Endress+Hauser Deltabar M PMD55 Brief Operating Instructions

Deltabar M 4...20 mA HART Operation
Endress+Hauser 11
Function of the operating elements
4.2 Operation with operating menu
4.2.1 Operation concept
The operation concept makes a distinction between the following user roles:
Operating key(s) Meaning
"Zero"
pressed for at least
3seconds
Get LRV
• "Pressure" measuring mode
The pressure present is accepted as the lower range value (LRV).
• "Level" measuring mode, "In pressure" level selection, "Wet" calibration mode
The pressure present is assigned to the lower level value ("Empty calibration").
!
Note!
No function is assigned to the key if level selection = "In height" and/or calibration mode = "Dry"
• "Flow" measuring mode
There is no function allocated to the "Zero" key.
"Span"
pressed for at least
3seconds
Get URV
• "Pressure" measuring mode
The pressure present is accepted as the upper range value (LRV).
• "Level" measuring mode, "In pressure" level selection, "Wet" calibration mode
The pressure present is assigned to the upper level value ("Full calibration").
!
Note!
No function is assigned to the key if level selection = "In height" and/or calibration mode = "Dry"
• "Flow" measuring mode
The pressure present is accepted as the maximum pressure ("Max. pressure flow") and allocated to
the maximum flow ("max. flow").
"Zero" and "Span"
pressed simultaneously
for at least 3 seconds
Position adjustment
The sensor characteristic curve is shifted such that the pressure present becomes the zero value.
User role Meaning
Operator Operators are responsible for the devices during normal "operation". This is usually limited to reading process
values either directly at the device or in a control room. If the work with the devices extends beyond value
read-off tasks, the tasks involve simple, application-specific functions that are used in operation. Should an error
occur, these users simple forward the information on the errors but do not intervene themselves.
Service
engineer/tech
nician
Service engineers usually work with the devices in the phases following device commissioning.
They are primarily involved in maintenance and troubleshooting activities for which simple settings have to be
made at the device.
Technicians work with the devices over the entire life cycle of the product.
Thus, commissioning and advanced settings and configurations are some of the tasks they have to carry out.
Expert Experts work with the devices over the entire product life cycle, but their device requirements are often
extremely high. Individual parameters/functions from the overall functionality of the devices are required for this
purpose time and again.
In addition to technical, process-oriented tasks, experts can also perform administrative tasks (e.g. user
administration).
"Experts" can avail of the entire parameter set.
