INTRODUCTION AND DIMENSIONS

Selectra SERIES 14 electronic gas flame modulation systems are designed primarily for make-up air heating, as components of direct fired equipment. They may be field installed on existing equipment or specified for new equipment installation. Natural, manufactured, mixed, LP and LP gas air mixture are compatible gases.

The systems utilize Modulator or Modulator-Regulator valves. Am-plifiers are available with low-fire start, and with integral or remote temperature selection. A discharge air temperature sensor is mounted within a mixing tube housing.

SyStem optIonS

Option 1 - a room override thermostat provides space temperature control by raising the discharge air temperature to a pre-selected point - when used in conjunction with the remote temperature selector.

Option 2 - an inlet air sensor (and mixing tube) provides inverse change in discharge air for each degree change in inlet air - when installed in a convenient duct location upstream of the burner. Option 3- a dual temperature selector replaces TD114 to provide dual control for door heaters, or other applications such as paint spray booths (TD214_ or _X, or AD1214_).

SPECIFICATIONS

Power Requirements: 24 VAC, 50/60 Hz Class II transformer

NOTE: Transformer secondary must not be grounded in any portion of the circuit external to a Maxitrol amplifier. If exist-ing transformer is grounded, a separate isolated transformer must be used. Electrical interference may effect performance and/or damage equipment.

Ambient Limits: Operating..... -40o to 125o F / -40o to 52o C Non-operating..... -50o to 185o F / -46o to 85o C

Gases: Suitable for application in natural, manufactured, mixed gases, liquefied petroleum gases and LP Gas Air Mixture piping systems.

Remote (or Dual) Selector: Install in control cabinet or other chosen location. NOTE: Suffix letters must match, e.g. TS114A must be used with TD114A. For wiring runs longer than 200 ft. substitute ES261-1/ES261-2 for TD114. The ES261s are a 2-piece version of the TD114. ES261-1 is a temperature setting dial only, ES261-2 must be mounted at furnace location.

Discharge Temperature Sensor / Mixing Tube Assembly: sensor housed in mixing tube, install in discharge air stream.

Optional:

Dual Temperature Selector: see preceding Remote/Dual selector.

Room Override Stat: mount in heated area not in direct path of discharge air stream.

Inlet Air Sensor: install in convenient location upstream of burner, in intake air duct.

INSTALLATION OF COMPONENTS Control wires connected to the Override Stat, Discharge Air Sensor, or Remote Temperature Selector must not be run close to or inside conduit with power or ignition wires. Doing so may cause the unit to function erratically or may destroy the amplifier. If shielded wires are used, shield must be insulated and grounded at the amplifier location only.

Wiring Run: If control wiring is inside conduit with line voltage wiring, use shielded cable up to 100 ft. For best results up to 200 ft., run control wiring in separate conduit. For longer runs see Remote Selector below.

Amplifier / Amplifier-Selector: contains the wiring terminals and sensitivity adjustment - install in any convenient location that is protected from the weather and contaminated atmosphere.

typICAl GAS tRAInS Modulator (M) or Modulator-Regulator (MR) Valve: Mount in upright position in horizontal run of pipe, downstream of other controls - a separate gas pressure regulator must be used with any modulator (M) valve.

MR Valve: Modulator-regulator valve

M Valve: Regulator upstream of modulator valve

Vent: M411, 511, 611.....vertical vent outlet 1/8” NPT - 12A06 installed. MR212.....two vents located in upper housing, both equipped with vent limiting means

Pressure Limits: Maximum Discharge Pressure: (M411, 511, 611)................ 7” w.c. / 17 mbarStatic Pressure Rating: (M411, 511, 611).................5.0 psi / 345 mbarMaximum Operating Inlet Pressure: M411, 511, 611................. 1 psi / 70 mbar MR212.............................. 5.0 psi / 345 mbarMaximum Emergency Exposure*: M411, 511, 611.................. 3.0 psi / 210 mbar MR212............................... 12.5 psi / 862 mbar * May not function properly at this pressure, but will suffer no internal damage

PRELIMINARY CIRCUIT ANALYSIS

For ease in troubleshooting, it is advisable to wire the system as follows (this differs from the normal connection). The Discharge Air Sensor is disconnected and replaced with a 10,000 ohm, 1/2 watt test resistor (terminals 3 and 4). If inlet air sensor is being used, disconnect and replace with a jumper. On units where the Remote Temperature Selector is located a considerable distance from the heater, it may be advantageous to connect the selector at the heater location.

Connect a DC volt meter (capable of reading 0-24 V DC) on the Modulator or Modulator-Regulator Valve terminals. Set the temperature to the minimum dial setting. The DC voltage should read 0 volts. The DC voltage should gradually increase to at least 20 volts as you slowly rotate the dial to the maximum dial setting. If these voltages are obtained, the valve function can now be checked out.

The operation of the valve with regard to voltage is as follows: from 0 volts to approximately 5 volts, the modulating valve should be on bypass flow with the heater operating on low or minimum fire. From approximately 5 volts to 15 volts DC, the valve should be performing its modulating function, and the heater should be firing at a modulated flow rate between low and high fire, depending upon the voltage. Above approximately 15 volts DC, the valve should be delivering full flow to the heater and the unit should be on full fire. If the DC voltage is obtained on the valve terminals, but the heater does not respond as described, the problem can be isolated to the valve itself or to the gas control manifold of the heater (see check list, pages 4 and 5).

In the event proper voltages are obtained, and the valve responds correctly to these DC voltages, the problem could well be in the wiring leading to the Discharge Air Sensor or the Discharge Air Sensor itself. This should be also reviewed in the check list.

If the proper voltages are not obtained when wired as instructed, the problem can be isolated to the electronics and this may once again be reviewed in the check list.

After the troubleshooting test, remove the test resistor and recon-nect the Discharge Air Sensor to terminals 3 and 4. If Remote Tem-perature Selector has been moved return it to its original position.

SENSITIVITY ADjUSTMENT

The sensitivity control will allow the user to control the response of the system. Caution should be exercised in the use of this adjustment. Under normal usage the pointer should be located on the mark on the label (A1014).

If hunting is encountered (rapid oscillation), rotating the sensitivity adjustment (R23 on A1014U, AD1014U) counter-clockwise will dampen the oscillation - stabilizing the flame.

DO NOT adjust unless necessary, because decreasing the sensitivity will increase the temperature “DROOP” of the system.

A1014U & AD1014U LOW FIRE START TIME ADjUSTMENT

The low fire start duration can be set to approximately 0, 10 or 20 seconds, and begins timing after the amplifier has been energized.

The time is set by placing the jumper over the appropriate jumper block pins.NOTE: When low fire start is desired the jumper must be removed from the J6 jumper block and placed on the J5 jumper block.

The M/MR valve remains in the low fire setting position during the low fire start time period.

M411, 511, 611 VALVE

high Fire Manifold Adjustments: 1. Disconnect wires from amplifier terminal #4 (see page 7),

this causes the valve to call for continuous high fire.2. Adjust the pressure regulator to obtain the desired manifold

pressure (7” w.c. maximum).3. Reconnect the wires to amplifier terminal #4.

Low Fire or Bypass Adjustments:1. Disconnect wire from amplifier terminal #8, this causes the

valve to call for continuous low fire.2. Remove cap (A), and turn adjusting screw (B) to desired

low fire adjustment. (Clockwise rotation reduces minimum flow rate.)

3. Replace cap (A), and reconnect wire to amplifier terminal #8.

TEMPERATURE CALIBRATION

NOTE: The components of this system are individually calibrated and are not part of a matched set. It is necessary to place an accurate temperature measuring device as near the Discharge Air Sensor as possible.

Set the Remote Temperature Selector at least 10 degrees above outside air temperatures.

VALVE ADjUSTMENTS

(See bulletin MT2035 for additional M/MR valve information)NOTE: Low fire adjustment should be checked whenever the high fire adjustment is changed.
