4)
Verify correct recipe is loaded.
Verify correct recipe is loaded. If not, click on RECIPE button for “Recipe” screen or enter the zone set
point temperatures and belt speed by clicking on respective the blue fields and typing the correct number.
5)
In Process field, select “WARM UP” to initiate the process selected.
In the “WARM UP” mode, the heating elements will come on. After 10 minutes, check the system for
instability or cycling, and correct if necessary.
While the machine is heating, check for alarms and listen for the alarm buzzer. In particular, check for any
exhaust fan failure alarms. Check for failed elements. The effect of an element failure is generally minimal
unless two failed elements are adjacent to each other.
NOTE: Allow the system to stabilize and to enter the PROCESS READY or PROCESS START
mode as indicated by a green light on the screen before processing any product.
You must be in “Process Off” condition to exit (indicated by a red light).
2.3.1 Power Saving Feature
The actual power number reflects the actual power being used by the machine. This number is based on the
% power applied to the zone and the lamp power of the zone. This number can be limited by the “Maximum
power” value set up in the SCR Calibration screen. If this value is set at 0, no power is calculated and no
limit is set on the power used by the machine. Any non-zero value will cause the system to calculate the
power and limit it to this value.
Default maximum power is set to 50%
NOTE: Edge heaters are not part of the calculation.
The total power will then always stay below the number set by the user.
WARNING: A low power limit may prevent the machine from reaching the Process Ready state,
since the user value may not be high enough to reach the desired temperature. For example,
setting a maximum of 30 kW will most likely not be enough to reach a steady state in a high
temperature furnace when trying to go to 900 degrees C. In this case, the machine will just stay in
the warm-up mode.
2.3.2 Transport
Speed
Move the cursor to the Belt Speed field. Enter the desired transport speed. Vary the conveyor speed from
minimum to maximum, checking for smooth operation at all speeds. To check for belt speed accuracy, set
the speed at its midrange setting. Place a coin or metal ruler on the moving belt and time through two fixed
points while the furnace is in the off or COOL DOWN mode.
