  • Overload (Lock) Protection The Mini-Top Series is equipped with a protection circuit against overload caused by for example the valve catching an alien substance. When an overload is detected, the Mini-Top stops supplying

MODEL: MRP6 MRP6 SPECIFICATIONS ES-4850 Rev.13 Page 3/5 http://www.m-system.co.jp/ power to the motor and the status LED blinks in 0.5 sec. intervals. The protection is reset automatically with applying opposite- direction input signal or turning the power off and restarting.

  • Restarting Timer The Mini-Top Series is equipped with a timer circuit which gives an interval period (0 – 10 seconds) between stop- restart actions to prevent the motor and other internal components from overheating. It is recommended to set a long restarting time when the ambient temperature and/or the temperature of flow material is high.
  • Electronic Limiter This model is equipped with electronic limiters in order to prevent mechanical locks when the input goes below 0 % or above 100 %. Limiters are set at approx. -0.5 % for the full-closed side, approx. 100.5 % for the full-open side.
