IMS-4814 Ultra Low Temperature Sensor
Installation Instructions
Introduction
The IMS-4814 Ultra Low Temperature Sensor is
designed to connect to the IMS-1000 and monitor
temperatures in refrigerators or freezers. The electrical
connection between the sensor and IMS-1000 is made
via the attached RJ-45 patch cable. The sensor probe
may be secured inside equipment using the included
clamp or it may be hung using tie wraps. Do not install
the black plastic enclosure inside of a refrigerator or
freezer.
Cabling
The Ultra Low Temperature Sensor comes with an
attached 7' cable with an RJ-45 plug on the end and a weatherproof probe with 12' of cable. If the
sensor installation is close to the IMS-1000, you can plug it directly into an IMS environmental
input. If the cable is too short you can use the included RJ-45 adaptor and a longer patch cable to
extend the length. For applications where the sensor may be far from the IMS unit, you may utilize
your existing network wiring infrastructure. For example, the sensor may be installed in another
room or another floor. Connect the sensor to your structured wiring network via an RJ-45 jack. At
the other end, connect a patch cable from your structured wiring patch panel directly to the IMS-
1000 environment input.
Caution: The IMS sensors are not TCP/IP devices and therefore should not be
connected directly to any wiring infrastructure that is connected to network equipment
such as a hub, router, or switch. Sensors use RJ-45 plugs and cables similar to those
used with Ethernet devices.
Mounting
The temperature sensor housing may be mounted directly on a surface using double-sided tape
(included) or it may be secured to equipment using tie-wraps. The choice depends on your
application. The sensor probe must be installed in your refrigerator or freezer at a location that
is representative of the average temperature. Do not install the probe directly in front of the
cold air blower.
Configuration
All IMS Solution sensors are auto-configured when you plug them into the IMS-1000. The
Ultra Low Temperature Sensor will identify itself as a 4-20mA transducer. On the Properties
screen for this sensor you must select the sensor type: either Low Temperature (Deg F) or Low
Temperature (Deg C). When a sensor is removed, or the connection is disrupted, the
configuration data remains intact but the sensor will go into trouble status and generate a
trouble alarm. When the sensor is plugged in again, or the connection is re-established,
configuration data remains unchanged and the sensor returns to normal operating condition.
