WRONG HANDLING
Wrong handling protection prevents the operator from over passing the limits when incoming 3-phase power or
a single-phase motor are incorrectly connected.
When the operator turns in the opposite direction and reaches the wrong limit switch, the LED indicator
flashes-on and all the external commands are ignored by the electronic board.
To correct the problem when:
Stop LED OFF:

Check if the Stop button is properly connected on #8 and #9 or if a Normally Closed contact is used.

Verify if the Hoist is properly engaged and if the Hoist switch is closed (or if any external interlock device is
remained open)
EXTERNAL CONTROLS
Refer to the wiring diagram on page 20 before connecting power or any external device to the ECB. Neglecting
to use the proper terminals will result in complete damage to the ECB. If you are not certain about procedures,
please consult Manaras for assistance.
NOTE: Do not attempt correction by reversing wires on control station.
