The new data (printout) is finally accepted into the W & M documentation.
The device is now considered being 'calibrated' again.
In order to change the system date the W&M seal has to be broken!
Therefore, it is essential to set the date before concluding the
calibration. The time is not affected.
An example of a printout of the W & M seal is given in chapter 8.5
"Print-out of electronic W & M seal" / page 117.
8.4.1 Setting of the plug-in jumper
In some cases parameters that must be calibrated have to be changed. If
you have forgotten the password or if the menu function “break seal”
(menu 4.1.3) is not available, the W & M seal must be broken manually.
Therefore, a jumper has been installed in the operating device of the
MultiFlow. The jumper is located inside the operating device at the
backside of the keypad and display board. This means it can be easily
reached even with AI installations (area subject to explosion hazards).
First switch off the unit and set the plug-in bridge into the central position.
Then switch the unit on again.
Before opening the housing and moving the jumper the lead seal must
be removed. With AI installations, the jumper is placed in intrinsically
save circuits. Thereby you may open the housing even when the device
is being used.
To obtain access to sealed parameters the plug-in contact (jumper) must
be inserted in the middle position.
If the jumper is inserted in one of the outer positions, the jumper has no
function (park position).
The MultiFlow protective mechanisms are rendered inoperative by setting
the jumper. The operator obtains access to all parameters. It will be
automatically detected that the soft seal has been broken (a warning is
displayed).
