• After turning ON the input signal of F-202, keep it ON until the finish of the execution of the

instruction. If the input signal is turned OFF during execution of the instruction, the instruction

ends in an incomplete condition. Under this condition, next, when an F-202 instruction is given, it

will come to a “communication jam,” and the instruction will not be executed. Turn the power OFF

and then ON again for recovery.

instruction.
