Light Curtain Multi-Function Control Module User Manual
Original instructions
Muting of the Micro 400 light curtain is achieved only when muting sensor S1 and S2 are activated within the specified time t(sens). For a successful
muting sequence all four sensors must be simultaneously activated for a certain time period. The muting condition will stop when either sensor S3 or S4
is deactivated, or the maximal muting time t(mute) is exceeded (muting time out). Since this muting mode is bidirectional, the muting sensor sequence
will also function in reverse (i.e. S4 =>S1).
The following parameters can be configured in the configuration window ( Figure 62) for “four sensor T-type” muting.
Table 2 (* = a setting smaller or close to the total response time may influence the stability of the muting system)
A time t(sense) of 4 s is recommended in IEC 62046
Figure 62: Configuration window for “four sensor T-type” muting
Figure 62 also shows the corresponding wiring diagram of the MSR42 control unit configured with the “4 sensor T-type” muting mode.
5.6.12. Setup: two sensor L-type
Figure 63 shows a schematic arrangement for a two sensor, parallel beam, unidirectional muting application: “two sensor L-type.” Either the Micro 400
or a GuardShield safety light curtain may be muted in this manner.
