LDS1000 Controller for Laser Diode Sensors
5.3 Power Up
5.3.1
Power Up Messages
Link up the controller to the mains. Set the switch to “I” (IN).
Once turned on, the controller goes into its initialization phase and dis-
plays a welcome message.
Then, the display of values measured according to programming parame-
ters is displayed:
This presumes that the autocollimator is stationary in front of a mirror
which sends the correct beam into the measuring range (see paragraph:
“Alignment”).
In other cases, the controller displays the value of the limits of the measu-
ring range (the most frequent being -2000 µrad) instead of the value measu-
red on the given axis:
See paragraph: “Alignment”.
Other possible messages:
LASER ERROR: This message indicates a connection error in the optical
head or a laser diode emission fault.
This message indicates that the controller is connected to a computer on
which software is running, which has sent the command to freeze the dis-
play. Reset the software parameters to regain control.
This type of message indicates, for controllers equipped with analog
options, that the analog output mode is active. Press the MAIN key to
return to the main menu.
5.3.2
Alignment
To visualize an angular measurement, make sure that the return beam
penetrates the LDS-Vector autocollimator and that the return energy is
powerful enough.
The procedure for rapid set up is explained in the user’s manual supplied
with each instrument.
