Devices with control input (for PY X-M-xx)
This option allows the beacon to be activated via control voltage.
The maximum current consumption of the control input is max. 1W.
Cable gland entries
To guarantee the specified protection type, cable grommets with a protection type of IP 66 are to be installed at the openings
provided for this purpose. The supplied diaphragm nipple can be replaced with a cable gland or with an M12 plug connection
with a flange measurement of M20.
Maintenance, Service and Ordering Spare Parts
The device does not require any special maintenance. External cleaning should be done with a mild soap solution without the
use of solvents. The device may only be operated in the undamaged state within the specified rating.
Conversions, alterations, improper and inadmissible use as well as the non-observance of the notes in these operating
instructions shall render the warranty null and void. Components may be replaced only by original spare parts. As a matter of
principle, repairs are to be carried out in the manufacturing works.
