1Device configuration
The auto-sampler AS 21hp (AS 10e) will be used in combination with:
multi N/C 3100 (N3-500 and higher)
multi N/C pharma UV
multi N/C pharma HT
multi N/C UV HS
It communicates by RS 232 interface to the firmware controller of the main unit
(analyzer), which controls its operation. All operations for movements inside the
sampler will be controlled by a firmware controller, which is located on the pcb main
board of the sampler.

1.1 Power supply
The AS 21hp (AS 10e) will be supplied by an external power supply with 24 V DC
(110 to 230 V AC/24 V DC).
On the pcb main board are internal power regulators for process control (firmware
controller) of the AS 21hp (AS 10e).

3Dismounting and reassembling
3.1 Dismounting into the service position
Remove the sampler from the main unit (analyzer).
Lift-up the sampler carousel (sample tray) from the sampler.
Loosen 5 screws on the rear side.
Fig. 10 5 screws at the rear side
Loosen 10 screws on the bottom side.
Fig. 11 10 screws at the bottom

3.2 Exchange of Z-drive
Move the sampler into the service position.
Fig. 17 Unplugging the electrical connector from the main board (exchange of Z-drive)
Unplug the Z-sensor cable (X10) and the Z-motor cable (X6).
Loosen the 2 screws and remove cable holders.

Loosen the 2 screws with an Allen key (1.5 mm) and remove the Z-drive.
The reassembling of the Z-drive will be done in reverse order.
Perform the final test according to chapter 4.
3.3 Exchange of X-drive (carrousel guide)
Move the sampler into the service position.

4Final test of the sampler AS 21hp (AS 10e)
Perform the following test after each service activity (exchange/adjustment/
maintenance):
Self-initialization (see chapter "Self-initialization" p. 19).
Initialization with service program with command <I>.
Tray detection with command <T> (see chapter "Report-Commands" p. 24).
4.1 Self-initialization
Provide the power supply (24 V DC) for the sampler and switch it on.
The sampler starts its self-initialization routine:
−Sampler arm(needles) moves up (Z-drive).
−Sampler arm moves to the sample position.
−Sampler tray(carousel) rotates and determines the carousel size by detecting the
magnets.
The sampler tray rotation is finished and stops at position 1.
