ASSEMBLY AND INSTALLATION
3
Using a suitable line (
see “General information, prerequisites”, page 44
), the MCU-N
control unit (without integrated purge air supply) can be located up to 1000 m away from
the sender/receiver unit.
We therefore recommend fitting the MCU in a control room (measuring station or similar) to
ensure free access to the MCU. This considerably simplifies communication with the
measuring system in order to set parameters or to locate malfunction or error causes.
It is advantageous to provide weather protection (tin roof or similar), to be made onsite, for
use outdoors.
Requirements when using the MCU-P control unit
The following is applicable in addition to the general specifications:
●
Install the MCU-P control unit at a location with clean air whenever possible. The air
intake temperature must correspond to specifications in the Technical data (
). In unfavorable conditions, lay an air intake hose to a location
with better conditions.
●
The purge air hoses to the sender/receiver unit and reflector/scattered light receiver
should be as short as possible.
●
Whenever possible, lay the purge air hoses so that no water can collect.
●
We recommend using the optional external purge air unit when the sender/receiver unit
and reflector are more than 10 m away from the MCU control unit.
