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.
