MICRO-EPSILON gapCONTROL 2711 Assembly Instructions

5. Laser Class
The gapCONTROL 2711 sensors operate with a semiconductor laser having a wavelength
of 658 nm (visible/red). The laser operation is indicated visually by the LED on the sensor.
Laser Class 2M
The gapCONTROL 2711 sensors with a maximum laser power up to 10 mW are classified
in Laser Class 2M (IIM). The following information labels are fitted to the sensor housing
(front and rear side).

If both information labels are hidden in the installed state, the user must ensure that
additional labels are fitted at the point of installation.
IEC 60825-1: 2008-05

Hazard to the eye via laser radiation! Consciously close your eyes
or turn away if the laser radiation impinges on the eye.
Lasers of Class 2M are not subject to notification and a laser protection officer is not
required. Mark the laser area recognizable and everlasting.
Laser Class 3B
The gapCONTROL 2711 sensors with a maximum laser power up to 20 mW are classified
in Laser Class 3B (IIIB).
Injury to the eye or the skin via laser radiation! Consciously close
your eyes or turn away if the laser radiation impinges on the eye or
the skin.
Class 3B (IIIB) laser sensors are notifiable and a laser protection officer is required either.
During operation the laser area has to be restricted and marked. The following information
label should be fitted to the sensor housing (front and rear side):

to switch off the laser, see
Chap. "Laser switching".
Beam attenuator
The beam attenuator prevents access to all
laser and collateral radiation. The figures show
the sensor with closed and open beam attenu-
ator. The beam attenuator must be open during
measurement.

The power supply is also possible using the FireWire connection cable, if the power sup-
ply needed is present in the PC with sufficient current intensity. When both voltages (1394
and power) are present, the higher voltage always takes over the supply of the sensor.
External laser switching
Series gapCONTROL 2711-x(002), gapCONTROL 2711-x(003), gapCONTROL 2711-
x(004) and gapCONTROL 2711-x(005) offer this function.

Sensors of Laser Class 3B (IIIB) need an external key switch to switch off the laser.
Use a serial key switch inside the control circuit to switch off the laser. You will find
details for the wiring in the instruction manual, Chap. 5.2.4.

The RS422 port can be used with either of the following configurations:
- RS422: Loading of programs and transmitting of measurement results (ASCII format).
- Synchronization/Triggering: Synchronization resp. triggering using switching signals.
Optional RS422 interface cable (SC2700-4,5RS422) from Micro-Epsilon, compatible to

the RS422 to USB converter. All outputs or inputs are designed symmetrically. Internal
terminating resistors 120 Ohm.

The gapCONTROL 2711 sensor can also be supplied with operating voltage from the PC
on the 1394 connection socket. If its capacity is not sufficient, an appropriate voltage must
be connected to the 24 VDC socket.
Use the recommended FireWire connection cable.
A power supply via free cores in the FireWire connection cable is possible if these wires
are connected in the PC (Pin 1 to +8 ... 30 VDC, typically 12 VDC; Pin 2 to ground on the
FireWire connector).
