Pumps with the optional CAS equipment with a 12-lead auxiliary cable are mounted with the following
possible options:
• Leakage sensor in the oil housing (CLS)
• Analogue temperature sensor (Pt100) for support bearing temperature monitoring. (Requires separate
Pt100 relay.)
Pumps with the optional CAS equipment 24-lead auxiliary cable have the same options as for the 12-lead
cable, and two additional analogue temperature sensors (Pt100) for stator winding temperature in 3 phases.
(Requires addtional Pt100 relays.)
The CAS system has been replaced by the MAS system. CAS is no longer available as a spare part, but if
necessary CAS may be replaced by the MAS 711 together with the MRM-01 relay. For more information
see CAS or MAS 711 + MRM-01 sensor connections (page 55).
