CAUTION
The sensor threads can be coated with an
appropriate grease to ease both the initial
installation and future replacement of the sensor.
Detector Electronics offers a silicone free grease
that is especially suited for use with catalytic type
combustible gas sensors (see “Ordering
Information” for part number). The use of other
lubricants is not recommended, since some
materials can cause irreversible damage to the
sensing element. SILICONE based lubricants or
compounds must NEVER be used.
Screw the transmitter board to the standoffs as shown in
Figure VII-37. Connect the sensor plug to the
transmitter board.
Attach the communication module to the standoffs
mounted on the transmitter board. Connect the ribbon
cable from the terminal wiring board to the
communication module.
Set the address for the device. Refer to “Device
Address Switch Setting” in the “Switch Setting” section
of this manual for complete information regarding the
switch setting procedure.
