7.
Configure 5X00 system relays using AquaManager PC software or directly
through the instrument front panel. Complete relay configuration informa
-
tion is provided in 5X00 user manuals. Use AquaManager PC software
Help system to configure relays from a PC.
8.
Test relays. See

, 5X00 instrument user
manuals.
Wiring a Contactor
The four onboard relays are rated at 250VAC@10AMPs. Contactors should be
used for devices drawing current loads higher than relay specification. See figure
3.6 for contactor wiring.
Note:
-
Contactor must meet the electrical requirements of the load.

Installation and Wiring
Step 5 Wire I/Os on IOEM
Wire IOEM channel devices according to their application. IOEM channels can be
configured as input or output devices. See IOEM configuration options starting on
page 70. IOEM channels can be configured one of three (3) ways: 1) as an input
to use with one of the 5X00 instrument’s E-Aux systems which E-Aux system would
be configured to monitor, control and/or alarm and datalog that E-Aux system.
(E-Aux systems are also referred to as “virtual inputs.”) 2) as a 4/20mA output for
5X00 sensor systems including pH, ORP, conductivity, temperature, DO and aux and
E-Aux systems. The 4/20mA
output signal can then be used by another connected
device such as a PLC.
3) as an PID 4/20mA output for 5X00 pH, ORP, conductiv-
ity, temperature, DO, and non digital aux and E-Aux systems allowing PID control
devices, such as a value, to open and close based on system value.
IOEM-8s have
8 I/Os which are terminated at locations
G
and
H.
IOEM-4s have 4 I/Os which
are terminated at location
G.
Diagrams and directions for wiring all input and output types are provided in the
following manual sections. Use IOEM wiring diagram on inside of front panel for
identification of I/O channel number and pin position.
IOEM input configuration
IOEM channels can be configured for 0-1volt, 0-5volt, 4/20mA (powered and
unpowered), digital and temperature input devices.
These input devices use 5X00
instrument E-Aux systems to monitor, control and alarm the specific input values.
Note:
-
All IOEM inputs have input protection, the maximum input voltage
should not exceed 6 VDC.
Directions to Wire (non temperature) IOEM
Inputs
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.
Install input device according to manufacturer’s specifications.
4.
Feed aux device wires through drilled hole in rubber grommet to locations
G
and
H.
Terminal strip is removable.
