11.1. Malfunctions in the transmitter’s STOP circuit
Once you’ve pressed START , in case a malfunction in the STOP circuit is detected, the transmitting
unit stops giving the mushroom push-button error code. Please test the radio remote control to verify
the functioning of the STOP circuit.
If after having restored the STOP button and pressed START again, the LED flashes and displays the
error message “STOP circuit fault”, please contact an authorized service center.
11.2. Passive Emergency
Passive emergency is a safety status that the system assumes automatically when it autonomously
detects a malfunction (
clause 9.2.7.3 EN 60204-32)
. The most common cause is that of a loss of RF
connection between the receiver and the 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).
The receiver enters the passive emergency mode on its own, opens the E-STOP circuit and disables
all the commands. In AFA mode, the radio remote control searches a free RF channel with which to
establish a valid link, within a 0.5s timeout.
