If the muting light is not present or faulty on your Reer Security Sensors, verify that the MUTING lamp is present and working efficiently.

What to do if muting light is not present or fault in Reer JANUS?
If the muting light is not present or faulty on your Reer Security Sensors, verify that the MUTING lamp is present and working efficiently.
What to do if Reer Security Sensors detect interfering emitter?
If your Reer Security Sensors detect an interfering emitter, try these steps: * Switch the positions of the emitter and receiver. * Move the interfering emitter so it doesn't illuminate the receiver. * Shield the beams from the interfering emitter using opaque protections.
What to do if there is an overload of the OSSD outputs in Reer JANUS?
If the OSSD outputs of your Reer Security Sensors are overloaded, carefully check the connection of terminals 2 and 3 on the connector. If necessary, adjust the load, reducing the current required to a maximum of 500 mA (2.2 ?F).
What to do if OSSD outputs incorrectly connected to +24VDC in Reer JANUS?
If the OSSD outputs of your Reer Security Sensors are incorrectly connected to +24VDC, carefully check the connection of terminals 2 and 3 (OSSD) on the connector. Ensure the load is positioned between the MUTING function (OSSD) and 0 Vdc.
What to do if there are unstable muting sensors signals in Reer JANUS?
If your Reer Security Sensors have unstable muting sensor signals, check the positioning of the muting sensors and verify the number of sensors connected, as well as the selected configuration.
What to do if there is a short-circuit between the OSSD outputs in Reer JANUS Security Sensors?
If there is a short-circuit between the OSSD outputs in your Reer Security Sensors, carefully check the connection of terminals 2 and 3.
What to do if there is an incorrect "SYSTEM STATUS" or overload signal connection in Reer Security Sensors?
If you encounter an incorrect 'SYSTEM STATUS' or overload signal connection with your Reer Security Sensors, check the connection of terminal 4.
What to do if there is an incorrect initial OVERRIDE configuration in Reer JANUS Security Sensors?
If you have an incorrect initial OVERRIDE configuration for your Reer Security Sensors, check the connections of terminals 16 and 17.
What to do if there is an internal error on the OSSD outputs (or incorrect connection of these) in Reer JANUS?
If you are experiencing an internal error on the OSSD outputs (or incorrect connection of these) with your Reer Security Sensors, carefully check the connection of terminals 2 and 3 (OSSD) on the connector. These terminals could be connected directly to + 24 Vdc or 0 Vdc. Otherwise, send the equipment for repair to the REER laboratories.
What to do if external contact enabling/disabling signal missing or contactors feedback missing in Reer Security Sensors?
If the external contact enabling/disabling signal is missing or contactors feedback is missing in your Reer Security Sensors, check the connections of terminals 11 and 18.
