If
“ESC” is indicated in the LC display of the remote display unit, you must adopt protective
measures before entering the room where the sensor unit has been installed.
Check the room’s
ventilation and find out whether there is a CO
2
leak, wearing protective clothing / equipment. As soon as
the CO
2
concentration in the ambient air has reached the second alarm thr
eshold, “ESC” appears in the
display of the sensor unit as well as in the display of the remote display unit. The yellow LED “FLT”
(standing for fault) flashes. Use the
„ReFactSet“ function to reset the gas leak detector to factory defaults.
The “ESC” indication should now disappear. Alternatively, you can remove the mains adaptor and plug it
back into the socket.
The remote display unit shows the readings and safety warnings of the sensor unit. It is connected to the
sensor unit via a communication cable (cable length: max. 8 m). the remote display unit should not be
placed in the same room as the sensor unit. It should be mounted in a way which provides high visibility
and an easy reading of the CO
2
concentration before entering the room where the sensor unit is located.
The connection between both devices can be checked by using the “DIAG” function which is described in
the further course of this manual. To reset the PCE-
WMM 50, the “Reset” key on the sensor unit is used.

Open the box and take out the sensor unit, the remote display unit and all accessory parts.
Mount the sensor unit in the area which you want to monitor. It should be placed 0.45 m above the
ground and as near as possible to the pipes and valves. Mount the wall mounting to a wall by using 4
screws. The sensor unit can be placed in the mounting afterwards. Make sure that the sensor unit sits in
the mounting tightly.
Mount the remote display unit outside of the room to be monitored. Mount the wall mounting to the wall by
using screws. The display unit can be placed in the mounting afterwards. Make sure the display unit sits
in the mounting tightly.
