Functional Safety Dual Input Smart HART® Temperature Transmitter

STZ

SECTION 1

Broken Wire Detection

During operation, the STZ sends random microamp pulses through input wiring to check for

broken wiring or a burned out sensor. By default the broken wire detection is always enabled,

and this feature is essential to ensure that dangerous failure of the sensor or signal input is

detected by the STZ and consequently alarmed.

If the STZ detects a broken wire or burned out sensor during operation, the transmitter sets the

output upscale or downscale to warn of trouble. The transmitter is able to identify the sensor

wire(s) causing the problem and indicates the fault as a message to the HART Handheld/FDT

HOST, STZ display (HP version) and by setting a HART status bit. Specific error messages

eliminate the work of removing the sensor or checking all lead wires to diagnose a problem. This

feature is especially valuable during startup.

Additionally the STZ has another feature referred to as BW (Broken Wire) Holdoff Time. This

allows users to add an additional time delay before the broken wire diagnostic alert is reported.

When enabled, a Broken Wire delay of 0-60 seconds can be set. This feature prevents the

transmitter from going into a fault state when intermittent high levels, or spikes, of extraneous

plant noise is conducted onto the sensor leads.

To setup Corrosion Detection, the user captures the nominal sensor resistance value and sets

the Warning and Alarm limits. These can be set at different levels or the same level for both.

See chart below for clarification.

Selecting Warning will set a fault message on the STZ display and send a HART message to any

HART Handheld or HART monitoring HOST. In addition an alert will be sent to any FDT host that

is communicating with the transmitter. Selecting Alarm will also drive the Analog output to Fail

Mode if the sensor is assigned to the PV. If the unit is in backup mode, and the primary sensor

has a corrosion alarm, the PV will switch to the backup sensor.
