Microlynx 4 manual

High level of immunity Design of the unit was closely tied to the conditions of supply lines, which handle more disturbances every day.

In addition, these curves may be used for torque control starting of constant torque applications. It appears when Starting Voltage is displayed, the up arrow is pressed and Starting Voltage has reached its max. Too Many Starts: Starts Inhibit: Time period min, when starting is prevented, after too many starts fault Long Start Time stall Maximum allowable starting time sec.

Can be set to operate at all times, disabled or operate during Run only. Optional auto reset after time delay. Under Voltage: Trips when main voltage drops below V, time delay Sec.

Optional Auto Reset. Over Voltage: Trips when main voltage increase above V, time delay sec. A, B, C Preparation for bypass Bypass preparation is standard in all models.

Terminal L Control phase The control voltage operates the electronic circuitry and the fans when they exist. For fan power consumption, see technical specification in section 3 page Terminal 7 Programmable input — Energy Refer to section 4. Terminal 10 Immediate Relay N. Immediate Relay RUN relay is the immediate output relay.

Undercurrent DLY sec. Sets the time delay for Undercurrent FLT protection. Refer to section 8. Enabled will set the overload protection to be operative at all time. Disabled will set the overload protection not to be operative at all time. When Overload Protect is set to Disabled the motor is not protected for Overload!! Undervoltage DLY 1 —10 sec. Can not be set lower than the Undervoltage FLT setting. Overvoltage DLY 1 —10 sec. Sets Overvoltage Fault delay. Store Settings Main Settings.
