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.
• Full-open/-closed signal (limit switch contact)
The Mini-Top series is optionally equiped with
full-open/-closed signal that makes at full-open or -closed
position. These positions are NOT proportional to the span
and/or zero adjustments.
• Full-closed/overload signal (relay contact)
The Mini-Top series is optionally equiped with full-
closed/overload signal that makes at full-closed position
and/or detecting overload (see “Overload Protection”). This
full-closed position is proportional to the span and/or zero
adjustments.
