Important: * The SL-C Series muting function is designed so that it cannot be active while FSD is in the
OFF-state. As a result, the SL-C Series does not go to the muting state when any beam axes
are being blocked or when the restart interlock is enabled, even if the signals from the 2
muting devices turn ON.
* Bank switching input requires 2 (double) channels of signal input. As a result, if one of the
channels is ON while the other is OFF for 200 ms or more, the light curtain (SL-C Series)
goes to the lockout condition.
* At least 1 of the bank switching inputs must be ON prior to the signal input from the second
muting device (in the example above, the input signal from sensor A2). Therefore, in order to
switch among the 3 banks, you must turn the bank switching input ON when the SL-R12EX
detects no signals from the muting devices, or when it only detects the signal from the first
muting device (in the example above, the input signal from sensor A1).
* If additional bank switching input is made while a muted beam axis is blocked, the FSD turns
to OFF- state.
* When the SL-R11 receives an E-STOP input signal, the FSD always turns OFF-state and
the light curtain (SL-C Series) automatically goes to the restart interlock state, even if it has
been in the muting state. When the E-STOP input signal is canceled and the restart input
turns ON, the light curtain (SL-C Series) returns to normal operation, rather than resuming
the set muting state. As a result, in order to return the light curtain (SL-C Series) to the
muting state again, you must temporarily cancel the input signals from the muting devices
that have been activated and resend the input signals from them to the SL-R12EX.
* If there is no bank switching input to the SL-R12EX while the signals from the muting devices
are ON, the programmable muting bank function does not get active and the light curtain
(SL-C Series) keeps normal operation. However, the muting lamp turns ON if there is signal
input from the muting devices.
* The SL-C Series cannot go to the muting state after 1 muting device turns OFF, even if both
devices then turn back ON again. Both muting devices must turn OFF to get muting function
active again.
