A tempered glass window requires the use of the supplied magnetic
wand/screwdriver to activate the four user interface switches
located on the front of the display module. This allows for non-
intrusive setup and operation.
A locking screw integrated into the cover provides positive
locking that can be loosened by using the supplied 2mm hex
key.

POD
The POD ( P ersonality, O ptions, and D isplay) includes circuit
boards for the personality module, optional interfaces, and
display.
The personality module, or circuit board, determines the
transmitter behavior based on the sensor type attached to
the transmitter (electrochemical cell, catalytic bead sensor, or
infrared) and provides the necessary interface. Connection to the
attached sensor is made through the sensor connector.
The optional communication boards vary depending on the
option selected when ordered. Only one of the three available
interface options (relays, Modbus, or FOUNDATION Fieldbus)
can be attached to the transmitter.
