2.3 Commissioning on the bench with HART
Commissioning consists of testing the Rosemount 4600 and verifying transmitter
configuration data. The transmitter can be commissioned either before or after installation.
Commissioning the transmitter on the bench before installation using a Field
Communicator or AMS Device Manager ensures that all transmitter components are in
working order.
To commission on the bench, connect the transmitter and the Field Communicator or AMS
Device Manager. Connect Field Communicator leads at any termination point in the signal
loop.
In order to commission the transmitter, the power supply must provide 11.25 to
42.4 V dc at the transmitter terminals. A current meter is also required to measure current
output. To enable communication, a resistance of at least 250 ohms must be present
between the Field Communicator loop connection and the power supply. Do not use
inductive-based transient protectors with more than 3 mH of inductance with the
Rosemount 4600.
When using a Field Communicator, any configuration changes made must be sent to the
transmitter by using the “Send” key (F2). AMS Device Manger configuration changes are
implemented when the “Apply” button is selected.
For more information on the Field Communicator, see 475 Field Communicator website for
the most up to date literature. AMS Device Manger help can be found in the AMS Device
Manager online guides within the AMS system.
2.3.1 Setting the loop to manual
Whenever sending or requesting data that would disrupt the loop or change the output of
the transmitter, set the process application loop to manual. The Field Communicator or
AMS Device Manager will prompt you to set the loop to manual when necessary.
Acknowledging this prompt does not set the loop to manual. The prompt is only a
reminder; set the loop to manual as a separate operation.
2.3.2 Wiring diagrams
Bench hook-up
Connect the bench equipment as shown in Figure 2-1 and turn on the Field Communicator
by pressing the ON/OFF key or log into AMS Device Manager. The Field Communicator or
AMS Device Manager will search for a HART-compatible device and indicate when the
connection is made. If the Field Communicator or AMS Device Manager fail to connect, it
indicates that no device was found. If this occurs, refer to Section 5: Troubleshooting.

Rerange with a Field Communicator only
The easiest and most popular way to rerange is to use the Field Communicator only. This
method changes the values of the analog 4 and 20 mA points independently without a
pressure input.
From the HOME screen, enter the Fast Key sequence shown.
1. At Keypad Input select 1and use the keypad to enter lower range value.
2. From Keypad Input select 2and use the keypad to enter upper range value.
Rerange with a pressure input source and Field
Communicator
Reranging using the Field Communicator and a pressure source or process pressure is a way
of reranging the transmitter when specific 4 and 20 mA points are unknown.
Note
The span is maintained when the 4 mA point is set. The span changes when the 20 mA point
is set. If the lower range point is set to a value that causes the upper range point to exceed
the sensor limit, the upper range point is automatically set to the sensor limit, and the span
is adjusted accordingly.
1. From the HOME screen, enter the Fast Key sequence shown to configure lower and
upper range values and follow the online instructions.
Rerange with a pressure input source and the
local zero and span targets (option D1)
1. For Zero based lower range values (gauge only):
Vent the transmitter.
For Non-Zero based lower range values:
Using a pressure source with an accuracy 3 to 10 times the desired calibrated
accuracy, apply a pressure equivalent to the lower range value to the transmitter.
2. Using the supplied magnetic adjustment tool, touch and hold the magnetic end to
the zero adjustment target for at least two seconds, but no longer than ten
seconds.
3. Using a pressure source with an accuracy 3 to 10 times the desired calibrated
accuracy, apply a pressure equivalent to the upper range value to the transmitter.
4. Using the supplied magnetic adjustment tool, touch and hold the magnetic end to
the span adjustment target for at least two seconds, but no longer than ten
seconds.

2.7.3 Damping
The Damp command introduces a delay in processing which increases the response time of
the transmitter; smoothing variations in output readings caused by rapid input changes.
Determine the appropriate damp setting based on the necessary response time, signal
stability, and other requirements of the of loop dynamics of your system. The default
damping value is 0.4 seconds and is user-selectable from 0.3 to 60 seconds.

2.8 Detailed setup
2.8.1 Failure mode alarm and saturation
The Rosemount 4600 Transmitter automatically and continuously perform self-diagnostic
routines. If the self-diagnostic routines detect a failure, the transmitter drives the output to
configured alarm values. The transmitter will also drive the output to configured saturation
values if the applied pressure goes outside the 4-20 mA range values.
Note
The failure mode alarm direction can also be configured using the Field Communicator or
AMS Device Manager.
Note
Under some failure conditions, the transmitter will ignore user configured alarm conditions
and drive the transmitter to low alarm.
The Rosemount 4600 Transmitter have three configurable options for failure mode alarm
and saturation levels:
Rosemount (Standard), see Table 2-1
Custom, see Table 2-2
Table 2-1. Rosemount (Standard) Alarm and Saturation Values
Level 4–20 mA saturation 4–20 mA alarm
Low 3.9 mA ≤3.75 mA
High 20.8 mA ≥21.75 mA
Table 2-2. Custom Alarm and Saturation Values
Level 4–20 mA saturation 4–20 mA alarm
Low 3.7 mA — 3.9 mA 3.6 mA — 3.8 mA
High 20.1 mA — 21.5 mA 20.2 mA — 23.0 mA

Configuration
Failure mode alarm and saturation levels can be configured using a Field Communicator or
AMS Device Manager, see “Alarm and saturation level configuration” on page 13. Per
Table 2-2, custom alarm and saturation levels can be configured between 3.6 mA and
3.9 mA for low values and between 20.1 mA and 23 mA for high values. The following
limitations exist for custom levels:
Low alarm level must be less than the low saturation level
High alarm level must be higher than the high saturation level
High saturation level must not exceed 21.5 mA
Alarm and saturation levels must be separated by at least 0.1 mA
The Field Communicator or AMS Device Manager will provide an error message if a
configuration rule is violated.
2.8.2 Alarm and saturation level configuration
To configure alarm and saturation levels with a Field Communicator or AMS Device Manager
perform the following procedure:
Field Communicator
1. From the HOME screen, follow the Fast Key sequence under Alarm and Saturation
Levels.
2. Select 7, Config. Alarm Level to configure alarm levels.
3. Select OK after setting the control loop to manual.
4. Select OK to acknowledge current settings.
5. Select desired setting, if OTHER is selected, enter HI and LO custom values.
6. Select OK to acknowledge the loop can be returned to automatic control.
7. Select 8, Config. Sat. Levels to configure saturation levels.
8. Repeat steps 3-6to configure saturation levels.
