| 72 Optimal lubricant metering based on operating hours or lubrication impulse In contrast to the perma STAR VARIO (with battery pack), the perma STAR CONTROL is supplied with external power via cable. The operating status can be transmitted to a PLC and evaluated. The two integrated operating modes TIME and IMPULSE offer flexible use. In TIME mode, lubricant discharge is based on operating hours. In IMPULSE mode, a precisely defined quantity is dispensed as soon as voltage is supplied. The perma STAR CONTROL consists of an electromechanical drive and an LC with 60, 120 or 250 cm 3 of lubricant. The required mode is set on the drive. Lubrication is precise and temperature-independent at a counter pressure up to 6 bar. perma STAR CONTROL TIME and IMPULSE mode combined in a single system
