9.1. Malfunctions in the transmitter’s STOP circuit
If the green LED flashes rapidly and without interruption after you press START there may be a
malfunction in the transmitting unit’s STOP circuit. Test the radio remote control to verify the
functioning of the STOP circuit.
The test is very simple: while the LED is flashing, press the STOP button and then the START
button. The result should be one of the following:
A) If the STOP circuit is in order, the transmitter will resume its normal operation after you reset
the STOP button and press START.
B) If the LED continues to flash rapidly after the test, repeat the test (for a maximum of 4 times)
until the result is A or C.
C) If the LED flashes and displays the error message “STOP circuit fault”, contact an authorized
Service Centre.
9.2. Passive emergency
Passive emergency is a safety mode automatically assumed by the system when it detects a
malfunction (clause 9.2.7.3 EN 60204-32). The most common cause is a loss of RF connection
between receiver and transmitter lasting more than 0.5 seconds due to:
• Strong disturbances on the transmission channel or a significant attenuation of the RF signal
caused by an obstacle.
• Excessive distance between transmitter and receiver (out of range).
In all these situations, the receiver independently enters passive emergency mode, opens the E-
STOP circuit and disables all the controls.
9.3. Technical Assistance
In case of malfunctions in the radio remote control that are not addressed in this manual, contact
