start and no sensor feedback is detected after 10
seconds.
E5 SENSOR
1. An
optical sensor
is used on our newer AC drive
systems for the TCS Series
(Reads off wheel on drive
motor)
On the optical sensor, measure DC volts between pins
2 and 3 of the speed sensor plug while plugged into the
lower board. There should be a reading of 5VDC(on)
to below 1VDC(off). Readings of 1.90VDC or higher
during the off cycle could cause the RPM LED to not
cycle and will result in a speed error.
If this speed sensor test is successful
replace the
lower board.
If the speed sensor test fails
replace the
speed sensor.
