Contact: Wang 18913951307 QQ COM mistake crane remote control input lines and main lines are connected to the output of the total start a FireWire or a zero line, a connected FireWire, installation commissioning complete remote control when burned, the company reminded: 1, After customers buy Yu Ding remote control, please first carefully read the instructions before installing the crane remote control, familiar remote control output circuit diagram, make sure the remote control power supply voltage levels, find out the remote control output circuit principle. Note that the remote control output line is divided into two parts: a, receives the power supply itself is generally divided into AC 36V, AC 220V, AC 380V, DC 12V, DC 24V, DC 48V and so on. When the receiver power to DC, polarity marked press polarity wiring found reversed, the receiver power indicator does not light, adjust power immediately. b, the receiver output line: remote control receiver output lines is generally one or more common line (COM line, relay contacts input line), the rest of the relay contact output line, that is, between the input and output cables through the normally open contact relay connection, it is equivalent to a switch at both ends, so must not be connected to different voltage levels respectively on. 2, customers install Yu Ding remote control please professional electrician to install, do not live working. 3, make sure the correct wiring during commissioning, confirm that the device is in a safe state. 4, first turn off the main power supply device, a separate remote control receiver on the power supply, remote control separately for debugging, confirm normal, give the main power transmission equipment, for device linkage, front linkage debugging equipment, first make sure the device, personnel in a safe state, retains a sufficient safe distance, preferably with a controlled device mains, faced with an emergency, immediately pull down the total gate, and troubleshooting, re-commissioning.
