Ex-LTܲ

Designed specifically for explosive areas, the Ex-LTܲ offers all of the advantages of the tried and tested LTܲ system: cost-effectiveness and ease of assembly combined with high quality and safety standards.

Easily to integrate into existing lift control systems, and equipped with a clever mounting kit and adjustment auxiliaries, the Ex-LTܲ is convenient to use. The integration into the respective control system is largely identical, since only signals are used which are available in all control systems. Please read the product description for the standard LTܲ for an additional description of the device designs.

The Ex-LTܲ was developed as a safety light grid, but can also be used as a normal light grid, e.g. to control an Ex-protected automatic lift door (see separate instructions in the login area).

Explosion protection for zone 1, 2 and 22

Explosion technology patented by STRACK, which has been consistently developed for this model, has resulted in unusually small installation dimensions so that it can be used universally. Parts of the Ex-LTܲ which are attached to the car correspond according ATEX Directive to the

• unit group II
• unit category 2G
• temperature class T4 according to EN 50014

and can be used in zone 1 according to EN 1127-1,

and correspond to

• Unit group II
• Unit category 3D
• Temperature class T130°C according to EN 50281-1-1

and can be used in zone 22 according to EN 1127-1.

Sensor strips

Since 2009 the Ex-SLG sensor strips have been the new sensor strips of the Ex-LTܲ safety light grid. They are narrower than before and suitable for lifts in a very dirty environment or production lifts in, for example, sawmills and the chemical industry. The lenses consist of antistatic silicate glass which is highly resistant to scratching and frequent cleaning.

HAWAMON Behind-the-wall assembly kit

HWAMON provides a very simple and therefore quick, cost-effective installation option of the Ex-LTܲ sensor strips. HWAMON serves to mount the sensor strips behind the car wall. It consists of 2 or 3 clamp holders for each sensor strip which can be almost randomly moved in height. The adjustment of the sensor strips at a later date can be simply carried out from the inside of the car by means of spring adjustment screws.

AWAMON On-the-wall assembly kit

AWAMON provides a very simple and therefore quick, cost-effective installation option of the LTܲ sensor strips. AWAMON is simply screwed onto the car wall from the inside. Within the top area there must be a cutout placed in the car wall enabling a penetration of the connection cable incl plug. For this an edge protection section is included in the delivery. Required screws are also included in the delivery.

Additional Ex car operating panel

The optional Ex operating panel is used as an additional operating panel in the car. It includes an Ex indicator lamp “light grid interruption”, an Ex buzzer and an Ex “continue“ pushbutton. The cover plate consists of V2A, grain 240, includs engraving and M4 Torx screws with internal pin. The installation depth is 100 mm. An optional housing can also be supplied.

We will be pleased to produce other sizes and designs for you, e.g. with red and green LED control lamps.

Ex zone switch assembly kit for Ex-LTܲ

If zone switches are required (e.g. in case the full version is used) the STRACK Ex zone switch assembly kit can be used. The Ex zone switch kits are known for their flexibility and very small type of construction. The flange hangers (caddy clamps) with the preassembled solenoids are mounted to the rear of the car rail.
