1. If the collision indicator light is turning on, really need to check whether a collision, for

example, whether proximity switch is divorce, whether torch retaining cap and steel is touching.

If we only use torch retaining cap to detect collisions, separated from the protective cap

and cutting steel. Because there is no contact with torch retaining cap and steel, the meaning

that the collision has not take place, the collision indicator light should be take off.

If we only use proximity switch to detect collisions, parameter P13 should be set to 1,

the meaning that allow the use of proximity switch detects a collision signal. Under normal

circumstances, the collision indicator light is turning on when proximity switch is divorce; the

collision indicator light is breaking down when proximity switch is not divorce. If we use in scene,

the collision indicator light is breaking down when proximity switch is divorce, or the collision

indicator light is turning on when proximity switch is not divorce, it explain that the description

of the received signal and the normal, L09 need to set the value of the inverse. After parameter

is set correctly, proximity switch can accurately reflect the situation of collision.

If we use proximity switch and torch retaining cap to detect collisions at the same time,

need to check respectively each set whether can accurately reflect the situation of collision. If a

certain way is failing, please use their method by alone to troubleshoot and fix, until it can

accurately reflect the situation of collision.

2. If the collision indicator light is breaking off, please make some collision conditions

by man, check whether the collision indicator light can be turned on. For example, when we use

torch retaining cap to detect collisions, if we make torch retaining cap and cutting steel short

circuit by metal screwdriver, the collision indicator light should be turned on. Or when we use

proximity switch, if we make torch connector crooked by hand, make proximity switch take off,

the THC collision indicator light should be turned on. If make visible collision conditions by man

and the collision indicator light cannot be turned on, we need to check whether the parameters

can be set orderly.

Switching in lift motor safely: After the detection of THC collision has debug and used

normally, please remove all conditions which can made collision, at the same time, THC collision

indicator light should be broken off . Then turning off power source of THC and connecting the

lift motor cable.

Check whether direction of lift move is true: After motor cable has been linked,

power-on ,when check whether the button named 【▲】 in THC faceplate is pressed, observe

whether the lift body is rising; when the button named【▼】is pressed, observe whether the lift

body is declining. If the button named【▲】is pressed, the lift body is declining rather than
