Micropilot FMR62 Commissioning (installation and configuration)
Endress+Hauser 13
Two methods of configuring the device are provided, which differ mainly with regard to
the confirmation concept:
• "Increased safety mode"
While the commissioning sequence is performed, critical parameters which control
functions in the safety path are either set automatically by the device to safe values or
transferred to the display/operating tool via an alternative data format so that the
setting can be checked.
This mode can be used for standard applications. As there are only a few safety-related
parameters which can be freely configured, the risk of operating errors is greatly
reduced, and the level in the vessel does not need to be changed during commissioning
in order to check the settings.
• "Expert mode"
A larger number of safety-related parameters can be freely configured here. This means
that the device can be adapted to difficult applications. However, the settings must be
checked by directly approaching the level in the vessel or by applying a comparable
method.
One method for checking with MAX monitoring is the use of a mechanical rotary
reflector. If a rotary reflector is used, the device must be correctly configured in the
operating menu: Setup → Advanced setup → Level
Set: Max. filling speed liquid = Very fast > 2 m (80 in)/min.
A detailed description of both modes is provided in the following sections.
The SIL commissioning sequence is only visible on the display and in external
operating tools in the case of SIL devices (order code 590, option "LA"). For this
reason, SIL locking can only be activated on these devices.
4.5.3 Locking in "Increased safety mode"
To commission the device, carry out and document the following steps in the order shown:
1. Reset device. This resets all parameters to defined values. Navigate to: "Setup →
Advanced setup → Administration"
Setting: "Device reset = To factory defaults or To delivery settings"
2. Carry out parameter configuration. The parameter configuration procedure and the
meaning of the individual parameters are described in the Operating Instructions.
Observe the following parameter settings.
3. Perform a "Device check" (for more information, see the Operating Instructions). The
signal quality is checked here and any installation errors are detected. Navigate to:
"Diagnostics → Device check"
Setting: "Start device check = Yes"
4. Start the SIL/WHG confirmation sequence. Navigate to: "Setup → Advanced setup →
SIL/WHG confirmation".
Setting: "Set write protection" = enter the corresponding locking code (WHG:
7450; SIL: 7452; SIL and WHG: 7454)
In this way, forbidden parameter changes (e.g. via external operating tools if the
confirmation sequence is performed at the device display) are prevented already
during the SIL/WHG confirmation sequence.
