1.1.7 Nozzle Check Function
This function checks the production program to confirm that the
appropriate nozzle is installed in each holder. This is done by
performing a check on the nozzle diameter and the background
disk diameter.
If a program has been transmitted to the foreground, then once
program changeover has been completed.the Nozzle Check
function is carried out when automatic operation begins. However,
if the nozzles installed in the previous production program have
the same nozzle diameter and background disk diameter as the
nozzles set to be used in the current production program then no
check is performed. If either the nozzle diameter or the
background disk diameter are different then a check is performed.
It is necessary to set Proper data for this function to work. Make
the setting in the following manner:
Proper
124. Nozzle Check SW: This Proper data function sets
whether or not the function will be
performed. Set it to YES or NO.
When the Nozzle Check function is operative a display like the one
below will appear.
SET: Press this key to set the selected nozzle.

1.2 Automatic and Step Operation
There are two operation modes: Automatic and Step. The differences
between the two are explained below.
1.2.1 Automatic Operation
In automatic operation, the machine operates continuously without
stopping between each sequence. When the last board has been fed
out, the machine will suspend operation but will automatically
resume when a new board is loaded. Under the following
conditions, the machine will stop and exit automatic operation.
• The [CYCLE STOP] button has been pressed.
• The production schedule has been set to one board, and
sequences for that board are completed.
• There are no parts, or an error has occurred in automatic
recovery mode.
• There are no parts, or an error has occurred in placing (error
stop mode).
• The nozzle skip function is being used, and the number of
disabled nozzles has exceeded the preset limit.
• Large parts are not being picked up.
• An emergency alarm has occurred.
• The calculation of data necessary for placing parts does not
finish in time.
• Vision processing does not finish in time.
1.2.2 Step Operation
The machine operates one sequence at a time.
After every sequence, the message "Press START" appears. After
the last sequence the board is removed from the XY table and the
message "Press START" appears. During production, when there is
no board on the XY table, a board is loaded, and after one sequence,
the message "Press START" appears. In all other aspects the
machine operates as if it were in automatic operation mode.

1.3 Recovery
When a part cannot be picked, or when a part is judged to be defective,
the same type of part is picked up again at the next opportunity. This is
called recovery. Recovery mode can be set in MCS/2H Status data or at
the machine by pressing [SET], [STATUS], [RECOVERY] and [CHANGE].
There are three types of recovery modes: auto recovery, error stop and
error pass, each of which is explained below.
1.3.1 Operation of Each Recovery Mode
A. Auto Recovery
If a part is rejected during inspection or if the part is not picked,
the device number is recorded in the error recovery counter,
and the recovery operation is automatically carried out. When
the error recovery counter exceeds a preset number, the
machine stops. For example, if the counter is set at two, the
machine will stop when a part on the same device number is
mispicked three times. After this, if the [START] button is
pressed again, the recovery operation will be carried out again.
The error recovery counter number can be set either through
MCS/2H or by pressing [SET], [STATUS], [RECOVERY] and
[TIMES].
• Error Recovery Counter
Each device number is registered in the counter, and every
error is registered and sorted by device number. Each error
increases the counter by one. If a part is determined as good
this counter is cleared. However, when the number of part
errors or missing parts for any given device number exceeds a
preset number the machine stops.
After the error recovery counter exceeds its preset number the
machine stops when the defective part reaches station 5. If
before this point a part is picked from the same device number
and is held between Stations 1 and 4, those parts will not
register on the error counter. Therefore, when the machine is
resupplied and started again, the errors that occurred before
resupplying will not cause the machine to stop again.
