6 Maintenance
6.1 General
The maintenance work to be carried out is limited to cleaning work and securing the purge
air supply function.
Take the following steps to set the measuring system to “Maintenance” mode before
starting maintenance work.
Set the measuring system to “Maintenance” state before starting maintenance work. This
can be done using either an external contact on pins 1 and 6 of plug connector 3 (see
“Sender/receiver unit”, page 15, see “Connecting the sender/receiver unit”, page 30) or
with SOPAS ET.
▸ Connect the MCU to the laptop/PC using the USB cable and start SOPAS ET.
▸ Connect with the MCU (see “Connection to the device via USB line”, page 40).
▸ Enter Level 1 password (see “Password for SOPAS ET menus”, page 40).
▸ Set the measuring system to “Maintenance” mode.

Resume measuring operation after completing the work (deactivate the “Maintenance
Sensor” checkbox in the “Set on operation mode” window).
Maintenance intervals
The equipment operator must specify the maintenance intervals. The period depends on
existing operating parameters such as dust content and state, gas temperature, how the
equipment is run and ambient conditions. Therefore only general recommendations can be
made here. Normally, the maintenance intervals are about 4 weeks during the initial period
and can be steadily incremented to up to a year depending on the respective conditions.
The equipment operator must specify the specific work to be carried out and its
performance in a Maintenance Manual.
WARNING:
Observe the relevant safety regulations as well as the safety notices (see “Responsibility
of user”, page 8) during all work.
● An automatic function check is not carried out during “Maintenance”.
● The value set for “Maintenance” is output on the analog output (see “Factory set-
tings”, page 43, see “Factory settings”, page 36). 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
voltage is switched on again.
