Important Note: Because AC input connections and requirements vary from country to country,
customers must provide the appropriately sized AC power cable or wiring.
Control connections
Complete all control connections to OEM v30 lasers through the Interface A (DB-9) or Interface B
(RJ45) connectors on the v30’s rear panel. The interface connector receives tickle pulse and PWM
Command signals and serves as the connection point for auxiliary signals between the laser and any
parts handling, automation, or monitoring equipment. See the Interface connections section in the
Technical Reference chapter for details.
Important Note: The OEM v30 control board does not incorporate a built-in tickle generator;
therefore, an externally generated 5 kHz, 1
μ
s tickle pulse must be applied between PWM
Command signals to achieve optimum laser performance. See Controlling laser power in the
Technical Reference chapter for tickle signal descriptions.
Use the Interface A (DB-9) connector for new or upgraded installations. Although both interface
connectors provide the same functionality, the DB-9 connector contains an additional output, Lase
Indicator, to indicate the OEM v30 is actively lasing. Use the Interface B (RJ45) connector only when
integrating a v30 into laser systems previously configured for an RJ45 interface.
Caution: Possible Equipment Damage
Do not reverse polarity when connecting DC power cables to your DC power source. Reversed DC
polarity will damage the laser’s internal RF power supply. Carefully follow the directions below to
ensure that DC cable leads are properly connected to the correct DC output terminals.
Warning: Serious Personal Injury
The use of the Quick Start Plug bypasses the laser’s safety interlock function; potentially exposing
personnel in the area to invisible infrared CO
2
laser radiation.
Because this plug jumpers the Laser Enable input signal, the laser will fire immediately on application
of a PWM Command signal. Your integrated control system should provide an interlock signal directly
to the Interface A (or Interface B) connector only after safe operating conditions are established.
The Quick Start Plug is intended only for initial testing and troubleshooting by qualified personnel. In
normal operation, the laser’s Laser Enable input should be connected to the machine’s safety
interlock circuitry.
