#2: RUNNING THE FLASH CURE IN INTERNAL MODE
With the MHM main computer set for Flash Internal Mode, program the desired flash time.
When the first platen programmed to flash moves under the flash cure unit it will flash for the
Time programmed and another cycle will begin.
In this mode, the temperature sensor module will still shut the flash unit off at the programmed
temperature “set
-
point”. It may be necessary to raise the temperature controller’s “set
-
point” to
a slightly higher setting.
This may or may not be required and your experience will guide you through this decision.
#3: RUNNING THE FLASH WITH AN EXTERNAL SENSOR
The dwell timer should be set to “D” mode and the desired flash time must be set on the dwell
timer.
The temperature controller will still turn the flash unit off when the substrate reaches the
temperature set on the temp controller. In this mode, you may find it helpful to raise the “set
-
point” of the controller.
The Following information does not apply to the newer Controllers, these cannot be
taken out of “RUN “ mode.
If you have a older version of the controller and it is taken out of “RUN”
mode follow instructions below.
#4 - CAUTION:
Be aware that by changing the “set
-
point” there is a
chance that the temp control
module may have been taken out of run mode if you accidentally hit one of the arrow keys while
exiting the menu.
If you do not have the word “RUN” lighted in red on the left side of the temperature control
module, then you may have accidentally changed a setting.
(You must have the control module set to show the word “RUN” in red to operate in external
mode and use the temperature control feature. If not in “RUN” mode the machine will only run
one cycle and an error will appear on the machine’s
computer.)
With the temperature control module displaying the digits of the current temperature STEADY ON
and NOT FLASHING, follow these steps to correct the setting:
-
Press the “P” button 3 times. After the 3
rd
time, the contro
ller will be flashing “RUN –
NO
–
RUN
–
NO”
-
Change the flash setting sequence to “RUN –
YES
–
RUN
–
YES” by pressing the down arrow 1 time.
Now the controller display will begin to flash “RUN –
YES
–
RUN
–
YES”.
-Press
the “P” button 1 time and the controller will go back to showing the digits of current
temperature (a low reading from the floor or a cold pallet).
The word “RUN” will be lighted in red on the left side of the temperature controller ind
icating
that the module is set to run and the flash unit is ready for production.
