1. The controls that operate the belt conveyor and the heaters are located on the front of the unit.
2. A. (NON-EZ MODELS)
1.
The direction of the belt conveyor travel is controlled by a hidden rocker switch located
beneath the left side conveyor extension, behind a removable cover attached to the base
housing panel. To change belt direction, remove this cover, flip the rocker switch to the
opposite setting, and replace the cover. This operation can be performed while the belt is
moving.
4. A. The exterior metal surfaces of the unit will get hot enough to
cause burns. Avoid touching these surfaces to prevent injury.
B. (top heaters). The white ceramic
heaters located in the top of the unit operate at very high temperatures.
5. Two adjustable deflector shields are located at the inlet/outlet of the unit, above the conveyor belt.
These shields are designed to keep maximum heat inside the unit. Position the shields as needed
for product flow.
6. This oven has 3 heating zones, 2 on top, and a bottom one. The 2 top zones share the same
parameters (set point, probe offsets, etc.) The bottom zone is completely independent of the top
one.
The On/Off switch is used to turn the unit on or off. Once the unit is turned on the
conveyor will automatically run. Warning: Ensure no hands, tools or parts are
located on the conveyor as injury will result when unit is turned on.
2. The control display (oval keypad) is used to control top and bottom heat only. The control
settings allow for separate upper and lower zone control. The settings for upper and lower
zones are 1 through 15; 1 being coolest and 15 being hottest setting. (See control operation

o In normal use, if temperature ever goes above (set point + threshold), High Temperature
Error is immediately triggered.
o If set point is changed (lowered) by the user, the unit will look at the current temperature for 2
minutes and display HI. The peak temperature reached during this time is recorded.
o Thereafter, unit monitors the temperature until it reaches set point. During this cooldown
time, standard HI message is still displayed. User may change set point again, but 2-minute
timer is restarted (and old Peak value still applies.)
· During the cooldown time, if ever the temperature rises the previously recorded peak
temperature, High Temperature Error is triggered.
· Once set point is reached, rdy is displayed again.
· HI is displayed only if other zone is rdy or also HI. If other zone is Lo, then LH (low-high) is displayed
instead of HI.

This Mode alerts the operator to situations that the controller has detected as faulty operation that
needs attention.
An starts beeping loudly when such a situation is detected. the I/0 button to
the . The alarm condition still exists, the ALARM status light continues to flash, but the
buzzer is cancelled.
Alarm conditions are in two (2) categories: (a) Temperature Probe Failure; (b) Overheat Conditions.
a. Temperature Probe Failure.
Whenever any of the three temperature probes fail (2-top, 1-bottom), the controller alerts the
operator (loud buzzer beeping). Only when the alarm condition has been fixed will the
buzzer not sound when the unit is turned ON via the I/0 button.
The controller automatically responds to such conditions, depending on which type of failure
has occurred. Responses are as follows:
1. Scrolling message on the display:
2. The affected zone status light flashes.
3. If either of the Top probes has failed, the controller continues to regulate top heat as if
nothing had happened. This is because each probe is a redundant item for the other. With
one probe input invalid, the controller reads the other input as valid.
4. If both Top probes should fail, the controller reverts to a preset “duty cycle” program that
allows a reduced amount of top heat to be generated. Since there is no reliable top probe
input, the controller controls power to the heaters on an percentage basis, such
as 66% time , 33% time . This is done to prevent a possible “Overheat” condition,
since there is now no reliable means to sense an Top overheat condition.

Anormal operator response may be as such:
1. the I/0 button to the buzzer.
2. The scrolling message goes away.
3. The status light stays illuminated.
4. All other functions continue as normal:
a. Display shows current recipe selection. Recipe selection is still possible.
b. Belt moves and belt status light is illuminated.
c. Heat Zone status lights will be dark.
5. If the button is pressed to view current temperatures, the unaffected zones will
display their current temperature, but the affected zone(s) will scroll the
message, without any beeping buzzer.
b. Overheat Conditions.
Overheat conditions result from excessive power being applied to the heaters. Such situations
usually arise from a solid-state relay that has failed , of which there is one for each heat
zone (three total). However, over-voltage conditions can also cause excess heat, even though
the relays are OK. Therefore, it is necessary to properly trouble-shoot such conditions to
correctly identify the problem.
The maximum allowable temperature is programmable in the
Mode, and is factory set at 1100°F (593°C).
The controller automatically responds to such conditions as follows:
1. Scrolling message on the display:
2. Alarm status light is illuminated.
3. By shutting power to heaters until Overheat condition resolved.
Anormal operator response may be as such:
1. the I/0 button to the buzzer.
2. The scrolling message goes away.
3. The status light stays illuminated.
4. All other functions continue as normal:
a. Display shows current recipe. Recipe selection is still possible.
b. Belt moves and belt status light is illuminated.
c. Heat Zone status lights will be dark.
5. If the button is pressed to view current temperatures, the unaffected
zones will display their current temperatures, but the affected zone(s) will scroll the
message, without any beeping buzzer. (Since there is no power going
to the heaters, the temperatures should be lower than normal, a failed
relay is continuing to power the heater(s).
