1.1 Robotic functions
The loading hatch is placed in the centrifuge lid. The hatch is opened by a motor.
The rotor is positioned and hold under the hatch.
1.2 Operating modes
1.2.1 Normal robotic operation
The key-operated switch (Key-Lock) has to be in position LOCK 2 (right key position, turn clockwise).
The key must be pulled off.
Additionally in the complete arrangement the centrifuge has to be protected against unauthorized penetration and
manipulation.
1.2.2 Adjusting / teaching operation and handling of the centrifuge without serial interface
It is only allowed for skilled maintenance staff to work in the adjusting and initializing operation.
After the adjusting and initializing operation the key-operated switch has to be in position LOCK 2
(right key position) and the key must be pulled off.
To protect the key against unauthorized access keep it in a save place.
- Teaching of position 1
Please refer to the operation instruction chapter 30 “Setting rotor position 1”
- Close and open the hatch by the hatch motor drive
Only possible in key-operated switch position TEACH (left key position, the display shows "TEACH").
OPEN the hatch Press key
CLOSE the hatch Press
RPM
key
Notice: The hatch drive acts as long as the key is pressed.
The functions of the following keys are depending to key-operated switch position.
- STOP-key
The
OPEN / STOP
(Generation 1
STOP
) key on the control panel is always active.
- START-key
The
START
key on the control panel is normally active.
But the key function can be blocked / locked via the PC with the command LOCK 5
(see Parameter 00520 or 00633 / 00635).

2 Communication with Hettich centrifuges
2.1 Definition:
"Generation 2" is the updated communication for ROTANTA 460 ROBOTIC type 5680
"Generation 1" is the original communication for ROTANTA 46 RSC Robotic type 4815 / 4816 / 4817
The centrifuges of "Generation 2" (ROTANTA 460 ROBOTIC type 5680) accept mostly the original communication
according to the definitions of "Generation 1".
Please find a more detailed description in chapter 4 and 5

PC
Centrifuge
The reaction time of the centrifuge depends on the respective working order.
A busy centrifuge, e.g. during a centrifugation or positioning, uses more computing time and so the reaction time is
up to 150 ms. If there is no answer from the centrifuge after 150 ms, it can be assumed that there is a serial Error.
In case of an error the telegram should be repeated 2 times.
That means: If there is still no answer after the third transmission attempt, the telegram has to be cancelled to
examine the cause of the error.
2.3.3 Rhythm of request
We suggest the following communication timing:
During centrifugation: Parameter 00634
During positioning: Parameter 00634 once per second and parameter 00640 (Generation 1) or parameter 00528
(Generation 2) twice per second. Please refer also to chapter 2.11.5 "Query of actual values"

2.5 Address of the Centrifuge / Change the address
Each centrifuge that is being communicated with must have its own address.
The PC uses this address to communicate with the centrifuge.
This serial address can be compared with the name of a person.
Each address in a system can only be given ONCE. The Hettich-BUS system manages up to 29 centrifuges.
Address range:
1. Address A = 41hex
2. Address B = 42hex
to
26. Address Z = 5Ahex
and
27. Address [ = 5Bhex
28. Address \ = 5Chex
29. Address ] = 5Dhex Default address
Default address / factory settings address is ‘]’ = 29.
Change the address of the centrifuge using the control panel
• Keep the
PROG
key held down for 8 seconds.
After 8 seconds,  Machine Menu  appears in the display.
• Press the
PROG
- key as often as necessary until the ->Settings is displayed.
• Press the
START
- key , the
PROG
- key as often as necessary until the ->PC Address = ] is displayed .
• Use the adjusting knob to setup the desired PC Address .
• Press the
START
- key, Store Settings … and then ->Settings is displayed .
• Press the
OPEN / STOP
(Generation 1
STOP
) - key twice to leave the *** Machine Menu ***.
2.6 Principle for serial communication
The PC requires an available RS 232 interface.
The key-operated switch has to be in position LOCK 2 (right key position).
The centrifuge accept commands from PC only in position LOCK 2
Centrifuges are terminals (slaves) and answer only if they receive an ENQURIY - or SELECT - telegram.
2.6.1 Detection of the “Generation 2”
Send an ENQUIRY telegram with address”$” to parameter 00600 (centrifuge identification).
The robotic centrifuge of Generation 1 (type 4815 to 4817 will return: [ADR] : NAK
The robotic centrifuge of Generation 2 (type 5680) will return “1234”
Please refer to chapter 2.10, parameter 00600
Example (Centrifuge with default address “]” is connected:
PC EOT $ 0 0 6 0 0 ENQ
Cent ] STX 0 0 6 0 0 = 1 2 3 4 ETX DC
Please refer to chapter 2.8, "Parameter-No.: 00600"

EN
10/70
2.6.2 General information for positioning and hatch commands:
The centrifuge acknowledges the transmission of the command with "ACK" when a positioning or hatch
command was sent and executes the command.
Important information for the positioning:
Centrifuges of “Generation 2” (software 01.xx):
During the executing of a positioning command (the rotor moves) ALL OTHER positioning
commands will be ignored.
The centrifuge will acknowledge the additional positioning commands with ACK but the command
will be ignored. The centrifuge does not execute the second command during processing of the first
command). The additional commands will be flushed.
Therefore please wait with the next positioning command until the ongoing positioning is finished.
Centrifuges of “Generation 1” (software 4.xxx):
During the executing of a positioning command (the rotor moves) the ongoing positioning will
immediately be cancelled and the last sent positioning command will be executed.
You can use
• parameter 00640 to handle position 1, 2 3 and 4 with 2-place or 4-place rotors
(using the protocol of "Generation 1"),
• parameter 00524 and 00526 to handle ALL positions with ALL rotors
(using the protocol of "Generation 2").
Time-out:
Each rotor position (1 ... 48) is fixed (held in position) for maximum 20 minutes.
After 20 minutes the fixed position (electronical positioning and the electromagnetic brake) is automatically
deactivated. If the position is needed again please send the command for this position again.
Software-Lock via serial interface
To avoid complications with START commands (by pressing the START-key at the control panel), the software
provide the feature LOCK 5. Then the
START
- key is locked, only the
OPEN / STOP
(Generation 1
STOP
) -key is
active.
Please refer to chapter 2.10.1 (Parameter-No.: 00520) and chapter 2.10.2 (Parameter-No.: 00633)
2.7 General format of parameter content ( V = VAL = Value )
V V V V
MSD LSD MSD LSD
Lowbyte = LSB
Highbyte = MSB
Bit 3...0 3...0 3...0 3...0 = 4 digit
Bit 7....... ........0 7...... .........0 = 2 byte
Bit 15...........................................0 = 1 word
Explanation: MSD/LSD: Most/Least significant Digit (Digit = Nibble = half byte)
MSB/LSB: Most/Least significant Byte
MSb/LSb: Most/Least significant Bit
Values are sent or received in principle as 4 –digit characters.
Each digit has a range: from 30 hex = ‘0’ to 39 hex = ‘9’
and from 41 hex = ‘A’ to 46 hex = ‘F’.
The information (VAL) of one parameter can cover the range 0000 hex to FFFF hex
(0 up to 65535) with one transmission.

In chapter 3 is a cookbook, in chapter 3.7 are examples, where the most important commands and inquiries are
presented:
• START and STOP
• Open and close the hatch
• Move rotor to position X
48 positions are possible, the permitted positions are depending to the installed rotor
• Call up already stored programs

EN
14/70
2.9.2 Parameter 00526 (control commands for positioning and hatch)
Lowbyte: Positioning command
01h: move to position slow ,
02h: move to position fast ,
40h: cancel positioning (i.e. if the positioning fails, the current positioning should be deactivated or
the current positioning is disabled with "timeout")
60h: open hatch
70h: close hatch
80h: terminate positioning
The positioning mode will be terminated automatically
(like the command 00526 = 0080) by:
− closing of the hatch
− switching the key-switch from LOCK 2 to LOCK 3
− switching the key-switch from LOCK 2 to LOCK 1 (TEACH-mode)
− starting the centrifugation
2.9.3 Parameter 00528 (information about positioning and hatch state)
Highbyte: General settings (bit 7) hatch state (bit 0 to 6)
7 1 = magnetic brake implemented
6 1 = hatch timeout (pos error 42 is set )
5 1 = hatch open

• START
Requirement: Key-switch is in position Lock 2
SELECT-Command: 00521 = 0002 (start centrifugation).
• STOP
SELECT-Command: 00521 = 0001 (stop centrifugation).
2.9.5 Special functions: ACK, NAK and SIOF
• If a centrifuge is answering with NAK to a telegram, the SIOF parameter (00685) has to read –out. The enclosed
Info-bit will be reset with the read-out of the parameter.
• Only with deleted bits in SIOF, the centrifuge will accept an order by SELECT.
• SIOF-Bits will be set:
• after "switch on" the centrifuge (mains reset)
• by ENQUIRY a non existent parameter
• by SELECT a non existent parameter
• by SELECT a "read only" parameter
• by SELECT non valid values
• With read-out SIOF ENQUIRY-Telegram to parameter 00685):
• a SIO - error can be detected.
• enables serial interface for SELECT-telegrams.
• with SIOF-enquiry all SIOF-Error-bit will be reset by the centrifuge.

2.10 Detailed description of the parameters
Used abbreviations:
Gen. 1 Generation 1: Machines of family
ROTANTA 46 RSC (Types 4815, 4816 and 4817)
The parameter is possible for the “old” families.
Gen. 2 Generation 2: Machines of family
ROTANTA 460 ROBOTIC (Type 5680)
The parameter is only possible for these machines
Gen. 1 + 2 Generation 1 and 2:
The parameter is possible for BOTH families.
ROTANTA 46 RSC AND ROTANTA 460 ROBOTIC
The parameter is 100% compatible.
Gen. (1) + 2 Generation 1 (not to 100%) and Generation 2:
The parameter is subtotal / to 100% compatible.
Please read the detailed description
Access: R Read: Parameter access is “read only”; A SELECT telegram will cause a NAK
Access: W Write: Parameter access is “write only”; An ENQUIRY telegram will cause a NAK
Access: RW ReadWrite: Parameter access is “read” and “write”.
The centrifuge accepts SELECT-telegrams only in Key-Lock position "LOCK 2",
therefore the key-operated switch has to be in position LOCK 2 (right key-position).
ENQUIRY-telegrams are always possible, independent of the Key-Lock position.
