CONNECTING YOUR SYSTEM - BACK OF UNIT
TURNING ON YOUR SYSTEM
1.
Once the stage is mounted, connect stage to the controller ensuring that the connector screws are tightened to the controller
lock posts. The
stage must be mounted to a flat surface before being powered.
On power-up the controller will always
move
the stage across its range to carry out autocalibration. It is important to ensure that
there is sufficient clearance
between the lens, sample and illumination to allow this to take place.
If the temperature or load changes significantly the
stage can clip at one end of the travel. Should this happen restart your system to allow auto-calibration
; this rebalances the
stage so that the closed loop range is cent
e
red within the open loop range.
2.
Connect Power to
the
controller
and/or USB as required.
3.
Switch ON controller using switch on rear panel. After approx. 30 seconds, the relevant stage channel should show two green
lights (C
LOSED
and IN-POS). This indicates the stage is operating in the CLOSED loop mode and IN-POS LED indicates stage
has
reached position within a
pre-defined band.
4.
The analogue input and POS MON output is 0V to +10V giving a scale factor of 40µ
m
/volt
for the SP400 and 60µ/volt for the
SP600
. The
analogue input is enabled by
default.
5.
The system has 8 memory positions for PID settling (
accessible via the USB interface
). The system has been shipped with
two
optimized settings . The default setting has been optimized for loads from
150g to 500g
for use with an incubator, it is possible to
switch to a fast
setting for loads up to 350g.
Do not use the fast setting with an incubator or load
s
over 350g as damage may
occur.
To c
hang
e
to other settings
it
is necessary to connect to a computer,
described
in
the
software
section
below.
Remove input commands. If still vibrating please contact Prior
