Explosion-Proof Control Switch<br />
An alternative to the automatic scroll display of parameters on the LCD, an external explosion-proof control<br />
switch (Figure A.1) allows the user to manually select which parameter is displayed on the LCD and view<br />
daily logs instantaneously without removing the instrument cover or connecting the instrument to a laptop<br />
computer.<br />

The switch mounts in either threaded conduit opening in the instrument housing. If both network<br />
communications and an RTD are required, a small junction box must be installed to establish a third conduit<br />
connection location.<br />
