The ERR LED of the FP2 Multi - wire link unit is lighted or blinking.
Procedure 1
If the ERR LED is lighted, turn the power off and then on again, several times.
Procedure 2
If the ERR LED is blinking, the procedure noted below may also be carried out.
Status What to do
ERR LED blinking (intervals of
approx. 1.0 seconds) Check to make sure the CPU is Ver. 1.05 or a subsequent
version.
This can be checked by looking at the side panel seal on
the CPU or the NPST - GR software status screen.
ERR LED is blinking (intervals of
approx. 0.2 seconds), and COM LED
is lighted. Check the parameter settings program, and see if there are
overlapping link area allocations. (If so, change one to a
number in the link which is not being used, and which is
allocated to that link area.)
Check the parameter settings program, and see if there are
overlapping unit numbers.
ERR LED is blinking (intervals of
approx. 0.2 seconds), and COM LED
is not lighted. Check to see if all the unit numbers are in the range of 1 to
64, and re - boot.
If operation is not possible, regardless of whether or not the above items are correct,
please contact your dealer. Also, if you have a spare link unit, replace the one being used
with the spare unit and check the operation.
