Maintenance
Take the following steps to set the measuring system to “Maintenance” mode before
starting maintenance work.
▸
Connect the control unit with the computer. Start SOPAS ET.
▸
Connect with the MCU(DH Ex) (
see “Connecting the control unit”, page 57
).
▸
Enter the Level 1 password (
see “Password for SOPAS ET menus”, page 68
).
▸
Set the sender/receiver unit to “Maintenance”: Click “Maintenance sensor”.

Resuming measuring operation
Resume measuring operation after completing the work (deactivate the “Maintenance on/
off” checkbox in the “Maintenance / Operation” window and click “Set State”).
●
Maintenance” mode can also be set using the buttons on the optional control unit LC
display (
) or by connecting an external maintenance switch to
the terminals for Dig In2 (17, 18) in the MCUDH Ex-3K and MCU control units (
“Processor boards connections of control units”, page 60
).
●
An automatic functional check is not carried out during “Maintenance”.
●
The value set for “Maintenance” is output on the analog output (
analog outputs parameters”, page 79
). This is also applicable when a malfunction is
present (signaled on relay output).
●
The “Maintenance” mode is reset when there is a voltage failure. In this case, the
measuring system switches automatically to “Measurement” after the supply voltage
is switched on again. If “Maintenance” mode is set via the external maintenance
switch (see top item), the mode is also maintained when there is a voltage failure.
