LASER Error Indicators
The LDC-3700C Series Laser Diode Current Source Controllers indicate general
LASER operational error conditions. Each error condition results in a controller
action as shown in the following table.
Table 2.1
Laser Error Indicators
Error Condition
Action
Interlock
Output off, INTERLOCK light flashes at 1 Hz
Open circuit
Output off, OPEN CIRCUIT light flashes at 1 Hz.
If this condition was caused by an excessively high
compliance voltage, the VOLTAGE LIMIT light will also
be turned on.
Output shorted
OUTPUT SHORTED light comes on. This indicator
becomes
lit whenever the LASER output is off.
Current limit
CURRENT LIMIT light flashes at 1 Hz
Voltage limit
VOLTAGE LIMIT light flashes at 1 Hz. This indicator warns
that the output is within 0.25 volts of Voltage Limit. If
voltage limit is reached, the LASER output will shut off.
Optical Output Power Limit
Output off, POWER LIMIT light flashes at 1 Hz
