4.25 Interfacing to OEM equipment.
Telemark has experience of a wide number of differing schematics and pin designations used
by OEM’s around the World. We can provide either pre-wired connections or direct TVP to
vacuum system adapters upon request.
Leybold interface
One of the most common vacuum control systems encountered is based upon the Leybold /
Balzers / Unaxis type of interface.
The standard Leybold interface places 24VAC from indicate common 24VAC relays are
therefore required to isolate operates. Telemark supplies at nominal cost a directly mating
adapter for this type of interface.
New systems such as the SYRUS
TM
manufactured by Leybold Optic gmbH and its affiliates have
a different interface configuration.
Interface for SYRUS machine only.
