"SELF TEST"
This message always appears when power is first applied to the WP20. The WP20 performs a
quick self-diagnostic routine and then the message disappears. This message might also appear if
terminals are shorted or if there is excessive power use by attached auxiliary equipment. It also
could appear if the WP20 power or communications wiring is too close to other devices or
wiring (high voltage power wiring, high voltage motor wiring, 120 vac, etc.).
“ZERO BELT SPEED”
This message indicates that, 1) the belt is simply not moving, 2) the belt is moving, but a speed
signal is not being generated, or, 3) the signal conditioner is defective. If the belt is moving,
make sure the green LED labeled “speed” on the SC is blinking. Note that it might appear to be
solid on if it is blinking rapidly. If it is not blinking, possible causes are a defective speed sensor
or circuit, the signal conditioner has failed, or there is no DC power. If the message appears even
when the belt is moving, check for the following adverse conditions:
•
The speed sensor wheel is not turning freely, replace it if that condition exists.
•
A broken or shorted cable from the speed sensor to the signal conditioner.
•
Loose terminal connections.
•
No +30 VDC power (+28 VDC on DC models) across terminals 29 (DC) and 10 (CM)
on the signal conditioner..
•
If power does exist, the speed signal is present, and the message persists, replace the
signal conditioner..
"-----"
This message indicates that the RATE or TOTAL values are too large to fit the display, or the
TOTAL is a negative number. Move the decimal position to the right using the Rate DP
Parameter (Section 6.02.14) or the Total DP Parameter (Section 6.02.25). Also note that the
TOTAL will need to be RESET when it reaches the upper limit.
