Trouble Shooting
When the LED “Status Output” and “Status Error” are lit, the muting system is operating.
A simple functionality test can be performed interrupting each sensor for its own. Supposing that power is on, light curtain, muting
sensors and the muting lamp are connected. The function of each sensor can be checked with the sensor LED indicator.
When considering correct operation of the light curtain and muting sensors, the muting lamp will flash when interrupting one muting
sensor for a few seconds.
Check for the muting sequence according to Figure 3: Time for two sensor T-type.
Error Indications
Error in Sequence
If an error in the muting sequence has occurred, the muting lamp will blink (ca. 1 Hz), indicating that the muting condition will not be
initiated, or has been discontinued.
Make sure, that the muting sensor and the safety light curtain are uninterrupted. Check alignment of the safety light curtain and muting
sensors. Eventually the muting sensors and safety light curtain have to be cleaned.
Lockout
A non-illuminated LED “error status” indicates a lockout as described in the Software and Optical Interface section on page 14.
The reason for the lockout can be analyzed with the optical interface 445L-AF6150 and the safety software (see page 14).
Application Restrictions
The application is not intended for the following usage:
• In an explosive environment (EX),
• In radioactive areas or
• Outside of a temperature range of 0 … 55°C.
• Operating range < 2.5 m
(depending on muting sensors and light curtain)
For further restrictions, see technical specification of the safety light curtain and MSR42 Safety Controller.
