As unit is auto ramping to a faster speed the user can stop the increase in speed
by pressing the down arrow button. This changes the set speed to the present
actual value.
• As unit is auto ramping to a slower speed the user can stop the decrease in speed
by pressing the up arrow button. This changes the set speed to the present actual
value.
• HIGH SPEED / LOW SPEED LEDs - These indicate the stirrer's set range.
• OVERLOAD LED - This indicator will flash when an overload condition
is approached. This indicator will remain on when an overload condition is
reached and the stirrer is shut down.
Overload conditions will occur when:
• The torque demand is outside the unit's capabilities
(solution is too viscous).
• The unit overheats due to extended operation at very high
torque and/or speed demands.
When the overload condition is due to torque demand, the stirrer will
automatically reduce speed to reduce the load. If reduction in speed is not
sufficient to keep the load in the stirrer's capable range, then the stirrer will shut
down.
When the overload condition is due to overheating, the stirrer will not
automatically reduce speed. If the overload light is flashing and the speed has
not reduced from the set point, the load should be reduced by the operator.
In either case, if the stirrer completely shuts down due to an overload condition,
it can be reset by powering off the stirrer. If the stirrer has overheated then it
must cool down before it can be reset.
