3.3 Operating Features
The Banner EZ-SCREEN LS Basic Safety Light Curtain models described in this manual feature several functions
(depending on model).
3.3.1 Trip Output
The System is configured for Trip Output which allows the System to enter Run mode automatically. Other measures must
be taken to prevent a pass-through hazard; see
Reducing or Eliminating Pass-Through Hazards
on page 24 and the
warning below for more information.
The OSSD outputs turn ON after power is applied, and the receiver passes its internal self-test/synchronization and
recognizes that all beams are clear. The Trip Output also automatically resets after all beams are cleared.
WARNING:
•
Use of automatic (trip) or manual (latch) start/restart
•
Failure to follow these instructions could result in a serious injury or death.
•
Applying power to the Banner Engineering device, clearing the defined area, or resetting a latch
condition must not initiate dangerous machine motion. Design the machine control circuitry so that
one or more initiation devices must be engaged to start the machine (a conscious act), in addition
to the Banner Engineering device going into Run mode.
3.3.2 External Device Monitoring (EDM)
The External Device Monitoring (EDM) feature allows the EZ-SCREEN LS Basic to monitor the status of external devices,
such as MPCEs. The choices are 1-channel monitoring or no monitoring. EDM is used when the EZ-SCREEN LS Basic
OSSD outputs directly control the MPCEs or other external devices.
This feature is only available when an 8-conductor interface is used.
3.3.3 Fault Output
The current sourcing (PNP) solid-state output (70 mA maximum) is used for control functions that are not safety related; a
typical use is to signal a lockout (fault) to a programmable logic controller (PLC). Available on both the receiver and emitter,
the output provides a fault signal (lockout = On). Interrupting (blocking) the sensing field is not considered a lockout, so the
Fault Output does not change state.
This feature is available only when an 8-conductor interface is used.
