PROBLEM: The rescue operation doesn’t start:
SOLUTION: Check that the 4thpole is closed.
Check that RED-G is powered.
Check that RED-G doesn’t show any fault, through the leds A and B on the RGCON board.
PROBLEM: When the emergency operation starts, but the car doesn’t run:
SOLUTION:
Check that the car is not at any floor level.
Check that the control panel commands the set-up operation and that gives the inverter
the low speed command.
Check that RED-G doesn’t show any fault, through the leds A and B on the RGCON board.
Check if the phase sequence device of the control panel is working properly.
If not, try to invert 2 output phases of RED-G device. If problem persists, use a N.O. contact
of RED-G device (for example CM1-NO1) to bypass the phase sequence device contact.
Check if the control panel shows an alarm due to the RED-G output voltage higher than
the normal protection limit.
In detail, the voltage can increase if there is a big single-phase load, which unbalances the
RED-G output phase voltage.
In this case, a solution is to apply 2 resistors to balance the load (for example 1kOhm
250W or higher power), connecting them respectively to terminals 1(KE1) – 3(KE1) and 3
(KE1) – 1(KE2), so that they are disabled during normal operation.
PROBLEM: The rescue operation starts, the car run, but it stops before reaching the
floor:
SOLUTION: Check the led A and B status on the RGCON Board, to see what is the protection
that tripped
