TROUBLESHOOTING
The majority of problems can be traced to improper connections or incorrect set-up parameters. Be sure all connections are clean and tight, that
the correct output board is fitted, and that the set-up parameters are correct. Also, be sure the DIP switch settings and the User Input Plug Jumper
position are correct for the particular application.
PROBLEMS
POSSIBLE CAUSE REMEDIES
NO DISPLAY
1. Power off. 1. Verify power.
2. Loose connection or improperly wired. 2. Check connections and wiring.
3. Brown out condition. 3. Verify power reading.
4. Bezel assembly not fully seated into rear of unit. 4. Check installation.
5. If powered by +12 VDC source, not enough current to drive C48. 5. Verify Source current rating.
Err 1 DISPLAYED AT 1. Data error in count values detected by processor. 1. Press key.
POWER UP 2. Check signal lines for possible noise sources.
Err 2 DISPLAYED AT 1. Data error in preset, prescaler, or output time values 1. Press key.
POWER UP detected by processor. a. Check presets, prescaler, and output time values.
2. Check signal lines for possible noise sources.
Err 3 DISPLAYED AT 1. Data error in programming parameters detected 1. Press key.
POWER UP by processor. 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.
a. Verify power to sensor.
2. Type of input signal incorrectly selected. 2. Check DIP switch settings.
3. Count inhibited. 3. Disable count inhibit.
4. Prescaler value too small. 4. Check prescaler value.
UNIT COUNTS
1. Input signal type incorrectly selected. 1. Check DIP switches. Set HI/LO FRQ. switch to LO for
INCORRECTLY 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. Incorrect counting mode 4. Verify count input mode.
5. Prescaler incorrect. 5. Verify prescaler.
