FAULT CURRENT
In addition to the discrete IAW™ and Safety Relay Output status signals, the One Series
Field Safety System™
includes a 4-20 mA output that
adheres to the NAMUR NE 43 current level standard. Figure 14 deatails these current levels and what they indicate.
A diagnostic fault will force the IAW™ Safety Relay Output and Status to the fail safe state and the (≤ 3.6 mA) fault condition.
