1
The same function as in tolerance judgment output mode.
*
2
"L" when output data is fixed.
*
3
During input, the output of pin numbers 3 through 26 and pin number 31 is "H".
Output circuit
Transistor is on when the output is "L" (open collector).

•
When using relays, incorporate a surge-current-absorbing diode or a protective
circuit. If no protection is incorporated, the IC in the Counter may be damaged.
• The output current when the tolerance judgment result is output is
20 mA at maximum.
Input circuit
Input is valid when the input voltage is "L".

Counter data
Tips
•
After acquiring the counter data, there is a maximum 10 ms delay before the
tolerance judgment result is output.
•
For EG-101D, the length of time until the tolerance judgment result is output
after the counter data enters in the Specification range depends on the
connected equipment, such as the Linear Gage.

Troubleshooting
When the Counter does not operate as expected, refer to the cause of the
trouble and the solutions shown below:
Cause
Solution
Symptom 1: The counter value is incorrect (not counting).
Parameters are not correctly
set for the type of the Linear
Gage, etc.
Set correct parameters. For details,
see
Peak mode (MAX or MIN is lit)
is active.
Cancel Peak mode. For details, see
"4.2 Peak Mode Setting" (page 5).
The HOLD signal (UNIT is
blinking) is being input.
Check the external input.
Calculation with a constant
function is set.
Cancel calculation with a constant
function. (Set parameter number 16 to
0.)
Symptom 2: Cannot execute Zero setting.
Peak mode is active.
Cancel Peak mode. For details, see
"4.2 Peak Mode Setting" (page 5).
The Preset value is a value
other than 0.
Set the Preset value to 0. For details,
see
