Please read this entire manual before unpacking, setting up or operating this equipment. Pay
attention to all danger and caution statements. Failure to do so could result in serious injury to the
operator or damage to the equipment.
Make sure that the protection provided by this equipment is not impaired. Do not use or install this
equipment in any manner other than that specified in this manual.
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.
CAUTION
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. A symbol on the instrument is referenced in the manual with a
precautionary statement.
This symbol, if noted on the instrument, references the instruction manual for operation and/or safety
information.
This symbol indicates that a risk of electrical shock and/or electrocution exists.
This symbol indicates the presence of devices sensitive to Electro-static Discharge (ESD) and
indicates that care must be taken to prevent damage with the equipment.
Electrical equipment marked with this symbol may not be disposed of in European domestic or public
disposal systems. Return old or end-of-life equipment to the manufacturer for disposal at no charge to
the user.
Certification
Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A:
4 English
Supporting test records reside with the manufacturer.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne
sur les équipements provoquant des interférences.
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 conditions:
1. The equipment may not cause harmful interference.
2. The equipment 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.
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 their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment 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.

2 Strain relief assembly (optional depending on
controller version)
5 High-voltage barrier
3 Digital connection fitting (optional depending on
controller version)
6 Sensor modules (optional)
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
The controller has four configurable relay switches and two analog outputs. An optional analog
output module can increase the number of analog outputs to five.
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. Refer to Connect a digital sc sensor on page 20 for instructions
about how to scan for devices when the controller is already powered on.
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.
Note: Units that have the Underwriters Laboratories (UL) certification are intended for indoor use only and do not
have a NEMA 4X/IP66 rating.
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
CAUTION
Personal injury hazard. Only qualified personnel should conduct the tasks described in this section of the manual.
The controller can be installed on a surface, panel or pipe (horizontal or vertical). For mounting
options and instructions, refer to Figure 2, Figure 3 on page 8, Figure 4 on page 9, Figure 5
on page 10 and Figure 6 on page 11.
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 5 on page 10.
