Setting the Device Table Mode
There are four modes of operation for the device tables (feeder pallets); Joint, Joint
Resupply, Device Change and Changeover.
Procedure
1. At the [Main] screen, press [Operation] to display the [Operation] screen.
2. Under Table Mode, select from [Joint], [Joint Resupply], [Device Change] or
[Changeover].
3. Press [Close] to enter the settings and return to the [Main] screen.
Joint: Joint mode is suitable for supplying a wide range of parts during
assembly. Both feeder pallets are used during production, and as a
result, up to 140 part types can be loaded on the CP-842E, and up to
80 on the CP-842ME. In this mode, both tables enter the production
area and move to the pick-up position as required.
Joint Resupply: This mode is ideal for use when the device tables are changed fairly
infrequently. Joint Resupply mode is similar to Joint mode, except
only one device table is in the production area for the majority of the
time. The follow-up table (i.e., the table which is currently idle)
remains at its retract position and does not move into the production
area until just before it is needed.
Device Change: This mode is suitable for use during mass production with a fairly
small range of parts (up to CP-842E: 70/ CP-842ME: 40 part types
on each device table). Users can create two identical feeders sets
which automatically switch places when a recovery limit on the table
currently being used is reached. The device table for which the
recovery limit was reached moves to the resupply position.
Changeover: This mode is used to reduce changeover time during small lot
production. While the current table is supplying parts for the current
assembly, the spare table can be loaded with parts for the next job.

Performing a Manual Device Check
Before operation can be commenced it is first necessary to inform the machine that feeders
have been correctly positioned in each of the slots that are used in the production program.
This is performed by carrying out a device check. A device check can be performed
manually or automatically, these procedures are detailed below.
Procedure
1. Press [Device Check] at the [Main] screen. The [Device Check] screen displays.
The [Device Check] screen shows a color coded box for each of the slots on each device
pallet. An explanation of the color coding system is given on the screen itself. As can
be seen, the Parts set status is shown in green, and all the slots/feeders used in the
production program must display in green before production can commence.
2. Check the status of each feeder on the device table and press each once slot to change
the color to green.
It is also possible to use the [Select All] button to change the status of all slots (other
than those not used or not set) to green.
Specifying an Automatic Device Check
Each time the production program is changed or a feeder is replaced, it is possible to make
a setting to display the [Device Check] screen automatically. The user specifies the
conditions that will display [Device Check] screen at the start of automatic operation, and is
notified only when an error is detected that matches the settings.
Procedure
1. Press [Maintenance] at the [Main] screen, and then press [Configuration] - [Basic]. Four

CP-842E / CP-842ME System Reference 53
buttons are displayed in the Forced Device Check Trigger section. The followings are
explanations of each button.
2. Under Forced Device Check Trigger, select the event which will invoke an automatic
device check.
3. Press [Close] to enter the settings and return to the [Basic Configuration] screen.
Specifying the Next Device Trigger
Next devices provide a backup for parts supply, allowing the machine to switch to a fresh
feeder loaded with the same parts, when parts run out. The settings for a next device loop
(starting and ending at one feeder), are made in the production program. Refer to your host
system documentation for details of how to specify a next device loop. The type of event
during assembly which causes the machine to switch from one feeder to the next can be
set at the machine. The following settings are available.
The above setting is also applied to the device change mode when switching from the
original table to the spare table.
Procedure
1. Press [Maintenance] at the [Main] screen, and then press [Configuration] - [Basic
Configuration].
2. Under Next Device Trigger, select the event which will cause the machine to switch to
the next device.
None Automatic operation can be entered even when a device check has not
been performed.
Parts Out The [Device Check] screen displays automatically if a parts out error is
detected.
Pick-up Miss The [Device Check] screen displays automatically if a pick-up or parts
out error is detected.
Vision Error The [Device Check] screen displays automatically if a pick-up error,
inspection error, or parts out error is detected.
Part Data The trigger setting in part data is used.Refer to your host system
documentation for details of how to make this setting.
Parts Out The machine switches to the next device when parts out is detected.
Pick-up Miss The machine switches to the next device if a pick-up or parts out error is
detected.
Vision Error The machine switches to the next device if a pick-up error, inspection
error, or parts out error is detected.
