Maintenance
5.1
General
The maintenance work to be carried out consists of:
●
Cleaning work (
see “Maintenance on the sender/receiver unit and reflector/scattered
●
Securing the purge air supply function (
see “Cleaning the optical interfaces on the
),
●
Checking/correcting the alignment of the optical axes of sender/receiver unit and
reflector (
see “Focussing the sender light beam for transmission measurement”,
Take the following steps to set the measuring system to “Maintenance” mode before
starting maintenance work.
▸
Connect the MCU to the laptop/PC using the USB line and start program SOPAS ET.
▸
Connect with the MCU (
see “Connection to the device via USB line”, page 55
▸
Enter the Level 1 password (
see “Password and operating levels”, page 84
▸
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”).
WARNING:
Observe the relevant safety regulations as well as the safety notices (
) during all work.
●
“Maintenance” mode can also be set using the buttons on the display on the MCU
(
) when the LC-Display option is present or by con-
necting an external maintenance switch to the terminals for Dig In2 (17, 18) in the
MCU (
see “Connecting the MCU control unit”, page 47
).
●
An automatic function check is not carried out during “Maintenance”.
●
The control window on the rear of the reflector/scattered light receiver (
spot on the back of the enclosure of the reflector/scattered light receiver”, page 62
)
is lit for better inspection of the optical alignment in the “Maintenance” mode.
●
The value set for “Maintenance” is output on the analog output (
analog outputs parameters”, page 71
). 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 operating volt-
age is switched on again.
