3.3 Operating Features
The Banner EZ-SCREEN LS Basic 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
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 Start/Restart (Trip Output)
Application of power to the Banner device, the clearing of the sensing field, or the reset of an error
condition must not initiate dangerous machine motion. Machine control circuitry must be designed so
that one or more initiation devices must be engaged to start the machine (a conscious act), in addition to
the Banner device entering Run mode. Failure to follow these instructions could result in a serious injury
or death.
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 with the 8-conductor models.
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 with 8-conductor models.
3.3.4 Scan Code Configuration
Use the scan code to allow operation of multiple pairs of emitters and receivers in close proximity without the effects of
cross-talk. The emitter and receiver may be configured to use one of two scan codes (1 or 2); a receiver recognizes light
only from an emitter with the same scan code. Set the scan code using the wiring on each sensor (see
page 42). The scan code is configured at power-up and remains set until the input is changed and power is cycled. Both
the emitter and its corresponding receiver must have the same setting.
This feature is only available with the 8-conductor models.
3.3.5 Wiring Options
The Machine Interface connection has several options, including:
•
A 300 mm (1 ft) pigtail cable with an 8-pin M12/Euro-style male quick disconnect (QD) (DELSE-81D)
•
A 300 mm (1 ft) pigtail cable with a 5-pin M12/Euro-style male quick disconnect (QD) (DELSE-51D)
•
The Removable Disconnect (RD) that can mate with an 8-wire flying lead RD cordset (RDLS-8..D)
