IEC power in/out
The unit should be preset for the appropriate voltage for your coun-
try. Please contact
MOG
labs for instructions if you need to change
the power supply voltage.
The output IEC connector is a direct connection to the input power,
after the input mains filter. This outlet should be used only to power
a monitoring oscilloscope. It is provided to minimise ground-loop
noise problems.
Fan
The fan speed is temperature-controlled.
Interlock
The
DLC
will not power on the laser unless the pins on this connector
are shorted. A standard 2.1 mm
DC
plug is provided.
LASER
Connection to laser head. This connector provides diode current,
two piezo drives, temperature sense, and
TEC
current. A
DVI-D Dual
cable is provided.
WARNING:
The piezo drive signals can be lethal. The high-voltage
outputs, diode current and
TEC
current will be disabled if the cable
is disconnected, or if the main or head interlocks are open-circuit,
but these protection features should not be assumed.
T
gain
Temperature control feedback gain. Increase this if the response
time is too great or if the temperature error is large. Reduce this if
the temperature oscillates.
CHANNEL A, B
Monitor outputs; connect to oscilloscope, channels 1 and 2.
