C. Analog 4/20mA source (not powered) and sink (powered) inputs
Wire 4/20mA source and sink inputs
•
Install 4/20mA analog device according to manufacturer’s instructions.
•
Use diagrams below to connect device to IOEM channel.
•
Follow polarity from 4/20mA to IOEM channel as shown in the diagrams
below.
•
Configure 5X00 E-Aux systems using AquaManager PC software. Complete
E-Aux system configuration information is provided in the AquaManager
Help system.
Analog 4/20mA source input device Analog 4/20mA sink input device
CAUTION:
Observe correct polarity as shown in diagram.
Directions to wire temperature inputs
Any 5X00 instrument E-Aux system can be configured as a temperature input.
Temperature sensors for these systems have 2 wires and are terminated at location
G
and
H
for IOEM-8 and at location
G
for IOEM-4. Temperature sensor(s) must
be thermistors with 10K at 25
˚
C, see
Appendix 4 Alpha A Curve
WARNING: Disconnect external power to the unit before wiring.
AVERTISSEMENT : déconnectez l’alimentation externe de l’unité avant d’effectuer
un câblage quelconque.
1.
Perform steps 1 - 3 of IOEM and REM installation.
2.
Install temperature probe(s), see 5400 and 5500 user manual for probe
installation information;
3.
4.
Feed temperature probe cable through drilled hole in rubber grommet
to location
G
and
H
for IOEM-8 and at location
G
for IOEM-4. The
terminal strip is removable.
Installation and Wiring
CAUTION
: Run high and low voltage cables through separate bulkhead and
conduit.
5.
Terminate temperature sensor wires to selected IOEM channel. There is
no polarity for temperature sensor wires; therefore, (+) and (-) terminals
are interchangeable. Make sure temperature sensor wires are terminated at
the (+) and (-) terminals for the particular Eaux channel being configuring.
6.
Complete wiring to all IOEM I/Os that will be used in application.
7.
8.
Configure 5X00 E-Aux systems using AquaManager PC software.
Complete E-Aux system configuration information is provided in the
AquaManager Help system.
9.
Test E-Aux/IOEM wired systems including display, control, and/or alarm
functionality based on the particular user-defined configuration.
Directions to wire 4/20mA Outputs
5X00 instrument systems including pH, DO, temperature, conductivity, ORP, E-Aux
and aux can be configured to
output
a 4/20mA signal that can then be connected
to a non powered device, like a PLC, allowing use of the 4/20mA signal by other
programs. See the diagram below to wire a 4/20mA output
WARNING: Disconnect external power to the unit before wiring.
AVERTISSEMENT : déconnectez l’alimentation externe de l’unité avant d’effectuer
un câblage quelconque.
1.
Perform steps 1 - 3 of IOEM and REM installation.
2.
3.
Feed 4/20mA output wires through drilled hole in rubber grommet to
location
G
and
H
for IOEM-8 and at location
G
for IOEM-4. Terminal
strip is removable.
CAUTION:
Run high and low voltage cables through separate bulkhead and
conduit.
4.
Use (+) and (-) pins for wire terminations that will relay 5X00 system
4/20mA signal to external device, such as a PLC-see diagram below.
note:
-
4/20mA outputs can only source current, 4/20mA outputs cannot
sink current.
