Emerson Rosemount 327T, Quick Start Manual

Page: 5 / 26

1 Introduction
The Rosemount 327T Temperature Transmitter detects media temperature and converts
it into an analog output signal (4 - 20 mA). The temperature transmitter includes an IO-
Link interface for configuring parameter settings or viewing process and diagnostic data.
1.1 Getting started
Follow these steps to configure the temperature transmitter for normal operation.
Procedure
1. Connect the temperature transmitter to a PC to set parameters using IO-Link.
2. Set the standard unit of measurement in °F or °C (
Uni ). (See Adjustable parameters )
3. Set the analog signal. (See Analog function )
• OU2 : I = 4-20 mA or Ineg = 20-4 mA
• ASP and AEP : scaling of the measuring range.
4. Configure Drift Monitoring. (See Setting range for drW and drA )
• drW : drift threshold at which the temperature transmitter signals "warning".
• drA : drift threshold at which the temperature transmitter signals "alarm".
•
ddr
: Drift Monitoring Diagnostic delay.
5. Set which diagnostic cases the temperature transmitter signals using drEd . (See
Diagnostic cases )
• ON : only failure diagnostic cases
• ONdr : alarm and failure diagnostic cases
•
OFF
: warning, alarm, and failure diagnostic cases
6. Configure analog signal for diagnostic cases ( FOU2 ). (See Adjustable parameters )
•
ON
: 21.5 mA
• OFF : 3.5 mA
7. Configure switching signal for diagnostic cases in three-wire operation (
dOU1
). (See
Diagnostic function (three-wire) )
• dOU1 : Output opens, closes, or pulsates; according to configuration.
8. Configure output logic for diagnostic output in three-wire operation ( P-n ). (See
Adjustable parameters )
• pnp
•
npn
9. Complete all other necessary parameter settings.
