Further information on programming
For the Promag 33 measuring system, there is a wide choice of functions and parame-
ters which the user can set individually and adapt to the condition of his process.
The individual functions are allocated to various function groups (see page 37).
Selection of these functions within the E+H matrix is carried out as described on
page 36. Numerical values or factory settings which may be altered appear flashing
on the LC display.
Please note the following:
• If the power supply cuts out, then all calibrated and set values are safely stored in
the EEPROM (without requiring batteries).
• Certain functions can be set to “OFF”. The appropriate functions in other function
groups then no longer appear on the display.
• In certain functions, a prompt is given after entering data for safety reasons.
Select “SURE? [YES]” with the 6 keys and confirm by pressing 1 again.
The setting is now stored or a function, e.g. an empty pipe adjustment, is activated.
Achtung!
Enable programming (access code)
Normally programming is locked. Any unauthorised changes to the instrument
functions, values or factory settings are therefore not possible. Only when a
code has been entered (factory setting = 33) parameters can be entered or
changed.
The use of a personal code number which can be freely chosen prevents
unauthorised personnel from gaining access to data (see page 77).
An exception to this is the function group “BATCHING”. In this group only the
function “BATCH VARIABLE” is protected by the code number. All other
functions in this group can be changed without the code number.
Caution!
• If programming is locked and the 6 keys are pressed in a given function,
then a prompt to enter the code automatically appears on the display.
• With code “0” (zero) the programming is always enabled!
• If the personal code number is no longer available, then please contact the
Endress+Hauser service organisation which will pleased to help you.
• Changing certain parameters, e.g. all characteristic data of the sensor,
affects a number of functions of the entire measuring system, especially its
accuracy. Normally these characteristic data may not be altered and are
therefore protected by a special service code only known to E+H service
technicians. Please contact your E+H Service organisation for more
information.
Locking programming
• After returning to the HOME position, programming is again locked after
60 seconds if no operating element is pressed.
• Programming can also be locked by entering any number (not the customer
code number) in the function “ACCESS CODE”.
