The following wiring diagrams show the One Series
Field Safety System™
fully configured where the health status (IAW) and SRO switch status signals are
being monitored by a logic solver (PLC or DCS). These connections are not required; however, UE recommends monitoring the IAW signal to maximize the safe
failure fraction in an SIS application. Additionally, wiring the SRO to an external load (final element) is not required.
For direct control of a final element from the One Series
Field Safety System™
, Figures 11-13 show the recommended SRO wiring methods. The wiring con-
nection shown at TB2 – A+B is required for proper operation of the SRO Monitor diagnostics only if this feature is turned ON in the menu. The default factory
setting for SRO Monitor is OFF.
