JC-23D2 Flue Temp, Opacity, Draft Controller

NYC DEP Accepted

Installation & Operation Instructions

The JC-23D2 3-in-1 Flue Temp, Opacity and Draft controller maintains the

flue gas at a constant positive or negative Draft by modulating the outlet

damper on a boiler or furnace while also monitoring flue gas temperature

and stack opacity. A separate 4-20mA Draft transmitter is required to

modulate the damper.

The JC-23D2 interfaces to the burner flame safeguard to automatically

sequence the outlet damper Open for: Purge, Light-Off, and Post-Purge.

The sequence closes the damper after the burner shutdown to minimize

heat loss up the stack.

A separate time delayed Draft Cutout switch wired into the flame safeguard

Lockout Limits is required by Code for Safety.

The JC-22XMTR-xxCO includes a separate Draft xmtr and a separate time

delayed Draft Cutout switch in a single enclosure to reduce installation effort.

The JC-23D2 includes a burner shutdown relay that can be wired into the

FSG limits circuit for a high flue temp shutdown or a high opacity shutdown

or both.

Features

 Automatic Draft Control for increased boiler efficiency and reliability.

 Precision Outlet Draft Control for low NOx induced FGR burners.

 Firing Rate Feedforward option is included and assures stable draft during

load changes. Separate curves for up to two fuels.

 Automatic Damper Sequencing for purge, lightoff, post-purge burner

shutdown, and standby. Simple Flame Safeguard interface.

 Damper Adjustable Start Position option is included for installations with

excessively high draft during lightoff.

 High Flue Temp, Draft, and Opacity Alarms with time stamped alarm and

event history.

 Light Source and Sensor 190851S and 190851D interface directly with

the JC-23D2.

 Opacity Calibration is automated, there are no manual adjustments.

 Automatic Opacity Calibration can be configured to occur when the burner

fan shuts off.

 Flue Temperature Sensor accepts Type J or K thermocouple input.

 5” Color LED Touchscreen for easy viewing. All setup can be done from

the touchscreen.

 Modbus Communication with RS-485 and Ethernet capability.

High Flue Temp Alarm Sequence

The Bargraph and Numeric display continuously indicate the flue gas temperature (FGT). The “Warning” and “Shutdown” alarm

setpoints are indicated on the bargraph with tic marks. If the FGT exceeds the Warning Setpoint for more than 30 seconds

(adjustable), the bargraph blinks, the WARNING message appears, the Common Alarm Relay energizes, and the current

temperature is logged with a time/date stamp. Pressing the ALARM SILENCE button de-energizes the Common Alarm Relay.

If the FGT continues to increase and exceeds the Shutdown setpoint for more than 15 seconds (adjustable), the bargraph blinks,

the SHUTDOWN message appears, the Shutdown relay de-energizes and latches into “Manual Reset” mode, the Common

Alarm Relay re-energizes, and the current temperature is logged with a time/date stamp. Pressing the ALARM SILENCE button

de-energizes the Common Alarm Relay.

If the JC-23D2 Shutdown relay is wired into the burner Start Limits, the burner shuts down. The Shutdown Relay remains

de-energized and the SHUTDOWN message remains on the display. After the temperature has fallen below the “shutdown”

setpoint, the Operator can press the RESET pushbutton to energize the Shutdown relay.

The Common Alarm Relay can be used to activate an external bell or horn. If the JC-23D2 is not in SHUTDOWN, the Common

Alarm Relay de-energizes automatically when the temperature drops below the Warning Alarm setpoint. Alternately, pressing the

JC-23D2 Alarm Silence pushbutton, or energizing the 120 Vac Alarm Silence input, or the 24 Vdc Alarm Silence input, or

sending a Modbus command will de-energize the Common Alarm Relay in order to silence an audible alarm.

Opacity Alarm Sequences

STANDARD Sequence

The hash mark to the right of the bargraph indicates the Alarm Setpoint. The Alarm contacts will close and the bargraph will blink

if the Opacity has been above the Setpoint continuously for 20 seconds (adjustable from 0-120 sec.).

Press the Silence button to stop the blinking and to de-energize the Alarm Relay (typically wired to an external bell, horn, or

strobe).

When the opacity drops below the Setpoint, the bargraph will stop blinking and the Alarm relay will de-energize (if it hadn’t

already been Silenced).

If the Opacity is continuously above the Alarm Setpoint for more than 120 seconds

(adjustable from 0-180 sec.), the Shutdown relay will de-energize and display the message SHUTDOWN. Typically, the

Shutdown relay N.O. contacts are wired in series with the burner Operating Limits circuit and this will cause the burner to

shutdown.

After the opacity has dropped below the Alarm Setpoint, you must press the RESET button to re-energize the Shutdown before

the burner can re-start (assuming the shutdown contacts are wired to shutdown the burner). The Shutdown Relay remains

de-energized, the burner will not re-start, and SHUTDOWN is displayed until the JC-23D2 has been RESET.

If the AC power has cycled Off and then ON, the JC-23D2 cannot be RESET until after the Lamp has completed WARM UP.

NYC-BAR Sequence

The NYC-BAR Sequence is the same as the STANDARD Sequence described above with two differences:

The Alarm Time Delay is fixed at 0 seconds and cannot be adjusted. This means that the Alarm Relay will activate as

soon as the Opacity is greater than the Alarm Setpoint.

The Shutdown Time Delay is fixed at 120 seconds and cannot be adjusted.

A 30% Opacity Test Filter is attached to the Light Source. You can clean the windows/Lens and then hang the filter on the

screw to verify that the Alarm Setpoint is set correctly and that the calibration is reasonable. The 30% Opacity value of the filter is

approximate.

SDI-JC-23D2 rev 8-23-22 page 6 of 36

Operation (Continued)

Window-Lens Cleaning

 The Light Source window, Light Detector lens, and any Purge Cap windows should be

cleaned periodically. Use a soft, lint free cloth dampened with "Windex".

 Re-calibrate after every cleaning (from the CALIBRATE Menu) .

 If cleaning the windows/lens and re-calibrating doesn’t clear the “LENS IS DIRTY”

message, then the Source and Detector might need to be re-aligned.

The message “LENS IS DIRTY” is displayed after a calibration when:

0% Opacity mA is less than 15 and Detector Gain = High and Lamp Brightness =17.

Re-calibration fails when 0% Opacity (“0 mA”) is less than 8.

The Calibration History screen (Menu/Calibrate Opacity/Calibration History) shows the results of the last 60 calibrations.

The trend of increasing Lamp values, then decreasing 0 mA values, allows you to anticipate a nuisance Opacity shutdown.

“Before” is the Opacity (due to dirt/soot) just before a calibration.. If these values are consistently near the Alarm setpoint,

increase Purge air flow or service the burner or re-calibrate more frequently, to prevent nuisance shutdowns.

“Fan Starts” is the number of starts since the last calibration. If a small number of starts increases “Before” opacity, consider

cleaning the oil nozzles or changing the burner light-off settings to reduce the initial puff of soot.

If the AutoCal is enabled (see page 10), the time interval between Lens cleanings will be much longer because AutoCal

calibrates out the normal dust build-up on the optical surfaces. AutoCal can prevent nuisance Lockouts due to soot buildup.

Calibration

Calibration is required After Installing; After cleaning the windows & Lens; After Source or Detector re-alignment; or

After the LED Lamp has been replaced.

How to Start a Calibration:

 The burner fans must be OFF during the entire calibration.

 Once started by the User, Calibration is fully automated and takes

approximately 3 minutes.

 From the Home screen, touch Menu, then Calibrate Opacity,

then Calibrate Now

 Wait: For Stack to Clear displays and counts down to 0 after the

burner Fan stops to allow dust to settle.

 Wait: Lamp Warming Up displays and counts down to 0 when

initially powered up, or whenever the Lamp has been Off.

 When both Waits are done, the Start button appears.

Press Start to begin the Calibration.

Press Back, Home, Silence, Alarms, or History on any of the

Calibration screens to abort the Calibration process.

 During the first phase of calibration, the 190851x Light Source

“Auto Ranging” occurs, as follows:.

The Lamp brightness (2-17) and Detector Gain (Low/High) are

automatically varied to find the maximum Detector mA signal.

The Wait timer counts down from 180 seconds, but can complete

Auto Ranging in as short as 120 sec. (depending on distance,

alignment, etc…)

Calibration (continued)

 After a successful AutoRanging is completed, Opacity Calibration begins with the Lamp

ON to find the 0% Opacity mA signal.

 10 second Wait for the mA signal to start to settle down.

 After that, every 5 seconds the Detector mA signal is checked.

 When two successive mA vales are within 0.3% of each other, the 0%

Opacity value is saved.

 Then the Lamp is turned OFF to find the 100% Opacity mA signal.

 When two successive mA vales are within 0.3% of each other, the 100% Opacity

value is saved.

 After a successful Calibration is completed, the Auto Ranging and Calibration data is

displayed and is also stored in the Calibration History Log.

 The Lamp turns back ON and the Warm Up delay counts down.

 If an Error occurs during Auto Ranging or Opacity Calibration, this screen will display

with the Error Message (see Trouble Shooting section)

 This screen will continue to be displayed (forever) until the Back, Home, Silence,

Alarms, or History button is touched.

 If CLEAN LENSE is displayed on the Status line, the Detector mA signal is very weak.

Opacity has been successfully Calibrated.

However, if the Optics aren’t cleaned and/or re-aligned, the next Calibration might not be successful.

AutoCal After Burner Shutdown

The main reason for Opacity drift and/or nuisance burner trips is soot/dust build-up on the windows or the Detector lens.

A calibration cycle cancels out the normal dust/soot build-up on the optical surfaces.

The JC-23D2 can initiate an unattended fully Automated Calibration (AutoCal) cycle after the burner fan stops running.

The calibration screens above are not displayed during AutoCal. The normal bargraph screen is displayed with the status

message Auto Calibration in Progress. After a successful AutoCal has completed Calibration Successful is displayed and

the data is saved in the Calibration Log. If AutoCal is not successful, the last successful calibration data will continue to be used.

To enable this feature: In the Configure/Setup menu, enable the AutoCal Option, and

Wire terminal 8 to the 120 Vac fan starter coil as shown in the Wiring section.

See the Menu section (page 10) for additional AutoCal settings.

also starts the 15 sec. (adjustable.) When the timer expires, the

Fan Delay relay closes, which completes the Burner Limits input

which starts the Burner fan. By then the outlet damper should be

open enough to prevent pressurizing the furnace with the burner

fan running.

3. Purge When both burner and outlet damper

Draft Control Types, Control Options, and Actuators

The JC-23D2 allows field selection of: control types, output/actuator type etc…. The field wiring and the required auxiliary

equipment changes based on the selections made. Please read the following descriptions.

Control Types: Floating vs. PID

 Floating control has (2) tuning adjustments: Deadband (DB) and Proportional Band (PB). PB slows down the actuator/VSD

rate of change (speed) as the Draft approaches the Setpoint, which makes overshoot and oscillation less likely. This makes

it easier to tune and provides very good control.

 PID control has (3) tuning adjustments: Deadband (DB), Proportional Band (PB), and Integral (I) (also called “Reset”).

Instrument Technicians are typically more familiar with this type of controller tuning and can tune for tight Draft control.

However, burner technicians who are less familiar with PID tuning can improperly tune the controller and inadvertently

cause overshoot and Draft control oscillation.

Command Types: Triac vs. mA

 Triac output is used with a 3 wire AC reversible actuator with Open, Close, Neutral terminals. The JC-23D2 internal solid

state Triacs energize the Open or Close outputs. Some Triac actuators have a position feedback potentiometer, such as:

models R-AL-2A, SM-xx, UM-xxx, some do not: models: PL-2A-xxx. Triac actuators without a position feedback pot

can not be used with some features, see the compatibility chart below.

 4-20 mA or 0-20 mA output can be used with actuators that have with built-in “positioners” (electric or pneumatic) that move

the actuator to a position proportional to the mA command. mA outputs can also command an ID Fan VSD.

External resistors (available separately) can be used to convert the mA signal into a wide variety of DC voltage signals:

1-5V, 2-10V, 0-5V, 0-10V. The Adjustable Starting Position option cannot be used with a mA Command actuator or VSD.

Firing Rate Feedforward

 During a burner firing rate change, Feedforward control starts to move the damper (or VSD) before the change in burner air

flow causes the draft to deviate from the Setpoint. This is very beneficial for low NOx burners that require tight FGR and air

flow control in order to prevent combustion issues. The JC-23D2 has a Feedforward Proportional Band tuning adjustment

and has 2 “firing rates versus damper position” Feedforward curves for dual fuel burners. See the compatibility chart below.

 A burner Firing Rate signal is required: 4-20mA, 0-5V, 0-10V, or Potentiometer. The Model SPS (Shaft Position Sensor)

includes linkage for jackshaft style burners

Adjustable Start Position Option

 Installations with extremely tall stacks, or with an oversized ID fan, can create an excessively negative draft if the

Draft Damper wide open during light-off. This can cause nuisance pilot flame failures. The default JC-23D2 sequence

positions the damper wide open for Purge, Ignition, and Main Flame Trial.

 The Adj. Start Position option positions the damper wide open for Purge and then moves to a partially closed position after

Purge completes. When the damper reaches this position, if the measured draft not sufficiently negative, the damper will jog

open until the Draft is more negative that the User set Adj. Start Draft Setpoint. When the Draft is acceptable, the

JC-23D2 Adj Start Relay Output energizes.

 NOTE: This Option should NOT be used unless absolutely required by the site conditions. This Option requires a second

damper proving switch to be used as a Burner Flame Safeguard Ignition Interlock, see page 11 wiring diagram.

Installation

JC-23D2 Indicator Mounting:

The JC-23D2 Indicator is designed for flush mounting in an enclosure

located rated NEMA 12 or better.

The JC-23D2 should not be subjected to excessive vibration.

Continuous operation is guaranteed over the 32-131 F (0-55C) ambient

operating range.

Temperature Sensor Mounting:

The 20” 104087D and the 12” 104087E type J thermocouple temperature

sensors are designed for mounting in a NEMA 4 environment.

The thermocouple should not be subjected to excessive vibration.

Locate the temperature sensor where the tip of the probe will sense a

representative flue gas temperature.

Typically, the tip should be in the middle 1/3 of the flue gas duct. Shielded T/C

extension wire is recommended.

Light Source & Detector Mounting

The Light Source and Detector are designed for mounting in an indoor NEMA 1

environment, with 32-149F (0-65C) ambient, and without excessive vibration.

 See last page for Full Size Cutout Template.

 Locate such that the light beam passes through the complete smoke profile

at all flow rates. See the sketch at right for locations after an Elbow, T, Fan,

Damper, or other uneven flow profile.

 Do NOT locate the Light Source and Detector near any sources of bright

light (outside windows, light fixtures, …). If this is not possible, 190713

Light Shields may be required.

 Do NOT locate the Light Source and Detector upstream from an Oxygen

Analyzer. Air entering the duct would give a false stack Oxygen indication.

 Locate the Source and Detector where it is accessible for routine cleaning.

 The distance from the face of the Light Source to the face of the Light

Detector must be greater than 3 ft. and less than 10 ft.

 The ¾" mounting pipe should be horizontal.

 The ¾" mounting pipe maintains the optical alignment from the Source to the

Detector. The flue gas heat expands and contracts the pipe length.

One end of the mounting pipe should be welded, or clamped, to the duct.

The other end of the mounting pipe must be free to move.

Do NOT connect BOTH ends of the mounting pipe to the duct.

Do NOT use 2 stubs on opposite sides of the duct to mount the Source and

Detector because the alignment will shift as the duct heats and cools.

 For positive pressure ducts, install a pressure cap (ie, window) to prevent flue gas and dust from exiting the duct. The

107226P pressure caps can be used without purge air for low soot installations. For high soot applications, clean dry

compressed air should be connected to 107226P pressure caps.

See SDI-107226P instructions for further details.

 If Clean, dry compressed air is not available, the 190275A Blower Caps

are suitable for duct pressures less than +1.0" wc.

See the 190275A instructions for further details.
