Instruction Manual
Troubleshooting and Maintenance
5.2 Test Mode
If System will not align or go to a Green/Clear condition, the
emitter’s Test input may be open. If so, the receiver Reset
indicator will be Yellow, all Zone indicators Red, and the Status
LED Red; the 7-segment display will show a numerical value
equal to the total number of beams, minus one. (Multiple-digit
codes are displayed sequentially.) For example, if an array has
55 beams total, the display would indicate 54. The emitter’s
Status indicator will flash Green. See Section 4.4 and Figure 5-1.
(Exception:ona14-beamsystemonly,theZone1indicatorwill
be Green, and all others Red.)
5.1.2 Emitter Error Codes
Multiple-digit codes are sequential, followed by a pause.

Error Description Cause of Error and Appropriate Action
Emitter Error
This error can occur either due to
excessive electrical noise or due to an
internal failure.
•Resettheemitterbyeitherperformingaresetorcyclingpowertotheemitter(see
Section 4.3).
•If the error clears, perform the daily checkout procedure (Section 6.3) and if OK,
resume operation.
If the System fails the daily checkout procedure, replace the emitter.
• If the error continues, check the ground connection (see Section 2.3).
•If the sensor has a good earth ground connection, check for electrical noise (see
Section 5.3).
•If the error continues, replace the emitter.
Excessive Noise Error
This error can occur due to excessive
electrical noise.
•Resettheemitterbyeitherperformingaresetorcyclingpowertotheemitter(see
Section 4.3).
•If the error clears, perform the daily checkout procedure (Section 6.3) and if OK,
resume operation.
If the System fails the daily checkout procedure, replace the emitter.
•If the error continues, check the ground connection (see Section 2.3).
•If the sensor has a good earth ground connection, check for electrical noise (see
Section 5.3).
• If the error continues, replace the emitter.

Supply
Voltage
Other Conditions Appropriate
Action
10 to 30V dc Emitter should be in
Run mode with beam
scanning occurring.
If not, check the
+24V dc (pin 1,
brown) to verify
proper supply
voltage
Outside the
rated supply
voltage
specifications
—
Correct the supply
voltage and recheck
emitter operation.
10 to 30V dc Test1 is 10 to 30V dc,
but emitter is not in
Run mode with beam
scanning.
Replace the emitter.
Less than
3V dc
Emitter should be in Test
mode with no scanning
occurring.
If not in Test mode,
replace the emitter.
Figure 5-1. TEST mode status indicators
Opening a switch or relay contacts connected to the emitter Test
connections, or supplying a voltage of less than 3V dc to Test
only, simulates a Blocked condition, for testing purposes.
To verify proper operation, measure the voltage between emitter
Test (pin 8, violet) and dc COM (pin 6, blue) and refer to the
followingtable:
*The 7-segment display will sequentially show a numerical value equal to one
less than the total number of beams. For example, if an array has 55 beams total,
the display would indicate 54.
