this

manual.

Use of Hazard Information
DANGER: Indicates a potentially or imminently hazardous situation which, if not

avoided, could r esult in death or serious injury.
CAUTION: Indicate s a potentially hazardous situation that may result in minor or

moderate injury.

Note: Information that requires special emphasis.

2.1.1 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.

This symbol, if noted on the product, indicates the need for protective eye wear.

This symbol, when noted on the product, identifies the location of the conne ct ion for Protectiv e Earth
(ground).

This symbol, when noted on the product, identifies the location of a fuse or current limiting device.

2.2 General Product Information

The controller enclosure is NEMA4X/IP66-rated and has a corrosion-resistant
finish designed to withstand corrosive environmental constituents such as salt
spray and hydrogen sulfide. The controller display shows the current reading plus
a secondary measurement such as temperature if connected to a single sensor,
or two readings with their corresponding secon dary measurement reading s when
two sensors are connected.

Installation instructions for the contro ller are presen ted in th is manu al. If a system
with a sensor and a controller has been purchased, complete information for
installation and operation is also presented in the sensor system manual.

Installation

DANGER
The instrument must be installed
by qualified technical per s onn el
for adherence to all applicable
electrical codes.

High-voltage wiring for the controller is conducted behind the high voltage barrier
in the controller enclosure. The barrier must remain in place unless a qualified
installation technician is installing wiring for power, alarms, or relays. See

3-11 for barrier removal information.

3.2.1 Installation in Conduit

In hard-wired electrical applications, the power and safety ground service drops
for the instrument must be 18 to 12 AWG. See
relief and conduit opening sealing plug information. See section 3.2.3 on page 12
for wiring information.

3.2.2 Installation Using a Power Cord

A sealing-type strain relief to maintain the NEMA 4X/IP66 environmental rating
and a power cord less than 3
conductors (including a safety ground wire) can be used, see

on page 21. See Figure 3-12 on page 12 for strain relief and conduit opening

sealing plug assembly. See section 3.2.3 on page 12 for wiring information.

1. Strip ¼-inch of insulation. 2. Seat insulation against connector with no bare wire exposed.

3.2.3 Wiring for Power at the Controller

The instrument can be wired for line power by hard-wiring in conduit or by wiring
to a power cord. Regardless of the type of wire used, t he connections are m ade at
the same terminal. A local disconnect designed to meet local electrical code is
required and must be identified for all types of installation. See

Figure 3-16 on page 14 for suggest ed local disconnect configurations.

1. Obtain appropriate fittings with NEMA 4X/IP66 environmental rating.

2. Loosen the screws using a phillips-head screwdriver and open the hinged

controller cover.

3. Remove the high-voltage barrier (see Figure 3-11 on page 11).

4. Insert the wires through the strain relief fitting or conduit hub located in the

right-rear access hole in the bottom of the enclosure. Tighten the strain relief if
used, to secure the cord.

5. Properly prepare each wire (Figure 3-13) and insert each wire into the
terminal according to Table 3-2. Tug gently after each insertion to ensure the
connection is secure.

6. Seal any unused openings in the controller box with conduit opening sealing

plugs, see

3.3.1 Connecting the Relays

The relay connector accepts 18–12 AWG wire (as determined by load
application). Wire gauge less than 18 AWG is not recommended.

Installation

Hz, 5 amp resistive maximum. See the sensor manual for relay

details.

Danger: Relay loads must be
resistive. User must externally
limit current to the relays to

Amps by use of a fuse or

5
breaker.

Danger: ac power terminals are
designed for single wires. Do not
use more than one wire in each
terminal.

The controller contains three relays designed for use with high voltag e (greater
than 30V-RMS and 42.2V-PEAK or 60
information. The wiring is not designed for low voltage connections. Relay must
not be powered from t he same wiring used to powe r the cont roller . See the sensor
manual for relay setup

The Normally Open (NO) and Common (COM) relay contacts will be connected
when an alarm or other condition is active. The Normally Closed (NC) and
Common relay contacts will be connected when an alarm or other condition
is

inactive or when power is removed from the controller.

3.3.2 Connecting the Analog Outputs

Two isolated analog outputs (1 and 2) are provided, see Figure 3-18. Each out put
can be set to 0–20 or 4–20 mA, and can be assigned to represent the measured
parameter or secondary measurement such as temperature. Make connections
with twisted-pair shielded wire and connect the shield at the controlled component
end or at the control loop end. Do not connect the shield at both ends o f the cab le.
Use of non-shielded cable may result in radio frequency emission or susceptibility
levels higher tha n allowed. Maximum loop resistance is 500 ohm. Refer to the
sensor manual for output software setup.

Make wiring connections at the analyzer end as shown in Figure 3-18.

cables may be purchased to extend the sensor cable length. If the total cable
length exceeds 100 M (300 ft), a termination bo x must be installed. See the

FCC PART 15, Class “A” Limits

Supporting test records by Hewlett Packard, Fort Collins, Colorado Hardware Test
Center (A2LA # 0905-01) and certified compliance by Hach Company.

This 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, and (2) this device must
accept any interfer ence receiv ed, including interf er ence that ma y cause undesired
operation.

Changes or modifications to this unit 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 pr otection against harmful interf erence when th e equipment is
operated in a commercial en vir on men t. This e qu ipme nt ge nerates, 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 of re ducing the interference problems
are applied easily.

1. Disconnect the Model sc100 Controller from its power source to verify that it is
or is not the source of the interference.

2. If the Model sc100 Controller is connected into the same outlet as the device
with which it is interfering, try another outlet.
