Error Description Appropriate Action
Test Input Error
This error can occur if excessive
noise is present on the test input . • Reset the emitter by disconnecting and reapplying power to the emitter (see
Section 4.2).
• If the error clears, perform a Daily Checkout procedure (Section 6.4) and if OK,
resume operation . If the system fails the Daily Checkout procedure, replace the
emitter .
• If the error continues, check the ground connection (terminal 1).
• If the sensor has a good earth ground connection to terminal 1, check for
noise on the test input wiring (see Sections 5.2 and 5.3).
Emitter Error
This error can occur either due to
excessive electrical noise or due to
an internal failure . • Reset the emitter by disconnecting and reapplying power to the emitter (see
Section 4.2).
• If the error clears, perform a Daily Checkout procedure (Section 6.4) and if OK,
resume operation . If the system fails the Daily Checkout procedure, replace the
emitter .
• If the error continues, check the ground connection (terminal 1).
• If the sensor has a good earth ground connection to terminal 1, check for
electrical noise (see Section 5.2).
• If the error continues, replace the emitter .
Excessive Noise Error
This error can occur due to
excessive electrical noise. • Reset the emitter by disconnecting and reapplying power to the emitter (see
Section 4.2).
• If the error clears, perform a Daily Checkout procedure (Section 6.4) and if OK,
resume operation . If the system fails the Daily Checkout procedure, replace the
emitter .
• If the error continues, check the ground connection (terminal 1).
• If the sensor has a good earth ground connection to terminal 1, check for
electrical noise (see Section 5.2).
• If the error continues, replace the emitter .
