WARNING:
•
Shut down the machinery before servicing
•
Servicing the Banner Engineering device or system while the hazardous machinery is operational
could result in serious injury or death.
•
The machinery to which the Banner Engineering device or system is connected must not be
operating at any time during major service or maintenance. This might require lockout/tagout
procedures (refer to OSHA1910.147, ANSI Z244-1, ISO 14118 or the applicable standard for
controlling hazardous energy).

Error Description
Appropriate Action
Output Error
Error is caused by:
•
one or both outputs being
shorted to a power supply
(high or low)
•
by shorting OSSD 1 to OSSD
2
•
by an overload (greater than
0.5 A)
•
Disconnect the OSSD loads and cycle power to the receiver.
•
If the error clears, the problem is in the OSSD load(s) or in the load wiring.
•
If the error continues with no load connected, replace the receiver.
Receiver Error
This error can occur due to either
excessive electrical noise or an internal
failure.
•
on page 58.
•
If the error clears, perform a Daily Checkout procedure (per EZ-SCREEN
Checkout Procedures: Shift and Daily Checkout Procedure; Daily Checkout
Card) and if the System checks out, resume operation. If the System fails the
Daily Checkout procedure, replace the receiver.
•
If the error continues, check the ground connection (pin 7).
•
If the sensor has a good earth ground connection to pin 7, perform the Initial
Checkout procedure (per
on page 37).
•
If the error clears, check the external connections and configuration settings.
•
If the error continues, replace the receiver.
Optical Noise Error
This error can occur due to excessive
optical noise
•
Verify alignment of emitter and receiver as described in
Installation of Multiple Systems
on page 30, and
Sensor Mounting and Mechanical Alignment
on page 34.
•
Check for crosstalk between adjacent systems and correct installation and
alignment as needed
•
Cycle power and perform

This error can be caused by excessive
electrical noise.

•
If the error clears, perform the daily checkout procedure (per EZ-SCREEN
Checkout Procedures: Shift and Daily Checkout Procedure; Daily Checkout
Card) and if the System checks out, resume operation. If the System fails the
Daily Checkout procedure, replace the receiver.
•
If the error continues, check the ground connection (pin 7).
•
If the sensor has a good earth ground connection to pin 7, perform the Initial
Checkout procedure (
on page 40).
•
If the error clears, check for sources of electrical noise (see
on page 60).
•
If the error continues, replace the receiver.
