Control unit AD
Control unit AD is used for two-line central lubrication systems. Control unit of AD2 series is used for lubrication pumps Z2, and control unit of AD3 series is used for lubrication pumps Z3. Control unit ensures star of lubrication pump in pre-set selected regime. Timer is equipped with pump operation signalling, signalling of faults and lubricant level in reservoir of the lubrication pump. Timer can be applied to any circuits, regardless of its own lubrication circuit construction and amount of lubricated points. The circuits can be fitted with terminal pressure switches (up to 3 pieces in standard), and two-line distributor operation signalling (up to 5 pieces is standard). The timer can be equipped with external light and audible fault signalling and connector for connecting into control (computer) system of the technological equipment.
