DECTRO 500-PH2 is a device of detection evolution which permite to select, with a switch composed by a key, detection of 2 types of lines (distances adjusted to installation).
In standard (without key), it's detection of line 20 kV which is selected.
In specific, (with a clé - validated by the head of site for example) it's line 63 kV which is selected.
This choice is necessary for only one antenna of detection.
An antenna of detection for high voltage overhead electric lines
System of prevention which with a little antenna of detection placed in the end of boom before pole, indicate high voltage overheas electric line presence around excavator with blocking of all movements:
- without Forced function: we autorized to down
- with option Forced-function: we block all the movements, we can get going again by a support on the push button situated on a box of visualization in cabin.
DANGER: threshold of detection signalled by visual and audible alarms - blocking partial or total.
Distance of detection minimum from antenna to line 20 kV: 3 meters
Distance of detection minimum from antenna to line 63 kV: 5 meters
Threshold of detection is adjusted in factory but threre is a possibility during assembling to adapt and to fix the distance of protection according to use.
Visualization in cabin
In cabin,a box of visualization of the alarms (visual and audible).
2 leds of signalization
- working 20 kV (green led)
- working 63 kV (red led)
Assembling on all types of hydraulic excavator
Options:
1- possibility to add a flashing light or to connect an existing flashing light to signal around excavator, the presence of Danger.
2- Forced-function by a push button (only one button for the two lines).
