Device introductory information
11.1 Purpose of use and physical configuration
The AG-105 is an automatic utility locating transmitter
designed for the generation of the propagating electric
oscillations in the traces of the buried utilities using
electromagnetic method of the trace search.
Field of application:
- Housing maintenance and utilities sector;
- Communications industry;
- Electric power and heat supply industries;
- Gas supply.
The device is shown in the enclosure-case containing:
1 - information panel on the inner side of the cover;
2 - battery holder with the handle in the center for removing;
3 - push-button and LED indication panel.
11.2 Control and indication elements
See - Appendix С
11.2.1 Display (functional fields of the front panel)
«Electrical power supply field»
always
displays rough estimates of the power supply
source condition in the current mode of
operation using three coloured light emitting
indicators.
1) The results of energy potential
assessment of the power supply source
(feasible operability index with current energy
consumption level). Three categories of the
output voltage of the power supply source «U» are determined under the specific value of the
absorbed current in the actual operating mode:
-
green
colour of the indicator «U» – «nominal» voltage (high energy potential of the batteries or
powerful external source);
-
yellow
colour of the indicator «U» – «acceptable» voltage (medium energy potential of the
batteries);
-
red
colour of the indicator «U» – «cut-off» voltage (energy potential of the batteries almost
used up, possible «unexpected» shutdown).
2) The category of the ABSORBED CURRENT «I» rate is specified based on the concordance
between measured value of the current and the figure of the one of the three ranges specifically
set by the program for the actual operating mode:
-
green
colour of the indicator «I» – «low» absorbed current;
-
yellow
colour of the indicator «I» – «medium» absorbed current;
-
red
colour of the indicator «I» – «high» absorbed current.
