WARNING:
Shut down the machinery before servicing
Servicing the Banner Engineering Corp. device or system while the hazardous machinery is oper-
ational could result in serious injury or death.
The machinery to which the Banner Engineering Corp. device or system is connected must not be
operating at any time during major service or maintenance. This might require lockout/tagout pro-
cedures (refer to OSHA1910.147, ANSI Z244-1, ISO 14118 or the applicable standard for control-
ling hazardous energy).
In addition to the standard error codes, the EZ-SCREEN SLS can display advanced diagnostic codes for factory trou-
bleshooting and repair functions. These codes are generally not intended for field troubleshooting by the EZ-SCREEN
SLS user.
These advanced codes have three digits (alternating “Axx”/“Bxx”, where “xx” are two alpha-numeric characters). To display
these codes:
Hold the Reset input high (+24 V dc), or
Hold the Invert Display button down for five seconds during a lockout condition.
If the advanced diagnostic codes are inadvertently displayed, hold the Invert Display button down for 5 seconds to return to
the standard error code display.

Error Descriptions and Causes Appropriate Action
Output Error
This error is caused by:
One or both outputs being short-
ed to a power supply (high or
low)
By shorting OSSD 1 to OSSD 2
By an overload (greater than
0.5A)
Disconnect the OSSD loads and reset 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.
Reset Input Error
This error occurs when the Reset switch is
closed (or the wiring is shorted to +24V)
during power-up.
Verify that the reset switch is in the open position.
Reset the receiver per "Emitter and Receiver Reset" on page 85 .
If the error remains, disconnect the reset wire at pin 8; cycle the power.
If the error clears, the problem is in the reset switch or in the wiring.
If the error persists, replace the receiver.
EDM Input Error
This error can occur for the following rea-
sons:
EDM wiring is incorrect
No connection to EDM connec-
tions
Both EDM inputs fail to respond
within 250 ms of each other
Excessive noise on EDM inputs
Loose QD connection(s)
Verify that the EDM wiring is correct for the EDM type configured (see " Machine Primary Con-
trol Elements (MPCE) and External Device Monitoring (EDM) Input" on page 44 ).
If the error continues, remove power to the guarded machine, disconnect the OSSD
loads, disconnect the EDM input signals, configure EDM for No Monitoring (see " Ma-
chine Primary Control Elements (MPCE) and External Device Monitoring (EDM) In-
put" on page 44 ), and conduct the Initial Checkout procedure in "Initial Checkout
Procedure" on page 35 .
If the error clears, the problem is in the external device contacts or wiring, or is a re-
sponse-time problem of the external devices. Verify that the EDM wiring is correct
and that the external devices meet the requirements described in "Machine Primary
Control Elements (MPCE) and External Device Monitoring (EDM) Input" on page 44 .
If the error continues, check for noise on the EDM inputs (see "Electrical and Optical
Noise " on page 89 ). If the error persists, replace the receiver.
