The Model 2700 Automation Controller is provided with mounting ears, allowing them
to be easily mounted to a flat surface (for example, an NEMA-rated electrical enclosure)
with four mounting bolts. You should follow the guidelines described in this installation
guide to ensure a successful design.
Mounting Considerations
When selecting a mounting location for the controller, care should be taken to provide
protection against various environmental factors:
•The controller should not be exposed to flying metal chips (be careful during instal-
lation and subsequent machine construction work!), conductive dusts, liquids or
condensing humidity. In environments where these hazards may be present, the
controller should be housed in a NEMA 4 or NEMA 12 rated enclosure, as appropri-
ate.
•The controller is not intended for mounting in an environment requiring explosion-
proof practices.
•If possible, the controller should be mounted physically distant from devices produc-
ing Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI).
This includes motor starters, relays, large power transformers, ultrasonic welding
apparatus, etc.

4Model 2700 Controller Installation Guide
Inserting Modules into the Controller
The Model 2700 controller accepts a variety of plug-in modules. You insert the modules
into one of the slots of your Model 2700 controller. Any combination of modules,
subject to system limits, may be inserted into the controller. The plug-in CPU has its
own slot and is not counted as part of the total number of slots in a controller.
You may insert modules in any order; the controller’s CPU dynamically assigns motor
number, input number, output numbers, etc., each time power is reapplied to the control-
ler. These numbers are assigned from left to right across the controller, from slot one to
slot ten in a Model 2700-10.
To install a module into the controller:
1. Remove all AC and DC power to the controller. This includes any external power
supplies connected to the controller.
2. Remove the retaining screws from the top and bottom of the cover plate at the
location where you are inserting the new module. Save these screws to reinstall the
new module.
3. To orient the module properly, make sure the labeling on the module reads right-side
up. See illustration on page 2.
4. Slide the module into the slot, insuring that the circuit board slides into the nylon
guides at the top and bottom of the slot.
5. Press the module firmly into the controller. When properly seated, the faceplate of
the module is flush with the adjacent sheet metal surface.
6. Reinstall the retaining screws in the top and bottom of the new module.
7. Wire the module according to the instructions in its installation guide.

Some modules provide one or more connectors on their faceplates. To keep their wires
from becoming accidently unplugged and from tangling together, CTC manufactures a
bracket to hold the wires. The Model 2699 bracket attaches to the controller as shown
below. Once the bracket is installed, you can attach connector wires to it.
1. Remove the retaining screws from the top of the module. Save these screws to
secure the bracket.
2. Place the bracket on the controller, making sure you line up the holes on the bracket
with the holes for the retaining screws.
3. Reinstall the retaining screws.
4. Wire the module according to the instructions in its installation guide.
5. Use tywraps to fasten the wires to the holes in the bracket.

6Model 2700 Controller Installation Guide
Connecting AC Power
The Model 2700 contains an internal power supply which provides two mutually-
isolated voltages (+5 VDC and +24 VDC) for the operation of the controller. Also
included are two LED indicators located on the CPU for these voltages and a power ON-
OFF switch.
The controller’s power supply requires AC power, either 120 VDC or 240 VAC nominal
for proper operation. Power is applied to the controller via the standard IEC-type power
connector on the side of the controller. A US-standard three-prong power cord is pro-
vided with the controller for this purpose.
The supply voltage required is determined by a voltage selector on the side of the unit
(see diagram below). A fuse of the appropriate rating must also be installed in the fuse
holder integral to the IEC-type connector.
Voltage Range Fuse
120 VAC 110 - 132 2Amp
240 VAC 210 - 264 1Amp
The following illustrations show the location of the voltage selector/fuse holder. The
voltage selector/fuse holder are in a removable cartridge. To remove the voltage
selector/fuse holder, insert a small flat head screwdriver into the slot and push the
cartridge out. You need to remove the voltage selector/fuse holder from the controller, to
change the voltage selection and to insert a fuse. The fuse holders are located along the
side of the cartridge.

Using Step-down or Isolation Transformers
When using a step-down or isolation transformer to supply power to the controller, be
aware of the following potential issues, all of which are drawn from experience:
•Step-down transformers are typically derive 120 VAC from much higher voltage
lines that are also being used to power heavy equipment. Often, when motors are
first energized in heavy equipment, the stall currents that result can cause the voltage
supplied to the step-down transformer to drop by as much as 50%. Because step-
down transformers are ratio-metric devices, the voltage supplied to the controller
drops proportionately, causing a potential system malfunction.
•The relatively light load imposed by the controller on the transformer secondary may
result in excessive voltage being present, representing a potential hazard to the
system.
•Neither type of transformer represents ideal protection against electrical noise.
Inter-winding capacitances can result in noise transference among windings, and
differential noise may still be electromagnetically coupled to the secondary.
•Adequate grounding of the controller is still critical to its proper performance. For
more information, see the section on The Importance of Proper Grounding.
These issues often point to the use of an independent power feed (120 or 240 VAC) for
the controller and associated components. The resulting additional stability and design
integrity are often well worth the slight additional cost.
The Importance of Proper Grounding
The controller is outfitted with an integral line filter to protect against electrical noise
carried on the AC power line. This line filter, along with the shielding provided by the
controller enclosure itself, depend on the presence of a good ground connection for
effectiveness. This is normally accomplished by connecting the controller’s power cord
to a well-grounded outlet.
As with any electronic equipment, the controller’s ground should follow a direct, low-
impedance path to the plant’s power source. If possible, this path should not be shared
by any machinery which injects a large amount of electrical noise into the ground.
In instances where step-down or isolation transformers are being used to power the
controller, the ground connection should still be made directly to the controller.
For further consideration regarding noise protection, refer to the Application Note,
Reducing Noise Susceptibility. Application notes may be obtained at no charge from
your distributor or directly from CTC.
The Controller’s Power System
The controller’s power system provides two operating voltages, electrically isolated
from one another:
•+5 VDC: Powers the controller’s internal circuitry, including the CPU and the
logic-level circuitry on the various modules.
•+24 VDC: Available with a current capacity of up to 1.5 Amp (maxium), to power
external control devices, such as solenoid valves, relays, sensors. You can also use
this power supply with some modules to power circuitry on the outbound side of any
on-board isolation.
The +5 V supply is not usually made available at any of the module connectors.
NOTE: Do not make any external connections to either the +5 V power supply or its common, as an
increased susceptibility to electrical noise may result.

8Model 2700 Controller Installation Guide
Using External Power Supplies
Many of the modules available for this series of controllers allow the use of an external
power supply for powering actuators and other devices, in place of using the controller’s
+24 V supply. The individual installation guides for these modules provide additional
details in this regard.

It is possible to connect an external +24 V power supply (with a capacity not in excess
of 10 Amp) to the controller’s backplane, taking the place of the controller’s internal +24
V supply. A nylon 3-pin connector is provided on the side of the controller for this
purpose. This connector, as supplied by CTC, is fitted with a mating plug wired with a
jumper. The jumper carries +24 V from the internal power supply to the I/O power bus
extending across the controller’s backplane.
If you remove the jumper plug, you may use the connector to attach an external power
supply to the I/O power bus and to the I/O common, pins 1 and 3. An extra mating
connector with pins is included with each controller, or you can order a plug with a
pigtail wires (Model 2885) from CTC for this purpose.
WARNING: Do not connect an external supply with a voltage rating other than +24 V to this connec-
tor, as potential incompatibilities may exist with the modules installed in the controller.
Consult CTC for further information.

Status Light Description
The status light on the Model 2700 can indicate one of the following conditions:
•Software fault: A periodic flashing light on the 2701E CPU indicates a program
software fault. This means the controller was unable to execute due to an applica-
tion problem within the program. To determine what type of software fault has
occurred, you can view the program status using Quickstep for Windows’ program
monitoring utility, CTCMON.
If a program software fault occurs, the controller is idle and all setable resources,
such as outputs, registers or flags, are left in the state they were in prior to the
software fault. You can program register 13009 to turn off a specific output in the
event of a software fault. Refer to the list of special purpose registers for more
information.
•Hardware fault: A steady red light indicates that the internal watch dog timer has
disabled the controller’s CPU. If this occurs, the controller’s outputs are also
disabled. Try cycling the power, re-downloading your Quickstep program, or both.
If the fault continues, your controller may have to be returned to Control Technology
Corp. for repair. For further details, contact our Technical Support department
before returning your controller.
When powering-up the controller, the status light is a steady red light during the first
second of operation.

10 Model 2700 Controller Installation Guide
Your controller can be set up to communicate with a computer or with other controllers
through an RS-232 port or on an Ethernet network.
Using the RS-232 Port for Controller Communications
The RS-232 port on your Model 2700 controller provides a means for both programming
and data communications via a personal computer using Quickstep. The controller is
also equipped with a built-in protocol allowing direct computer communications with the
controller’s RS-232 port. This protocol is described in the Guide to CTC Serial Data
Communications. It allows an external computer to directly interact with many of the
controller’s resources such as, counters, registers, I/O, flags, without modifying the
controller’s program.
You can also use RS-232 communications when monitoring a controller using
CTCMON.
RS-232 Connections
Connections to the controller’s RS-232 port is made via a
modular jack on the controller (labelled COMM). This jack
carries the receive signal, two commons (ground), and the
transmit signal for the communications channel. The pin
connection diagram illustrates the wiring of the jack. Only the
center four connectors of a six- or eight-conductor jack are used.
A series of standard CTC cables are available for making
connections to this jack. See the illustrations below and on the
following page. As an alternative, many commonly-available
telephone cables may be substituted.
NOTE: Do not connect the controller to a telephone line.
Connecting to a D Connector
RS-232 ports on computers are frequently brought out through 25- or 9-pin D type
connectors. There is a standard for wring such connectors followed by most PC
manufacturers.
