connected to the green (GN) / red (RD) wire. If the EDM function is not
required for a particular application it is necessary to link the green (GN) wire
to the green (GN) / red (RD) wire. If the link is not fitted the safety system will
trip and it will not be possible to reset the light curtain.
Mute inputs M1 (F6) and M2 (F7) -
Mute inputs M1 (mute 1) yellow (YE) wire
and M2 (mute 2) white (WH) wire are for connecting external muting signals to
the 5K8 safety light curtain. The input signals should come from separate
sources, so that a single fault cannot cause a failure of the protective function.
When using the two external mutes the two mute signals are monitored via the
two second mute disparity timer.
Mute output (F8)
– The customer may need an additional mute lamp
indication on the machine as a visual warning for the operator. Connection of
a mute indicator lamp can be made by the wires in the B user cable. Connect
the yellow (YE) / blue (BU) wire to one side of the mute lamp and the other
side of the mute lamp is connected to +24V DC. Maximum switching current
rating is 500mA.
Mute lamp output (F9)
– This lamp is integrated within the horizontal muting
arm of the light curtain. The lamp acts as a visual warning indicator and will be
illuminated during a mute condition, i.e. pallet transfer.
Mute enable input (F10)
– It is a control requirement for the 5K8 series that an
additional 3
rd
mute input is provided via the conveyor run signal so as to maintain a
high level of safety integrity. This signal acts as a permissive signal to the cross
beam mutes and/or external mute input signals.
Connection of the 3rd mute input is via the red (RD) / blue (BU) wire to a normally –
open (N/O) ‘volt free’ contact to 0V DC. Contact closed when conveyor running.
Guard Override (F11)
– providing the light curtain is in a tripped condition and
the curtain is blocked by a loaded pallet then turning and holding the activate
switch (spring return) to ON will automatically turn-on the safety outputs (F1),
for a maximum period of 3 minutes. As soon as the loaded pallet clears the
light curtain the safety system will automatically reactivate to a ‘fully guarded’
condition and the spring return switch can now be released.
The Activate and Guard Override inputs are available from the user (B) cable.
The yellow (YE) / red (RD) is connected to a normally open switch contact and
the other side of the switch is connected to 0V DC.
Note:
These are for external mute inputs, e.g. inductive loops. When using
a self-muting 5K8 system e.g. inverted ‘T’ shape they are not available.
