TERMINOLOGY

• 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 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.
• Seal-Spring
The Mini-top Series incorporates a seal-spring to maintain the sealing pressure when the valve is fully closed. The standard spring has 0.5 – 1 mm (.02” – .04”) flexibility to facilitate the full-closed adjustment.
