Checking for inclination

Make sure that the PG-1000 is mounted hori- zontally by the following checks.

1.Press the [TRUE] and [+] keys more than two seconds.

When the inclination is within ± 5° , STATUS LED lights and TRUE LED blinks.

: On

: Blinking

Figure 8 LED status when inclination is within ± 5°

If STATUS LED is off, the inclination is over ± 5° . In this case, relocate the sensor to where inclination becomes within ± 5° or use a levelling brock.

2.Press the [AUTO] and [TRUE] keys more than two seconds to return to the normal mode. The STATUS LED blinks while the sensor is being calibrated and lights when the calibration is completed (return to nor- mal mode). Do not operate the equipment while the LED is blinking; calibration will be incomplete.

Grounding

Ground the PG-1000 as follows to prevent in- terference:

•The ground wire should be as short as pos- sible.

•The ground wire should be about 1.25 sq and not contain steel.

•Use only a closed end lug.

CAUTION

Ground the equipment

to prevent loss of sensitivity.

Connect cables as shown in the Figure 8.

Leave sufficient slack in cables for mainte- nance and checking ease. If cables run outside the bridge run them through conduit to protect them from corrosion.
