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

8
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.

9
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
All accessories described in Section 2.6 including article numbers can be found in Section 9.2
Accessories or on the website at:

3Function, set-up and commissioning
3.1 Description of function
•The ACS 921 is a cleaning device that is primarily intended for use with watch parts.
•The ACS 921 has six process positions which are distributed every 60° on a turntable.
•Five cleaning baths, one with ultrasound function and one drying position.
•The watch parts are fitted into the matching plastic or metal baskets.
(for details of original accessories, see Section 9.2).
•The baskets can then be inserted into the basket holder provided for this purpose.
•After this, the basket holder is snapped into the operating position by means of a bayonet lock.
•Next, select the desired programme on the display and press the start button.
•The handling of the cleaning baths and their fluids and the creation of programmes are described in
more detail in Section 4 Operation.
3.2 Setting up
•Remove the ACS 921 and the accessories supplied from their packaging and position them at the desig-
nated set-up location.
Due to the weight of the device, this must be done by two people!
•Keep the packaging for any returns in case repairs are required.
•The outlet opening of the venting fan (top) must not be covered.
•If the installation room cannot be sufficiently ventilated or cannot be ventilated at all, we recommend
using an activated carbon filter, which can be ordered as an accessory. It is also possible to connect an
exhaust air hose with a connecting piece (accessory). (see Section 2.6)
In any case, room ventilation is very important and it is the responsibility of the operator of
the ACS 921 to ensure people are protected!
•The inlet opening of the heater fan (rear) must not be covered.
•Remove the packaging material from the ACS 921.
•Check the ACS 921 and accessories for completeness. (other accessories can be ordered through Cus-
tomer Service)
•Connect the ACS 921 to the mains using the connection cable supplied.
Please note the power input specifications!

12
3.3 Commissioning
Switch on the ACS 921 using the power switch at the bottom rear (on the rear wall of the device).
The ACS 921 now performs an initialisation process:
1. The interior of the device is ventilated. The following appears on the display: VENTING PROCESS
2. The spin motor is initialised. The following appears on the display: SPIN MOTOR INITIALISATION
3. The lift motor is initialised. The following appears on the display: LIFTMOTOR INITIALISATION
4. The turntable is initialized. The following appears on the display: TURNTABLE INITIALISATION
This initialisation process is performed when the ACS 921 is switched on via the mains switch.
Doors may not be opened or left open during the initialisation process.
If the ACS 921 is started with the open door, the message OPEN DOOR appears on the display.
The process is not continued until the door is closed again.
The ACS 921 is now ready to start.
After a certain time (adjustable), the ACS 921 goes into standby mode:
The next time the device is started from standby mode by touching the touch screen, only the VENTING PROCESS
is carried out.
The device is then ready to start again.
Before starting a cleaning programme, the device checks the door can be securely closed.
In order to confirm the process, the door has to be opened and closed again.
Only once this safety check has been carried out can the relevant cleaning programme be
started by pressing the start button again.

3.4 Insert the liquid container and position the turntable
3.4.1 Inserting the liquid container
Proceed as for changing the bath according to Section 4.3.9
Please note: Before inserting the containers, check that they are filled correctly.
Please note: During insertion, so that no fluid is drained.
Important! Bath 1 is always the ultrasound bath and may only be fitted with the relevant container.
Position 1 without container Position 1 with container (ultrasound bath)
Baths 2 to 5 are cleaning baths or rinsing baths. Here, too, only use the original glasses provided for the pur-
pose.

6. The exact position can now be checked again and readjusted if necessary.
7. If the position is OK, it still has to be saved by pressing NEXT STEP
8. The positioning process is now complete
3.5 Inserting baskets
1. Lift the spin flange cover (Figure 1)
2. Snap the basket holder into place at three points with the bayonet fastener (Fig. 2+3)
To do this, push the basket holder upwards and turn it anticlockwise.
3. Release the basket holder in the snap-in position – the process is now complete.
