PRODUCT WARRANTY
Analytical Technology, Inc. (Manufacturer) warrants to the Customer that if any
part(s) of the Manufacturer's products proves to be defective in materials or
workmanship within the earlier of 18 months of the date of shipment or 12 months of the
date of start-up, such defective parts will be repaired or replaced free of charge.
Inspection and repairs to products thought to be defective within the warranty period will
be completed at the Manufacturer's facilities in Oaks, PA. Products on which warranty
repairs are required shall be shipped freight prepaid to the Manufacturer. The
product(s) will be returned freight prepaid and allowed if it is determined by the
manufacturer that the part(s) failed due to defective materials or workmanship.
This warranty does not cover consumable items, batteries, or wear items subject
to periodic replacement including lamps and fuses.
Gas sensors, except oxygen sensors, are covered by this warranty, but are
subject to inspection for evidence of extended exposure to excessive gas
concentrations. Should inspection indicate that sensors have been expended rather
than failed prematurely, the warranty shall not apply.
The Manufacturer assumes no liability for consequential damages of any kind,
and the buyer by acceptance of this equipment will assume all liability for the
consequences of its use or misuse by the Customer, his employees, or others. A defect
within the meaning of this warranty is any part of any piece of a Manufacturer's product
which shall, when such part is capable of being renewed, repaired, or replaced, operate
to condemn such piece of equipment.
This warranty is in lieu of all other warranties (including without limiting the
generality of the foregoing warranties of merchantability and fitness for a particular
purpose), guarantees, obligations or liabilities expressed or implied by the Manufacturer
or its representatives and by statute or rule of law.
This warranty is void if the Manufacturer's product(s) has been subject to misuse
or abuse, or has not been operated or stored in accordance with instructions or if the
serial number has been removed.
Analytical Technology, Inc. makes no other warranty expressed or implied except
as stated above.

Safety
Analytical Technology has made every effort to ensure the reliability and safety of
the C14 Scanner and to recommended safe uses in systems applications. Note
that in any application failures can occur.
Good engineering practices, electrical codes, and insurance regulations require
that you use independent external safety devices to prevent potentially
dangerous or unsafe conditions. Assume that the scanner can fail or that other
unexpected conditions can occur.
For additional process safety, program process control computer, to
automatically reload your desired operating parameters after a power failure.
This safety feature however does not eliminate the need for other external,
independent safety devices in dangerous conditions.
Analytical Technology also includes ANASCAN, software package for IBM-
compatible computers. In the event of a Scanner reset, ANASCAN will reload the
Scanner with the current values in computer memory. The user must ensure that
this reset will be safe for the process. Again, use of ANASCAN does not
eliminate the need for appropriate external, independent safety devices.
Contact Analytical Technology immediately if you have any questions about
system safety of system operation.
WARNING
The Scanner should never be used as a safety shutdown device. It
should only be used with other approved independent safety shutdown
devices.

Introduction
The C14 Scanner is a modular monitoring system with 16 fully independent
inputs. It can function as a stand-alone system. The Scanner front panel has a
Liquid Crystal Display (LCD) and touch keypad for local display and local
parameter entry. You can also use it as the key element in a computer
supervised data acquisition system; the Scanner can be locally or remotely
controlled via an RS-485 serial communications interface, or over telephone lines
by modem.
Features Include:
Automatic Scaling for Linear Analog Inputs: The Scanner automatically
scales linear inputs used with other industrial process sensors. Simply enter two
measurement points. For example, to scale a gas sensor enter the endpoints:
Low PV is 0 PPM. While High PV is 100 PPM. All other values for that channel
will automatically be in PPM.
Flexible Alarm Outputs: Independently set alarms for each channel. Alarms can
activate an output by themselves, or they can be grouped with other alarms to
activate an output.
Alarm Outputs: You can specify alarm setpoints to operate outputs as latched
or unlatched functions.
Global Alarm: When any alarm is triggered, the Global Alarm Output is also
triggered, and it stays on until you acknowledge it.
System Fault: The Scanner system fault output notifies you of microprocessor
failure. Use it to hold a relay closed while the system is running, so it notifies you
of scanner failure.
AC Fail: If the battery backup option is installed, “AC FAIL” led lights to indicate
power has failed, and the Scanner is operating on battery backup.
Front Panel or Computer Operation: Set up and run the Scanner from the front
panel; or from a local or remote computer. Analytical Technology includes
ANASCAN software you can use to operate the Scanner. ANASCAN has these
features:
• Process Overviews
• Parameter Setup
• Graphic Trend Plotting
• Data Logging
Multiple Job Storage: Store up to 8 Jobs in protected memory, and access
them locally by entering a single job number or remotely via digital inputs. Each
job has a set of alarm conditions.

Installation
This chapter describes how to install the Scanner. Installation of the Scanner
involves the following procedures:
• Determining the best location for the Scanner
• Mounting the Scanner
• Power Connection
• Input Wiring
• Communications Wiring (RS-485)
• Output Wiring
Safety
Analytical Technology has made every effort to ensure the reliability and safety of
this product. In addition, we have provided recommendations that will allow you
to safely install and maintain the Scanner.
External Safety Devices
External safety devices should be used to prevent potentially dangerous and
unsafe conditions upon equipment failure. Always assume that this device can
fail with outputs full on. or full off, by the occurrence of an unexpected external
condition.
DANGER
Ensure that power has been shut off to your entire process before you begin
installation of the Scanner.
WARNING
In any application, failures can occur. These failures can result in the
occurrence of output failures, which can cause damage to the Scanner, or
to the equipment or process connected to the Scanner. Therefore, always
follow good engineering practices, electrical codes, and insurance
regulations when installing and operating this equipment.

RS-485 Interface
You can communicate with up to 32 Scanners on a single common loop.
Wire equipment in a single “daisy chain” using twisted shielded pairs for the RS-
485 cables. Don’t use “octopus”, or “spurs”, or “star” patterns.
Use the internal 200 Ohm terminating resistor on the RX line of the last Scanner
in the system. (If you have only one scanner, it is the last scanner in the system).
Use jumper JU1 to select the terminating resistor; place it in B position for
termination and A position for non-termination.
Connect the shields to earth ground only at the computer or other R485 interface.
Do not connect the shield to the Scanner.
NOTE
If you connect RS-485 communications and they do not function
properly, or if you have measurement problems when
communications lines are connected, request additional technical
information from our Technical Service Department.
