6.3.2 Magnetic mount option
Figure 7: Magnetic mounting option
Take the magnetic mounting base and thread onto
the exposed set screw from the bottom of the
SELD-102 Node unit. The magnetic mounting base
(with the SELD-102 Node unit attached) can now
be attached to any metal structure in a vertical
position.

mounting base installed
6.3.3 NPT mount option
This option is usually used for pressure and
temperature sensors. The base of the SELD-102
Node
unit has a ½” MNPT connection that allows it
to be mounted to any ½” female NPT connection.
Figure 9: Bottom of SELD-102 Node unit with
MNPT port
The pressure sensor allows for measuring the
pressure of any fluid flowing into the NPT port.
For the temperature sensor option:
1. Mount flush against the end of the NPT
port to measure the temperature of
whatever surface it is in contact with
6.4 Connecting sensors and power-up
If not already completed, install sensor on
equipment to be monitored.
If applicable, follow the sensor specific connection
instructions shown in the table below.
Table 6: Specific Sensor Connection
Instructions
Sensor Type Connection Instructions
4-20mA This device is polarity sensitive.
The red wire must connect to
the MOST positive power of the
loop. Reversed polarity will
result in damage to the device.
Discrete Wiring carries no voltage but will
detect a contact closure.
Change of state on the contacts
will determine the state of the
signal transmitted. The SELD-
102 Node unit will send
supervisory information at a pre-
determined interval, telling the
receiver that the SELD-102
Node is online and functional.
If available, remove the magnetic set screw (at the
top of the unit) to power up the SELD-102 Node.
6.5 LED Indications
The SELD-102 Node has two LED indicator lights
to signify various states. See table below for
description of each state.
