The Protecting Frame (provides overlapping of unevenness after
mounting box walling-in) and Canopy (necessary for installation in external
areas) form other accessories for flush-mounted installation. When installed in
surroundings with possible water condensation (temperature changes) or water
spraying (rain) it is recommended to connect the jumper on basic module –
heating ON.
The
board heating
has two positive functions partly it heats up the
electronics in winter at temperatures below –20°C (most details with extended
temperature range has guaranteed parameters from –20°C) and partly with
external installation at swift temperature changes and higher air humidity by
switched heating no water condensation occurs on basic guard board, which
assures its reliable function.
1.5 Change of nameplates
The first step is
dismantling of
a fixing frame
from module, where
we want to change a nameplate. It
can be executed by unscrewing of
two screws under plastic covers on
fixing frame. When removing the
fixing frame we can see two
independent modules. The
front part
(metallic) of the button module has to be first separated from plastic part in this
way that we will put off the
plastic lug
, ensuring the front part on the right side.
Each button has its separate nameplate hold by means of plastic flag (see
figure). The paper nameplates can be printed from Excel form (to be
downloaded on
www.alphatech.cz
) or from Nset setting program.
