TROUBLESHOOTING

The control unit is fitted with two LEDs, one for each barrier

• when the two LEDs are off, the barrier is established;

• if one of the two LEDs is lit, the corresponding barrier is interrupted;

• if neither of the two LEDs can be lit, there is a power supply fault.

When the assembly is not complete and the LEDs are visible, it is convenient to make use of this indication to carry out alignment of the heads.

SYMPTOMS

LED B is permanently lit

LED A and/or LED B is permanently lit

PROBABLE CAUSES

Faulty connection

Faulty connection

Faulty alignment

Incorrect power supply

CORRECTIVE ACTIONS a. Check the connection of the emitter and receiver b. Check whether Dip-Switch 1 is in the OFF position (for the single barrier) a. Check the connection of the emitter and receiver b. Check the positions of the Dip-Switch c. Check using a voltmeter that the supply voltage is present d. Check the alignment of the emitter and receiver a. Check the connection of the output relay/transistor b. Check whether the Dip-Switches 1 and 2 are configured correctly

The LEDs are working, but the door does not respond

Faulty connection of the output relay/transistor

Other sources of malfunction

Checking the alignment of the emitter and receiver : a tolerance of 2 x 8° is normally possible; check that the range is not excessive

(10 metres maximum)

Checking the distance to the ground of the lower barrier : 20 cm minimum

When there are two barriers, check that the two barriers are correctly at least 30 cm apart

When there are two barriers, check if they are correctly crossed : the emitter of one barrier and the receiver of the other barrier must be situated in the same upright; check if the cabling has correctly associated an emitter with the receiver opposite it

DESCRIPTION

MICROCELL ONE, TWO, THREE USER’S GUIDE

The MICROCELL ONE, TWO and THREE infrared barriers are responding to the change in requirements in the area of providing safety of automatic doors for pedestrians. Because of their reduced size, they fit discreetly into all door profiles. Multiplication of microprocessor operators, definition of new safety standards and concern for better protection of pedestrians have led to the development of a new flexible, high-performance range.
