NOSHOK 1800 Series Attachable Loop-Powered Indicator - Manual (Page 5)

3.1 Adjustment of the connections
The assignment of the angle-type plug is designed for the most commonly used assignments of
the respective input signals. As this is not a standardised assignment, your transmitter
assignment may not correspond to the 1800 assignment.
Standard assignment of the angle-type plug:
contact
number
wire
color
Device design
4 … 20 mA 0 … 10 VDC
pin jack pin jack
1 blue display.. + display.. - fed through, power supply +
2 red fed through fed through, GND / signal -
3 black
switching
output +
n.c. fed through, signal +
4 ( ) yellow
switching
output -
n.c. switching output n.c.
n.c. = non connected
Input signal = 4-20mA
In the angle-type plug the male contact 2 is directly connected 1:1 with the socket. The 1800
is located between the male contact 1 (+) and the jack contact 1 (-). The male contacts 3 and 4 are
used for the switching output.
If the 'Signal/GND'-line in your transmitter is not assigned to contact 2 and if the '+Supply '-line is not
assigned to contact 1, please do not forget to adjust the 1800 -angle-type plug and the
external angle-type plug accordingly. To do so open the 1800 -angle-type plug and exchange
the wire of contact 1 and contact 2 against the wire of the contact representing the connection in
your transmitter. Then exchange and rewire the two contacts in the angle-type plug of your
connecting cable.
Input signal = 0-10V
In the angle-type plug the male contacts 1, 3 and 4 are directly connected 1:1 with the socket.
The 1800 - connection is on contact 1 (power supply +), contact 2 (GND/signal-) and
contact 3 (signal+).
The male contact 4 is used for the switching output (switching to “power supply +“).
If your transmitter assignments for 'Power supply+', 'signal +' and 'GND/signal-' are different,
please do not forget to adjust the angle-type plug accordingly.
To do so open the 1800 - angle-type plug and remove the wires (blue, red and black)
entering the housing from the coupling of the angle-type plug. Connect wires with the
respective contacts, representing signal + (black wire), power supply + (blue wire) and
GND/signal- (red wire).
Then exchange and rewire the contacts in the angle-type plug of your connection cable.
