PHASE FAILURE PROTECTOR

PHASE FAiLURE
This document describes the phase failure protector inside the
Prolyft PLE 30 and 40 series controllers
Phase Failure
- When all phases are present and in correct order LED no: 1 (On)
and LED no: 2 (Out) are lighten ON
- When phases are not in correct order LED no: 1 (On) and LED
no: 3 (Phs Seq.) are lighten ON. In this case the phases shall be
turned. This can be done by disconnecting the controller.
The power cord is equipped with a phase reverse plug.
Use a screwdriver to turn phases.
- In case of missing phases or when there is a voltage unbalance
of 15% or more between phases, LED no: 1 (On) and LED no: 4
(Asm.) are lighten ON. In this case the controllers main relay is
not activated.
Voltage Unbalance:
When the phase to phase voltage unbalance is less than the
adjusted value by the user, the output relay is activated.
If the unbalance value exceeds the limit value (5%-15%) (to be set
by the user), the output relay is switched OFF at the end of delay
time (0,1....10s) ( also to be set by the user ). LED No: 2 (Out) is
lighten OFF, and Asymmetry error LED no: 4 (Asm.) is lighten ON.
If the fault disappears within the delay time, the output relay is not
switched OFF.
The voltage unbalance occurs if the L1,L2,L3 are loaded
unequally. This can be caused by a non-uniform distribution of
loads on the lines. The voltage asymmetry causes a rise of the
motor temperature and a reduction of the rated motor power.
Voltage asymmetry limit values can be adjusted between 5% and
15%. The Hysteresis is fixed at 20%
Example:
Given 3x380V supply with 10% asymmetry, relay switches OFF at:
380 - (380 x 10%) = 342V
Relay switches ON at: 342 + (342 x 10% x 20%) = 348V

REMOTE CONTROL

A remote control for the PLE-030 series is available.
The master and connected slaves can be controlled with this
remote unit.
The remote should be plugged into link connector.
The remote works as a run button and emergency stop only.
Individual presets for each hoist have to be made with the pre-set
switches first.
