Shutter Switch (Keyswitch models only) – The Shutter Switch is a mechanical shutter that closes the
laser aperture and also actuates independent micro-switches that interrupt power to the laser
section(s). The shutter should not be used to partially block the beam or to control output power.
Power LED – The PWR LED is a panel mounted LED that illuminates green when the Keyswitch is
turned to the ON position (or when an OEM laser is powered up) to indicate that power is applied
to internal circuitry.
Lase LED – The LASE LED is a panel mounted LED that illuminates red to indicate the lase mode of
operation. If a tickle signal is present, the red LED turns on after the five-second delay and becomes
brighter as the PWM Command duty cycle is increased.
Keyswitch (Keyswitch models only) – The panel-mounted Keyswitch is used to turn the laser on, off, and
to reset faults. The key cannot be removed when the Keyswitch is in the ON position. For OEM
lasers, a plug is installed in place of the Keyswitch and the keyswitch wires are shorted. The remote
keyswitch pins of the DB9 Connector then become the external power on/off/reset control means.
Fuse – The panel-mounted fuse(s) provides overcurrent protection for the internal circuitry of the laser.
The required fuse is a fast-blow type AGC/3AG rated at 32 V minimum with the following current
ratings: 48-1 – 10 A; 48-2 – 20 A; 48-5 – 20 A (2 required)
DB9 Connector – The DB9 Connector is a 9-pin, female subminiature-D connector that provides an
interconnection for message, fault shutdown, remote interlock, remote keyswitch, and interface
signals. Refer to DB9 connections in the “Getting Started” section for connection information.
Command (CTRL) Input – The CTRL connector is a BNC-style jack that accepts tickle and PWM
Command signal inputs. The output of the UC-2000 Controller (or FH Series marking head) is
attached to this connector. For pure CW operation, a steady +5 V signal can be applied through this
