PROBLEMS POSSIBLE CAUSE REMEDIES
NO RATE INDICATION 1. No signal at Input A. 1. Check sensor connections.
a. Verify power to sensor.
2. Type of input signal selected incorrectly. 2. Check DIP switch setting on side of unit.
3. Rate Scale factor and/or Rate Scale Multiplier too
small.
3. Check scale factor value and scale multiplier values.
INCORRECT RATE READING 1. Input signal type incorrectly selected. 1. Check DIP switches. Set HI/LO FRQ. switch to LO
for a count speed of less than 50 Hz.
2. Inputs improperly connected. 2. Check sensor input connections.
3. Electrical noise interference. 3. Check power source for noise.
a. Check signal wire routing.
4. Scale factor incorrect. 4. Verify scale factor value.
5. Rate input signal too high of a frequency. 5. Verify input signal.
RATE DISPLAY FLASHING OVERFLOW 1. Rate Scale Factor, Multiplier and/or Conversion
Factor values too large.
1. Check values.
2. Minimum update time set too high for input rate. See
Note in “Programming Rate” Section.
