WARNING
Commissioning requires a thorough check by qualified safety personnel!
Before you operate a system protected by the M4000
multiple light beam safety device for
the first time, make sure that the system is first checked and released by qualified safety
personnel. Please read the notes in chapter 2 “On safety” on page 10.
9.1 Display sequence during start-up
After the system is activated, sender and receiver go through a power-up cycle. The 7Eseg-
ment display indicates the device status during the power-up cycle.
The indications have the following meaning:
Display Meaning
, , , ,
, , ,
Testing the 7Esegment display. All segments are activated
sequentially.
Ca. 0.5 s. Is displayed only at the receiver and only in operation with
large scanning range.
, or Ca. 0.5 s. Non-coded operation or operation with code 1 or 2
, , or Receiver only: Sender–receiver alignment is not optimal (see
chapter 9.2.1 “Meaning of the 7Esegment display during alignment”
on page 90ff).
Other display Device error. See chapter 12 “Fault diagnosis” on page 105.
9.2 Alignment of the M4000
After the multiple light beam safety device has been mounted and connected, you must
align the sender and receiver precisely in relation to each other.
Alignment is performed by mechanically adjusting the M4000 components. During this
process the M4000 is in the alignment mode. You can then see when the optimal align-
ment is achieved on the 7Esegment display on the receiver.
The alignment mode is automatically activated when the multiple light beam safety device
is switched on if the light beams are not yet aligned or the light path is interrupted.
Alignment aids
You can conveniently and accurately align the devices using a laser alignment aid. An
alignment aid is recommended particularly when a M4000 system is used with deflector
mirrors (each mirror on the mirror columns must be adjusted).
The following alignment aids are available:
integrated laser alignment aid per beam (optional, only for M4000 Advanced)
On this subject read the description in chapter 9.2.4 “Alignment of the M4000 Ad-
vanced with integrated laser alignment aid (optional)” on page 95.
alignment aid AR60 + adapter for M4000 (see section 14.7 “Accessories” on page 139)
On this topic read the description in the operating instructions for the “Alignment aid
AR60”.
