Introduction

10/00 UDC2300 Limit Controller Product Manual 1

1 Introduction

1.1 Overview

Introduction

UDC2300 Limit Controllers accept input signals from any of several types of externalsensors such as Thermocouples (T/Cs) and Resistance Temperature Detectors (RTDs). Itconditions these signals, as necessary, to derive the equivalent Process Variable (PV)value that drives various circuits in the controller.

The equivalent PV signal is compared with the Limit control set point and any errorsignal from the differential amplifier de-energizes the coil of an electromechanical,single-pole, single-throw (SPST) limit output relay.

When de-energized, the output relay “Locks Out” and remains that way until the PV inputsignal drops below the High Limit Set Point or goes above the Low Limit Set Point andthe controller is reset manually via the keyboard or from a remote location (Contact InputOption).

You can select normally open (N.O.) or normally closed (N.C.) Limit Relay Contactssimply by moving a jumper.

The contact of the output relay terminates at the rear terminal of the controller to whichyou make the appropriate field wiring connections.

A flashing “LIMIT” in the lower display indicates that the output relay is de-energized.

High Limit Controller

When the PV input signal is below the limit set point, the output relay energizes. If thePV signal exceeds the limit set point, the output relay de-energizes and the flashing“LIMIT” display is turned on.

When the PV signal returns to a value below the limit set point, the controller can be resetmanually using the MAN-AUTO RESET key or Contact Input Option.

Low Limit Controller

When the PV input signal is above the limit set point, the output relay energizes. If thePV signal falls below the limit set point, the output relay de-energizes and the flashing“LIMIT” display is turned on.

When the PV signal returns to a value above the limit set point, the controller can be resetmanually using the MAN-AUTO RESET key or Contact Input Option.

2.6 Wiring

Electrical Considerations

The controller is considered “rack and panel mounted equipment” per EN61010-1, SafetyRequirements for Electrical Equipment for Measurement, Control, and Laboratory Use, Part1: General Requirements. Conformity with 72/23/EEC, the Low Voltage Directive requiresthe user to provide adequate protection against a shock hazard. The user shall install thiscontroller in an enclosure that limits OPERATOR access to the rear terminals.

Mains Power Supply

This equipment is suitable for connection to 90 Vac to 264 Vac, 50/60 Hz, power supplymains. It is the user’s responsibility to provide a switch and non-time delay (NorthAmerica), quick-acting, high breaking capacity, Type F (Europe), 1/2A, 250V fuse(s), orcircuit-breaker, as part of the installation. The switch or circuit breaker shall be located inclose proximity to the controller, within easy reach of the OPERATOR. The switch orcircuit breaker shall be marked as the disconnecting device for the controller.

Controller Grounding

PROTECTIVE BONDING (grounding) of this controller and the enclosure in which it isinstalled shall be in accordance with National and Local electrical codes. To minimizeelectrical noise and transients that may adversely affect the system, supplementarybonding of the controller enclosure to a local ground, using a No. 12 (4 mm2) copperconductor, is recommended.

Control/Alarm Circuit Wiring

The insulation of wires connected to the Control/Alarm terminals shall be rated for thehighest voltage involved. Extra Low Voltage (ELV) wiring (input, current output, andlow voltage Control/Alarm circuits) shall be separated from HAZARDOUS LIVE (>30Vac, 42.4 Vpeak, or 60 Vdc) wiring per Permissible Wiring Bundling, Table 2-6.

Electrical Noise Precautions

Electrical noise is composed of unabated electrical signals, which produce undesirableeffects in measurements and control circuits.

Digital equipment is especially sensitive to the effects of electrical noise. Your controllerhas built-in circuits to reduce the effect of electrical noise from various sources. If there isa need to further reduce these effects:

• Separate External Wiring—Separate connecting wires into bundles(See Permissible Wiring Bundling - Table 2-6) and route the individual bundlesthrough separate conduit metal trays.Use Suppression Devices—For additional noise protection, you may want to addsuppression devices at the external source. Appropriate suppression devices arecommercially available.

For additional noise information, refer to Document #51-52-05-01, How to Apply Digital Instrumentation inSevere Electrical Noise Environments.

4.1 Overview

Introduction

Configuration is a dedicated operation where you use straightforward keystrokesequences to select and establish (configure) pertinent control data best suited for yourapplication.

To assist you in the configuration process, there are prompts that appear in the upper andlower displays. These prompts let you know what group of configuration data (Set Upprompts) you are working with and also, the specific parameters (Function prompts)associated with each group.

Figure 3-1 shows you an overview of the prompt hierarchy as they appear in thecontroller.

As you will see, the configuration data is divided into 5 main Set Up groups plus promptsfor calibration and prompts that show the status of the continuous background tests thatare being performed

4.3 Configuration Procedure

IntroductionEach of the Set Up groups and their functions are pre-configured at the factory.The factory settings are shown in Table 4-3 through Table 4-8 that follow this procedure.

If you want to change any of these selections or values, follow the procedure in Table 4-2.This procedure tells you the keys to press to get to any Set Up group and any associatedFunction parameter prompt.

Procedure

The prompting scrolls at a rate of 2/3 seconds when the [SET UP] or [FUNCTION] key is held in.Also, [] [] keys will move group prompts forward or backward at a rate twice as fast.

Table 4-2 Configuration ProcedureStep Operation Press Result

1 Enter Set UpMode

SET UP Upper Display = SET

Lower Display = LOCK (This is the first Set Up Group title)

2 Select any Set UpGroup

SET UP Sequentially displays the other Set Up group titles shown inthe prompt hierarchy in Table 4-1.You can also use the [] [] keys to scan the Set Up groupsin both directions. Stop at the Set Up group title thatdescribes the group of parameters you want to configure.Then proceed to the next step.

3 Select a FunctionParameter

FUNCTION Upper Display = the current value or selection for the firstfunction prompt of the selected Set Upgroup.

Lower Display = the first Function prompt within that Set Upgroup.

Sequentially displays the other function prompts of the SetUp group you have selected. Stop at the function prompt thatyou want to change, then proceed to the next step.

4 Change theValue orSelection

[] [] Increments or decrements the value or selection thatappears for the selected function prompt. If you change thevalue or selection of a parameter while in Set Up mode thendecide not to enter it, press [MAN-AUTO/RESET] once—theoriginal value or selection is recalled.

5 Enter the Valueor Selection

FUNCTION Enters value or selection made into memory after anotherkey is pressed.

6 Exit Configuration DISPLAY Exits configuration mode and returns controller to the samestate it was in immediately preceding entry into the Set Upmode. It stores any changes you have made.If you do not press any keys for 30 seconds, the controllertimes out and reverts to the mode and display used prior toentry into Set Up mode.

4.9 Alarms Set Up Group

Introduction

An alarm is an indication that an event that you have configured (for example—ProcessVariable) has exceeded one or more alarm limits. There are two alarms available. Eachalarm has two setpoints. You can configure each of these two setpoints to alarm onvarious controller parameters.

There are two alarm output selections, High and Low. You can configure each setpoint toalarm either High or Low. These are called single alarms.

You can also configure the two setpoints to alarm on the same event and to alarm bothhigh and low. A single adjustable Hysteresis of 0 to 100% is configurable for the alarmsetpoint.

See Table 2-4 in the Installation section for Alarm relay contact information.The prompts for the Alarm Outputs appear whether or not the alarm relays are physicallypresent. This allows the Alarm status to be shown on the display and/or sent viacommunications to a host computer.

5.3 Entering a Security Code

Introduction

The level of keyboard lockout may be changed in the Set Up mode. However, knowledgeof a security code number (0 to 4095) may be required to change from one level oflockout to another. When a controller leaves the factory, it has a security code of 0, whichpermits changing from one lockout level to another without entering any other codenumber.

Procedure

If you require the use of a security code, select a number from 0001 to 4095 and enter itwhen the lockout level is configured as NONE. Thereafter, that selected number must beused to change the lockout level from something other than NONE.

Write the number on the Configuration Record Sheet in the configuration section so you will have apermanent record.

5.4 Lockout Feature

Introduction

The lockout feature in the UDC2300 is used to inhibit changes (via keyboard) of certainfunctions or parameters by unauthorized personnel.

Lockout levels

There are different levels of Lockout depending on the level of security required. Theselevels are:

• NONE No Lockout. All groups Read/Write.

• CAL All groups Read/Write except Calibration

• CONF Configuration parameters are Read only. No writes permitted.Calibration Group is not available.

• +SP Only the Lockout group is available for Read/Write.Setpoint value is Read Only.

See Subsection 4.4- Lockout Parameters Set Up Group prompts to select one of theabove.

Key error

When a key is pressed and the prompt “Key Error” appears in the lower display, it will befor one of the following reasons:

• Parameter not available or locked out• Not in setup mode, press [SET UP] key first

Operation


5.5 Monitoring Your Limit Controller

Annunciators

The following annunciator functions have been provided to help monitor the controller:

Table 5-2 Annunciators

Annunciator Indication

ALM 1 2 A visual indication of each alarmBlinking 1 indicates alarm latched and needs to be acknowledgedbefore extinguishing when the alarm condition ends

F or C A visual indication of the temperature unitsF—Degrees FahrenheitC—Degrees Celsius

Display Mode

The displays and indicators on the operator interface, as shown in Figure 5-1, let you seewhat is happening to your process and how the Limit Controller is responding.

The Limit Controller is a single line display device except when in the SETUP mode orthe [DISPLAY] key is pressed or limit has been reached.

This display can be one of two types:

Display Mode 1

The PV is displayed in the upper display and the lower display is blank.

Display Mode 2

The setpoint is displayed in the upper display and “SP” is displayed inthe lower display.

Viewing the operating parameters

Press the [DISPLAY] key to scroll through the operating parameters:SP* Setpoint

PV Process Variable* You can press or to change the value of this parameter.

Timing out from lower display

The normal variable display will automatically return in the upper display if the[DISPLAY] key is not pressed for 30 seconds.

Operation


Diagnostic Error Messages

The UDC2300 performs background tests to verify data and memory integrity. If there is amalfunction, an error message will be displayed. In the case of more than onesimultaneous malfunction, the messages will be displayed sequentially on the lowerdisplay. If any of these error messages in Table 5-3 occur, refer to Section 7 -Troubleshooting for information to correct the failure.

High and Low Limit Indication

When the high or low limit is exceeded, the lower display indicates the word “LIMIT”(blinking). The PV is indicated in the upper display. This will continue until the Out-of-Limit condition exists and you reset the latching relay using the [MAN-AUTO RESET] keyor through the Optional External Reset feature.

The Limit Relay cannot be reset while a Limit condition exists.

Operation


5.6 Operating Your Limit Controller

Operating Principles

The Limit Controller accepts signals from such sources as Thermocouples (T/Cs),Resistance Temperature Detectors (RTDs), and Radiamatics. The equivalent PV signal iscompared with the Limit set point. If above (Hi Limit) or below (Lo Limit), a limit outputrelay is de-energized. When de-energized, the output relay locks out and remains in thisstate until the PV input signal drops below the high limit setpoint or rises above the lowlimit setpoint, and the controller is reset manually from the front of the controller orthrough an optional external switch.

Check the configuration

Make sure the Limit Controller has been configured to handle your process needs. Referto Section 4 - Configuration for prompts and parameters.

• Input Parameters

• Alarm Set Points and type

• Limit Control Type - high or low

• External Reset (Contact Input) - enable or disable

• Power-up Logic - Reset (relay on) or Normal (same as before power down)

• Lockout selection

Power Up Logic

Configurable power-up logic lets you select the latching output relay to require “RESET”or to provide normal operation at power-up. If power to the limit controller fails andpower is reapplied, the controller goes through power up tests then starts in one of thefollowing configurable conditions:

• If you configured RST at setup group “LIMIT”, the lower display will blink “LIMIT”at power up. This will require reset via the [MAN-AUTO RESET] key or external switchto obtain normal operation.

• If you configured NORM at setup group “LIMIT”, the display and limit controllerwill function normally at power up, (that is, no reset of the latching relay is requiredunless a limit has been exceeded). If the limit was latched when power went down,the unit will be in limit at power-up.

Refer to Section 4 - Configuration, subsection 4.5 Limit Parameters Set Up Group underSET UP prompt “LIMIT” and make your selection at FUNCTION prompt “POWRUP.”

Operation


How to Reset the Latching Relay

The latching relay cannot be reset until the PV input signal drops below the high setpoint (High Limit) or rises above the low set point (Low Limit) value.

Press the [MAN-AUTO RESET] key or make contact closure of an external switch if theExternal Reset option is present.

Using the Digital Input Option (External Reset)

The Contact Input option detects the state of external contacts. On contact closure, thecontroller will reset the latching relay if the controller has External Reset enabled. Toallow External Reset (contact input) use the procedure in Table 5-4.

5.7 Alarm Setpoints

Introduction

An alarm consists of a relay contact and an operator interface indication. The alarm relayis de-energized if setpoint 1 or setpoint 2 is exceeded.

The alarm relay is energized when the monitored value goes into the allowed region bymore than the hysteresis.

The relay contacts can be wired for normally open (NO) energized or normally closed(NC) de-energized using internal jumper placement. See Table 2-4 in the Section 2 –Installation for alarm relay contact information.

There are four alarm setpoints, two for each alarm. The type and state (High or Low) isselected during configuration. See Subsection 4– Configuration for details.

6 Input Calibration

6.1 Overview

Introduction

This section describes the field calibration procedures for Input 1.

• Every UDC2300 Limit controller contains all input actuation ranges, which are fullyfactory-calibrated and ready for configuration to range by the user.

• However, these procedures can be implemented if the factory calibration of thedesired range is not within specification.

FIELD CALIBRATION WILL BE LOSTThe field calibration will be lost if a change in input type configuration is implemented at a later time. Theoriginal factory calibration data remains available for later use after a field calibration is done. Seesubsection 6.6 if you want to restore factory calibration.

6.6 Restore Factory Calibration

Introduction

The factory calibration constants for all the input actuation types that can be used with thecontroller are stored in its nonvolatile memory. Thus, you can quickly restore the“Factory Calibration” for a given input actuation type by simply changing the actuationtype to another type and then changing it back to the original type.

Refer to Table 6-9 Restore Factory Calibration for procedure.

A restored factory calibration overwrites any previous field calibration done for the input and may changethe High and Low Range Limits. Be sure to protect any field calibration from accidental overwrites byconfiguring the appropriate LOCKOUT selection after calibration. See the Section 4 - Configuration forspecific instructions to set the lockout.
