Do not exceed the electrical and temperature ratings printed on
the dataplate of the oven.
WARNING:
Improper operation of the oven could
resuit in dangerous conditions.TOpreclude hazard
and minimize risk, follow all instructionsand operate
within design limits noted on the datapiate.
4.1 Location
Keep line voltage variations to a minimum for best control
accuracy. Do not locateunit in areas of wide ambient
temperature variation, such as near vents or outdoor entrances.
Placeunit atleast onefoot from walls, although more spacemay
be required for ease of maintenance.
WARNING:
For proper operation of the unit and for
safety, make surethat the unit
is level when installed.
Door may swing shut on personnel
if the unit is tilted
and the entire unit may tip when the door
is open.
4.2 Wiring
For detailed wiring information, refer to the wiring diagrams at
the end of this manual.
CAUTION:
Connect the oven to the proper power
source. Failure to use nespecifiedvoltagecan result
in damage to the oven.
All models are supplied with a line cord and electrical plug.
Information for sizing fuse, circuit breaker, or power lines
appears on the oven dataplate and in the general specifications
table (refer to Table
1 on page 1). Fuse protection must never
exceed
125% of oven's current rating.
CAUTION:
For personal safety and trouble-free
operation, this unit must be properly grounded before
it
is used. Always conform to the National Electrical
Code and local codes. Utilize proper grounding
techniques to reduce RFI and EM1 for electronicgear.
Do not connect unit to already overloaded power
lines; lower voltage to unit will decrease power to the
heating elements.
4.3 Exhaust Modifications
Never use an exhaust stack directly between the oven and the
exhaust.
A draft diverter, vacuum breaker, exhausthood, or
similar device (refer to Figure
1) must be connected between the
oven and the exhaust. This connection prevents "chimney effect"
which sucks heat out of the chamber and results in slow run-up
time or poor temperature uniformity.

Figure2. Oven Door Operation
5.2 Intakeand ExhaustVents
The intake vent is located at the top of the right side and the
exhaust vent islocated at the bottom of the right side. For most
applications, vents should be closed during operation of the
oven; closed vents result in more efficient operation and greater
temperature stability. However, there are some applications
which benefit from partially orfully open vents.
Vents should be partially or fully open for the following
application:
To provide operation near ambient temperatures. The oven
may notreliably control temperatures near ambient.Opening
the vents allows sufficient heat loss to permit such operation.
To provide slow cool down of work load. Somework loads
may bedamaged by heat shock when the oven door is
opened. Vents can be opened to allow work load to cool
gradually.
To provide removal of vapors which result from the heating
process. Most drying operations that release vapors are best
performed with vents partially opened to prevent the
accumulation of solid by-products.
WARNING: Workload removed from the chamber
aswell asall chamber surfaces, shelves, door
surfaces (insideand out), door throat area, intake and
exhaust ports, and all items of this nature may be vety
hot. To prevent severe burns, exercise extreme care
at all times to avoid contact with hot surfaces.
Solid materials going into the chamber may become
liquid at high temperature. Handle these liquidswith
care. Do not spill high temperature liquids on the
bottom of the oven. Leakage intothe element
compartment results in equipment damage.
To minimize heat transfer to the operator, turn the unit
off when loading or unloading.
4. Select the desired alarm setpoint (refer to Section 6 on
page
5).
5. Press A or 7 until thedesired setpointshows on the bottom
line of the display. Refer to Section

MechanicalConvection Ovens Operation
- UP1 50 Controller
6.2 Basic Operation
To operate the UP150 controller, you must first enter a program.
Once the program isentered into the controller, press the "arrow
down" key to run it. Once the program is running, it can be
placed in "hold mode" to maintain the current setpoint. Also, a
"program advance" can be executed to step the program rapidly
through program segments.
6.3 Entering Program Parameters
To access programming mode:
1.Press the SETIENT key for 3 seconds. Make sure the RUN
light isnot lit at this time.
2. "CtL" will bedisplayedin the upper display with "Pid" in the
lower display. Press the SETENTkey repeatedly (7 times)
until LoC is displayed.
3. Press the "arrow down" once to display "-1" in the lower
display.
4. Press the SETIENT key 4 times until Pffi is displayed.
5. Again, press the "arrow down" once to display "-1" in the
lower display.
6.Press the SETIENT key once. Now the programming mode
is accessed.
Prior to entering the actualprogram steps,you will be prompted
for event type settings. This refers to how a relay will function,
either as a "time event" or a "process variable (alarm) event".
To enter a program in program mode:
1.With "EVl" in the upper display and
"0" in the lowerdisplay,
press the SETIENT key.
2. Next, "AL1" appears in the upper display. A value of
"1" in
the lower display configuresthe alarm as a high temperature
alarm which is the factory setting. (For more information see
"PV Event (alarm) Function List" in the UP150 Instruction
Manual).
3.The alarm feature may or may not have been utilized,
depending on model. If the alarm feature has been utilized
and the alarm actuates, it will remove electrical power to the
heating elements. If the alarm feature has not been utilized,
setting the alarm will not change unit operation. In either
case, the AL1lightwill illuminate duringan alarm condition.
4. Press the SETlENT key to advance to the Alarm 1 value
(Al). This is the temperature at which the alarm will trip.
This is typically setfor 10"higher than the highest setpoint in
the program.
- Use the arrow upldown keys to enter the
Alarm 1value. Notice that the decimal point will flash
indicating a change has been made. You must press the
SETENTkey to register a change.
5.Pressthe SETlENT key to advance to the Alarm 1Hysteresis
setting. Enter 1.0.Press the SETIENT key to advance past
the EV2 and AL2settings to the SSP(starting setpoint) value
and enter the setting from the Program Pattern Setting Table.
6.
? From this point, you will be prompted for SP1 (setpoint I),
tM1 (time I), SP2 - tM2, SP3 - tM3. .. etc. until all the
program parameters have been entered. Note that Time is
enteredinhours andminutes,forexample, 1.45equals 1hour
and 45 minutes.
7.The controller will accept up to 16setpoints and times. If
fewer than 16are required, enter "OFF" as a time value. This
tells the controller you are finished.
WARNING! Do not enter a setpoint into your
program beyond the maximum operating temperature
of your unit.
8. Next, you will be prompted for a Junction Code (JC). This
determines how the controller will function at the end of the
program. Three Junction Code values are available: "0" will
cause the controller to shut-off its outputs at the end of the
program. This is called the "reset" mode. "1" will place the
controller in "Hold" mode.
"2" will cause the program to
repeat continuously.
9. Next you will be prompted for a Wait Zone (WTZ). This is
similar to "guaranteed soak". The factory setting is "OFF"
which means "not used". A wait zone causes the controller
to stop the program clock
if, at the transition from a ramp
segment to a soak segment, the actual chamber temperature
(PV) is not close enough to the setpoint. Assume the
controller is programmed to ramp from 25°C to 100°Cin 1
minute. Since theunit does not have the capability to heat-up
this quickly, the controller will change the setpoint from 25"
to 100"in 1minute and wait atbeginning of the 100"
segmentfor the unit to catch upwith the setpointbefore
continuing the program. Theprogram will continue when the
unit temperature (PV) falls within the specified Wait Zone.
The minimum value of the Wait Zone is 1% of the
controller's span for a given input type. In this example, the
span isfrom -200" to 1000°(1200" x 1%
= 12"). This
means, in the above example, the controller will continue the
program when the unit temperaturereaches 88" (100"
- 12" =
88").
10.The program is now complete and ready to run. Exit the
program parameter setting mode by pressing and holding the
SET/ENT key for 3 seconds.
6.4 Running the Program
To run theprogram, press the Run or "arrow down" key until the
RUN light illuminates.
6.5 Usingthe Hold Function
To hold a running program:
1.Press and hold the SETENTkey for 3 seconds."HoLd" will
appear in the upper display.
2. Press the "arrow up" key so that "on" with flashing decimal
appears in the lower display.
3. Press the SETENTkey to accept.
4. Press and hold the SETlENT key again to return to the
normal display.
To exit the hold mode:
Press and hold the SETIENTkey for3 seconds. "HoLd" will
appear in the upper display. Press the "arrow down" key so that
"OFF" with flashingdecimal appears in the lower display. Press
the SETlENTkey to accept. Press and hold the SETENTkey
again to return to the normal display.
