Error Descriptions and Causes
Appropriate Action
EDM 1 Error
This error can occur when the EDM 1
input signal fails to respond within 250 ms
of the OSSDs changing stat\e (ON to
OFF).
Verify that the EDM wiring is correct and that the external devices meet the requirements
Machine Primary Control Elements and EDM Input
on page 40.
•
If the error continues, remove power to the guarded machine, disconnect the
OSSD loads, disconnect the EDM input signals, configure EDM for No Monitoring
Machine Primary Control Elements and EDM Input
on page 40), and conduct
the Initial Checkout procedure in
•
If the error clears, the problem is in the External Device contacts or wiring, or is a
response-time problem of the external devices. Verify that the EDM wiring is
correct and that the external devices meet the requirements described in
Primary Control Elements and EDM Input
on page 40.
•
If the error continues, check for noise on the EDM inputs (see
on page 80).
EDM 2 Error
The EDM 2 configuration is not valid.
•
Verify that the EDM wiring is correct and that the external devices meet the
requirements described in
Machine Primary Control Elements and EDM Input
page 40.
•
If the error continues, remove power to the guarded machine, disconnect the
OSSD loads, disconnect the EDM input signals, configure EDM for No Monitoring
(per
Machine Primary Control Elements and EDM Input
on page 40), and conduct
the Initial Checkout procedure (see
on page 32).
•
If the error clears, the problem is in the External Device contacts or wiring, or is a
response-time problem of the external devices. Verify that the EDM wiring is
correct and that the external devices meet the requirements described in
Primary Control Elements and EDM Input
on page 40.
•
If the error continues, check for noise on the EDM inputs (see
on page 80).
Fixed Blanking Error
This error occurs when beam(s) that have
been blanked (programmed to ignore a
fixed object) become clear when the
object is removed or moved.
•
Reposition the object and perform a key reset (or cycle power).
•
Re-program (teach) the fixed blanked object(s), see
Programming Timeout Error
This error occurs when the Fixed Blanking
programming mode (teach) exceeds the
ten-minute limit.
Re-program (teach) the fixed blanked object(s), see
Cascade Configuration Error
This error occurs when the configuration
sequence is incorrectly followed,
receiver(s) 2, 3 or 4 are configured, or
receiver 1 is moved to a different position
in the cascade.
•
The CSSI Input channel(s) are shorted together or to another source of power or
ground.
•
Configure ONLY the first receiver in the cascade (connected to the machine
interface). All other receivers must be set for 2-Ch. EDM (E2) and Trip Output (T),
see
Cascaded Sensor Configuration Settings
•
Re-configure the first receiver to adapt system to changes or replacement of other
receivers, see
Cascaded Sensor Configuration Settings
on page 70.
In a cascaded system, all receivers are connected together, and all emitters are connected
together.
Excessive Noise Error – Reset Interface
This error occurs due to excessive levels
of electrical noise.
•
on page 50.
•
If the error clears, perform a Daily Checkout procedure (per
on page 61) and if OK, 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 (
•
If the error clears, check for sources of electrical noise (see
on page 80).
•
If the error continues, replace the receiver.
Excessive Noise Error – EDM Interface
This error occurs due to excessive levels
of electrical noise.
Excessive Noise Error – Cascade Input
This error occurs due to excessive levels
of electrical noise.
