CAUTION:
Run high and low voltage cables through separate bulkhead and
conduit.
5.
Use (-) and (+) pin for selected input channels 1-4 for IOEM-4 and 1-8
for IOEM-8 to terminate wires. Terminate the ground wire to the (-) loca-
tion. The 24V pin is used only when wiring a 4/20mA nonpowered device
that requires 24V loop power from the IOEM to power the 4/20 device.
6.
Please see individual diagrams for wiring IOEM input devices:
A. digital device, page 45;
B. 0-1 and 0-5 volt device, page 45;
C. 4/20mA (powered/sink) and (not powered/source) devices, page 46;
D. temperature sensor instructions (no diagram provided), page 46
CAUTION
: Inputs are not isolated. Devices connected must be electrically
isolated from ground and the water.

Configure 5X00 E-Aux systems using AquaManager PC software.
Complete E-Aux system configuration information is provided in the
AquaManager Help system.
10. Test E-Aux/IOEM wired systems including display, control, and/or alarm
functionality based on the particular user-defined configuration.
Installation and Wiring
A. Wire Digital input
Wire Aux Digital Input
•
Install digital input device according to manufacturer’s instructions.
•
Use 2 wires to connect Digital input device to an IOEM channel.
•
Digital devices are mechanical and do not require power.
•
Connect switch wires to an IOEM I/O channel. There is no polarity for digital
input device wires; therefore, (+) and (-) terminals are interchangeable.
•
Configure 5X00 Eaux systems using AquaManager PC software. Complete
Eaux system configuration information is provided in the AquaManager
Help system.
Digital input switch
CAUTION:
Do not input external voltage.
B. Analog 0-1 and 0-5 Volt input
Wire Analog 0-1Volt and 0-5 Volt Input
•
Install 0-1 and/or 0-5 Volt analog device according to manufacturer’s in-
structions.
•
Use 2 wires to connect device to an IOEM channel.
•
Follow polarity from volt source to IOEM channel (+) to (+) and (-) to (-)-
see diagram below.
•
Configure 5X00 Eaux systems using AquaManager PC software. Complete
Eaux system configuration information is provided in the AquaManager
Help system.
Analog 0-1 Volt & 0-5 Volt device
CAUTION:
Observe correct polarity on analog input.
