IOEM product description
IOEM instruments are configured as slave devices on an RS485 network. IOEM
channels (I/Os) are used by 5X00 systems as additional I/Os on the network.
IOEM
instruments have either 4 I/O channels (IOEM-4) or 8 I/O channels (IOEM-8).
AquaManager (PC software) is required to configure an IOEM mode on a
network.
IOEM channels can be configured in the following three (3) ways:
1.
As an Input
- configure IOEM channel as a digital,
analog (0-1V, 0-5V,
4/20mA) and/or temperature input. These inputs are configured, monitored
and controlled using a 5X00 instrument E-Aux system. See
IOEM input chan-
nel/eaux configuration-page 72
.
2. As a 4/20mA PID output control device
(such as a valve) to control any 5X00
instrument pH, ORP, temperature, Conductivity, DO, non digital aux and E-Aux
system. 5X00 system must be configured in PID 4/20mA control mode. See
page “Configure 5X00 system for IOEM PID output control device” on page 77
3. As an output, converting a 5X00 system input to a 4/20mA output signal to
be used by some external device such as a PLC-
page 76- Convert any non
digital 5X00 sytem [pH, ORP (mv), temperature (F/C), Conductivity, (mS/
μS),
DO (%sat/mg/l), aux and E-Aux] to a 4/20mA output signal.
IOEM use case input
-5X00 instruments have 8 eaux systems. 5X00 instrument eaux
systems are used to allow peripheral input devices (digital, analog and temperature)
to be monitored, controlled and alarmed across a network. An example - a 4/20mA
pH probe is configured and wired to an IOEM instrument, the 4/20mA ph probe
input is configured at a 5X00 eaux system. The 4/20mA ph system can now be
monitored, controlled and alarmed over the network. E-Aux “virtual systems” can
be configured in a variety of ways that allow flexibility to the user.
IOEM use case 4/20mA output
- a 5200A instrument’s pH value is sent as a 4/20mA
signal to a third party device such as a PLC.
The 4/20mA signal can then be used
by the third party device for additional processing.
notes:
-
One IOEM input can be assigned to multiple 5X00 E-Aux systems.
-
One IOEM 4/20mA output can be assigned to only one 5X00 system.
REM product description
REM instruments are configured as slave devices on an RS485 network. REM
channels (outputs) are used by 5X00 systems as additional relay outputs on the
network.
REM instruments have 4 relay outputs that are used to connect peripheral
devices . These peripheral devices are used to control and/or alarm networked 5X00
instrument systems.
Introduction
REM use case output
-The master 5X00 instrument receives information that a slave
5X00 DO system on the network is in DO low control range. The DO low control
relay for this 5X00 slave is configured to relay 2 on a networked REM. The master
sends a command to the networked REM that relay 2 needs to energize to control
slave 5X00’s low DO value. Slave REM instrument, relay 2, energizes until the
master receives a message from the slave 5X00 DO system value is ≥ to that DO
system’s setpoint.
note:
-
Multiple 5X00 systems can be assigned to the same relays.
Preview of User Manual
This manual includes safety, installation, wiring and maintenance information for
IOEM and REM instruments.
This manual is intended to be used with 5X00
instrument manuals and AquaManager PC program help system for IOEM
and REM configuration.
Read Chapter 2
“Safety Information,”
starting on page 16, before installing or
configuring IOEM and REM systems.
Chapter 3
“Installation,”
starting on page 24, provides information on how to
install the IOEM and REM components, and peripheral devices. Only
qualified
people should install IOEM and REM expansion modules. Do not attempt to install
or configure these devices if you are not
qualified
to do so. If information is not
clear, DO NOT PROCEED until clarification can be obtained. All wiring involving
connections to main power must be performed by a qualified licensed electrician
and must conform to all locally applicable electrical codes.
Chapter 4
“Using AquaManager to configure IOEM and REM Channels,
” starting
on page 70, provides quick start guides on how to use AquaManager to configure
IOEM and REM I/O channels to 5X00 instrument systems. 5X00 user manuals con-
tain detailed information on 5X00 instrument menu structure and how to properly
configure IOEM and REM instruments to 5X00 systems.
“Notes”
are presented at the end of certain manual sections to provide additional
information to help clarify IOEM and REM operation and features.
Appendices include information on Unpacking & Inspection, Troubleshooting,
Declaration of Conformity, Alpha “A” curve (a reference for temperature sensors)
Parts and Accessories, Warranty, Contact Us and Recycling information.
An index is provided starting on page 96.
