Pump Electrical Controller - Agilent Technologies TriScroll 800 Installation And Operation Manual

Pump Electrical Controller

The pump is powered by an inverter that converts single
phase line power into 3-phase power that drives an induction
motor at a user selectable frequency.
Several operational variables are modifiable through the J2
serial port when using Agilent T-Plus software. A number of
additional system variables are also viewable.
Pump operation is interlocked through the P1 connector. Pins
4 and 5, and Pins 8 and 9, must be connected together to
enable operation. A prewired connector is supplied with the
pump and should be plugged into P1. The maximum power
output of the inverter is 950 Watts. At pump inlet pressures
above approximately 20 Torr, the pump will be power limited
and the output frequency will be reduced. This mode is
known as autotuning.
At pump start, the drive frequency is ramped up over several
seconds. This provides for smooth starting and eliminates
large in-rush currents.

Remote speed setting allows you to control rotational speed
using a 0-10 V analog input:
V > 9 V: Driving frequency will be the full speed (fac-
in
tory set @62 Hz)
V <1 V: Driving frequency will be the minimum speed
in
(35 Hz)
NOTE Pump operation is interlock dependent.
The provided mating connector must be
plugged into P1 to start the pump.
