Notes on operating the controller
Valves and/or vacuum pumps are necessary to operate the control-
ler.
Note: Texts written in Courier font mirror the display of the
controller.

Inside a vacuum system where evaporation
occurs, e.g., a rotary evaporator, the vacu-
um is not uniform. For example, a condens-
er can act as a pump, or the vacuum in the
connecting tubing can be higher or lower
than in the application itself. This affects the
measurement results as well as the control
levels.
Therefore, carefully choose the position where to con-
nect an external (optional) gauge head. Position an
optional external gauge head and its vacuum line in
such a way that condensate cannot flow towards the
pressure transducer. Condensate and deposits will
affect the measurement results. Clean the pressure
transducer, if necessary. See section ”Cleaning the
pressure transducer”, pg. 61.

Maximum permissible pressure: 21.8 psi (1.5 bar) ab-
solute.

Attention: At pressures above approximately 810 Torr
(1080 mbar) the pressure reading becomes incorrect
due to saturation of the pressure transducer. The dis-
play will flash. Release pressure immediately! Risk of
bursting!
