1.2.2 EV (Electric clean water Valve)
OMD-2008 EV instruments are equipped with an electric switchover valve for the
clean water stream. The valve can be controlled via the menus, or remotely using
the control input.
1.2.3 MCU (Manual Cleaning Unit)
Optionally the instruments can be fitted with a Manual Cleaning Unit. The Manual
Cleaning Unit allows to clean the sample glass tube without opening the
Measuring Cell Head Screw, and without interrupting the normal sample flow.
Maintenance is made easier with the MCU. Please note that operating the MCU
may set the instrument to alarm condition for a few seconds.
