7. Operating the unit
7.1. Normal operation
1. Turn on mains switch 6. The fans will start and the control panel display will light up showing
either the manufacturer’s settings or the setting last used.
2. Select the appropriate heating zones by pressing one or more of the lamp zone selection
switches. The LED's indicate when a zone has been selected.
3. The level at which the unit operates can be set between 1 and 10 by using the ‘+’ or ‘-’
‘POWER/TEMP1’ switches. Between the flash operations the unit returns to the normal standby
level awaiting the next input signal. The unit also has another unique feature in that after a
predetermined number of minutes during which time no input signal is received the unit will
switch to a low standby level to avoid overheating the pallets and this time can also be set by the
user. For information regarding the setting of these levels please refer to the programming
instructions on Page 9.
4. Dependent upon the last used mode either lamp ‘AUT’ (automatic) or lamp ‘MAN’ (manual)
will light. To change the mode press the ‘FUNCTION’ switch.
5. The ‘TIME/TEMP2’ display shows the time in tenths of a second from 0.0 to 9.9 and in seconds
from 10 to 99. To change the indicated time press either ‘+’ or ‘-’. Keeping either switch
pressed results in an increasingly rapid change of the display.
6. The power level and the drying time can also be adjusted while the flash cure is in operation. To
alter the settings simply press the ‘+’ or ‘-’ membrane switches which are located below each
display. The power and time displays will start to pulse and pressing the ‘+’ or ‘-’ switch will
change the appropriate display. The new setting will take effect from the start of the next cycle.
7. When the automatic mode lamp is burning, the unit is controlled by input signals through the
connection socket on the rear of the machine.
8. When the start signal is given by either the printing machine or external switch e.g. footswitch
or photocell the unit will switch on and the Input lamp will light. When the ‘TIME’ display has
counted down to zero the ‘OUTPUT ‘lamp will light and the dryer will give a ready signal to
the carousel and the time display will change to the pre-set time.
9. Using the function switch to select the ‘MAN’ mode the unit can then be operated by using the
‘TEST’ switch on the control panel.
Pressing the ‘TEST’ switch at any time while the unit is operating in either the
‘AUT’ or ‘MAN’ mode will stop the countdown and return the unit to the
normal standby state.
Operating Instruction MHM Flash Cures
Operating instructions MHM Flash Cures.docx Page 13 of 17
7.2. Overheat protection
When the temperature inside the unit rises above 70 °Celsius, the unit switches off automatically to
protect the electronics. In this case, the temperature inside the controller will be shown in the
‘POWER/TEMP1’ display. While the unit cools down, make sure that the fans are working and the
cover grill is not obstructed. Should the unit require cleaning, switch off and unplug the power cord.
When the unit has cooled down it may be restarted using the ‘TEST’ switch, which will return the
unit to the standby position.
7.3. Programming the Flash Cure
The unit as delivered has the normal standby and maximum heat output levels as well as a low
standby level and the time before this low level is activated pre-set.
The user may change any or all of these settings as follows:
Press and hold ‘FUNCTION’ button until display changes - approximately 5 seconds.
This set up program may be interrupted and the unit returned to normal operating mode at any time
by pressing the ‘TEST’ button.
The manufacturer’s settings are:
[S-d] [000] [P-H] [099] [P-L] [020] [P-d] [003] [d-d] [002]
As soon as an input signal is received the unit will operate normally irrespective of whether it is in
the normal or low level standby position.
While the unit is in the low level standby position the displays will display [PPP] and [ddd].
Do not cover or obstruct the fans. This may result in loss of efficiency or reduction
of lifetime.
Do not touch the lamps or reflector while the unit is in use or before it has cooled
down after switching off.
To switch off the low level standby setting the [d-d] time should be set to [000].
