1. Before operation
The following explains how to cancel emergency stop and clear errors. Read before operating the
machine.
█
Cautions during machine operation
• Do not turn off the compressed air during operation. The machine may malfunction, as pneumatic
devices are not correctly controlled.
• Before beginning maintenance, switch off the air-supply as needed. Before that, if there is the
residual pressure releasing valve, make sure to open it to release the residual pressure.
█
Cautions during power outages
If a power outage (blackout) occurs during automatic machine operation, always turn the main power
switch off to prevent faulty operation or machine damage after power has been restored. Also remove
the boards that remain in the machine.

Head or nozzle-related errors
Code Error name and description
Ea00097
NOZZLE RECOGNITION ERROR
State
Intensity of Component pole is not enough at threshold level. Nozzle is recognized as a component. Please
check nozzle and clean it.
Cause
Component electrode brightness did not reach the brightness ("Comp. Intensity" parameter setting) that can
be identified as a component. A nozzle might have been misrecognized as a component.
Action Check the nozzle that caused the error and clean it. Adjust the "Comp. Intensity" parameter in parts data.
Ea00204
NOZZLE STATION ERROR
State There is no nozzle present for the next sequence. Please check nozzle station data.
Cause Nozzles to be used are not specified in nozzle station information.
Action Check the settings in nozzle station information.
Ea00864
INTERLOCK ERROR
State
You can't move X ,Y ,R or W axis, because Z axis is moving or Z axis position safety sensor is OFF. Please
check Z axis position.
Cause Head is lowered or sensor is defective.
Action Raise the head (Z-axis) by hand.
Ea00865
INTERLOCK ERROR
State You can't move X or Y axis, because there isn't a nozzle station at the bottom.
Cause Nozzle station is raised, or the lower end sensor in the nozzle station does not work.
Action
Lower the nozzle station in manual mode. With the nozzle station lowered, check I/O monitor to see if the
sensor is working. If not, replace the sensor.
Ea00880
<<WARNING VACUUM LEVEL ERROR>
MOUNT IO SEQUENCE VACUUM LEVEL ERROR
State
Vacuum level has not reached the specified level. Please check the nozzle and valve condition. This may
cause bring-back cmp. or double mount problem.
Cause
Negative pressure was insufficient during component placement. A nozzle might have brought a component
back without placing it on the board.
Action Open the [Unit] – [Head] tab and immediately check the nozzles and valves.
Ea02652
INTERLOCK ERROR
State You can't move X ,Y ,R or W axis, because Z axis is not in safe position. Please check Z axis position.
Cause The head position is at a dangerous height, so the X, Y, R and W axes cannot move.
Action Raise the head to a safe height. If the machine's head has a lower end sensor, then check the sensor status.
Ea02653
INTERLOCK ERROR
State Z axis is not in a safe position. Please check Z axis position.
Cause The head position is at a dangerous height right after return-to-origin is performed.
Action Check that the current head position (Z-axis) is lowered to a dangerous height.
