DETAILED DESCRIPTION

LVMP30A..

General characteristic

The LVMP30... priority change relays manage the alternation between 3 or 4 motors, with the purpose of making homogeneous operating time and wear. They are typically used in pumping systems where there may be 3 or 4 pumps to be controlled alternately. The presence of the keyboard with display allows to set up the system configuration quickly and easily, by selecting the number of motors to control, the setting of motor switch-on and switch-off delays, and to monitor the number of starting and the operating hours for each motor.

Functions

– Management of alternation between 3 or 4 motors

– 5 digital inputs for liquid level signaling (enable + 4 levels)

– 1 digital input to enable the operation with latch (every time a motor is activated, it remains active until the liquid drops below the minimum level probe)

– 4 relay outputs with NO contact for motor control

– Possibility to set motor switch-on and switch-off delays

– Monitoring of the number of starts and the operating hours of each motor.

Operational characteristics

– Operating limits: • LVMP30A024: 20.4...28.8VAC (47...63Hz) • LVMP30A240: 85...265VAC (47...63Hz)
