TECHNICAL INFORMATION
SUBLIMATION CONTROLLER OUTLINE
The outline dimensions for the Sublimation Controller
base unit are shown in the following figure.
PUMP CONNECTION
The pump is connected to the controller rear panel
via “LOAD” connector (cable to be separately
ordered).
,
WARNING!
When installing the high power cable:
−
Turn the power off.
−
Plug the cable on the pump side and secure it
with the ring nut.
−
Plug the cable on the controller side and secure
it with the ring nut.
When removing the cable make sure that the power
is off.
REMOTE I/O CONNECTION
An external analogue unit can be connected to the
I/O connector to set some sublimation parameters
and receive feedback from the field.
The pin layout is shown in the following figure.

The correspondence between pin and signal is:
Pin 1 Input signal. Voltage range 0 to 10 Vdc. Used
for setting sublimation current value between 30
A (corresponding to 6 Vdc) and 50 A
(corresponding to 10 Vdc).
Pin 2 Input signal. Voltage range 0 to 5 Vdc. Used
for setting pressure threshold value: minimum
value 1*10
-10
mbar (corresponding to 0 Vdc),
maximum value 1*10
-4
mbar (corresponding to
5 Vdc).
Pin 3 Interlock. This pin must be shorted to one of
the common pins (number 4 or 6 to 9) (the
jumper is furnished with the controller).
Pin 4 Common.
Pin 5 Output signal. Voltage range 0 to 10 Vdc.
Used to feedback the sublimation current value
applied during sublimation (0 Vdc = 0 A, 10 Vdc
= 50 A).
Pin 6 to 9. Common.
NOTE
Without the interlock connection the controller
cannot operate.
If the controller is not connected with a remote unit
the tap furnished with the controller must be used.
If the controller is connected with a remote unit the
interlock must be correctly connected as described.
