GENERAL DESCRIPTION

The CN63500 is a Factory Mutual approved temperature limit alarm, intended to provide an independent shutdown for thermal processes. The CN63500 accepts signals from a variety of temperature sensors (thermocouple or RTD elements), and its comprehensive programming allows it to meet a wide variety of application requirements.

Dual 4-digit displays allow viewing of the process temperature and limit setpoint simultaneously. Front panel indicators inform the operator of the process and output status. The main limit output and alarm outputs are field replaceable.

Relay alarm(s) can be configured to activate according to a variety of actions (Absolute HI or LO, Deviation HI or LO, and Band IN or OUT) with adjustable hysteresis. A standby feature suppresses the alarm during power-up until the process stabilizes outside the alarm region.

The unit is constructed of a lightweight, high impact plastic case with a tinted front panel. The front panel meets NEMA 4X/IP65 specifications when properly

EMC INSTALLATION GUIDELINES

Although this unit is designed with a high degree of immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield connection should be made as short as possible. The connection point for the shield depends somewhat upon the application. Listed below are the recommended methods of connecting the shield, in order of their effectiveness. a. Connect the shield to earth ground (protective earth) at one end where the

unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.

3. Never run Signal or Control cables in the same conduit or raceway with AC power lines, conductors, feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run through metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is effective.6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load. a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation.

varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life.

switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. External diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used.

1.0 INSTALLING THE CN63500

The CN63500 meets NEMA 4X/IP65 requirements for indoor use to provide a watertight seal in steel panels with a minimum thickness of 0.09 inch, or aluminum panels with a minimum thickness of 0.12 inch. The units are intended to be mounted into an enclosed panel. It is designed so that the units can be stacked horizontally or vertically. The bezel assembly MUST be in place during installation of the unit.

Instructions:

1. Prepare the panel cutout to the dimensions.

2. Remove the panel latch from the unit. Discard the cardboard sleeve.

3. Carefully remove the center section of the panel gasket and discard. Slide the panel gasket over the unit from the rear, seating it against the lip at the front of the case.

4. Insert the unit into the panel cutout. While holding the unit in place, push the panel latch over the rear of the unit, engaging the tabs of the panel latch in the farthest forward slot possible.

5. To achieve a proper seal, tighten the panel latch screws evenly until the unit is snug in the panel, torquing the screws to approximately 7 in-lbs (79 N-cm). Over tightening can result in distortion of the panel, and reduce the effectiveness of the seal.

Note: The installation location of the

CN63500 is important. Be sure to keep it away from heat sources (ovens, furnaces, etc.), and away from direct contact with caustic vapors, oils, steam, or any other process byproducts in which exposure may affect proper operation.

Multiple Unit Stacking

The CN63500 is designed for close spacing of multiple units. Units can be stacked either horizontally or vertically. For vertical stacking, install the panel latch with the screws to the sides of the unit. For horizontal stacking, the panel latch screws should be at the top and bottom of the unit. The minimum spacing from center line to center line of units is 1.96" (49.8 mm). This spacing is the same for vertical or horizontal stacking.

Caution: Disconnect power to the unit and to the output control circuits

to eliminate the potential shock hazard when removing the bezel assembly.

Unit Removal Procedure

To remove a unit from the panel, first loosen the panel latch screws. Insert flat blade screwdrivers between the latch and the case on either side of the unit, so that the latches disengage from the grooves in the case. Push the unit through the panel from the rear.

Removing Bezel Assembly

The bezel assembly must be removed from the case to replace the output board. To remove the bezel assembly, insert a flat blade screwdriver into the pry slot on either side of the unit. Twist the screwdriver handle until the unit is ejected enough to allow removal.

Caution: The bezel assembly contains electronic circuits that can be damaged

by static electricity. Before removing the assembly, discharge static charge on your body by touching an earth ground point. It is also important that the bezel assembly be handled only by the bezel itself. Additionally, if it is necessary to handle a circuit board, be certain that hands are free from dirt, oil, etc., to avoid circuit contamination that may lead to malfunction. If it becomes necessary to ship the unit for repairs, place the unit in its case before shipping.

Installing Bezel Assembly

To install the bezel assembly, insert the assembly into the case until the bezel is fully seated against the lip of the case. Properly installing the bezel assembly is necessary for watertight sealing.

2.0 WIRING THE CN63500

After the unit has been mechanically mounted, it is ready to be wired. All wiring connections are made to the rear screw terminals. When wiring the unit, use the numbers on the label and those embossed on the back of the case, to identify the position number with the proper function.

All conductors should meet voltage and current ratings for each terminal. Also cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the unit (AC or DC) be protected by a fuse or circuit breaker. Strip the wire, leaving approximately 1/4" (6 mm) bare wire exposed (stranded wires should be tinned with solder). Insert the wire under the clamping washer and tighten the screw until the wire is clamped tightly.

Caution: Unused terminals are NOT to be used as tie points. Damage to the

CN63500 may result if these terminals are used.

POWER WIRING

AC Power

Primary AC power is connected to terminals #11 and #12, labeled AC. To reduce the chance of noise spikes entering the AC line and affecting the CN63500, an AC feed separate from that of the load should be used to power the CN63500. Be certain that the AC power to the CN63500 is relatively “clean” and within the variation limit. Connecting power from heavily loaded circuits or circuits that also power loads that cycle on and off (contacts, relays, motors, etc.), should be avoided.

DC Power

DC Power (18 to 36 VDC) is connected to terminals #11 and #12 labeled DC+ and DC- respectively.

CAUTION: Observe proper polarity when connecting DC voltages. Damage to the unit may occur if polarity is reversed.

RTD

When connecting the RTD, be certain that the connections are clean and tight. RTD sensors have a higher degree of accuracy and stability than thermocouple sensors. Most RTD sensors available are the three wire type. The third wire is a sense lead for canceling the effects of lead resistance of the probe. Four wire RTD elements may be used by leaving one of the sense leads disconnected. Two wire RTD sensors may be used in either of two ways: A) Attach the RTD to terminals #8 and #10. Install a copper sense wire of the

same wire gauge as the RTD leads. Attach one end of the wire at the probe

and the other end to terminal #9. Complete lead wire compensation is

obtained. This is the preferred method. B) Attach the RTD to terminals #8 and #10. Install a shorting wire between

terminals #9 and #10. A temperature offset error of 2.5°C/ohm of lead

resistance exists. The error may be compensated by programming a

temperature offset.

Note: With extended cable runs, be sure the lead resistance is less than 15 ohms/

lead.

Thermocouple

When connecting the thermocouple, be certain that the connections are clean and tight. If the thermocouple probe cannot be connected directly to the CN63500, thermocouple wire or thermocouple extension-grade wire must be used to extend the connection points (copper wire does not work). Always refer to the thermocouple manufacturer’s recommendations for mounting, temperature range, shielding, etc. For multi-probe temperature averaging applications, two or more thermocouple probes may be connected to the CN63500 (always use the same type). Paralleling a single thermocouple to more than one CN63500 is not recommended. Generally, the red wire from the thermocouple is negative and connected to the CN63500’s common.

The front panel bezel material is flame and scratch resistant, tinted plastic that meets NEMA 4X/IP65 requirements, when properly installed. Continuous exposure to direct sunlight may accelerate the aging process of the bezel. The bezel should be cleaned only with a soft cloth and neutral soap product. Do NOT use solvents. There are two 4-digit LED displays, a red upper Main Display and a lower green Secondary Display.

There are up to four panel annunciators, with red backlighting, that illuminate to inform the operator of the CN63500 and output status. See the front panel diagram for a description of the annunciators. Four front panel buttons are used to access different modes and parameters. The following is a description of each button.

Do NOT use tools of any kind (screwdrivers, pens, pencils, etc) to operate the keypad of this unit.

Button Functions

R - The Reset (R) button is used to reset the limit and alarm relays. The limit output

cannot be reset until the process temperature returns to the proper operating

range. Latched alarms can be reset regardless of limit exceed condition. P - The Parameter (P) button is used to access programming, enter the change,

and scroll through the available parameters in any mode. UP, DN - The Up/Down buttons are used to modify parameters.

CN63500 POWER-UP

Upon applying power, the CN63500 delays input indication and control action for five seconds to perform several self-diagnostic tests and to display basic CN63500 information. Initially, the CN63500 illuminates both displays and all annunciators to verify that all display elements are functioning. The CN63500 then displays the programmed input sensor type in the main (top)

display and the revision number of the CN63500’s operating system in the secondary (bottom) display. The CN63500 checks for correct internal operation and displays an error message (E-xx) if an internal fault is detected. (See the Troubleshooting section for further information.)

Upon completion of this sequence, the CN63500 begins displaying the input

value and setpoint, and updates the outputs based upon this condition.

CN63500 CONFIGURATION OVERVIEW

The CN63500 is programmed with certain parameter settings from the factory. Factory settings are listed in parentheses in the various Configuration of Parameters tables. In many cases, these settings must be changed to the particulars of the application before proper operation can be started.

The CN63500 is typically in the Normal Display Mode. In this mode, the process temperature is displayed in the main (top) display, and the limit setpoint is displayed in the secondary (bottom) display. When changes to the parameter configurations are needed, the P button is pressed, and the CN63500 will enter into the Parameter Mode.

PARAMETER CONFIGURATION BASIC STARTUP

For basic start-up, it is important to verify or change Input Parameter Module (1-IN) parameters tYPE and SCAL, and Output Parameter Module (2-OP) parameter LiAC (Limit Trip Action). For alarm set-up, it is important to verify or change Alarms Parameter Module (4-AL) parameters ACt1, AL-1, ACt2, and AL-2.

If the above Input parameters or the input wiring connections are not correct, then the main (top) display may display an error message or incorrect value. Verify the input programming and wiring. (If incorrect display continues, refer to the Troubleshooting section.) All other parameter configurations are important but will not prevent the CN63500 from showing a correct display.

4.0 PARAMETER MODE

The Parameter Mode is accessed by pressing the P Button from the Normal Display Mode. While in the Parameter Mode, the temperature is displayed in the main (top) display, and the parameter is displayed in the secondary (bottom) display. The correct password must be entered before any parameters can be accessed. To modify values, use the UP or DOWN button while the parameter is displayed. Use the P button to accept the new value, and to scroll through the parameters. The CN63500 will automatically return to the normal display mode if no action is taken. The CN63500 responds to the new

The Alarm parameters can be independently locked out from appearing. See Configuration Module 3, Parameter Lock-outs.

These modules allow access to the fundamental set-up parameters of the CN63500. The modules are grouped into related programming steps, such as inputs, outputs, alarms, etc. Upon completion of each module, the program returns to “CNFP”.

When the parameter list has been scrolled through, the CN63500 will display “End” momentarily, and then return to the normal display mode.

CONFIGURATION PARAMETER MODULES

The Configuration Parameter modules are accessed by pressing the UP button from CNFP in the Parameter Mode. The UP or DOWN buttons can be pressed to move to the desired Parameter Module. The P button is then pressed to enter into that module. The main (top) display will be the parameter, and the secondary (bottom) display will be the parameter value. The UP or DOWN buttons are used to modify the desired parameter value, and the P button enters the new value, and moves to the next parameter. The CN63500 responds to the new values after the

P button is pressed, however, the change is not committed to permanent memory until the CN63500 is returned to the Normal Display Mode. If power loss occurs before returning to the Normal Display Mode, the new values must be entered again. At the end of each module, the CN63500 will go back to CNFP. Other Parameter Modules can be accessed by pressing the UP or DOWN buttons, or pressing P will return to the Normal Display Mode.

Parameters that are model number, or program dependent will only be

displayed when the appropriate options are installed or programmed.

DESCRIPTION/ COMMENTS

Select from the list of various thermocouple and RTD sensors.

Select either degrees Fahrenheit (F) or degrees Celsius (C). If

changed, be sure to check all parameters.

Select either 1 or 0.1 degree resolution. If changed, be sure to check all parameters.

Select the relative degree of input signal filtering and display update rate. The filter is an adaptive digital filter that discriminates between measurement noise and actual process changes. Therefore, the influence on step response time is minimal. If the signal is varying too greatly due to measurement noise, increase the filter value. Conversely, if the fastest CN63500 response is desired, decrease the filter value.

If the CN63500 temperature disagrees with a reference temperature instrument or if the temperature sensor has a known calibration, the CN63500 temperature can be compensated by a correction offset. The following equation expresses the relationship: Desired Display Temp = (CN63500 Temp) + SHFt. Normally set to 0.

The CN63500 has programmable high and low setpoint limit values to restrict the setting range of the limit setpoint. Set the limit values so that the temperature setpoint value cannot be set outside the safe operating area of the process. SPHI must be above SPLO.

DESCRIPTION/ COMMENTS

When deviation low-acting with positive alarm value (d-LO), deviation highacting with negative value (d-HI), or band inside-acting (b-IN) is selected for the alarm action, the indicator is OFF when the alarm output is ON. See the Alarms section for complete details of each action. If changed, check alarm values.

Automatic reset alarms are reset by the CN63500 when the alarm condition clears. Latched alarms require operator action to reset the alarm condition. The front panel R button, if enabled, can be used to reset a latched alarm (see FPrS in Configure Module 3). A latched alarm condition may also be reset via the Remote Reset input. See the Reset Action diagram in the Alarms section.

The alarm(s) may be independently configured to exhibit a power-on, standby delay which suppresses the alarm output from turning ON until the temperature first stabilizes outside the alarm region. After this condition is satisfied, the alarm standby delay is canceled and the alarm triggers normally, until the next CN63500 power-on. This feature also works for deviation and band alarms when the setpoint is changed via keypad. This action suppresses “nuisance” alarms. See the Alarm Standby diagram in the Alarms section.

The alarm values are either absolute values, or relative to the limit setpoint value (deviation and band alarms). An absolute alarm value is the value that is entered for the alarm. A relative alarm value is the mathematical sum of the temperature limit setpoint value and the alarm value (positive or negative), thus a relative alarm tracks the limit setpoint value as it is changed. If the alarm action is set as a Band Alarm, then only a positive alarm value can be entered.

corresponding Alarm 1 parameter for description.

The alarm value(s) have a programmable hysteresis band to prevent alarm output chatter near the alarm trigger point. The hysteresis value should be set to eliminate this effect. A value of 2 to 5 is usually sufficient for most applications. A single alarm hysteresis value applies to both alarms. See the Alarm Action Figures, in the Alarms section, for the effect of hysteresis on the various alarm types.

* Model Number Dependent.

Entering code 66 restores all parameters to factory settings. The unit indicates the operation after the P button is pressed, by displaying “rSEt” in the lower display momentarily.

Caution: this operation erases the CN63500 calibration values and defaults the values to nominal settings. Reading errors of ±10% may result. Do not perform this operation unless the CN63500 has lost calibration. Loss of calibration is signaled by an “E-CL” error flag at power-up. To clear this flag, perform calibration procedure as noted in the Calibration section. Alternatively, “stepping” through one of the calibration procedures clears the error flag, but does NOT validate the calibration accuracy in any manner.

LIMIT OUTPUT ACTION

The limit output is selectable for high or low trip activation. If the process temperature goes above the limit setpoint for a high trip, or below the limit setpoint for a low trip, the limit relay will de-energize to initiate a process shutdown. The limit output cannot be reset until the process temperature returns to the proper operating range; manual reset is required. The following action figures describe the status of the limit output and the front panel indicators for various over/under setpoint, and reset conditions. Reset is either by the front panel R button, if enabled, or by the Remote Reset input, terminal #6. Refer to Configure Module 2 - Output Parameters for details of configuring the limit output.

CALIBRATION CHECKS

The instrument has been fully calibrated at the factory for all input types. If the unit appears to be indicating or controlling incorrectly, see the Troubleshooting section before attempting this procedure.

If the CN63500 is suspected of reading incorrectly, the instrument may be checked for indication accuracy without disturbing the factory calibration. The following procedures may be used for this purpose.

Note: Allow ½ hour warm-up before checking these parameters.

mV Reading Check

1. Connect a DC mV source with an accuracy of 0.03% or better to terminal #8

(-) & #9 (+).

2. Configure Input Parameters Module 1 for linear mV (Lin) input, under tYPE.

3. Compare the CN63500 read-out to the standard at various points over the range

(-5.00 mV to 56.00 mV). The tolerance is ±(0.15% of reading + 1 LSD).

4. Calibrate the CN63500 if the readings are out of tolerance.

Thermocouple Cold Junction Temperature Check

1. Connect a thermocouple probe of known accuracy (Types T, E, J, K, N only)

to CN63500. Select the probe used in Configure Module 1.

2. Connect a reference temperature probe to measuring end of thermocouple to

monitor temperature. Allow sufficient time for temperatures to equalize.

3. Compare CN63500 display with reference temperature probe. The CN63500

display should equal the calibrated probe temperature. (Tolerance is ±1ºC.)

4. Calibrate the cold junction temperature if out of tolerance.

RTD Ohms Reading Check

1. Connect RTD simulator (with an accuracy of 0.1 ohm or better) capable of operating with less than 150 µA to terminals #8, #9, & #10.

2. Configure Input Parameters Module 1 for linear ohms (rLin) input, under tYPE.

3. Compare the CN63500 read-out with the RTD simulator at various points over the range 2.0 to 300.0 ohms. The tolerance is ±(0.3% of span + 1 LSD).

4. Calibrate the CN63500 RTD ohms if out of tolerance.

Error Flag E-CL

If error flag “E-CL” appears at power-up, a loss of calibration parameters due

to noise spikes has occurred. Entering code 77 twice in Factory Service Operations Module (9-FS) erases the CN63500 calibration values and defaults the values to nominal settings. Reading errors of ±10% may result. It is recommended that the CN63500 be fully recalibrated. If using thermocouple only, the RTD calibration need not be performed.

Note: the “E-CL” flag may be cleared by “stepping” through cold junction

calibration procedure without the need to change any calibration values. A ±10% reading error will still exist.

Page 12

6.0 CALIbRATION

When re-calibration is required (generally every two years), this procedure should be performed by qualified technicians using appropriate equipment. Equipment source accuracy of 0.03% or better is required.

The procedure consists of: applying accurate mV signals, setting the thermocouple cold junction temperature, and applying precision resistance, among others. Allow a 30 minute warm-up period before starting this procedure. Do not use thermocouple wire for the millivolt or RTD ohms calibration.

Thermocouple Cold Junction Calibration (CJC)

This procedure must be performed AFTER an accurate mV calibration.

1. Exit Factory Service Operations (continually press P until “End”), and return to Normal Display Mode.

2. Connect a thermocouple probe of known accuracy to the CN63500 (Types T, E, J, K, and N only). Select the probe type used in Configure Module 1.

3. Connect a reference temperature probe to the measuring end of the CN63500 thermocouple probe. The two probes should be shielded from air movement and allowed sufficient time to equalize in temperature. (As an alternative, the CN63500 thermocouple probe may be placed in a calibration bath of known temperature.)

4. Compare CN63500 display with reference temperature probe (or calibration bath). If the displayed CN63500 temperature does not equal the reference probe temperature, calculate the CJ error as follows:

CJ Error = reference probe temperature - displayed CN63500 temperature

5. Enter Factory Service Operations Module (9-FS).
