Section 2 Preparation and Installation
2.7 Connecting the
AV2150EX Sensor
The AV2150EX sensor cable attaches to the sensor receptacle on
the 2150EX module.
To connect the AV Sensor (refer to Figure 2-22):
1. Remove the protective caps:
a. On the 2150EX, push down on the sensor release while
pulling the protective cap from the receptacle.
b. On the AV Sensor cable, pull the cap from the end of its
connector.
2. Prepare the AV Sensor connector:
a. Inspect the connector. It should be clean and dry. Damaged
O-rings must be replaced. Spare O-rings
(P/N 202-1006-69) are supplied in the 2150EX maintenance
kit (60-2059-001).
b. Coat the O-ring’s sealing surface with a silicone lubricant.
CAUTION
Do not use petroleum-based lubricants. Petroleum-based
lubricants will cause the O-ring to swell and eventually deteriorate.
Aerosol silicone lubricant sprays often use petroleum
based propellants. If you are using an aerosol spray, allow a
few minutes for the propellant to evaporate before proceeding.

3. Align and insert the connector. The sensor release will click
when the sensor connector is fully seated.
Important Information
Regarding "X" Marking
4. Connect the two caps together.
The ATEX labeling on the sensor’s serial tag shows a number
ending in "X". The X marking indicates that there are special
conditions that must be met to ensure safety, as explained on
page viii in the front of this manual.
