2.3 Binding instructions
2.4 Emergency stop system
The ACS 921 cleaning device is equipped with an EMERGENCY STOP switch. This is located at the top of the
housing (see arrow).
It is used to quickly bring the mechanical parts of the ACS 921 to a standstill in the event of a hazard or to avert
a hazard.
Pressing EMERGENCY STOP immediately stops any movement of the ACS 921 and interrupts an active process.
The ACS 921 cannot be operated again until the EMERGENCY-STOP switch has been unlocked.
To do this, return the switch to its original position by turning it in the direction of the arrow.
Use eye protection
Use hand protection

An interrupted process does not start automatically (restart protection). The process must be restarted
manually.
2.5 Door monitoring system
The ACS 921 is equipped with a door monitoring system. A sensor installed at the bottom right of the housing
serves this purpose. The control system of the ACS 921 checks the sensor for proper functioning before each
start-up.
If the door is opened during the cleaning process, an active process is stopped immediately and the message
DOORS OPEN appears on the display.
As soon as the door is closed again, the active process continues at the same point.

2.6 Venting system
2.6.1 Device venting
The ACS 921 is equipped with a venting system. This is activated when powering up and starting up (also after
standby mode). This ensures that the interior of the ACS 921 is always vented before the cleaning process be-
gins. The venting system also remains switched on during the cleaning process, thus ensuring safe operation.
Venting outlet on top of device housing
Please note: The room in which the device is used must have a ventilation system.
If this is not the case, the exhaust air must not be fed directly into the room. In this case, Greiner Vibrograf AG
offers the relevant accessories as explained below:
2.6.2 Venting via activated carbon filter
An activated carbon filter (accessory) can be mounted directly on the air outlet using a connection flange.
If an activated carbon filter is used, it must still be activated in the settings. When this is activated, the device
knows when the next filter change is due and sends a message to the user.

10
2.6.3 Venting with hose connection
A hose (nominal diameter 100 mm) can be connected directly by means of a connection flange and a matching
transition piece: this then conducts the exhaust air into the atmosphere through a room opening.
Flexible suction pipe, Ø 100 mm
