Description
The low-pressure safety switch PS 113 A is used as a pressure safety switch in
vacuum systems.
Intended Use
The low-pressure safety switch PS 113 A is used as a pressure safety switch in
vacuum systems. It is used e.g. to automatically interrupt the gas supply when
venting vacuum systems with a purge gas at a pressure of 3 mbar below atmos-
pheric pressure.
Unpacking and Checking
Unpack the low-pressure safety switch PS 113 A immediately after delivery, even if
it is to be put into operation at a later date.
Before doing so, examine the shipping container for any external damage. Then
completely remove the packaging materials.
The shipping container and packaging materials must be kept in the event of com-
plaints about damage.
In order to ensure that no damages have been caused during transport carefully
examine low-pressure safety switch PS 113 A visually.
If any damage is discovered, report it immediately to the forwarding agent and
insurer. If the damaged part has to be replaced, please get in touch with the orders
department.
General Information
GA09616_002_C0 – (2016-10) – Leybold 3
Design and Function
At a differential pressure of 6 mbar when pumping down or 3 mbar when venting
below atmospheric pressure, an elastic diaphragm actuates a changeover contact
which in turn may be used to directly switch any ancillary equipment. The electrical
connections are placed under a plastic cover.

3 Installation
3.1 Vacuum Connection
The PS 113 A is connected to the vacuum system via a DN 16 KF small flange.
The PS 113 A should preferably be mounted standing on its flange. Inclined
mounting is also permissible, including the horizontal position. Downward installa-
tion is not permissible because in such a case condensate may collect in the pres-
sure switch. This affects the measurements and may damage the pressure switch.
3.2 Electrical Connection
Fig. 2 Contact assignment of microswitch
The contact assignment is given in Fig. 2.
The PS 113 A is supplied with a connected 3 m long standard cable. The length of
this cable may be changed.
The electrical connection terminals and the strain relief are accessible after un-
screwing the cross head screws and folding out the cap.
The contacts at the PS 113 A are marked 1, 2 and 3 (see contact assignment
Fig. 2).
The supply line has to be fuse-protected with max. 100 mA by the end-user.
Adhere to the applicable regulations and take the necessary precautions for all
work you are going to do.
3.3 Start up
When leak detecting with a helium leak detector, spraying the pressure switch with
helium may result in a helium proof. This is in general not due to a leak of the
PS 113 A, but is permeation of helium through the EPDM diaphragm.
