Red Lion C48C - Manual (Page 49)

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. For
further technical assistance, contact technical support at the numbers listed on the back cover of this instruction manual.

2. Check signal lines for possible noise sources.
a. Check all programming parameters.
a. Check presets, prescaler, and output time values.
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.
2. Inputs improperly connected.
5. Prescaler incorrect.
4. Incorrect counting mode.
3. Electrical noise interference.
