Depressing the "Enter/Start" button as a final entry of the prestart condition, forwards a command signal from the computer chip energizing the motor control relay(s), and starts the motors. At the same time, a signal is also sent ener gizing the coil on the heat circuit relay. The valve is then energized after

the air-switch has been closed.

On the operating panel, the LED display shows that the dryer is operating in the drying mode, and also the drying time entered. The air switch closes soon after the motor is started. The glo-bar is ignited, and the primary valve is opened. Gas does not flow because of the normally closed flame switch (I.R. sensor switch) prevents the secondary valve from opening. In about 10-15 seconds the glo-bar is fully heated (from a "cold" 70°F. start). Its radiation

heats up the Bi-metallic flame switch, and the switch opens (25 - 40 seconds

later depending on its sensitivity and room temperature) permitting the gas to flow through the secondary valve. The glo-bar is essentially extinguished, but in this short period remains hot enough to ignite the gas. The gas flame radi ates enough heat to keep the I.R. flame switch open until the micro processor

heat circuit relay opens to shut off the gas.

When both the flame switch and heat circuit relay reclose, the secondary

valve closes and the ignition cycle is restarted. The temperature of the hot

air will continue to drop while either the heat circuit relay or the flame switch remains open. After both are closed, the air temperature continues to fall until the glo-bar is sufficiently reheated and radiates enough heat to reopen the flame switch since the glo-bar and flame switch are much warmer than they were at the start of the first ignition cycle, the time to recycle is re duced to 25-30 seconds total.

When the temperature at the temperature transducer has risen to the cut off

temperature corresponding to the heat value entered during prestart, the gas valve solenoid is de-energized, the valve closes, and the flame is extinguished. After 15 seconds, the gas valve solenoid is re-energized and ignition is reestab

lished by the glo-bar system. This cycle continues until the programmed drying

time has expired. This will then de-energize the P.C. mounted gas valve solenoid

and shuts off gas flow to the burner. The motor relay(s) remain energized allow

ing the blower and tumbler to rotate without heat.

On the operating panel, the LED display shows the dryer has entered the

cooling cycle, and will continue to run for the duration of cooling time entered

in the prestart condition, or approximately 5 minutes in the automatic mode.

When the cooling time has expired, the motor relay(s) are de-energized. The display on the operators panel shows "CCOO" (Cycle Complete - Zero Time Remaining).

Opening the door at the end of the cycle will remove "CCOO" from display and

"FILL" or F_D_ will return. If the door is opened during the cycle, the machine will turn off completely. The cycle may be continued by closing the door and pressing the "ENTER/START" button.

The motors are protected by an internal overload thermostat. If the blower

motor overheats, it will stop. The gas flame will be extinguished within a few

seconds when the air switch opens. If the air flow switch fails to open, the high limit thermostat will be heated by the standing burner flame and open to

de-energize the gas valve solenoid, and shut off the gas flow to the burner.

The temperature transducer is protected against failure by the micro

computer system. Should the transducer fail, be removed from its holder, or be subject to short or broken wire, the P. C. mounted relay will become de

energized and shut power to the gas valve and motor relays. Should this system

fail, the manual reset thermostat will open when its higher temperature (approx.

225°) is reached. It will remain open until manually reset.

Depressing the "Enter/Start" button as a final entry of the prestart condition,

forwards a command signal on the P.C. board. This permits the motor relay con tactors to be energized and starts the motors. At the same time, a signal is also sent energizing the coil on the heat circuit relay. The air flow switch closes soon after the blower motor is started and the coil of the oven contactors are energized to supply power to the oven elements.

When the temperature at the temperature transducer has risen to the cutoff temperature corresponding to the heat valve entered during the prestart, the heat circuit relay on the control panel opens, the oven contactor coils are de energized and the oven contactors open to shut off power to the oven elements.

After 15 seconds, or approximately lOop, the oven contactor coils are re-energized

and power is returned to the oven elements. This cycle continues until the drying time selected or the level of dryness selected has expired.

On the operating panel, the LED display shows the dryer has entered the

cooling cycle, and will continue to run for the duration of cooling time entered

in the prestart condition, or approximately 5 minutes in the automatic mode.

When the cooling time has expired, the P.C. mounted motor relay is de-energized

thus de-energizing the motor contactor relay. The display on the operators panel

shows "CCOO” (Cycle Complete - Zero Time Remaining).

Opening the door at the end of the cycle will remove "CCOO" from the display

and return "FILL” or F_D_. If the door is opened during the cycle, the machine

will turn off completely. The cycle may be continued by closing the door and

re-pushing the "Enter/Start" button.

The motor is protected by an internal overload thermostat. If the motor overheats, it will stop. The power to the oven will be shut off within a few seconds when the air switch opens. The dryer can be restarted after the over

load motor has sufficiently cooled. If the air switch fails to open, the high limit thermostat will be heated by the elements and open to de-energize the

oven contactor coils and shut off power to the elements.

The temperature transducer is protected against failure by the micro

computer system. Should the transducer fail, be removed from its holder, or be

subject to short or broken wire, the P.C. mounted relays will become de energized and shut power to the gas valve and motor relay. Should this system fail, the manual reset thermostat will open when its higher temperature is reached. It will remain open until manually reset.

R6URE I

To calculate area (in square inches) of round ducting: Area = diameter (in inches)

X Diameter (in inches) x .785. (Example: area of 12" diameter duct = 12 x 12 x

.785 = 113 square inches.)

EXHAUST DUCT AND AIR INTAKE,

a separate exhaust air duct for each dryer. The duct should be 12" or 16"

diameter, depending upon the air outlet diameter of the dryer. The duct

should go as directly as possible to the outside air. Avoid right angle turns

in the ducting; use 30 degree or 45 degree angles Instead. The radius of the

elbows should preferably be 1 1/2 times the diameter of the duct. To protect

the outside end of the duct from the weather, it may be bent downward as indicated

in Figure 1. Leave at least twice the diameter of the duct clear between the duct

opening and the nearest obstruction. If the exhaust duct goes through the roof,

Where possible, it is desirable to provide

FIGURE 2

10-2

it may be protected from the weather by a hood, or by using a 180 degree turn to

point the opening down as indicated in Figure 2. In either case, allow at least

twice the diameter of the duct as clearance from the nearest obstruction as in

dicated above.

Do not use screens or caps on the outside opening of the exhaust duct. The

ducting should be smooth inside, with no projections from sheet metal screws or

other obstructions which will collect lint. When adding ducts, the duct to be

added should overlap the duct that it is to be connected to. Provide inspection

Page 51

doors for periodic clean-out of lint from the main duct.

If it is not feasible to provide separate exhaust ducts for each dryer, ducts

from the individual dryers may be channeled into a common main duct. The

individual ducts should enter the bottom or side of the main duct at an angle

not more than 45 degrees and should be spaced at least 46" apart. The main

duct should be tapered, with the diameter increasing before each individual

duct is added. The minimum increase in cross-section area sliould be 115 square

inches for each 12" duct added and 205 square inches for each 16" duct added.

I'Jhere rectangular main ducting is used the areas shown should be increased 10

square inches, and the ratio of duct width to depth should not be greater than

3 1/2 to 1. Figure 1 shows the minimum cross-section areas of the main duct for

either 12" or 16" dryer ducts. These figures should be increased if the main duct

is unusually long (20' or over) or has numerous elbows in it.

Openings from the outside air to the room in which the dryers are operating should

be provided for make-up air and located as near to each dryer as possible. These

openings should be 3 to 4 times the cross-section area of the exhaust ducts.

Inadequate exhaust facilities may cause high temperature limit switches or air flow

switches to shut off the dryers. Do not disable the switches, which are provided

for your safety. Instead, investigate the exhaust ducting. Any obstruction or

air friction due to numerous elbows/fittings in the ducting will slo\v7 the passage

of air through the system with resulting inefficiency and potential fire hazard.

SUGGESTED STEAM COIL PIPING ARRANGMENT

FIG . 1

Care must be exercised when leveling steam dryers in final position. After level

ing the dryer, check the downward pitch of the heat exchanger from front to rear

with a level. Likewise, check the downward pitch of the return condensate manifold

toward its outlet port. Absence of these downward pitches will result in

probable water hammer and premature heat exchanger fracture and leakage.

The heat exchanger coils are designed to operate with dry steam only. The presence of condensate in the steam will cause water hammer and subsequent heaL exchanger

failure. The steam supply connection must be taken from the top of a well dripped

steam main. If the supply run-out to the dryer exceeds twenty feet, it should be dripped just before the control valve with a proper trap and a dirt pocket. (See Figure 1)

Proper trap selection is mandatory. For low pressure units (15 psi or less) use

an F & T (float and thermostatic) trap. For pressures above 15 psi up to 125 psi use bucket (inverted bucket) traps. DO NOT EXCEED 125 psi. Do not use thermo

dynamic, disc, or impulse traps.

Condensate disposal is important. Do not elevate the condensate return line

after an F & T trap. Drain only by gravity into a properly-vented low pressure

return or condensate tank. A condensate line may be elevated after a bucket trap

only if there is sufficient pressure to overcome the head. Determine steam

pressure after deducting 12 psi for the control valve, coil, and trap losses.

(Each foot of elevation requires 1/2 pound of remaining pressure.)

Trap location is essential. The trap inlet should be positioned 12" minimum below

coil outlet to assure complete coil drainage.
