PROBLEMS POSSIBLE CAUSE REMEDIES
NO DISPLAY 1. Power off. 1. Verify power.
2. Improperly wired. 2. Check wiring.
3. Voltage selector switch in the wrong position. 3. Check switch position.
4. Power in a Brown out condition. 4. Verify voltage reading.
5. If powered by +12 VDC source, not enough current to
drive Legend unit.
5. Verify Source current rating.
CHECKSUM
ERROR 1 OR 2 ON DISPLAY 1. Data error detected by processor. 1. Press “ENT” key.
a. Check all programming parameters.
2. Check signal lines for possible noise sources.
UNIT DOES NOT COUNT 1. No input signal. 1. Check sensor connections.
