halted by wiring the terminals T1 and T2 as shown in the following table.

During emission halt, the control output (OSSD 1/2) is off and the emission halt indicator
(orange) lights up.
If the machinery is not stopped, the cause may be a malfunction due to extraneous noise or an
abnormality in the control output (OSSD 1/2) or the auxiliary output, also from the machine.
