MOST switch

The MOST - switch - switch is part of the PCM2. It keeps the electrical MOST closed if no other MOST control unit is optically connected to the MOST. The MOST switch is opened when a light signal is received from the connected MOST control units.

The following settings can be coded:

NOTE:
  • When the PCM2 is replaced, the coding must be performed according to the MOST control units connected.
  • When the Switch closed parameter is set, the switch remains closed even in existing MOST control units. Communication is then not possible.
