1. Introduction
1.1. DRVRMOTL
Motorized linear and manual rotary drives are designed to operate sample transporters and
optionally attached sample locking mechanisms such as a pincer grip. The DRVRMOTL linear drive is
compatible with RM40, RMD40, RMDG40 and GMD40. For these sample transporters, a variety of
Ferrovac sample receivers, carriers and pincers are available. The motorized linear drive still allows
for manual rotation of the shaft for sensitive application of the rotation of your sample holder or
when opening/closing the pincer. Rotation can be locked using a thumbscrew.
1.2. DRVRMOTLR
Motorized linear and rotary drives are designed to operate sample transporter and optionally
attached sample locking mechanisms such as a pincer grip. The DRVRMOTLR linear and rotary drive
is compatible with RM40, RMD40, RMDG40 and GMD40. For these sample transporters, a variety of
Ferrovac sample receivers, carriers and pincers are available. Single rotation and linear movement is
completely motorized. Thus opening/closing of pincers or rotation of you sample carrier is easily
done from your workstation.
1.3. DRVRMOTLRR
Motorized linear and rotary drives are designed to operate sample transporters and to optionally
attached sample locking mechanisms such as a pincer grip. The DRVRMOTLRR linear and double
rotary drive is only compatible with RMDG40 sample transporters (as only this model has two
rotatable axis). For this sample transporter a variety of Ferrovac sample receivers, carriers and
pincers are available. Double rotational axis and linear movement is completely motorized. Thus
opening/closing and rotation of pincers or rotation of your sample carrier is easily done from your
workstation.
2. Unpacking and Inspection
Motorized sample transporters are shipped clean and ready to use in UHV. Prepare a sufficiently
clean workspace and wear surgical gloves when unpacking and inspecting the device. Check for any
visible damage of the package, manipulator and accessories. Compare the contents of the package
with the delivery note. Any damage or missing items must be reported to Ferrovac within 48 hours
after delivery.

CAUTION!
Always use powder-free examination gloves during unpacking to avoid contamination.
Please ensure enough working space for unpacking and inspection.
Please clean the working table/surface and cover it with Aluminium foil or household foil.
Never hit the knife edge nor the bellows.
Never expose the Sample Transporter to physical shocks (brittle magnets!!!).
Never bend the tube nor the shaft.
3. Overview
The main purpose of RM40, RMD40, RMDG40 and GMD40 sample transporters with motorization is
to transfer samples over longer distances.

The same nomenclature applies to the single rotary motorized DRVRMOTLR.
3.2. Handling & Adjusting Of the Limit Switches
3.2.1. Front Limit Switch
All motorizations for Ferrovac sample transporters have an adjustable limit switch, with which you
can define your max. extended length of the sample transporter. Undo the small screw on the side of
the limit switch housing to adjust it’s position.
The front limit switch of all sample transporter
motorizations (DRVRMOTL, DRVRMOTLR,
DRVRMOTLRR) is connected to pins 9 and 18 on
the 26P D-Sub connector.
The switch is a reed switch, which is operated by an applied magnetic field. This switch is normally
closed wired and opened by the switch action (position is reached).

DRVRM Technical Reference Manual
10/14
May 23 REV B
3.2.2. Rear Limit Switch
You find the rear limit switch at the rear end of the motorization (directly under the spindle unit).
The position of it is not adjustable.
The front limit switch of all sample transporter motorizations
(DRVRMOTL, DRVRMOTLR, DRVRMOTLRR) is connected to pins 8
and 17 on the 26P D-Sub connector.
3.2.3. Rotation Limit Switches
Each rotational unit has two limit switches (start- & end-position). The start- and the angle of the
end-position can easily be adjusted by 3 grub screws (3 screws/position).
Fig. 7; Rot. Limit Switch DRVRMOTLR
For the DRVRMOTL & DRVRMOTLR motorizations, the switches can also be connected as "normal
open". However, it is highly recommended to connect as "normal closed"!
CAUTION: Risk of squashing/crushing!
Never touch the motorized sample transporter during movement!
CAUTION: Risk of squashing/crushing!
Never touch the motorized sample transporter during movement!

Please pay good attention to the wiring of the DRVRMOTLRR. The limit switches are wired as follows:
Fig. 8; Schematic Rot. Limit Switches DRVRMOTLRR
Fig. 9; Numeric Rot. Limit Switches DRVRMOTLRR
If you want to rotate your pincer, both rotational units (Motor 1 and 2) must turn in the same
direction. To open or close your pincer, motor 1 must rotate and motor 2 holds it’s position.
CAUTION: The rotation limit switches are only electric and don’t function as as a
mechanical limit stop! Ferrovac rejects all liability in case of incorrect use or
adjustment.

Setup and Installation
3.3. Mounting
In delicate situations, the mounting procedure exposes the sample transporter and the motorization
to the risk of being damaged. Please follow the warning notes and the illustrated instructions.
CAUTION!
Always use powder-free examination gloves during mounting to avoid contamination.
Never expose the Sample Transporter to physical shocks (brittle magnets!!!).
Never bend the tube nor the shaft.
Never hit the knife edge.
3.4. Tube support
Especially sample transporters with longer travel ranges require special care to be taken so that the
operators do not accidentally bend the tube while the sample transporter is not in use. Also the
resulting leverage in case of high weight can bend the shaft or break the flange. The support is
simply mounted to the blue plate at the end of the motorization with two screws (Order Code
TSRMB)

3.5. Bakeout
The motorization is not bakeable! Follow the following steps to remove it:
1. Remove the two screws on the left and right side on the guide carriage.
2. Remove the two screws on the front and at the back of the motorization. Don’t carry out this
step alone! Work as a couple, one person holding the motorization while the other person
undoes the screws.
3. Lift the complete motorization unit carefully.

DRVRM Technical Reference Manual
14/14
May 23 REV B
All UHV sample transporters (including the RM40), without motorization, are bakeable up to 150°C.
Do not remove the magnetic coupling for the bakeout procedure.
In order to minimize formation of residual gas, it is helpful to move the coupling back and forth
during cooldown of the UHV system after bakeout.
4. Problem solving
4.1. Factory overhaul
The slide and ball bearings are the only parts of the sample transporter that wear out. Many bakeout
periods lead to slight deformation of the slide bearings. This could result into disturbances of the
motion smoothness and probably higher outgassing rates. We offer an full factory overhaul for inner
and outer bearings and readjustment of any style of pincer grip. For more information please contact
us directly.
4.2. Declaration of decontamination
In case of returning the sample transporter to us, it is necessary to complete a declaration of
contamination and send it to us. Please contact us for this.
4.3. Download
This manual can be downloaded from our website. It can be found in the specifications of each listed
sample transporter motorization.
CAUTION! Never remove the magnetic coupling for the bakeout procedure. Make
sure it’s temperature never exceeds 200°C!
