Use of hazard information
D A N G E R
Indicates a potentially or imminently hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING
Indicates a potentially or imminently hazardous situation which, if not avoided,
could result in death or serious injury.
C A U T I O N
Indicates a potentially hazardous situation that may result in minor or moderate
injury.
N O T I C E
Indicates a situation which, if not avoided, may cause damage to the instrument.
Information that requires special emphasis.
Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or
damage to the instrument could occur if not observed.
This symbol, if noted on the instrument, references the instruction
manual for operation and/or safety information.
This symbol, when noted on a product enclosure or barrier, indicates
that a risk of electrical shock and/or electrocution exists.
Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
Electrical equipment marked with this symbol may not be disposed of
in European public disposal systems after 12 August of 2005. In
conformity with European local and national regulations (EU Directive
2002/98/EC), European electrical equipment users must now return old
or end-of-life equipment to the Producer for disposal at no charge to
the user.
Note: For return for recycling, please contact the equipment producer or supplier
for instructions on how to return end-of-life equipment, producer-supplied electrical
accessories, and all auxillary items for proper disposal.
Hach certification of compliance
Canadian interference-causing equipment regulation, IECS-003,
Class A
Supporting test records reside with the manufacturer. This Class A digital
apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations. Cet appareil numèrique de la classe A respecte
toutes les exigences du Rëglement sur le matÈriel brouilleur du Canada.
FCC Part 15, Class "A" Limits
Supporting test records reside with the manufacturer. The device complies
with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including
interference that may cause undesired operation.
Changes or modifications to this equipment not expressly approved by the
party responsible for compliance could void the user's authority to operate
the equipment. This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
4 English
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely
to cause harmful interference, in which case the user will be required to
correct the interference at his own expense. The following techniques can
be used to reduce interference problems:
1. Disconnect the unit from its power source to verify that it is or is not the
source of the interference.
2. If the equipment is connected to the same outlet as the device
experiencing interference, connect the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the
interference.
5. Try combinations of the above.
Product overview
The controller displays sensor measurements and other data, can transmit
analog and digital signals, and can interact with and control other devices
through outputs and relays. Outputs, relays, sensors and sensor modules
are configured and calibrated through the user interface on the front of the
controller.
Figure 1 shows the product components. Components may vary according
to controller configuration. Contact the manufacturer if parts are damaged
or missing.

Sensors and sensor modules
The controller accepts up to a maximum of two sensor modules or two
digital sensors (depending on the controller configuration), along with one
communication module. A single digital sensor and a single sensor module
can be installed in combination. A variety of sensors can be wired to the
sensor modules. Sensor wiring information is given in the specific sensor
manuals and in the user instructions for specific modules.
Relays, outputs and signals
English 5
The controller has four configurable relay switches and two analog
outputs. An optional analog output module can increase the number of
analog outputs to six.
Device scans
With two exceptions, the controller automatically scans for connected
devices without user input when it is powered on. The first exception is
when the controller is powered on for the first time before initial use. The
second exception is after the controller configuration settings have been
set to their default values and the controller is powered on. In both cases,
the controller first displays the language, date and time edit screens. After
the language, date and time entries are accepted, the controller performs
a device scan after the language, date and time entries are accepted.
Controller enclosure
The controller enclosure is NEMA 4X/IP66-rated and has a corrosion-
resistant finish designed to withstand corrosive environmental
constituents such as salt spray and hydrogen sulfide. Protection against
environmental damage is strongly recommended for outdoor use.
Controller mounting options
The controller can be mounted to a panel, to a wall or to a vertical or
horizontal pipe. A neoprene sealing gasket is included and can be used to
reduce vibration. The gasket can be used as a template for panel mounting
before the inner gasket component is separated.
Installation
Mounting components and dimensions
C A U T I O N
Personal injury hazard. Only qualified personnel should conduct the tasks
described in this section of the manual.
For mounting options and instructions, refer to Figure 2, Figure 3,
Figure 4 on page 7, Figure 5 on page 8 and Figure 6 on page 8.
The controller can be mounted to a vertical pipe (Figure 6 on page 8)
or a horizontal pipe (not shown).
For horizontal pipe mounts, the mounting feet (Figure 2) must be attached
to the mounting bracket in a vertical position.
For both horizontal and vertical pipe mounts, attach the mounting bracket
to the controller as shown in Figure 6 on page 8.

High-voltage barrier
High-voltage wiring for the controller is located behind the high-voltage
barrier in the controller enclosure. The barrier must remain in place except
when installing modules or when a qualified installation technician is wiring
