It is also possible to match the MJB2 and MJB4 models (without muting
lamp and override command) with muting light curtains as they are fitted
with the required settings.

If connecting an MJB1 or MJB3 model to a JANUS J series safety barrier
(without Muting function), the following connections must be disregarded:
SW1 (pins 1,2,3,4), CJ5, CJ7 (pins 7,8) and CJ9.

For the JANUS, MI, ML, MT versions use of a muting lamp (internal or
external) (0.5 5W) is obligatory for correct functioning of the light
curtains.

Where the risk analysis of the application requires it, the light curtain
permits connection of an external lamp to signal active Muting (0.5 5W).
Perform a check of the operation of this lamp periodically verifying its
turning on during the Muting or Override phase.
