Vent Accessories; Tv 1001 Sem Controller Compatible; Standard Rack Controller Compatible - Agilent Technologies Varian TV 1001SEM Bedienungshandbuch

The water temperature must be between +10°C
and +20°C, with an inlet pressure between 3 and 5
bar. This allows a flow of about 200 l/h.
NOTE
The water electrical conductance must be
μ
s/cm. When the conductance is higher, in closed
water circuit, the use of up to 20% of Ethyl-Glycole
is suggested.

VENT ACCESSORIES

The vent valve and vent device allow to avoid un-
desired venting of the pump during temporary
power failure and enables an automatic vent op-
eration.

TV 1001 SEM Controller Compatible

Vent Valve mod. 969-9834
This vent valve waits before opening a minimum
time of about 5 sec. This time can be increased up
to about 220 min. by means of a setting of the
T-Plus software (optional).
To install the vent valve, unscrew the threaded
plug (see figure below).
Then screw the vent valve into the pump and
tighten it using a 16 mm hexagonal spanner with a
torque of 2.5 Nm.

Do not overtighten the valve as this may damage
the thread on the pump.
Then connect the cable from the valve to the suit-
able connector on the controller (see the preced-
ing paragraph "INTERCONNECTIONS").

Standard Rack Controller Compatible

Vent Valve mod. 969-9843
This vent valve has a fixed delay time of about 5
sec. This value can be used only with rack control-
ler.
To install the vent valve execute the same steps
as the vent valve model 969-9834 (see the above
paragraph).
