Rosemount 3051S

NOTES

1.Transmitter output is not safety-rated during the following: configuration changes, multidrop, loop test. Alternative means should be used to ensure process safety during transmitter configuration and maintenance activities.

2.DCS or safety logic solver should be configured to match transmitter configuration. Figure 15 identifies the three alarm levels available and their operation values.

high saturation

(1)Transmitter Failure, hardware or software alarm in LO position.

(2)Transmitter Failure, hardware or software alarm in HI position.

(3)High alarm must be at least 0.1 mA higher than the high saturation value.

(4)Low alarm must be at least 0.1 mA lower than the low saturation value.

Setting the alarm values and direction is dependent on whether or not the hardware switch option is installed. You can use a HART master or Field Communicator to set the Alarm and Saturation values.

Switches installed

1.If using a Field Communicator, use the fast key sequence to set the Alarm and Saturation values.

2.Manually set the direction for the Alarm to HI or LO using the ALARM switch as shown in Figure 5 on page 7.

Switches not installed

If using a Field Communicator, use the fast key sequence to set the Alarm and Saturation values and the Alarm Direction.
