Display

Possible Cause

Short circuit to 0V at OSSD connection 1

Overcurrent on OSSD connection 2

Short circuit to 24V at OSSD connection 2 Check the wiring for short circuit to 24V.

Short circuit to 0V at OSSD connection 2

Short circuit between OSSD connection 1

and 2

General OSSD wiring error

The SafeZone Mini device is receiving no

measured values within a range of at

least 90° (measuring range maximum

29.9 m (98.1 ft), it is not detecting any

obstacles such as building walls.

Device is faulted.

Temperature error. The operating

temperature of the SafeZone Mini device

has exceeded the permissible range.

Invalid configuration of the EDM.

Undervoltage of the supply voltage

There is a short circuit between the input

for the control switch for restart or reset

and another input or output.

Park/stand-by mode, the OSSDs of the

SafeZone Mini device are in the OFF state;

the laser is deactivated.

Optics cover calibration active.

Window for light output on the optics

cover contaminated

Optical saturation of the contamination

measurement (there may not be an

and

optics cover fitted)

Corrective Action

Check the wiring for short circuit to 0V.

• Check the switching element connected (contactor, relay). Replace, if necessary.

• Check the wiring for short circuit to 0V.

Check the wiring for short circuit to 0V.

Check the wiring and rectify the error.

Check the complete wiring of the OSSDs.

For the correct function of the safety laser scanner, always verify that measured values are received within a

range of 90°; this range can be moved as required within the scan range.

• Check whether an external light source, for example, headlight, infrared light sources, stroboscopic light, or

sun is affecting the SafeZone Mini device.

• If necessary, remount the device.

Check whether the SafeZone Mini device is operated as per the permissible ambient conditions.

Verify that the machine-side EDM is connected correctly.

Check the power supply or the connecting cables.

Check the wiring for cross-circuits.

No error. If the criteria for the park mode or the stand-by mode are withdrawn, readiness for operation is

reestablished.

If the display

does not go off:

Test the levels at the universal I/O and at the control inputs that switch to the monitoring case with park mode.

No error.

Clean the window for the light output on the optics cover.

Check whether an external light source, for example, headlight, infrared light source, stroboscopic light, or sun is

affecting the SafeZone Mini device.

Or:

• Fit the new optics cover.

• Then, perform optics cover calibration.

IMPORTANT If you have problems during troubleshooting, contact Rockwell Automation

support. Keep a copy of the results of the diagnostics at hand.

The SCD software is supplied with the devices. It allows you to narrow down

the problem if the error is non-specific or if you experience usage downtime

problems. Find detailed information in the online help for the SCD software.
