3.2.5 Behaviour of the machine after pressing the emergency stop pushbutton
After pressing the emergency stop pushbutton, the machine behaves as follows:
– All conveyors are disabled
– The preheaters are turned off
– The solder waves are turned off and the axes of the soldering modules disabled
– The spray fluxer is turned off, its axes are disabled
– The exhaust air system remains switched on
Despite this, there are still some residual risks!
DANGER
Risk of death or serious injury due to liquid metal; Risk of injury and material dam-
age due to hot machine parts!
a) Hoods, doors and covers must only be opened by trained, qualified staff after
pressing the emergency stop pushbutton! In this respect, take the following haz-
ards into account:
ð The solder pot heaters are not switched off. Therefore, the solder pots do not
cool off and the solder contained therein remains liquid!
ð The preheaters cool slowly off and may be still dangerously hot!
ð Parts of the conveyor can be very hot; this is particularly true in the preheater
area!

1 Horn: The horn sounds when a message appears for a set period of time.
This function can be disabled.
2 Red: Emergency; dangerous condition, abnormal condition, imminent crit-
ical condition.
3 Orange: Abnormal condition; imminent critical condition.
4 Blue: Mandatory; operator intervention required.
5 Green: Normal condition; wait.

3.2.8 Exhaust air monitoring
5
The exhaust air monitoring (5) unit disables the machine as soon as the air quant-
ity falls below the set value on the switch. Information about the required suction
volume can be found in chapter Technical data [
}25]..
3.2.9 Safety switch
6
Safety switches initiate the interruption of the working processes as soon as an ap-
propriately secured protection device (glass door, safety door) is opened:
Fluxer module:
– If some soldering material is conveyed into the fluxer module, the fluxer con-
veyor continues to run until the soldering material has reached the stopper.
Then, the conveyor is stopped. The soldering material is not fluxed.
– Should the soldering material be fluxed, this working process is immediately
stopped.
Preheating module:
– If some soldering material is conveyed into the preheating module, the pre-
heater conveyor continues to run until the soldering material has reached the
stopper. Then, the conveyor is stopped. The soldering material is not pre-
heated.
– If the soldering material is preheated, the preheater remains active until the
solder material has been completely processed in the preheating module.
Then, the preheater is turned off.
Soldering module:
– If some soldering material is conveyed into the soldering module, the soldering
conveyor continues to run until the soldering material has reached the stopper.
Then, the conveyor is stopped. The soldering material is not soldered. The
solder wave is disabled, the solder pot heating remains on!
– Should the soldering material be soldered, this working process is immediately
stopped. The solder wave is disabled, the solder pot heating remains on!
Despite this, there are still some residual risks!
DANGER
Severe or fatal injury from hot machine! Hot pot containing molten metal!
The entire machine is hot during operation and contains liquid metal! When the safety
doors are opened, the solder pot heating remains on! The preheaters cool slowly off
and may be still dangerously hot!
a) Service on the hot machine may only be carried out by specially trained staff,
qualified for this type of work! For these types of work, a company internal oper-
ating procedure for protective clothing is to be issued!
b) You should always take into account the possibility for metal to spray out!
