1/01 UDC3300 Limit Controller Product Manual 1
Section 1 –Overview
1.1 Introduction
Function The UDC3300 Universal Digital Limit Controller is a microprocessor-
based stand-alone controller. It combines the highest degree of
functionality and operating simplicity offered in a 1/4 DIN size controller.
With a typical accuracy of ±0.20% of span, the UDC3300 is an ideal
controller for limiting temperature and other process variables in
numerous heating and cooling applications, in metal working, food, and
pharmaceuticals, and testing and environmental work.
Easy to read displays The dedicated vacuum fluorescent displays with English prompts make
the operator interface easy to read, understand and operate.
Programmed sequences of displays assure quick and accurate entry of all
configurable parameters.
Easy to operate Simple keystrokes let you select input and range configuration, set the
operating parameters that meet your process control needs now, and
change them later to meet new ones.
The tactile keyboard provides positive operator feedback. Self diagnostics,
fault tolerant design and keyboard security provide maximum assurance of
trouble-free operation.
Latching relays This limit controller has a latching output relay which is de-energized
whenever the PV goes above (high limit) or below (low limit) a selected
setpoint value. When the limit is exceeded (high or low), the lower display
alternately indicates “the limit control setpoint value” and the word
“limit.”
Reset of relay Reset of the latching output relay is made through a [RESET] key on the
front of the controller or an external switch (if the option is present).
Alarm relay Two additional non-latching alarm relays with two setpoints each alert
you to critical process conditions.

1.1 Introduction, Continued
Mount anywhere The UDC is industrial control equipment that must be panel mounted.
The wiring terminals must be enclosed within the panel. The UDC is
environmentally hardened and, when suitably enclosed, can be mounted
virtually anywhere in plant or factory; on the wall, in a panel, or even on
the process machine. It withstands ambient temperatures up to 55 °C
(133 °F) and resists the effects of vibration and mechanical shock.
CE Conformity
(Europe) This product is in conformity with the protection requirements of the
following European Council Directives: 73/23/EEC, the Low Voltage
Directive, and 89/336/EEC, the EMC Directive. Conformity of this
product with any other “CE Mark”Directive(s) shall not be assumed.
Deviation from the installation conditions specified in this manual, and the
special conditions for CE conformity in Section 2.1, may invalidate this
product’s conformity with the Low Voltage and EMC Directives.
ATTENTION
The emission limits of EN 50081-2 are designed to provide reasonable protection against harmful
interference when this equipment is operated in an industrial environment. Operation of this equipment
in a residential area may cause harmful interference. This equipment generates, uses, and can radiate
radio frequency energy and may cause interference to radio and television reception when the
equipment is used closer than 30 meters (98 feet) to the antenna(e). In special cases, when highly
susceptible apparatus is used in close proximity, the user may have to employ additional mitigating
measures to further reduce the electromagnetic emissions of this equipment.

Function of keys Table 1-1 shows each key on the operator interface and defines its
function.
Table 1-1 Function of Keys
Key Function
SET UP •Places the controller in the Configuration Set Up group select
mode. Sequentially displays Set Up groups and allows the
[FUNCTION] key to display individual functions in each Set Up
group.
FUNCTION •Used in conjunction with the [SET UP] key to select the individual
functions of a selected Configuration Set Up group.
•Used during field calibration procedure.
LOWER
DISPLAY
•Selects one of the following display modes when no limit
conditions exist:
#1 Upper Display = the value of the process variable
Lower Display = the value of the Limit Control Setpoint
#2 Upper Display = (blank) except during Limit conditions
Lower Display = the value of the Limit Control Setpoint
#3 Upper Display = (blank)except during Limit conditions
Lower Display = LIMIT OK
•Pressing [LOWER DISPLAY] key while a limit condition exists,
shows the following in the lower display:
TIME XX.YY = Limit action duration in hours and minutes
PK_XXXXX = Peak PV Value—The highest PV value reached for
a High Limit Controller, or the lowest PV value
reached for a Low Limit Controller.
RESET •Resets the latching output relay. Relay cannot be reset while a
limit condition exists.
The upper blank key is not used.
The lower blank key restores an original value.
–When you are using the [FUNCTION] key and [s] [t] keys to
change a parameter value of selection and you decide you want
to keep the original value that was displayed, press the lower
blank key, before entry, to recall the original value.
•Increases the setpoint, output, or configuration values displayed.
•Decreases the setpoint, output, or configuration values displayed.

•Carefully slide the chassis assembly into the case, press to close and
tighten the screw. Replace the screw cover.

10 UDC3300 Limit Controller Product Manual 1/01
2.4 Wiring
Electrical
considerations The controller is considered “rack and panel mounted equipment”per
EN 61010-1, Safety Requirements for Electrical Equipment for
Measurement, Control, and Laboratory Use, Part 1: General
Requirements. Conformity with 72/23/EEC, the Low Voltage Directive
requires the user to provide adequate protection against a shock hazard.
The user shall install this controller in an enclosure that limits
OPERATOR access to the rear terminals.
Controller grounding PROTECTIVE BONDING (grounding) of this controller and the
enclosure in which it is installed shall be in accordance with National and
local electrical codes. To minimize electrical noise and transients that may
adversely affect the system, supplementary bonding of the controller
enclosure to a local ground, using a No. 12 (4 mm2) copper conductor, is
recommended.
Taking electrical noise
precautions Electrical noise is composed of unabated electrical signals which produce
undesirable effects in measurements and control circuits.
Digital equipment is especially sensitive to the effects of electrical noise.
Your controller has built-in circuits to reduce the effect of electrical noise
from various sources. If there is a need to further reduce these effects:
•Separate External Wiring - separate connecting wires into bundles
(see Table 2-2) and route the individual bundles through separate
conduits or metal trays.
•Use Suppression Devices - for additional noise protection, you may
want to add suppression devices at the external source. Appropriate
suppression devices are commercially available.
NOTE For additional noise information, refer to Section 9.
Permissible wire
bundling Table 2-2 shows which wire functions should be bundled together.
NOTE For installation where high EMI/RFI noise cannot be avoided, we
recommend you use shielded twisted pair wires for the signals in bundle 2.
