redPOWER QUBE Cased Fiber Laser User Manual
There are two modes for this function:
Absolute Mode: A signal level between 0V and 10V will linearly control the demand level of the
active pulse shape between 0% and 100% of the overall demand level.
Relative Mode: A signal level between 0V and 10V will linearly control the demand level of the
active pulse shape between 0% and 100% of the set demand level for that pulse shape.
7.6.5.8 Analogue Output
The output on Pin 10 can be used to remotely monitor the output power. This signal is
calibrated linearly from 0V to 10V, to read 10V for the rated output power of the QUBE Fiber
Laser.
The Machine Interface needs to have an external power supply connected for this function to
operate.
This signal is either the CW power when in CW mode or a time averaged value when in
modulated mode. It is the same value as displayed on the power meter panel of FiberView.
7.6.5.9 Diagnostic Outputs
Diagnostic outputs are grouped into the following:
Alarms, which stop operation.
Warnings, which indicate a problem but allow continued operation.
The presence of an alarm or warning is indicated by the transition of the ‘Alarm Status’ or
‘Warning Status’ output from false to true.
Alarm status will remain present until the alarm has been manually reset.
Warning status will remain present until the condition causing the warning has cleared. This
may not require manual intervention.
The actual alarm or warning codes can be read remotely, if required, using the Serial
Interface.
7.6.6 PL81 – Process Cabinet door interlock switches and PL82 –
Power Supply Remote Control
The QUBE Fiber Laser provides an ‘E-shutter’ safety function which puts the QUBE Fiber
Laser into a safe state if the process cabinet door is open at the same time as a voltage is
present at the pump diode PSU outputs. The E-Shutter is a dual channel circuit, using two
different types of CLPD, programmed independently using different software tools, that
conforms to EN ISO 13849-1:2015, (Safety of machinery. Safety-related parts of control
systems. General principles for design) category 4, performance level d (PL d).
The E-shutter monitors two process cabinet door interlock switches on PL81 and the actual
pump diode PSU outputs during normal operation and it also checks the process cabinet door
interlock switches and the pump diode PSU output monitoring circuits for faults.
The E-Shutter will shut the laser down via the emergency stop safety function if the door is
opened while the PSUs are enabled.
