Selecting the pump model, the recommended settings are preloaded (instructions to
change these values are reported at point 4).
please note that these settings are for pumps without jackets.
CABLE
is an automatic recognition of the cable length (if the cable supports the feature). It can not
be changed by the user. In case of very long cables this value is used for automatic loss
compensation (see Vcable at point 4).
Select the preferred heating mode.
The heating mode can be chosen between
ACTIVATION
mode and
CONDITIONING
mode.
The
ACTIVATION
mode provides the power required to heat the getter material in order to
activate it.
The
CONDITIONING
mode provides the power required only to recondition the getter
material. The conditioning mode might be helpful to pre-condition the pump during the
baking process.
The selected mode is highlighted by turning the button to red background. If some working
parameters are changed, the red highlighting disappears (see point 4).
On the right half of the screen, the working parameters are shown.
The default values can be modified: touch the parameter value (its background turns to
yellow) and use the + and - buttons (4b) to increase or decrease the value.
When Vmax, Imax, Pmax and/or T are changed, an asterisk is marked beside the pump
name and the Activation and Conditioning buttons are no longer highlighted.
t_rise and t_hold can be changed for each output; however they do not belong to the pump
specific working parameters.
The parameters are explained in the following:
t_rise
is the time in minutes to ramp up the power from 0 to Pmax; 15 to 30 minutes are
usually recommended if starting from room temperature, default is 15 minutes.
t_hold
is the time in minutes (starting after t_rise) during which power is held at the maximum
value; after t_hold the output is turned off automatically. Setting t_hold = 0 (that is
), which is
also the default value, the output is not turned off automatically but only with the stop button;
60 minutes or more are recommended. 60 minutes are enough for activation if working at the
maximum recommended temperature Tmax, more time is better and is necessary if the
system must stay at a lower temperature.
